NM93C06LEN

Memory IC Overview

The NM93C06LEN is a 256-bit CMOS non-volatile EEPROM organized as a 16 x 16-bit array. It features a Microwire synchronous bus interface with Chip Select (CS), Serial Clock (SK), Data Input (DI), and Data Output (DO) signals. The device operates within a wide supply voltage range of 2.7V to 5.5V, supporting low power applications with typical standby currents of 1µA for the LZ variant. It includes seven instructions for read, write, erase, and control operations, utilizing self-timed write cycles.

Memory IC Feature Summary

• Microwire synchronous serial bus interface compatible with standard microcontrollers
• Self-timed write cycle with internal programming timer
• Data retention capability up to 40 years
• High endurance rated for one million data changes

Memory IC Applications

• Low power embedded systems requiring non-volatile storage
• Industrial control units needing parameter storage
• Consumer electronics with limited space constraints

Memory IC Procurement Notes

Verify the specific suffix 'LEN' against official manufacturer documentation, as datasheets primarily list 'N', 'M8', or 'MT8' package codes combined with temperature grades like 'E'. Confirm RoHS compliance status directly with the supplier, as older revisions may not meet current environmental standards. Ensure the source component matches the exact electrical characteristics defined in the latest revision.

Memory IC Selection Notes

Select this component when a small footprint serial EEPROM is required for storing configuration data or calibration values. The Microwire interface reduces pin count compared to SPI alternatives. Consider the extended voltage range if operating in environments with fluctuating power supplies. Verify that the 16-bit word size aligns with the application's data structure requirements.

Memory IC Part Context

This device belongs to the NM93C06 family of serial EEPROMs originally manufactured by Fairchild Semiconductor. The product line has transitioned through corporate acquisitions, with onsemi now managing the portfolio. These devices are widely used in legacy designs and industrial applications where robust, low-pin-count memory solutions are necessary.

Memory IC Replacement Considerations

Compatible substitutes include the FM93C06 series from onsemi and the CAT93C06 series. Verify pin compatibility and interface timing parameters before substitution. Ensure the replacement part supports the same Microwire protocol and voltage ranges.
