DESCRIPTION

The Microchip Technology Inc. 93LC56A/B are 2K-bit,

low-voltage serial Electrically Erasable PROMs. The

device memory is conﬁgured as x8 (93LC56A) or

x16 bits (93LC56B). Advanced CMOS technology

makes these devices ideal for low power nonvolatile

memory applications. The 93LC56A/B is available in

standard 8-pin DIP, surface mount SOIC, and TSSOP

packages. The 93LC56AX/BX are only offered in a

150-mil SOIC package.
