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.  
1K (128 x 8 or 64 x 16)  
2K (256 x 8 or 128 x 16)
