Product details
Overview
M24C04-DRMF3TG/K from STMicroelectronics is an AEC-Q100 Grade 1 automotive serial EEPROM with 4 Kbits (512 bytes) of I²C-compatible memory, 1 MHz max clock rate, and operation from -40 °C to 125 °C at 1.7–5.5 V. It features a 16-byte page size, an additional lockable 16-byte identification page, and embedded ECC for single-bit error correction - deployed in engine control units for calibration data storage.
For engineers reviewing the M24C04-DRMF3TG/K datasheet, M24C04-DRMF3TG/K pinout, M24C04-DRMF3TG/K application, or M24C04-DRMF3TG/K equivalent, key selection criteria include automotive temperature compliance (-40 °C to 125 °C), write endurance at elevated temperature (600 k cycles at 125 °C), identification page locking capability, and I²C bus timing compatibility up to 1 MHz.
Technical Context
The M24C04-DRMF3TG/K implements a true EEPROM array organized as 32 pages × 16 bytes, with dedicated logic for ECC-based single-bit error correction on every read. Its I²C interface supports standard (100 kHz), fast (400 kHz), and fast-plus (1 MHz) modes, with Schmitt-triggered SCL/SDA inputs for robust noise immunity in automotive environments.
Chip enable (E1/E2) pins configure the 2-bit portion of the 7-bit device address, enabling up to four devices on one bus. The write control (WC) input provides hardware-level protection: high = full memory write disable; low or floating = write enabled. The identification page (16 bytes) supports permanent lock to read-only after programming.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C04C-SSHM-T | 4-Kbit I²C EEPROM, AEC-Q100 Grade 2 (-40 °C to 105 °C), no identification page or ECC | Limited to under-dash modules; unsuitable for under-hood use above 105 °C | Select only if Grade 2 temp range suffices and ECC/ID page are unnecessary |
| BR24G04NUX-10 | 4-Kbit I²C EEPROM, AEC-Q100 Grade 1, 1.7–5.5 V, but no identification page lock or ECC | Supports same temperature range but lacks hardware-locked ID page for secure parameter binding | Choose when cost sensitivity outweighs need for locked calibration data protection |
Compared with AT24C04C-SSHM-T and BR24G04NUX-10, the M24C04-DRMF3TG/K uniquely combines Grade 1 temperature rating, embedded ECC, and a permanently lockable identification page - making it the only option for safety-critical, thermally demanding automotive calibration storage where data integrity and tamper resistance are mandatory.

FAQ
What is the function of the WC pin on the M24C04-DRMF3TG/K?
The WC (Write Control) pin is a hardware-level write protection input. When driven high, it disables all write operations to the entire memory array-including byte, page, and identification page writes-while still allowing read access and device addressing. This prevents accidental overwrites during power transitions or firmware glitches. WC can be left floating (default low) or pulled low to enable writes.
How does the identification page differ from the main memory array?
The identification page is a dedicated 16-byte region separate from the main 512-byte EEPROM array. It contains factory-programmed ST device identification codes (bytes 0–2) and space for application-specific parameters (bytes 3–15). Unlike main memory, it supports a permanent lock-to-read-only command that cannot be reversed, ensuring calibration or security data remains immutable after programming.
Does the M24C04-DRMF3TG/K support I²C clock stretching?
No, the M24C04-DRMF3TG/K does not implement clock stretching. It relies on fixed internal write cycle timing (≤4 ms) and uses ACK polling-where the host repeatedly sends start + device address until an ACK is received-to detect write completion. This simplifies bus arbitration and avoids timing conflicts in multi-master I²C systems.
What is the role of ECC in this EEPROM, and how is it implemented?
The M24C04-DRMF3TG/K integrates transparent ECC x 1 logic that automatically detects and corrects any single-bit error during memory reads. It operates per-byte without software intervention or additional overhead, using dedicated on-die logic. This significantly improves long-term data reliability in automotive environments where radiation-induced soft errors or wear-related bit flips may occur.
