Product details
Overview
M24M01E-FMN6TP from STMicroelectronics is a 1-Mbit (128-Kbyte) 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 buses. It features configurable device address (CDA), software write protection (SWP), and a dedicated 256-byte identification page for secure parameter storage in industrial control modules.
For engineers reviewing the M24M01E-FMN6TP datasheet, M24M01E-FMN6TP pinout, M24M01E-FMN6TP application, or M24M01E-FMN6TP equivalent, key selection criteria include its 4 ms typical byte/page write time, 350 nA standby current, hardware write protection via WC pin, preprogrammed device address capability, and ECOPACK2-compliant SO8N/TSSOP8/UFDFPN8/WLCSP5 packaging options.
Technical Context
The M24M01E-FMN6TP implements a full I²C target protocol with start/stop detection, ACK/NACK handling, and 17-bit memory addressing (A16 embedded in device select code). Its internal architecture includes an HV generator, ECC-enabled sense amplifier, and page latches supporting 256-byte page writes.
Three dedicated 8-bit registers-Device Type Identifier (DTI), Configurable Device Address (CDA), and Software Write Protection (SWP)-are accessed via distinct I²C command sequences using device-type identifier 1011 and specific MSB address patterns (111, 110, 101). The identification page supports permanent read-only locking after programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 1 Mbit (128 K × 8 bits), enabling firmware parameter storage for mid-tier microcontrollers without external memory expansion. |
| I²C speed modes | Supports 1 MHz (Fast-mode Plus), 400 kHz (Fast-mode), and 100 kHz (Standard-mode); enables interoperability across legacy and high-speed I²C systems. |
| Supply voltage range | 1.6 V to 5.5 V - allows direct interface with 1.8 V, 3.3 V, and 5 V logic domains without level shifters. |
| Write cycle time | ≤4 ms (typ. 3 ms) for byte and page writes - reduces firmware update latency in real-time configuration updates. |
| Data retention | 200+ years - ensures long-term reliability for calibration data and security keys in unattended equipment. |
| Write endurance | 4 million cycles - supports frequent logging or counter applications in metering and diagnostics. |
| Standby current | 350 nA (typ.) - minimizes battery drain in always-on IoT edge nodes and portable instrumentation. |
Pinout & Package
Package: SO8N (150 mil width), RoHS-compliant and ECOPACK2 certified. Pin mapping validated per DS13858 Rev 4 Figure 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SDA | Serial Data I/O | Open-drain bidirectional bus line requiring external pull-up; supports wired-AND with other I²C devices on same bus segment. |
| SCL | Serial Clock Input | Master-generated clock signal synchronizing all data transfers; must remain stable during SDA transitions. |
| WC | Hardware Write Control | Active-high global write lock: disables all memory writes when high, including register and identification page access. |
| VCC | Supply Voltage | 1.6–5.5 V power input; requires local 10–100 nF decoupling capacitor near package pins for noise immunity. |
| VSS | Ground Reference | Return path for VCC; must be low-impedance connection to avoid ground bounce during write cycles. |
| NC (pins 5–7) | No Connect | Unbonded die pads; must remain floating or grounded per PCB layout guidelines to prevent parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Device Address Register (CDA) | 8-bit register with C2/C1 bits enabling up to four unique I²C addresses on one bus; DAL bit provides irreversible lock after configuration. |
| Software Write Protection (SWP) | Nonvolatile 4-bit register (WPA, BP1, BP0, WPL) allowing selective block protection (¼ to full memory) and permanent lock against accidental reconfiguration. |
| Identification Page | 256-byte dedicated page for storing calibration coefficients or security keys, with option to permanently lock as read-only post-programming. |
| Enhanced Reliability | 4 million write cycles and 200-year data retention verified under -40°C to +85°C operation - suitable for automotive body electronics and industrial PLCs. |
| Ultra-low Power Wake-up | <5 µs wake-up time from standby - enables rapid response to host controller commands in energy-constrained sensor nodes. |

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) | 1 Mbit I²C EEPROM; supports 1 MHz but lacks identification page and DTI/CDA/SWP registers; only hardware WP pin (no software protection). | Requires external logic for multi-device addressing; no secure parameter storage capability. | Select when register-level configurability and identification page are unnecessary and cost sensitivity dominates. |
| BR24M10YFVM-WE2 (ROHM) | 1 Mbit I²C EEPROM; includes software write protection and 256-byte ID page, but no configurable device address register or preprogrammed address option. | Limited I²C bus scalability due to fixed 7-bit address; no CDA-based multi-drop flexibility. | Choose when identification page and SWP suffice, and board space constraints favor smaller TSSOP8 footprint. |
Compared with AT24CM01-SSHD-T and BR24M10YFVM-WE2, the M24M01E-FMN6TP uniquely integrates configurable addressing, three dedicated registers (DTI/CDA/SWP), and preprogrammed address variants - enabling scalable, secure, and field-upgradable configurations in multi-node industrial systems.

FAQ
What is the function of the WC pin on M24M01E-FMN6TP?
The WC (Write Control) pin is an active-high hardware enable that globally disables all write operations-including memory array, identification page, and register writes-when driven high. When low or floating, writes are permitted subject to software write protection settings. This provides fail-safe protection against spurious writes during power transients.
Can the identification page be locked permanently after programming?
Yes. After writing data to the 256-byte identification page, issuing the identification page lock command permanently sets it to read-only mode. Subsequent write attempts to this page result in NO ACK, and the lock cannot be reversed. This ensures calibration or security data remains immutable throughout the device's operational life.
How does the configurable device address (CDA) register work?
The CDA register uses bits C2/C1 to define a 2-bit chip-enable address within the I²C device select code, allowing up to four unique addresses on one bus. The DAL bit irreversibly locks the register once set to 1, preventing runtime reconfiguration. Factory-default CDA is 00, but preprogrammed variants (e.g., M24M01E-Fxx6T1) ship with C2=0/C1=1 and DAL=1.
Is M24M01E-FMN6TP compatible with 1.8 V I²C systems?
Yes. With a minimum operating voltage of 1.6 V and full I²C timing compliance down to that level, the M24M01E-FMN6TP operates reliably in 1.8 V systems. Its 350 nA standby current and <5 µs wake-up time make it especially suitable for battery-powered 1.8 V sensor nodes where power efficiency is critical.
