Note:
When the ORG pin is connected to V_CC, x16 organization is
selected. When it is connected to ground, x8 organization
is selected. If the ORG pin is left unconnected, then an
internal pull-up device will select x16 organization.
DESCRIPTION
The CAT93C76 is an 8K-bit Serial EEPROM memory
device which is configured as either registers of 16
bits (ORG pin at V_CC or Not Connected) or 8 bits
(ORG pin at GND). Each register can be written (or
read) serially by using the DI (or DO) pin. The
CAT93C76 is manufactured using Catalyst’s
advanced CMOS EEPROM floating gate technology.
The device is designed to endure 1,000,000
program/erase cycles and has a data retention of 100
years. The device is available in 8-pin PDIP, SOIC,
TSSOP and 8-pad TDFN packages.
