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.

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 an internal pull−up device will
select the x16 organization.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. The DC input voltage on any pin should not be lower than −0.5 V or higher than VCC + 0.5 V. During transitions, the voltage on any pin may
undershoot to no less than −1.5 V or overshoot to no more than VCC + 1.5 V, for periods of less than 20 ns.
