M95512-WMN6P

M95512-WMN6P is a 1‑Mbit serial EEPROM from STMicroelectronics with an SPI interface.
- Memory: 128 Kbytes (128K × 8), addressed with 24 bits (three address bytes).
- Interface/pins: SPI bus with CS, SCK, SI (MOSI), SO (MISO); plus WP, HOLD, VCC, GND in an 8‑pin package.
- Voltage/ temp: typically 2.7–5.5 V supply; operating temperature range (industrial variants available, e.g., -40 °C to 85 °C).
- Features: supports page write, write protection, and various read modes (including fast reads). Typical SPI clock up to about 40 MHz (conditions depend on supply/temperature).
- Endurance/retention: ~1,000,000 write cycles per byte; data retention on the order of decades.
- Use: non-volatile storage for configuration/calibration data in microcontrollers and embedded systems.
- Commands (illustrative): WREN (0x06) to enable writes; PAGE PROGRAM/WRITE (0x02) with 3‑byte address and up to a page of data; READ (0x03) with 3‑byte address; RDSR/WRSR for status; WP/HOLD pins for protection and low‑power hold.
- Packaging: 8‑pin plastic package; marked WMN6P.
