NM93C66MT8X

Memory IC Overview

The NM93C66MT8X is a 4096-bit CMOS non-volatile EEPROM organized as a 256 x 16-bit array. It features a MICROWIRE synchronous bus interface with chip select (CS), clock (SK), data input (DI), and data output (DO) signals. The device supports read, write, erase, and write enable/disable operations via seven implemented instructions. Fabricated using a floating-gate CMOS process, it offers high reliability and endurance. The component is housed in an 8-pin plastic surface-mount package.

Memory IC Feature Summary

• Supports MICROWIRE four-wire serial bus interface compatible with standard microcontrollers
• Provides non-volatile memory storage with high endurance capabilities
• Enables flexible data management through multiple instruction sets for read, write, and erase operations

Memory IC Applications

• Data storage in systems utilizing standard microcontrollers
• Configuration parameter retention in embedded devices
• Calibration data storage for industrial control applications

Memory IC Procurement Notes

Verify the specific suffix MT8X against official Fairchild documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with existing MICROWIRE protocol implementations in the target system design before procurement.

Memory IC Selection Notes

Select this component when a 256-word by 16-bit memory depth is required within a compact surface-mount footprint. Consider the MICROWIRE interface requirements and ensure the host controller supports the necessary four-wire synchronous communication protocol for reliable data exchange.

Memory IC Part Context

This part belongs to the NM93C66 series of serial EEPROMs manufactured by Fairchild Semiconductor. It shares architectural similarities with other members of the family, differing primarily in memory organization and packaging options. The series is designed for low-power, high-reliability non-volatile storage applications.

Memory IC Replacement Considerations

Compatible substitutes include FM93C66AEMT8X from Rochester Electronics or Fairchild. Verify pinout compatibility and electrical characteristics against the original datasheet before substitution.
