? 2012 microchip technology inc. ds41672a-page 3 mtch810 1.0 device overview the microchip mtouch? mtch810 haptics feedback controller provides an easy way to add tactile feedback to any application. the device implements all the digital functions for a haptics feedback system. the haptic effects are designed to provide feedback for a ?button and slider? type capacitive touch interface. when combined with an analog power driver and an eccentric rotating mass (erm) style actuator, the resulting circuit comprises a complete tactile feedback haptic system. the device is controlled through an i 2 c slave interface. in response to a two-byte command, the mtch810 (in combination with the driver and erm) generates one of 13 different haptic vibration effects. the effects are 180-220 hz vibrations with different amplitude envelopes and durations. the effects create a variety of different ?feels? to provide feedback for different capacitive touch commands, status and error conditions. several effects are similar with different power levels in order to allow the users to compensate for the variations in the coupling of the vibrations to the user?s finger tip. two additional commands allow the termination of an effect early and the ability to read the effects table revision. 1.1 communications ?i 2 c, slave mode 1.2 drive outputs ? dr1 is a dedicated pwm output ? dr2 is a dedicated inverted pwm output 1.3 pwm resolution ? 10 bits 1.4 pin description 1.4.1 dr1 this is the enable/non-inverting digital pwm haptics drive output. it should be connected to the non-inverting input of a haptic power driver circuit design for erm actuators. the pwm output should only be active when an effect is in progress. 1.4.2 dr2 this is the inverting digital pwm haptics driver output. it should be connected to the inverting input of a haptic power driver circuit designed for erm actuators. the pwm output should only be active when an effect is in progress. 1.4.3 i 2 c ? serial data pin (sda) the sda pin is the serial data pin of the i 2 c interface. the sda pin is used to write or read the registers and configuration bits. the sda pin is an open-drain n- channel driver. therefore, it needs an external pull-up resistor from the v dd line to the sda pin. except for the start and stop conditions, the data on the sda pin must be stable during the high period of the clock. the high or low state of the sda pin can only change when the clock signal on the scl pin is low. refer to section 2.1.2 ?i 2 c operation? for more details on the i 2 c serial interface communication. 1.4.4 i 2 c ? serial clock pin (scl) the scl pin is the serial clock pin of the i 2 c interface. the i 2 c interface only acts as a slave and the scl pin accepts only external serial clocks. the input data from the master device is shifted into the sda pin on the rising edges of the scl clock, and the output from the device occurs at the falling edges of the scl clock. the scl pin is an open-drain n-channel driver. therefore, it needs an external pull-up resistor from the v dd line to the scl pin. refer to section section 2.1.2 ?i 2 c oper- ation? for more details on i 2 c serial interface communi- cation. for more details, see figure 1-1 and table 1-1 .
mtch810 ds41672a-page 4 ? 2012 microchip technology inc. 1.4.4.1 clock stretching a feature of the scl pin is clock stretching. this allows the i 2 c slave to hold communications at the end of each byte from the master. its purpose is to allow the slave sufficient time to process the data before the next byte is sent. it accomplishes the clock hold by turning on the open-drain output, holding the clock line low. this prevents the master from starting the transmission of the next byte in the packet. for proper operation, the i 2 c master must be capable of recognizing a clock stretch condition, and suspending transmission until the mtch810 releases the scl pin. 1.5 haptic commands the commands are transmitted via the i 2 c serial interface as a start condition, address plus write bit, two successive bytes and a stop condition. for the effect table revision number, the write command is followed by an i 2 c read of two bytes. tab l e 2 - 2 and table 2-3 list all the commands supported by the mtch810. 1.6 hardware to build a complete haptic system, the two digital pwm outputs must be filtered to produce a dc drive signal, and amplified to produce a minimum of 300 ma of drive at 3v. this output is then used to drive an erm actua- tor. figure 1-1 below shows a typical controller, driver and actuator combination for a haptic system. the mtch810 is the controller in the system, accepting i 2 c commands and generating the appropriate pwm signals to create the haptic effect. the outputs from the mtch810 are then filtered and amplified by the drv8601. the amplifier stage is essentially an audio frequency amplifier configured for differential inputs and outputs. the output of the amplifier then drives the erm. the rc network in the feedback path provides a pole in the transfer function at 160 hz to roll off the high frequency gain and attenuate the ripple at the pwm frequency. the connection between the dr1 output and the enable of the amplifier allows the controller to generate an output for the erm with a