DESCRIPTION 2 The X24165 is a CMOS 16,384 bit serial E PROM, internally organized 2048 x 8. The X24165 features a serial interface and software protocol allowing operation on a simple two wire bus. Three device select inputs (S0, S1, S2) allow up to eight devices to share a common two wire bus.
A Write Protect Register at the highest address location, 7FFh, provides three new write protection
features: Software Write Protect, Block Write Protect, and Hardware Write Protect. The Software Write Protect feature prevents any nonvolatile writes to the X24165 until the WEL bit in the write protect register is set. The Block Write Protection feature allows the user to individually write protect four blocks of the array by programming two bits in the write protect register. The Programmable Hardware Write Protect feature allows the user to install the X24165 with WP tied to VCC, program the entire memory array in place, and then enable the hardware write protection by programming a WPEN bit in the write protect register. After this, selected blocks of the array, including the write protect register itself, are permanently write protected. Xicor E PROMs are designed and tested for applications requiring extended endurance. Inherent data

PIN DESCRIPTIONS Serial Clock (SCL) The SCL input is used to clock all data into and out of the device. Serial Data (SDA) SDA is a bidirectional pin used to transfer data into and out of the device. It is an open drain output and may be wire-ORed with any number of open drain or open collector outputs. An open drain output requires the use of a pull-up resistor. For selecting typical values, refer to the PullUp Resistor selection graph at the end of this data sheet.

Device Select (S0, S1, S2) The device select inputs (S0,S1,S2) are used to set the first three bits of the 8-bit slave address. This
allows up to eight X24165's to share a common bus. These inputs can be static or actively driven. If used statically they must be tied to VSS or VCC as appropriate. If actively driven, they must be driven with CMOS levels (driven to VCC or VSS). Write Protect (WP) The write protect input controls the hardware write protect feature. When held LOW, hardware write protection is disabled and the X24165 can be written normally. When this input is held HIGH, and the WPEN

DEVICE OPERATION The X24165 supports a bidirectional bus oriented protocol. The protocol defines any device that sends data
onto the bus as a transmitter, and the receiving device as the receiver. The device controlling the transfer is a master and the device being controlled is the slave. The master will always initiate data transfers, and provide the clock for both transmit and receive operations. Therefore, the X24165 will be considered a slave in all
Clock and Data Conventions
Data states on the SDA line can change only during SCL LOW. SDA state changes during SCL HIGH are reserved for indicating start and stop conditions. Refer to Figures 1 and 2. Start Condition All command are preceded by the start condition, which is a HIGH to LOW transition of SDA when SCL is HIGH. The X24165 continuously monitors the SDA and SCL lines for the start condition and will not respond to
applications.

Stop Condition
All communications must be terminated by a stop condition, which is a LOW to HIGH transition of SDA The X24165 will respond with an acknowledge after recognition of a start condition and its slave address. If both the device and a write operation have been selected, the X24165 will respond with an acknowledge after the receipt of each subsequent eight-bit word.
when SCL is HIGH. The stop condition is also used to place the device into the standby power mode after a
read sequence. A stop condition can only be issued after the transmitting device has released the bus. Acknowledge Acknowledge is a software convention used to indicate successful data transfer. The transmitting device, either master or slave, will release the bus after transmitting eight bits. During the ninth clock cycle the receiver will pull the SDA line LOW to acknowledge that it received the eight bits of data. Refer to Figure 3.
In the read mode the X24165 will transmit eight bits of data, release the SDA line and monitor the line for an
acknowledge. If an acknowledge is detected and no stop condition is generated by the master, the X24165 will
continue to transmit data. If an acknowledge is not detected, the X24165 will terminate further data trans -missions.
The master must then issue a stop condition to return the X24165 to the standby power mode and place the device into
a known state.

DEVICE ADDRESSING Following a start condition the master must output the address of the slave it is accessing (see Figure 4). The
next three bits are the device select bits. A system could have up to eight X24165's on the bus. The eight addresses are defined by the state of the S0, S1 and S2 inputs. S1 of the slave address must be the inverse The last bit of the slave address defines the operation to be performed. When set HIGH a read operation is
selected, when set LOW a write operation is selected.
Following the start condition, the X24165 monitors the SDA bus comparing the slave address being transmitted
of the S1 input pin. Figure 4. Slave Address
DEVICE TYPE
with its slave address device type identifier. Upon a correct compare the X24165 outputs an acknowledge on the SDA line. Depending on the state of the R/W bit, the X24165 will execute a read or write operation.

