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.
