... X24164 2 Serial E PROM DESCRIPTION The X24164 is a CMOS 16,384 bit serial E internally organized 2048 x 8. The X24164 features a serial interface and software protocol allowing operation on a simple two wire bus. Three device select inputs (S devices to share a common two wire bus. 2 Xicor E PROMs are designed and tested for applica- tions requiring extended endurance ...

... The device select inputs ( second, third and fourth bits of the 8 bit slave address. This allows up to eight X24164’s to share a common bus. These inputs can be static or actively driven. If used statically they must be tied actively driven, they must be driven to V ...

... 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 X24164 will be considered a slave in all applications. Figure 1. Data Validity SCL SDA ...

... X24164 will respond with an acknowledge after the receipt of each subsequent eight bit word. In the read mode the X24164 will transmit eight bits of data, release the SDA line and monitor the line for an acknowledge acknowledge is detected and no stop condition is generated by the master, the X24164 will continue to transmit data ...

... The master then terminates the transfer by generating a stop condition, at which time the X24164 begins the internal write cycle to the nonvolatile memory. While the internal write cycle is in progress the X24164 inputs are disabled, and the device will not respond to any requests from the master ...

... X24164 initiates the internal write cycle. ACK polling can be initiated immediately. This involves issuing the start condition followed by the slave address for a write operation. If the X24164 is still busy with the write operation no ACK will be returned. If the X24164 has completed the write operation an ACK will be returned and the host can then proceed with the next read or write operation ...

... R/W bit set to one. This will be followed by an acknowledge from the X24164 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. ...

... At the end of the address space (address 2047), the counter “rolls over” and the X24164 continues to output data for each acknowledge re- ceived. Refer to Figure 9 for the address, acknowledge and data transfer sequence ...
