M24M01-DFDW6TP

M24M01-DFDW6TP is an STMicroelectronics 1-Mbit I2C serial EEPROM (M24M01 family). It provides non-volatile storage for small data like firmware config, calibration constants, or logs.
Key points:
- Capacity and organization: 1,048,576 bits ≈ 128 KB, addressed with 2-byte memory addresses.
- Interface: I2C two-wire bus (standard and fast modes; typical operation around 100–400 kHz; some variants up to higher speeds).
- Page and writes: 256-byte page write; one write cycle typically ~5 ms; endurance about 1,000,000 write cycles; data retention ~40 years.
- Power and temp: supply voltage ~1.7–5.5 V; temperature range depends on the grade (commercial to industrial).
- Package/variant: The -DFDW6TP suffix identifies a specific package, thermal rating, lead-free status, and tape-and-reel options.
Applications: microcontroller data/config storage, calibration tables, lookup data in embedded systems (consumer, industrial, automotive).
