Description  
The AT93C46A provides 1024 bits of serial electrically erasable programmable read  
only memory (EEPROM) organized as 64 words of 16 bits each. The device is opti-  
mized for use in many industrial and commercial applications where low power and  
low voltage operation are essential. The AT93C46A is available in space saving 8-pin  
PDIP, 8-pin JEDEC, and 8-Pin TSSOP packages.  
AT93C46A  
The AT93C46A 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 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.
