DESCRIPTION
The CAT93HC46 is a 1K-bit Serial EEPROM memory
devices which is configured as either registers of 16 bits
(ORG pin at VCC) or 8 bits (ORG pin at GND). Each
register can be written (or read) serially by using the DI
(or DO) pin. The CAT93HC46 is manufactured using
Catalyst’s advanced CMOS EEPROM floating gate
technology. The device is designed to endure 1,000,000
program/erase cycles and has a data retention of 100
years. The CAT93HC46 is available in 8-pin DIP, 8-pin
SOIC or 8-pin TSSOP packages.

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 pullup device will select the X16
organization.
