M93C76-WMN6TP

The M93C76-WMN6TP is STMicroelectronics’ 8‑pin serial EEPROM in the M93C76 family. It provides non‑volatile storage for small data in microcontroller systems.
- Capacity: 8 kilobits (1024 × 8).
- Interface: Microwire-compatible serial interface (three wires: CS, SK, DI/DO).
- Voltage and speed: operates from 2.7 to 5.5 V; up to about 5 MHz clock.
- Performance: suitable for configuration and calibration data; uses a write‑enable sequence for writes.
- Endurance/retention: ~1,000,000 write cycles; data retention on the order of decades (≈40 years).
- Package: 8‑pin surface‑mount package; WMN6TP indicates the specific packaging/tape‑and‑reel options.
- Applications: small, non‑volatile memory for microcontrollers, automotive, consumer electronics.
For exact electrical specs, timing diagrams, and the full command set, consult the M93C76 datasheet.
