... Die Sales: Wafer Form, Waffle Pack, and Bumped Wafers. Description The AT24C02A/04A provides 2048/4096 bits of serial electrically erasable and program- mable read-only memory (EEPROM) organized as 256/512 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low- power and low-voltage operation are essential ...

... DEVICE/PAGE ADDRESSES (A2, A1, A0): The A2, A1 and A0 pins are device address inputs that must be hardwired for the AT24C02A. As many as eight 2K devices may be addressed on a single bus system. (Device addressing is discussed in detail under Device Addressing, page 8). ...

... Upper Half (1K) Array CC At GND AT24C02A, 2K SERIAL EEPROM: The 2K is internally organized with 32 pages of 8 bytes each. Random word addressing requires an 8-bit data word address. AT24C04A, 4K SERIAL EEPROM: The 4K is internally organized with 32 pages of 16 bytes each. Random word addressing requires a 9-bit data word address. ...

... The EEPROM sends a “0” to acknowledge that it has received each word. This happens during the ninth clock cycle. STANDBY MODE: The AT24C02A/04A/08A/16A features a low-power standby mode that is enabled: (a) upon power-up and (b) after the receipt of the Stop bit and the com- pletion of any internal operations. ...

... Device Addressing Write Operations AT24C02A/04A 8 The 2K and 4K EEPROM devices require an 8-bit device address word following a start condition to enable the chip for a read or write operation, as shown in Figure 7. Figure 7. Device Address 2K 1 MSB 4K 1 The device address word consists of a mandatory “1”, “0” sequence for the first four most significant bits as shown ...

... EEPROM inputs are disabled, acknowledge polling can be initiated. This involves send- ing a start condition followed by the device address word. The read/write bit is representative of the operation desired. Only if the internal write cycle has completed will the EEPROM respond with a “0” allowing the read or write sequence to continue.

... Read Operations AT24C02A/04A 10 Read operations are initiated the same way as write operations with the exception that the read/write select bit in the device address word is set to “1”. There are three read operations: current address read, random address read and sequential read. ...

... Figure 12. Sequential Read 0976Q–SEEPR–8/05 tial read will continue. The sequential read operation is terminated when the microcontroller does not respond with a “0” but does generate a following stop condition, see Figure 12. AT24C02A/04A 11 ...
