Description:
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
nonvolatile 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 PDIP and
8-pin surface mount SOIC packages.
