FEATURES
DESCRIPTION
The CAT93C46/56/57/66/86 are 1K/2K/2K/4K/16K-bit
Serial EEPROM memory devices which are configured
as either registers of 16 bits (ORG pin at V
(ORG pin at GND). Each register can be written (or read)
serially by using the DI (or DO) pin. The CAT93C46/56/
57/66/86 are manufactured using Catalyst’s advanced

PIN FUNCTIONS
PIN CONFIGURATION
DI
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.
