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 CAT93C46/56/57/66/86 are 1K/2K/2K/4K/16K-bit

Serial EEPROM memory devices which are configured

as either registers of 16 bits (ORG pin at V_CC) or 8 bits

(ORGpinatGND). Eachregistercanbewritten(orread)

serially by using the DI (or DO) pin. The CAT93C46/56/

57/66/86 are manufactured using Catalyst’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.
