DESCRIPTION

The CAT93C56/57 is a 2-Kb CMOS Serial EEPROM

device which is organized as either 128 registers of 16

bits (ORG pin at V

) or 256 registers of 8 bits (ORG pin

at GND). Each register can be written (or read) serially

by using the DI (or DO) pin. The CAT93C56/57 features

sequential read and self-timed internal write with auto-

clear. On-chip Power-On Reset circuitry protects the

internal logic against powering up in the wrong state.

Note: When the ORG pin is connected to VCC, the x16 organization

is selected. When it is connected to ground, the x8 pin is selected. If

the ORG pin is left unconnected, then am internal pullup device will

select the x16 organization
