DESCRIPTION
The CAT93HC46 is a 1-kb Serial EEPROM memory
device which is configured as registers of either 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
SOIC Package (S, V)
FUNCTIONAL SYMBOL
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.