For a write operation, the X24165 requires a second address field. This address field is the word address, comprised of eight bits, providing access to any one of 2048 words in the array. Upon receipt of the word address, the
X24165 responds with an acknowledge and awaits the next eight bits of data, again responding with an acknowledge
6551 ILL F07.2
The next three bits of the slave address are an extension of the array's address and are concatenated with
the eight bits of address in the word address field, providing direct access to the whole 2048 x 8 array.
The master then terminates the transfer by generating a stop condition, at which time the X24165 begins the internal write cycle to the nonvolatile memory. While the internal write cycle is in progress the X24165 inputs
are disabled, and the device will not respond to any requests from the master. Refer to Figure 5 for the address,
acknowledge and data transfer sequence.

Page Write
The X24165 is capable of a 32 byte page write operation. It is initiated in the same manner as the byte write operation, but instead of terminating the write cycle after the first data word is transferred, the master can transmit up to fifteen more words. After the receipt of each word, the X24165 will respond with an acknowledge. After the receipt of each word, the five low order ad- dress bits are internally incremented by one. The high order bits of the word address remain constant. If the master should transmit more than 32 words prior to generating the stop condition, the address counter will "roll over" and the previously written data will be over- written. As with the byte write operation, all inputs are disabled until completion of the internal write cycle. Refer to Figure 6 for the address, acknowledge and data transfer sequence.

Acknowledge Polling The Max Write Cycle Time can be significantly reduced using Acknowledge Polling. To initiate Acknowledge Polling, the master issues a start condition followed by the Slave Address Byte for a write or read operation. If the device is still busy with the high voltage cycle, then no ACK will be returned. If the device has completed the write operation, an ACK will be returned and the host can then proceed with the read or write operation.

READ OPERATIONS
Read operations are initiated in the same manner as Write operations with the exception that the R/W bit of the slave address is set HIGH. There are three basic read operations: current address read, random read terminated by the master; by not responding with an acknow -ledge and by issuing a stop condition. Refer to Figure 7 for the sequence of address, acknowledge and data transfer. Random Read Random read operations allow the master to access any memory location in a random manner. Prior to issuing the slave address with the R / W bit set HIGH, the master must first perform a "dummy" write operation. The master issues the start condition, and the slave address with the R/W bit set LOW, followed by the word address it is to read. After the word address acknowledge, the master immediately reissues the start condition and the slave address with the R/W bit set HIGH. This will be followed by an acknowledge from the X24165 and then by the eight-bit word. The read operation is terminated by the master; by not responding with an acknowledge and by issuing a stop condition. Refer to Figure 8 for the address, acknowledge and data transfer sequence.
and sequential read.
It should be noted that the ninth clock cycle of the read operation is not a "don't care." To terminate a read
operation, the master must either issue a stop condition during the ninth cycle or hold SDA HIGH during the
ninth clock cycle and then issue a stop condition.
Current Address Read Internally the X24165 contains an address counter that maintains the address of the last word read, incremented by one or the exact address of the last word written. Therefore, if the last access read was to address n, the
next read operation would access data from address n + 1. Upon receipt of the slave address with the R/W
set HIGH, the X24165 issues an acknowledge and transmits the eight-bit word. The read operation is

Sequential Read Sequential reads can be initiated as either a current address read or random access read. The first word is transmitted as with the other modes, however, the master now responds with an acknowledge, indicating it requires additional data. The X24165 continues to output data for each acknowledge received. The read operation is terminated by the master; by not responding with an acknowledge and then issuing a The data output is sequential, with the data from address n followed by the data from n + 1. The address counter for read operations increments all address bits, allowing the entire memory contents to be serially read during one operation. At the end of the address space (address 2047), the counter "rolls over" to 0 and the X24165 continues to output data for each acknowledge received. Refer to Figure 9 for the address,

WEL and RWEL are volatile latches that power-up in the LOW (disabled) state. A write to any address other than 7FFh, where the Write Protect Register is located, will be ignored (no ack) until the WEL bit is set HIGH. The WEL bit is set by writing 0000001x to address 7FFh. Once set, WEL remains HIGH until either reset (by writing 00000000 to 7FFh) or until the part powers-up again. The RWEL bit controls writes to
the block protect bits. RWEL is set by first setting WEL = 1 and then writing 0000011x to address 7FFh. RWEL must be set in order to change the block protect bits, BP0 and BP1, or the WPEN bit. RWEL is reset
