DESCRIPTION  
The Microchip Technology Inc. 93LC56A/B are 2K-bit,  
low-voltage serial Electrically Erasable PROMs. The  
device memory is configured as x8 (93LC56A) or  
x16 bits (93LC56B). Advanced CMOS technology  
makes these devices ideal for low power nonvolatile  
memory applications. The 93LC56A/B is available in  
standard 8-pin DIP, surface mount SOIC, and TSSOP  
packages. The 93LC56AX/BX are only offered in a  
150-mil SOIC package.
