FM93C66LM8

Microwire串行EEPROM Microwire Serial EEPROM

General Description

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 compat ible 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 Semiconductor floating-gate CMOS process for high reliability, high endurance and low power consumption.