drive/coast format, rather than a drive/brake control. using a differential output eliminates the need for a large capacitor on the output to ac couple the drive signal to the erm. table 1-1 lists the qualified erm actuators and their manufacturers. note: the mtch810 includes a time-out function on the clock stretching function that will reset the i 2 c interface in the event that the i 2 c interface hangs in a clock stretch condition. note: any audio frequency drive circuits will work in the application, provided it can supply 300 ma at 3v and turn on in less than 1 ms. amplifiers with built-in ?click and pop? elimination have soft-start enables which have a turn on time of >10 ms and are not suitable for a haptic driver. table 1-1: approved act uators and specifications actuator dimensions (mm) rated voltage haptic transient overdrive voltage impedance nidec nrs-3388i 4.6 0.2d 15.6 0.9l 1.3v 0.2v 3.3v 10.6 ? 20% johnson electric 1999-1mb0037ep 6.0h x 8.0w 21.5l 4.5v 5.0v 10 ?? - typical

? 2012 microchip technology inc. ds41672a-page 7 mtch810 2.0 i 2 c? serial interface this device supports the i 2 c serial protocol. the i 2 c module operates in slave mode, so it does not generate the serial clock. 2.1 overview this i 2 c interface is a two-wire interface. figure 2-1 shows a typical i 2 c interface connection. the i 2 c interface specifies different communication bit rates. these are referred to as standard, fast or high speed modes. the mtch810 device supports these three modes. the bit rates of these modes are: ? standard mode: bit rates up to 100 kbit/s ? fast mode: bit rates up to 400 kbit/s a device that sends data onto the bus is defined as a transmitter, and a device receiving data is defined as a receiver. the bus has to be controlled by a master device which generates the serial clock (scl), controls the bus access and generates the start and stop conditions. the mtch810 device works as slave. both master and slave can operate as transmitter or receiver, but the master device determines which mode is activated. communication is initiated by the master (microcontroller) which sends the start bit, followed by the slave address byte. the first byte transmitted is always the slave address byte, which contains the device code, the address bits and the r/w bit. figure 2-1: typical i 2 c? interface the i 2 c serial protocol only defines the field types, field lengths, timings, etc. of a frame. the frame content defines the behavior of the device. for details on the frame content (commands/data) refer to section 2.3 ?i2c commands? . refer to the nxp user manual (um10204_3) for more details on the i 2 c specifications. 2.1.1 signal descriptions the i 2 c interface uses up to two pins (signals). these are: ? sda (serial data) (see section 1.4.3 ?i2c ? serial data pin (sda)? ) ? scl (serial clock) (see section 1.4.4 ?i2c ? serial clock pin (scl)? ) 2.1.2 i 2 c operation the mtch810 device i 2 c module is compatible with the nxp i 2 c specification. the following lists some of the module?s features: ? 7-bit slave addressing ? supports three clock rate modes: - standard mode, clock rates up to 100 khz - fast mode, clock rates up to 400 khz ? support multi-master applications the i 2 c 10-bit addressing mode is not supported. the nxp i 2 c specification only defines the field types, field lengths, timings, etc. of a frame. the frame content defines the behavior of the device. the frame content for this device is defined in section 2.3 ?i2c commands? . 2.1.3 i 2 c bit states and sequence figure 2-8 shows an i 2 c 8-bit transfer sequence, while figure 2-7 shows the bit definitions. the serial clock is generated by the master. the following definitions are used for the bit states: ? start bit (s) ? data bit ? acknowledge (a) bit (driven low)/ no acknowledge (a ) bit (not driven low) ? repeated start bit (sr) ? stop bit (p) 2.1.4 start bit the start bit (see figure 2-2 ) indicates the beginning of a data transfer sequence. the start bit is defined as the sda signal falling when the scl signal is high. figure 2-2: start bit scl scl mtch810 sda sda host controller typical i 2 c? interface connections sda scl s 1st bit 2nd bit
mtch810 ds41672a-page 8 ? 2012 microchip technology inc. 2.1.5 data bit the sda signal may change state while the scl signal is low. while the scl signal is high, the sda signal must be stable (see figure 2-3 ). figure 2-3: data bit 2.1.6 acknowledge (a) bit the a bit (see figure 2-4 ) is typically a response from the receiving device to the transmitting device. depending on the context of the transfer sequence, the a bit may indicate different things. typically, the slave device will supply an a response after the start bit and eight data bits have been received. an a bit has the sda signal low. figure 2-4: acknowledge waveform 2.1.7 not a (a ) response the a bit has the sda signal high. tab l e 2 - 1 shows the conditions where the slave device will issue a not a (a ). sda scl data bit 1st bit 2nd bit a 8 d0 9 sda scl table 2-1: mtch810 a / a responses event acknowledge bit response comment general call a slave address valid a slave address not valid a bus collision n/a treated as ?don?t care? if the collision occurs on the start bit. otherwise, i 2 c? resets.
