DESCRIPTION  
CMOS EEPROM floating gate technology. The devices  
aredesignedtoendure1,000,000program/erasecycles  
and have a data retention of 100 years. The devices are  
available in 8-pin DIP, 8-pin SOIC or 8-pin TSSOP  
packages.  
The 93LC46/56/57/66/86 are 1K/2K/2K/4K/16K-bit  
Serial EEPROM memory devices which are configured  
as either registers of 16 bits (ORG pin at VCC) or 8 bits  
(ORGpinatGND). Eachregistercanbewritten(orread)  
serially by using the DI (or DO) pin. The 93LC46/56/  
57/66/86 are manufactured using TMC’s advanced

Note: When the ORG pin is connected to VCC, the x16 organiza-  
tion is selected. When it is connected to ground, the x8 pin  
is selected. If the ORG pin is left unconnected, then an  
internal pullup device will select the x16 organization.
