FM93C66
4096-Bit Serial CMOS EEPROM
(MICROWIRE™ Synchronous Bus)
General Description
Features
FM93C66 is a 4096-bit CMOS non-volatile EEPROM organized
as 256 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 Microprocessors.
There are 7 instructions implemented on the FM93C66 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.
■ Wide VCC 2.7V - 5.5V
“LZ” and “L” versions of FM93C66 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 considerations.
■ Endurance: 1,000,000 data changes
■ Typical active current of 200µA
10µA standby current typical
1µA standby current typical (L)
0.1µA standby current typical (LZ)
■ No Erase instruction required before Write instruction
■ Self timed write cycle
■ Device status during programming cycles
■ 40 year data retention
■ Packages available: 8-pin SO, 8-pin DIP, 8-pin TSSOP

NOTE: Pins designated as "NC" are typically unbonded pins. However some of them are bonded for special testing purposes. Hence if a signal is applied to these pins, care
should be taken that the voltage applied on these pins does not exceed the VCC applied to the device. This will ensure proper operation.
