概要
Description
M95512-WMN6P is a serial SPI EEPROM from STMicroelectronics (M95x family). It provides non‑volatile storage for embedded systems.
Key points:
- Interface: SPI (SCK, SI, SO, CS) with 3-byte addressing (A23…A0).
- Capacity: 1,048,576 bits = 128 KB. Page size typically 256 bytes; 512 pages total.
- Operations: Read and Write. Requires a Write Enable; typical write cycle ~5 ms. Endurance around 1,000,000 write cycles; data retention ~20 years.
- Power/ temp: Supply voltage usually in the 2.7–3.6 V range (some variants 2.7–5.5 V); operating temperature depending on grade (common is -40 to 85°C, with options up to -40 to 125°C).
- Packaging: 8-pin package (e.g., SO-8/TSSOP-8); WMN6P suffix denotes specific package/temperature/order options.
- Applications: Parameter/config storage, calibration tables, small logs, firmware/config data for microcontroller systems.
Note: Exact specs (voltage, temp range, timing) vary by package/revision; consult the M95512-WMN6P datasheet for precise details.
