ISD4004 series 1 isd detailed description speech/sound quality the ISD4004 chipcorder series includes devices offered at 4.0, 5.3, 6.4, and 8.0 khz sampling fre- quencies, allowing the user a choice of speech quality options. increasing the duration within a product series decreases the sampling frequency and bandwidth, which affects sound quality. please refer to the ISD4004 series product summary table on the second page to compare filter pass band and product durations. the speech samples are stored directly into on-chip nonvolatile memory without the digitization and compression associated with other solutions. di- rect analog storage provides a natural sounding reproduction of voice, music, tones, and sound effects not available with most solid-state solu- tions. duration to meet end system requirements, the ISD4004 se- ries products are single-chip solutions at 8, 10, 12, 16 minutes. flash storage one of the benefits of isd?s chipcorder technology is the use of on-chip nonvolatile memory, which pro- vides zero-power message storage. the message is retained for up to 100 years (typically) without power. in addition, the device can be re-record- ed (typically) over 100,000 times. microcontroller interface a four-wire (sclk, mosi, miso, ss ) spi interface is provided for ISD4004 control and addressing functions. the ISD4004 is configured to operate as a peripheral slave device, with a microcontroller- based spi bus interface. read/write access to all the internal registers occurs through this spi inter- face. an interrupt signal (int ) and internal read- only status register are provided for handshake purposes. programming the ISD4004 series is also ideal for playback-only applications, where single or multiple message playback is controlled through the spi port. once the desired message configuration is created, du- plicates can easily be generated via an isd pro- grammer. pin descriptions voltage inputs (v cca , v ccd ) to minimize noise, the analog and digital circuits in the ISD4004 devices use separate power busses. these +3 v busses are brought out to separate pins and should be tied together as close to the supply as possible. in addition, these supplies should be decoupled as close to the package as possible. ground inputs (v ssa , v ssd ) the ISD4004 series utilizes separate analog and digital ground busses. the analog ground (v ssa ) pins should be tied together as close to the pack- age as possible and connected through a low- impedance path to power supply ground. the digital ground (v ssd ) pin should be connected through a separate low-impedance path to pow- er supply ground. these ground paths should be large enough to ensure that the impedance be- tween the v ssa pins and the v ssd pin is less than 3 . the backside of the die is connected to v ss through the substrate resistance. in a chip-on- board design, the die attach area must be con- nected to v ss or left floating.

ISD4004 series 3 isd non-inverting analog input (ana in+) this pin is the non-inverting analog input that trans- fers the signal to the device for recording. the an- alog input amplifier can be driven single ended or differentially. in the single-ended input mode, a 32 mvp-p (peak-to-peak) maximum signal should be capacitively connected to this pin for optimal signal quality. this capacitor value, together with the 3 k input impedance of ana in+, is selected to give cutoff at the low frequency end of the voice passband. in the differential-input mode, the maximum input signal at ana in+ should be 16 mvp-p for optimal signal quality. the circuit connections for the two modes are shown in fig- ure 2 on page 2. inverting analog input (ana in?) this pin is the inverting analog input that transfers the signal to the device for recording in the differ- ential-input mode. in this differential-input mode, a 16 mvp-p maximum input signal at ana in? should be capacitively coupled to this pin for op- timal signal quality as shown in the ISD4004 series ana in modes, figure 2. this capacitor value should be equal to the coupling capacitor used on the ana in+ pin. the input impedance at ana in? is nominally 56 k . in the single-ended mode, ana in? should be capacitively coupled to v ssa through a capacitor equal to that used on the ana in+ input. audio output (aud out) this pin provides the audio output to the user. it is capable of driving a 5 k impedance. it is recommended that this pin be ac coupled. note the audout pin is always at 1.2 volts when the device is powered up. when in play- back, the output buffer connected to this pin can drive a load as small as 5 k . when in record, a resistor connects aud- out to the internal 1.2 volt analog ground supply. this resistor is approximately 850 k , but will vary somewhat according to the sample rate of the device. this rel- atively high impedance allows this pin to be connected to an audio bus without loading it down. slave select (ss ) this input, when low, will select the ISD4004 device. master out slave in (mosi) this is the serial input to the ISD4004 device. the master microcontroller places data on the mosi line one half-cycle before the rising clock edge to be clocked in by the ISD4004 device. master in slave out (miso) this is the serial output of the ISD4004 device. this output goes into a high-impedance state if the device is not selected. serial clock (sclk) this is the clock input to the ISD4004. it is generat- ed by the master device (microcontroller) and is used to synchronize data transfers in and out of the device through the miso and mosi lines. data is latched into the ISD4004 on the rising edge of sclk and shifted out of the device on the falling edge of sclk. interrupt (int ) the ISD4004 interrupt pin goes low and stays low when an overflow (ovf) or end of message (eom) marker is detected. this is an open drain output pin. each operation that ends in an eom or over- flow will generate an interrupt including the mes- sage cueing cycles. the interrupt will be cleared the next time an spi cycle is initiated. the interrupt status can be read by an rint instruction. overflow flag (ovf) ?the overflow flag indi- cates that the end of the ISD4004?s analog mem- ory has been reached during a record or playback operation. end of message (eom) ?the end-of-message flag is set only during playback operation when an eom is found. there are eight eom flag position options per row.
