DESCRIPTION
The Microchip Technology Inc. 93LC66A/B are 4K-bit,
low voltage serial Electrically Erasable PROMs. The
device memory is configured as x8 (93LC66A) or
x16 bits (93LC66B). Advanced CMOS technology
makes these devices ideal for low power nonvolatile
memory applications. The 93LC66A/B is available in
standard 8-pin DIP, surface mount SOIC, and TSSOP
packages. The 93LC66AX/BX are only offered in a
150-mil SOIC package.
