Description:

The Microchip Technology Inc. 93LC46/56/66 are 1K, 2K and 4K low voltage serial Electrically Erasable PROMs (EEPROM). The device memory is configured as x8 or x16 bits depending on the external logic of levels of the ORG pin. Advanced CMOS technology makes these devices ideal for low power nonvolatile memory applications. The 93LC Series is available in standard 8-pin PDIP and surface mount SOIC packages. The rotated pin-out 93LC46X/56X/66X are offered in the “SN” package only.
