PIN CONFIGURATION

DIP Package (P, L)

SOIC Package (J, W)

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.