? 2012 microchip technology inc. ds41672a-page 9 mtch810 2.1.8 repeated start bit the repeated start bit (see figure 2-5 ) indicates that the current master device wishes to continue communicating with the current slave device without releasing the i 2 c bus. the repeated start condition is the same as the start condition, except that the repeated start bit follows a start bit (with the data bits + a bit) and not a stop bit. the start bit is the beginning of a data transfer sequence and is defined as the sda signal falling when the scl signal is high. figure 2-5: repeat start condition waveform 2.1.9 stop bit the stop bit (see figure 2-6 ) indicates the end of the i 2 c data transfer sequence. the stop bit is defined as the sda signal rising when the scl signal is high. a stop bit resets the i 2 c interface of the mtch810 device. figure 2-6: stop condition receive or transmit mode 2.1.9.1 aborting a transmission if any part of the i 2 c transmission does not meet the command format, it is aborted. this can be intentionally accomplished with a start or stop condition. this is done so that noisy transmissions (usually an extra start or stop condition) are aborted before they corrupt the device. figure 2-7: typical 8-bit i 2 c? waveform format figure 2-8: i 2 c? data states and bit sequence note 1: a bus collision during the repeated start condition occurs if: ? sda is sampled low when scl goes from low-to-high. ? scl goes low before sda is asserted low. this may indicate that another master is attempting to transmit a data ? 1 ?. sda scl sr = repeated start 1st bit scl sda a / a p 1st bit sda scl s 2nd bit 3rd bit 4th bit 5th bit 6th bit 7th bit 8th bit p a / a scl sda start condition stop condition data allowed to change data or a valid

? 2012 microchip technology inc. ds41672a-page 11 mtch810 2.3 i 2 c commands the i 2 c protocol does not specify how commands are formatted, so this section specifies the mtch810 device i 2 c command formats and operation. the commands can be grouped into the following categories: ? effect commands ? revision and control commands the supported commands are shown in ta b l e 2 - 2 and table 2-3 . 2.3.1 effect commands effect commands are used to initiate a specific haptic effect. the command consists of two bytes which are the xor of one another. the effect begins with the completion of the i 2 c stop condition. 2.3.2 revision and control commands revision and control commands are used to either retrieve the current revision of the effects table within the controller, or to terminate early a haptic effect. just like the effect commands, the command codes are two?s compliments of one another. the terminate-early command is executed at the completion of the i 2 c stop condition. when the revision command is sent, the controller then formats the revision data and waits for an i 2 c read from the master. 2.3.3 aborting a command transmission a restart or stop condition in an expected data bit position will abort the current command sequence and data will not be written to the mtch810. write commands are automatically aborted if the binary xor checksum is not valid. 2.3.4 write command (normal and high voltage) the format of the command is shown in figure 2-10 . the mtch810 generates the a / a bits. a write command will only start a write cycle after a properly formatted write command has been received and the stop condition has occurred. figure 2-10: write random address command s 0 a i 2 c slave address write bit ap 0010000 0 0 0 01 0 0 1 a 1 1 1 10 1 1 1 command message
mtch810 ds41672a-page 12 ? 2012 microchip technology inc. 2.3.5 revision command the format of the revision command (see figure 2-11 ) includes the start condition, i 2 c control byte (with r/w bit set to 0 ), a bit, the first command byte, a bit, fol- lowed by the two?s compliment of the command byte, a repeated start bit, i 2 c control byte (with r/w bit set to 1 ) and the mtch810 device transmitting the requested data bytes one at a time, until the master sends a stop condition. the i 2 c control byte requires the r/w bit to be equal to a logic one (r/w = 1 ) in order to generate a read sequence. the data read will start with the most signif- icant byte (msb) of the revision date and automatically increment to the next byte after each byte request. the sequence is ended with the master generating a stop or restart condition. figure 2-11 shows the waveforms for a single read. 2.3.5.1 ignoring an i 2 c transmission and ?falling off? the bus the mtch810 device expects to receive complete, valid i 2 c commands and will assume that any command not defined as a valid command is due to a bus corruption and will enter a passive high condition on the sda signal. all signals will be ignored until the next valid start condition and control byte are received. figure 2-11: read revision command stop bit 1 1 1 0 i 2 c? slave address revision command d ddd d d dd a 1 d dddd ddd n 1 1 a read bit revision lsb note 1: master device is responsible for a / a signal. if a a signal occurs, the mtch810 will abort this transfer and release the bus. 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 0 p 0010000 0010000 i 2 c? slave address write bit 0 a s a sr repeated start bit 0 0 0 revision msb 1111001 0 a
