Product details
Overview
M24M01E-FDW6TP from STMicroelectronics is a 1-Mbit I²C-compatible EEPROM organized as 128 K × 8 bits, operating from 1.6 V to 5.5 V with support for 1 MHz Fast-mode Plus, 400 kHz Fast-mode, and 100 kHz Standard-mode I²C bus speeds. It features configurable device address (CDA), software write protection (SWP), and a 256-byte identification page permanently lockable in read-only mode - deployed in industrial control modules for firmware parameter storage and calibration data retention.
For engineers reviewing the M24M01E-FDW6TP datasheet, M24M01E-FDW6TP pinout, M24M01E-FDW6TP application, or M24M01E-FDW6TP equivalent, key selection criteria include its 4 ms typical byte/page write time, 350 nA standby current, hardware write control (WC) input, preprogrammed device address capability, and ECOPACK2-compliant SO8N/TSSOP8/UFDFPN8/WLCSP5 packaging options.
Technical Context
The M24M01E-FDW6TP implements a full I²C target interface with open-drain SDA and input SCL, supporting standard, fast, and fast-plus timing modes. Its internal architecture includes dedicated registers - device type identifier (DTI), configurable device address (CDA), and software write protection (SWP) - all accessible via distinct I²C command sequences using device-type-identifier-based addressing (1011).
Memory access uses 17-bit addressing: A16 embedded in the device select code, A15–A8 in the first address byte, and A7–A0 in the second. The WC pin provides hardware-level write disable for the entire memory array when driven high, independent of SWP register state or I²C command execution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 1 Mbit (128 K × 8), enabling storage of large configuration sets or firmware metadata in space-constrained designs. |
| I²C speed support | Up to 1 MHz (Fast-mode Plus), allowing high-throughput parameter updates without bus contention in multi-device systems. |
| Write cycle time | ≤4 ms (typ. 3 ms) for byte and page writes, minimizing system latency during nonvolatile data commits. |
| Supply voltage range | 1.6 V to 5.5 V, supporting direct integration with 1.8 V, 3.3 V, and 5 V logic domains without level-shifting. |
| Data retention | 200+ years, ensuring long-term reliability for calibration constants and security keys in unattended equipment. |
| Write endurance | 4 million cycles, suitable for frequent logging or dynamic parameter tuning in industrial HMI and sensor nodes. |
| Standby current | 350 nA (typ.), critical for battery-powered IoT edge devices requiring ultra-low quiescent power. |
Pinout & Package
Available in SO8N (150 mil), TSSOP8 (169 mil), UFDFPN8 (2 × 3 mm), and WLCSP5 (5-ball) packages - all ECOPACK2 compliant. Pin functions are identical across packages except for NC placements and ball/pad mapping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SDA | Serial Data I/O | Open-drain bidirectional bus line; requires external pull-up; supports wired-AND with other I²C devices. |
| SCL | Serial Clock Input | Master-generated clock synchronizing all data transfers; defines timing compliance for 100/400/1000 kHz modes. |
| WC | Hardware Write Control | Active-high global write disable: blocks all write operations regardless of SWP register or address range. |
| VCC | Supply Voltage | 1.6–5.5 V DC input; decoupling capacitor (10–100 nF) required near pins to suppress switching noise. |
| VSS | Ground Reference | Return path for VCC; must be low-impedance and co-located with decoupling cap to ensure stable POR behavior. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable device address (CDA) register | Two user-programmable bits (C2/C1) enable up to four unique I²C addresses on one bus, eliminating address conflicts in multi-EEPROM systems. |
| Software write protection (SWP) register | Four-bit nonvolatile control (WPA, BP1/BP0, WPL) allows selective block-level write protection - e.g., locking upper 75% of memory while leaving lower sector writable. |
| Identification page | 256-byte dedicated area for storing calibration coefficients or serial numbers, lockable permanently in read-only mode to prevent tampering. |
| Preprogrammed device address option | Factory-set C2/C1 and locked DAL bit eliminate field programming steps - simplifies BOM management and reduces firmware initialization complexity. |
| Enhanced reliability | 4 million write cycles and 200-year data retention meet industrial lifetime requirements for programmable logic controllers and medical diagnostics equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24CM01-SSHD-T (Microchip) | Same 1 Mbit density and I²C interface, but lacks WC pin and identification page; supports only 100/400 kHz modes (no 1 MHz). | No hardware write disable or dedicated calibration storage - unsuitable where ESD-immune write blocking or certified calibration data isolation is required. | Select when cost sensitivity outweighs need for WC pin or identification page; verify timing margins for 400 kHz-only systems. |
| BR24M10YFVM-WE2 (ROHM) | Includes WC pin and 1 Mbit capacity, but no configurable device address register or DTI/CDA/SWP register set; max 400 kHz I²C speed. | Lacks per-device address customization and fine-grained software protection - limits scalability in dense I²C networks with >4 EEPROMs. | Choose for simpler designs needing basic hardware write protection only; avoid where multi-device address management or field-programmable protection is needed. |
Compared with AT24CM01-SSHD-T and BR24M10YFVM-WE2, the M24M01E-FDW6TP uniquely combines 1 MHz I²C, WC pin, CDA register, SWP register, and lockable identification page - making it the only option supporting both high-speed parameter updates and certified calibration data segregation in a single package.

FAQ
What is the function of the WC pin on the M24M01E-FDW6TP?
The WC (Write Control) pin is an active-high hardware input that globally disables all write operations to the entire memory array, regardless of software write protection settings or I²C command validity. When driven high, the device acknowledges device select and address bytes but rejects data bytes with a NACK, preventing inadvertent writes during power transients or system resets.
Can the identification page be rewritten after being locked?
No. Once the identification page is locked (via dedicated I²C command), it becomes permanently read-only: subsequent write attempts to that 256-byte region result in NACK on the data byte, and no data is stored. The lock is irreversible and enforced by internal fuse-like logic - verified by reading back the lock status bit in the DTI register.
How does the configurable device address (CDA) register interact with I²C addressing?
The CDA register holds two user-defined bits (C2/C1) that form part of the I²C device select code. During communication, the controller sends a 7-bit address where bits b3–b2 must match C2/C1 for the device to ACK. This allows up to four unique addresses on one bus; the DAL bit freezes C2/C1 permanently once set to 1, preventing runtime reconfiguration.
Is the M24M01E-FDW6TP compatible with 1.8 V microcontrollers?
Yes. Its 1.6 V to 5.5 V supply range includes 1.8 V operation, and its I²C interface meets standard-mode and fast-mode electrical specifications at that voltage. SDA and SCL inputs are TTL-compatible down to 0.3×VCC, and the 350 nA standby current ensures minimal loading on 1.8 V power rails in battery-critical applications.
