Description:

The Microchip Technology Inc. 93AA46/56/66 are 1K,

2K and 4K 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. The 93AA

Series is available in standard 8-pin PDIP and surface

mount SOIC packages. The rotated pin-out 93AA46X/

56X/66X are offered in the “SN” package only.
