DESCRIPTION  
• 8-pin PDIP/SOIC and 14-pin SOIC package  
(SOIC in JEDEC and EIAJ standards)  
Temperature ranges supported  
The Microchip Technology Inc. 93LC46/56/66 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  
93LC46/56/66 is available in standard 8-pin DIP and 8/  
14-pin surface mount SOIC packages. The 93LC46X/  
56X/66X are only offered in an “SN” package.  
- Commercial (C):  
- Industrial (I):  
0°C to +70°C  
-40°C to +85°C
