FM93C56LZEMT8

Memory IC Overview

The FM93C56LZEMT8 is a 2048-bit CMOS non-volatile EEPROM organized as a 128 x 16-bit array. It features a MICROWIRE synchronous bus interface with chipselect (CS), clock (SK), data input (DI), and data output (DO) signals, compatible with standard microcontrollers. Fabricated using Fairchild Semiconductor's floating-gate CMOS process, it offers high reliability and low power consumption. The device supports read, write, erase, and write enable/disable operations via seven instructions. It provides 40-year data retention and endurance of one million write/erase cycles.

Memory IC Feature Summary

• MICROWIRE 4-wire serial bus interface for standard microcontroller compatibility
• Floating-gate CMOS fabrication ensuring high reliability and endurance
• Self-timed write cycle without requiring prior erase instruction
• Low standby current characteristics in LZ versions

Memory IC Applications

• Data storage in systems requiring non-volatile memory
• Configuration storage for microcontroller-based devices
• Parameter storage in industrial control applications

Memory IC Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to confirm package type and temperature range specifications. Ensure the ordering part number matches the required voltage and interface standards. Confirm availability status directly with authorized distributors or the manufacturer, as supply conditions may vary.

Memory IC Selection Notes

Select this component when a 128-word by 16-bit capacity is required with MICROWIRE interface compatibility. Consider the LZ suffix variant if ultra-low standby current is critical for the application. Verify that the operating voltage range aligns with the system power supply requirements before integration.

Memory IC Part Context

This device belongs to the NM93C56/FM93C56 family of serial CMOS EEPROMs from Fairchild Semiconductor. It shares functional similarities with other members like the NM93C56LEMT8 but may differ in specific package options or electrical characteristics defined by the suffix codes. It is designed for space-constrained applications requiring reliable non-volatile storage.
