Features
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 it 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, 8-lead MAP, 8-lead TSSOP, and 8-ball dBGA2™ packages.

... DC Output Current........................................................ 5.0 mA Block Diagram 2 The AT93C56A/66A is enabled through the Chip Select pin (CS) and accessed via a 3-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 ...

... DO. Output data changes are synchronized with the rising edges of serial clock SK. It should be noted that a dummy bit (logic “0”) precedes the 8- or 16-bit data output string. The AT93C56A/66A supports sequential read operations. The device will automatically increment the inter- nal address pointer and clock out the next memory location as long as Chip Select (CS) is held high. In this case, the dummy bit (logic “ ...