ISD4004 series 4 voice solutions in silicon ? row address clock (rac) this is an open drain output pin that provides a sig- nal with a 200 ms period at the 8 khz sampling fre- quency. (this represents a single row of memory and there are 2400 rows of memory in the isd 4004 series devices.) this signal stays high for 175 ms and stays low for 25 ms when it reaches the end of a row. the rac pin stays high for 109.38 sec and stays low for 15.63 sec in message cueing mode (see page 5 for a more detailed description of message cueing). refer to the ac parameters ta- ble for rac timing information on other sample rate products. when a record command is first initiated, the rac pin remains high for an extra t raclo period. this is due to the need to load sample and hold circuits internal to the device. this pin can be used for message management techniques. external clock input (xclk) the external clock input for the ISD4004 products has an internal pull-down device. these products are configured at the factory with an internal sam- pling clock frequency centered to 1 percent of specification. the frequency is then maintained to a variation over the entire commercial tempera- ture and operating voltage ranges as defined by the minimum/maximum limits in the applicable ac parameters table. the internal clock has a tol- erance, over the extended temperature, industrial temperature and voltage ranges as defined by the minimum/maximum limits in the applicable ac parameters table. a regulated power supply is recommended for industrial temperature range parts. if greater precision is required, the device can be clocked through the xclk pin in table 1. these recommended clock rates should not be varied because the antialiasing and smoothing filters are fixed. thus, aliasing problems can occur if the sample rate differs from the one recommended. the duty cycle on the input clock is not critical, as the clock is immediately divided by two internally. if the xclk is not used, this input should be connected to ground. automute? feature (am cap) this pin is used in controlling the automute feature. the automute feature attenuates the signal when it drops below an internally set threshold. this helps to eliminate noise (with 6 db of attenuation) when there is no signal (i.e., during periods of silence). a 1 f capacitor to ground should be connected to the am cap pin. this capacitor becomes a part of an internal peak detector which senses the signal amplitude (peak). this peak level is compared to an internally set threshold to determine the auto- mute trip point. for large signals the automute at- tenuation is set to 0 db while 6 db of attenuation occurs for silence. the 1 f capacitor also affects the rate at which the automute feature changes with the signal amplitude (or the attack time). the automute feature can be disabled by connecting the am cap pin to v cca . table 1: external clock input clocking table part number sample rate required clock ISD4004-08m 8.0 khz 1024 khz ISD4004-10m 6.4 khz 819.2 khz ISD4004-12m 5.3 khz 682.7 khz ISD4004-16m 4.0 khz 512 khz
ISD4004 series 5 isd serial peripheral interface (spi) description the ISD4004 series operates from an spi serial inter- face. the spi interface operates with the following protocol. the data transfer protocol assumes that the mi- crocontroller?s spi shift registers are clocked on the falling edge of the sclk. with the ISD4004, data is clocked in on the mosi pin on the rising clock edge. data is clocked out on the miso pin on the falling clock edge. 1. all serial data transfers begin with the falling edge of ss pin. 2. ss is held low during all serial communica- tions and held high between instructions. 3. data is clocked in on the rising clock edge and data is clocked out on the falling clock edge. 4. play and record operations are initiated by enabling the device by asserting the ss pin low, shifting in an opcode and an address field to the ISD4004 device (refer to the op- code summary on the page 6). 5. the opcodes and address fields are as fol- lows: <8 control bits> and <16 address bits>. 6. each operation that ends in an eom or overflow will generate an interrupt, includ- ing the message cueing cycles. the inter- rupt will be cleared the next time an spi cycle is initiated. 7. as interrupt data is shifted out of the ISD4004 miso pin, control and address data is simultaneously being shifted into the mosi pin. care should be taken such that the data shifted in is compatible with current system operation. it is possible to read interrupt data and start a new opera- tion within the same spi cycle. 8. an operation begins with the run bit set and ends with the run bit reset. 9. all operations begin with the rising edge of ss . message cueing message cueing allows the user to skip through messages, without knowing the actual physical lo- cation of the message. this operation is used dur- ing playback. in this mode, the messages are skipped 1600 times faster than in normal play- back mode. it will stop when an eom marker is reached. then, the internal address counter will point to the next message.
ISD4004 series 6 voice solutions in silicon ? 1. message cueing can be selected only at the beginning of a play operation. 2. as the interrupt data is shifted out of the ISD4004, control and address data is being shifted in. care should be taken such that the data shifted in is compatible with current system operation. it is possible to read interrupt data and start a new operation at the same time. see figure 5 through figure 8 for opcode format. power-up sequence the ISD4004 will be ready for an operation after t pud (25 ms approximately for 8 khz sample rate). the user needs to wait t pud before issuing an opera- tional command. for example, to play from ad- dress 00 the following programing cycle should be used. playback mode 1. send powerup command. 2. wait t pud (power-up delay). 3. send setplay command with address 00. 4. send play command. the device will start playback at address 00 and it will generate an interrupt when an eom is reached. it will then stop playback. record mode 1. send powerup command. 2. wait t pud (power-up delay). 3. send powerup command. 4. send setrec command with address 00. 5. send rec command. the device will start recording at address 00 and it will generate an interrupt when an overflow is reached (end of memory array). it will then stop re- cording. table 2:opcode summary instruction opcode <8 bits> address <16 bits> operational summary powerup 00100xxx power-up: device will be ready for an operation after t pud . setplay 11100xxx initiates playback from address . play 11110xxx playback from the current address (until eom or ovf). setrec 10100xxx initiates a record operation from address . rec 10110xxx records from current address until ovf is reached. setmc 11101xxx initiates message cueing (mc) from address . mc 1 11111xxx performs a message cue. proceeds to the end of the current message (eom) or enters ovf condition if no more messages are present. stop 0x110xxx stops current operation. stoppwrdn 0x01xxxx stops current operation and enters stand-by (power-down) mode. rint 2 0x110xxx read interrupt status bits: overflow and eom.
