Description

The AT93C56A/66A provides 2048/4096 bits of serial electrically erasable program-

mable 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 the ORG pin 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 PDIP and 8-lead JEDEC

SOIC packages.

AT93C56A

AT93C66A

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.

Preliminary

The AT93C56A/66A is available in 4.5V to 5.5V and 2.7V to 5.5V versions.
