Description

The AT93C46/56/66 provides 1024/2048/4096 bits of serial electrically erasable pro-

grammable read only memory (EEPROM) organized as 64/128/256 words of 16 bits

each, when the ORG pin is connected to VCC and 128/256/512 words of 8 bits each

when it is tied to ground. The device is optimized for use in many automotive applica-

tions where low power and low voltage operations are essential. The AT93C46/56/66

is available in space-saving 8-lead PDIP and 8-lead JEDEC SOIC packages. The

AT93C46/56/66 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. The Write cycle is only

enabled when it is in the Erase/Write Enable state. When CS is brought “high” follow-

ing the initiation of a write cycle, the DO pin outputs the Ready/Busy status.
