FM93C86A Rev. C.1
FM93C86A is a 16,384-bit CMOS non-volatile EEPROM orga-
nized as 1024 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 compatible to many of standard Microcontrollers and Micropro-
cessors. 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
bit format is selected. There are 7 instructions implemented on the
FM93C86A for various Read, Write, Erase, and Write Enable/
Disable operations. 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 FM93C86A offer very low standby current
making them suitable for low power applications. This device is
offered in both SO and DIP packages.
