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.
