Product details
Overview
M24M02E-FMC6TG from STMicroelectronics is a 2-Mbit I²C-compatible EEPROM organized as 256 K × 8 bits, operating from 1.6 V to 5.5 V with 1 MHz Fast-mode Plus support, -40 °C to +85 °C temperature range, and 256-byte page write capability. It integrates configurable device address (CDA), software write protection (SWP), and a lockable 256-byte identification page for secure parameter storage in industrial control modules.
For engineers reviewing the M24M02E-FMC6TG datasheet, M24M02E-FMC6TG pinout, M24M02E-FMC6TG application, or M24M02E-FMC6TG equivalent, key selection criteria include I²C bus timing compliance (1 MHz), hardware/software write protection granularity, identification page lockability, and ECOPACK2-compliant WLCSP5/UFDFPN8/SO8N/TSSOP8 package options for space-constrained embedded systems.
Technical Context
The M24M02E-FMC6TG implements a dedicated I²C target interface with open-drain SDA and input-only SCL, supporting Standard-mode (100 kHz), Fast-mode (400 kHz), and Fast-mode Plus (1 MHz) clock rates. Its internal architecture includes an HV generator, ECC-enabled sense amplifier, and page latches enabling 256-byte page writes within 4 ms.
Three nonvolatile configuration registers - Device Type Identifier (DTI), Configurable Device Address (CDA), and Software Write Protection (SWP) - are accessed via dedicated I²C sub-addressing protocols using distinct MSB address patterns (111, 110, 101). The WC pin provides hardware-level memory array write disable independent of register settings.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24CM02-SSHD-T | 2 Mbit I²C EEPROM with 1 MHz support but no identification page or CDA register; only hardware WP pin | Lacks configurable addressing and lockable ID page - unsuitable for multi-device I²C networks requiring secure parameter storage | Select when cost sensitivity outweighs need for advanced protection features and device address flexibility |
| BR24M02FJ-WE2 | 2 Mbit I²C EEPROM with 1 MHz support, software write protection, but no WC pin or identification page lock capability | Missing hardware write disable (WC) and permanent ID page lock - insufficient for safety-critical or anti-tamper use cases | Choose for general-purpose logging where full memory protection hierarchy is not required |

FAQ
What is the function of the WC pin on the M24M02E-FMC6TG?
The WC (Write Control) pin is an active-high hardware disable for all memory write operations. When driven high, it blocks byte/page writes, identification page programming, and SWP register updates - regardless of software protection state or I²C command. This provides fail-safe protection against unintended writes during power transients or firmware errors.
How does the identification page differ from main memory in the M24M02E-FMC6TG?
The identification page is a dedicated 256-byte region accessible via unique I²C sub-addressing (MSB = 000). Unlike main memory, it supports permanent lock-to-read-only mode via a one-time fuse-like operation. Once locked, write attempts return NACK - making it suitable for storing immutable calibration data, cryptographic keys, or regulatory identifiers that must survive field updates.
Can the configurable device address (CDA) be changed after delivery?
Yes, if the DAL (Device Address Lock) bit is 0, the C2 bit in the CDA register can be rewritten via I²C command. However, setting DAL=1 permanently freezes the register. For M24M02E-FMC6TG, the part number suffix "MC6TG" indicates the WLCSP5-CP package with factory-default CDA (C2=0, DAL=0), allowing field reconfiguration unless explicitly locked by the user.
What I²C clock frequency should be used for reliable operation at 1.8 V supply?
At 1.8 V supply, the M24M02E-FMC6TG supports up to 400 kHz (Fast-mode) reliably. While rated for 1 MHz (Fast-mode Plus), the 1.8 V condition falls below the minimum VCC requirement for 1 MHz operation per DS14157 Rev 4 Section 9.1 - using 400 kHz ensures proper setup/hold timing margins and avoids ACK failures during high-speed transfers.
