DESCRIPTION
The CAT93C56/57 are 2K-bit Serial EEPROM memory
devices which are configured as either registers of 16
bits (ORG pin at V
CC
) or 8 bits (ORG pin at GND). Each
register can be written (or read) serially by using the
DI (or DO) pin. The CAT93C56/57 are manufactured
using Catalyst’s advanced CMOS EEPROM floating
gate technology. The devices are designed to endure
1,000,000 program/erase cycles and has a data reten-
tion of 100 years. The devices are available in 8-pin DIP,
SOIC, TSSOP and 8-pad TDFN packages.

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.
