PIN CONFIGURATION
DESCRIPTION
The CAT93C46R is a 1-Kb CMOS Serial EEPROM
device which is organized as either 64 registers of
16 bits or 128 registers of 8 bits, as determined by the
state of the ORG pin. The CAT93C46R features
sequential read and self-timed internal write with auto-
clear. On-chip Power-On Reset circuitry protects the
internal logic against powering up in the wrong state.
In contrast to the CAT93C46, the CAT93C46R features
an internal instruction clock counter which provides
improved noise immunity for Write/Erase commands.
FUNCTIONAL SYMBOL
Note: When the ORG pin is connected to V
CC
, 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 pull-up device
will select the x16 organization.
