DESCRIPTION
The Microchip Technology Inc. 93AA76/86 are 8K and
16K low voltage serial Electrically Erasable PROMs.
The device memory is conï¬gured 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 93AA76/86 is available in standard 8-pin DIP and
8-pin surface mount SOIC packages.
