CAT93C46
1 Kb Microwire Serial
EEPROM
Description
The CAT93C46 is a 1 Kb Serial EEPROM memory device which is
configured as either 64 registers of 16 bits (ORG pin at VCC) or 128
registers of 8 bits (ORG pin at GND). Each register can be written (or
read) serially by using the DI (or DO) pin. The CAT93C46 features a
selftimed internal write with autoclear. Onchip PowerOn Reset
circuit 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.

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.
