CAT93C46
1 kb Microwire Serial
EEPROM
Description
configured as either 64 registers of 16 bits (ORG pin at V
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
self−timed internal write with auto−clear. On−chip Power−On Reset
circuit protects the internal logic against powering up in the wrong
state.

to ground, the x8 organization is selected. If the
ORG pin is left unconnected, then an internal pullup
device will select the x16 organization.
