M24M01-DFDW6TP

Introduction to M24M01-DFDW6TP
The M24M01-DFDW6TP is a STMicroelectronics 1-Mbit I2C serial EEPROM from the M24M01 family. It provides non-volatile storage for small data that must persist when power is removed.
Key points
- Capacity and organization: 1 Mbit (128 Kbytes) of memory, addressed with 16-bit addresses.
- Interface: I2C serial interface with a configurable slave address; supports random reads and page writes.
- Endurance and retention: typically around 1,000,000 write cycles with long data retention.
- Features: page write capability to improve throughput, write protection options, and low-power modes.
- Power and packaging: operates from a wide supply range and includes low-power sleep/standby; the DF DW6TP suffix denotes a specific package/packaging variant (Tape & Reel, etc.).
- Applications: suitable for microcontroller data storage, configuration/calibration data, device IDs, and logs.
- How to use: connect to an I2C bus, select the device address, write with a memory address pointer, and read back data. For exact electrical specs and timing, consult the M24M01 datasheet for this package variant.

Key features of M24M01-DFDW6TP (1-Mbit I2C serial EEPROM):
- Density: 1 Mbit (128 Kbytes) organized as 128K x 8
- Interface: I2C Two-wire serial interface; supports standard and fast modes
- Memory operations: Random and sequential read; 16-byte page write
- Write characteristics: Page write up to 16 bytes; typical write cycle ~5 ms
- Endurance/Data retention: Up to 1,000,000 write cycles; data retention ~100 years
- Voltage and temperature: Wide Vcc (typically 1.65–5.5 V); extended temperature range (-40°C to 125°C)
- Protection:WP pin for hardware write protection
- Package: 8-pin, RoHS-compliant, DFDW6TP (tape-and-reel)
Optional notes:
- Low-power operation with standby modes when not active
- Suitable for automotive/industrial and general embedded memory needs requiring nonvolatile storage with I2C ease of use.

M24M01-DFDW6TP uses an 8‑pin DFN (dual‑flat‑no‑leads) package, typically 3×3 mm. The “TP” suffix denotes Tape‑and‑Reel packaging.
