概要
Description
Introduction: M95320-WDW6TP is a serial non-volatile memory device in the M95x family, typically an I2C EEPROM used to store small data that must persist without power.
Key specs and features:
- Capacity: 32 kbit (4 KB) memory organized as 4K x 8
- Interface: I2C (2-wire); supports standard and fast I2C modes
- Supply: typically 2.7–5.5 V
- Package: 8-pin device
- Operations: byte and page writes (up to a page size, e.g., 32 bytes), random/read access
- Power: low-power standby; write time around a few milliseconds
- Endurance and protection: hardware write-protect and basic write-cycle management
Typical applications:
- Storing configuration data, calibration constants, device IDs, and small logs for embedded systems
Usage notes:
- Use the I2C address available with A0–A2 pins; respect page boundaries during page writes
- For exact timing, voltage, and environmental specs, consult the official datasheet from the manufacturer. If you share the maker, I can tailor the summary precisely.
