CAT93C46R

1 kb Microwire Serial

EEPROM

Description

The CAT93C46R is a 1 kb CMOS Serial EEPROM device which is

organized as either 64 registers of 16 bits or 128 registers of 8 bits, as

determined by the state of the ORG pin. The CAT93C46R 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.

In contrast to the CAT93C46, the CAT93C46R features an internal

instruction clock counter which provides improved noise immunity

for Write/Erase commands.

x16 organization is selected. When it is connected

to ground, the x8 pin is selected. If the ORG pin is

left unconnected, then an internal pull−up device will

select the x16 organization.
