DESCRIPTION
The Microchip Technology Inc. 93LC46AX/BX are 1K-
bit, low voltage serial Electrically Erasable PROMs. The
device memory is configured as x8 (93LC46A) or
x16 bits (93LC46B). Advanced CMOS technology
makes these devices ideal for low power nonvolatile
memory applications. The 93LC46AX/BX is available in
standard 8-pin DIP, 8-pin surface mount SOIC, and
TSSOP packages. The 93LC46AX/BX are offered only
in a 150-mil SOIC package.
