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.  
AT93C46  
AT93C56(1)  
AT93C66(2)  
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.
