4096-bit Serial Cmos EEPROM

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 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 consid-erations.

Features:

• Wide VCC 2.7V - 5.5V
• Typical active current of 200µA
• No Erase instruction required before Write instruction
• Self timed write cycle
• Device status during programming cycles
• 40 year data retention
• Endurance: 1,000,000 data changes
• Packages available: 8-pin SO, 8-pin DIP, 8-pin TSSOP
