FM93C46A
1K-Bit Serial CMOS EEPROM
(MICROWIRE Synchronous Bus)
General Description
FM93C46A is a 1024-bit CMOS non-volatile EEPROM organized
as 64 x 16-bit array. This device features MICROWIRE interface
which is a 4-wire serial bus with chipselect (CS), clock (SK), data
input (DI) and data output (DO) signals. This interface is compat-
ible to many standard Microcontrollers and Microprocessors. This
device offers a pin (ORG), using which, the user can select the
format of the data (16-bit or 8-bit). If ORG is tied to GND, then 8-
bit format is selected, while if ORG is tied to V
CC
, then 16-bit format
is selected. There are 7 instructions implemented on the FM93C46A
for various Read, Write, Erase, and Write Enable/Disable opera-
tions. This device is fabricated using Fairchild Semiconductor
floating-gate CMOS process for high reliability, high endurance
and low power consumption.
“LZ” and “L” versions of FM93C46A offer very low standby current
making them suitable for low power applications. This device is
offered in both SO and TSSOP packages for small space consid-
erations.
