DESCRIPTION

The CAT93C66 is a 4-Kb CMOS Serial EEPROM

device which is organized as either 256 registers of 16

bits (ORG pin at V

) or 512 registers of 8 bits (ORG

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

serially by using the DI (or DO) pin. The CAT93C66

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 organization is

selected. If the ORG pin is left unconnected, then an internal pullup

device will select the x16 organization
