Description  
The Atmel® AT93C56B/66B provides 2048/4096 bits of serial electrically erasable pro-  
grammable 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 the  
ORG pin is tied to ground). The device is optimized for use in many industrial and commer-  
cial applications where low-power and low-voltage operations are essential. The  
AT93C56B/66B is available in space-saving 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead  
UDFN, 8-lead XDFN, and 8-ball VFBGA packages.  
Atmel AT93C56B  
Atmel AT93C66B  
The AT93C56B/66B 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 data output pin, DO. The write cycle is completely self-timed, and no sep-  
arate 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.  
The AT93C56B/66B operates from 1.7V to 5.5V.
