93C66 Datasheet – 4096-Bit Serial CMOS EEPROM

The 93C66 is a 4096-Bit Serial CMOS EEPROM (MICROWIRE Synchronous Bus) made by Fairchild Semiconductor, supplied in these packages: 8-pin SO, 8-pin DIP, 8-pin TSSOP Type. The absolute maximum ratings table on this page lists the 4 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the 93C66 pinout and maximum ratings, with the full datasheet PDF to preview below or download.

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.

“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.
