... Serial E PROM DESCRIPTION The X24C02 is CMOS a 2048 bit serial E internally organized 256 x 8. The X24C02 features a serial interface and software protocol allowing operation on a simple two wire bus. Three address inputs allow up to eight devices to share a common two wire bus. 2 Xicor E PROMs are designed and tested for applica- tions requiring extended endurance ...

... 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. There- fore, the X24C02 will be considered a slave in all applications. Figure 1. Data Validity SCL ...

... X24C02 will respond with an acknowledge after the receipt of each subsequent eight bit word. In the read mode the X24C02 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 X24C02 will continue to transmit data ...

... SDA bus comparing the slave address being transmit- ted with its slave address (device type and state and A 1 outputs an acknowledge on the SDA line. Depending on the state of the R/W bit, the X24C02 will execute a read or write operation. WRITE OPERATIONS Byte Write For a write operation, the X24C02 requires a second A0 R/W address field ...

... X24C02 Page Write The X24C02 is capable of a four byte page write opera- tion 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 three more words. After the receipt of each word, the X24C02 will respond with an acknowledge ...

... R/W bit set to one. This will be followed by an acknowledge from the X24C02 and then by the eight bit word. The master terminates this transmission by issuing a stop condition, omitting the ninth clock cycle acknowledge. Refer to Figure 8 for the address, acknowledge and data transfer sequence ...

... At the end of the address space (address 255), the counter “rolls over” to address 0 and the X24C02 continues to output data for each acknowledge received. Refer to Figure 9 for the address, acknowl- edge and data transfer sequence. ...

... The write cycle time is the time from a valid stop condition of a write sequence to the end of the internal erase/program cycle. During the write cycle, the X24C02 bus interface circuits are disabled, SDA is allowed to remain high, and the device does not respond to its slave address. ...
