Product details
Overview
M24M02E-FCS6T/VF 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 lockable identification page. It serves as nonvolatile configuration storage in industrial sensors, automotive body controllers, and smart metering systems requiring secure parameter retention.
For engineers reviewing the M24M02E-FCS6T/VF datasheet, M24M02E-FCS6T/VF pinout, M24M02E-FCS6T/VF application, or M24M02E-FCS6T/VF equivalent, key selection considerations include configurable device address (CDA) register programmability, hardware write protection via WC pin, software write protection (SWP) register with irreversible lock bit (WPL), and ECOPACK2-compliant SO8N/TSSOP8/UFDFPN8/WLCSP5 packaging options.
Technical Context
The M24M02E-FCS6T/VF implements a dedicated I²C target interface with open-drain SDA and input 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 for EEPROM programming, ECC-enabled sense amplifiers, and dual-latch address decoding for reliable random/sequential read access.
Three user-accessible registers - Device Type Identifier (DTI), Configurable Device Address (CDA), and Software Write Protection (SWP) - are mapped into the I²C address space using distinct MSB address patterns (111, 110, 101). The identification page (256 bytes) resides at A15–A0 = 000xxxxx and supports permanent read-only locking independent of main array protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 2 Mbit (256 K × 8 bits) EEPROM with 256-byte identification page usable for secure calibration data storage |
| I²C speed modes | Supports 100 kHz (Standard), 400 kHz (Fast), and 1 MHz (Fast-mode Plus) - enables high-throughput firmware updates in real-time systems |
| Supply voltage | 1.6 V to 5.5 V operation - compatible with 1.8 V, 3.3 V, and 5 V logic domains without level shifters |
| Write endurance | 4 million write cycles - sufficient for daily logging over 10+ years in industrial monitoring applications |
| Data retention | 200-year retention at +85 °C - ensures long-term reliability in sealed automotive or energy infrastructure deployments |
| Standby current | 350 nA typical - minimizes battery drain in always-on IoT edge nodes and backup power circuits |
| Write time | Byte/page write ≤ 4 ms (typ. 3.3 ms) - enables deterministic timing control in time-critical boot configuration sequences |
Pinout & Package
Available in SO8N (150 mil), TSSOP8 (169 mil), UFDFPN8 (2 × 3 mm), and WLCSP5 (CS/CP variants); all ECOPACK2-compliant. Pin functions are identical across packages except for NC placement and WC pin orientation in WLCSP variants.
| 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 |
| SCL | Serial clock input | Master-generated clock strobe; device samples SDA on rising edge and asserts ACK during ninth cycle |
| WC | Hardware write control | Active-high global write disable: blocks all write operations including CDA/SWP/identification page writes when asserted |
| VCC | Supply voltage | 1.6–5.5 V power rail; requires local 10–100 nF decoupling capacitor near package pins |
| VSS | Ground reference | Return path for VCC; must be low-impedance connection to avoid noise-induced write corruption |
Key Features
| Feature | Design Value |
|---|---|
| Configurable device address (CDA) register | User-programmable C2 bit enables two unique I²C addresses per device; DAL bit allows irreversible lock to prevent field reconfiguration |
| Software write protection (SWP) register | BP0/BP1 define quarter/half/¾/full memory block protection; WPA enables/disables protection; WPL provides irreversible freeze |
| Identification page | 256-byte dedicated area with independent lock capability - stores factory-calibrated coefficients or security keys without affecting main array layout |
| Enhanced reliability | ESD > 4 kV HBM, latch-up immune per JESD78, and fast wake-up (< 5 μs) ensure robustness in noisy industrial environments |

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 1.7–5.5 V range, no WC pin, no identification page, no CDA/SWP registers | Lacks hardware write protection and configurable addressing - unsuitable for multi-device I²C buses or secure calibration storage | Select only if system uses single EEPROM per bus and requires no field-programmable address or permanent lock features |
| BR24M256FJ-WE2 | 2-Mbit I²C EEPROM with 1.6–5.5 V, built-in write protect pin (WP), but no SWP register or identification page | Provides basic hardware write disable but lacks software-configurable block protection or dedicated secure storage area | Choose when simple WP-based protection suffices and SWP register flexibility or identification page isolation is unnecessary |
Compared with AT24CM02-SSHD-T and BR24M256FJ-WE2, the M24M02E-FCS6T/VF uniquely combines hardware (WC), software (SWP), and physical (identification page lock) protection layers - enabling certified secure storage for industrial and medical applications where parameter integrity is auditable and enforceable.

FAQ
What is the function of the WC pin on the M24M02E-FCS6T/VF?
The WC (Write Control) pin is an active-high hardware enable that globally disables all write operations - including main array, identification page, CDA, and SWP register writes - when driven high. When low or floating, writes are permitted subject to software protection settings. This provides fail-safe protection against accidental overwrites during power transients or firmware errors.
Can the identification page be locked independently of the main memory array?
Yes. The 256-byte identification page supports independent permanent lock via a dedicated I²C command (device select code 1011 C2 011 RW). Once locked, all subsequent write attempts to this page return NO ACK. This isolation allows sensitive data like calibration constants or cryptographic keys to be secured without affecting main memory write policies.
How does the configurable device address (CDA) register affect I²C bus addressing?
The CDA register contains a single configurable bit (C2) that determines the chip-enable portion of the 7-bit I²C address. With C2 = 0 or 1, the device responds to addresses 0xA0/0xA1 (for memory access) or 0xB0/0xB1 (for register access), enabling up to two identical M24M02E-FCS6T/VF devices on the same I²C bus without address conflict.
What is the purpose of the Device Type Identifier (DTI) register?
The DTI register is a factory-programmed, permanently locked 8-bit read-only register containing device type identifier bits (1011) and lock status (DTIL = 1). It provides cryptographic assurance of authentic STMicroelectronics origin during boot-time verification and prevents counterfeit substitution in safety-critical systems.
