概述

Description

The M93C76-WMN6TP is an 8‑kilobit serial EEPROM with a Microwire-compatible interface. It provides non-volatile storage for embedded systems and is typically organized as 512 words × 16 bits (8,192 bits total).
Key features:
- Interface: three-wire (Chip Select CS, Serial Clock SK, Data I/O DI/DO)
- Operation: READ and WRITE commands with a software write-protect mechanism (EWEN to enable writes, EWDS to disable)
- Supply: generally 2.7 V to 5.5 V
- Package: WMN6TP suffix indicates an 8-pin SMT package variant
Typical uses:
- Storing configuration or calibration data, device IDs, and small parameter sets
How to use (brief):
- Read: assert CS, send READ opcode with address, clock, and read data from DO
- Write: enable writes (EWEN), issue WRITE to the address, complete the required write cycle, then optionally disable writes (EWDS)
For exact timing, addressing, endurance, and voltage specifics, consult the M93C76-WMN6TP datasheet.

Package

An 8-pin plastic SOIC (SOP-8) surface-mount package, Tape‑and‑Reel (TP) packaging.

Pinout
