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 VCC) 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
