Description

FM93C66A 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.  his interface is compatible to many of standard Microcontrollers and Microprocessors.FM93C66A 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 VCC, then 16-bit format is selected. There are 7 instructions implemented on the FM93C66A 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 FM93C66A offer very low standby current making them suitable for low power pplications. This device is offered in both SO and TSSOP packages for small space considerations.
