The Microchip Technology Inc. 93LC76/86 are 8K and  
16K low voltage serial Electrically Erasable PROMs.  
The device memory is configured as x8 or x16 bits  
depending on the ORG pin setup. Advanced CMOS  
technology makes these devices ideal for low power  
non-volatile memory applications. These devices also  
have a Program Enable (PE) pin to allow the user to  
write protect the entire contents of the memory array.  
The 93LC76/86 is available in standard 8-pin DIP and  
8-pin surface mount SOIC packages.
