M24C16-WDW6TP

M24C16-WDW6TP is STMicroelectronics’ 16‑Kbit (2048 bytes) I2C serial EEPROM, part of the M24Cxx family.
Key points:
- Interface: I2C two‑wire (SCL, SDA); supports standard 100 kbps and fast mode 400 kbps.
- Memory: 2048 × 8 bits; memory addressed via a word address plus device address bits.
- Access: random and sequential read; page write support (typical page size around 16 bytes).
- Write cycle: ~5 ms typical; writes require polling or busy flag to complete.
- Endurance/retention: about 1,000,000 write cycles; data retention ~10–40 years (dependent on grade).
- Voltage and temp: wide operating voltage (commonly 1.7–5.5 V); wide/industrial temperature variants available.
- Package: 8-pin package (e.g., SO-8/SOP-8); “WDW6TP” suffix denotes specific packaging/temperature/ordering options.
Typical uses: non-volatile storage for microcontroller data, calibration constants, configuration data, and small data logs in embedded systems.
Note: For exact electrical specs, timing, addressing scheme, and the precise meaning of WDW6TP, consult the latest M24C16 datasheet and the ST packaging/ordering table.
