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 the ORG pin is tied to ground). The device is optimized for use in many indus-

trial and commercial applications where low-power and low-voltage operations are

essential. The AT93C46/56/66 is available in space-saving 8-lead PDIP, 8-lead

JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead MAP, 8-lead TSSOP, and 8-lead dBGA2

packages.

The AT93C46/56/66 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 DO pin. 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.

Note: 1. This device is not recom-

mended for new designs.

Please refer to AT93C56A.

2. This device is not recom-

mended for new designs.

Please refer to AT93C66A.

The AT93C46/56/66 is available in 2.7V to 5.5V and 1.8V to 5.5V versions.
