2. Description

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

mable read-only memory (EEPROM) 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 industrial and

commercial applications where low-power and low-voltage operations are essential.

The AT93C56A/66A is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-

lead EIAJ SOIC,

Grid Array (ULA), 8-lead TSSOP, and 8-ball dBGA2 packages.

The AT93C56A/66A is enabled through the Chip Select pin (CS) 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 and 1.8V to 5.5V versions.
