4Kbit, 3-wire Bus Serial Automotive EEPROM with sequential read, supports x8 or x16 data format memory organization.

The AT93C56A/66A provides 2048/4096 bits of serial electrically-erasable programmable read-only memory (EEPROM). The EEPROM is organized as 128/256 words of 16 bits each when the ORG pin is connected to VCC and 256/512 words of 8 bits each when it is tied to ground. The device is optimized for use in many automotive applications where low-power and low-voltage operations are essential. The AT93C56A/66A is available in space-saving 8-lead JEDEC SOIC and 8-lead TSSOP packages. The AT93C56A/66A is enabled through the Chip Select (CS) pin and accessed via a three-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK). Upon receiving a Read instruction at DI, the address is decoded and the data is clocked out serially on the data output pin DO. The write cycle is completely self-timed and no separate erase cycle is required before write. The write cycle is only enabled when the part is in the Erase/Write Enable state. When CS is brought high following the initiation of a write cycle, the DO pin outputs the Ready/Busy status of the part. The AT93C56A/66A is available in 2.7V to 5.5V versions.
