Product details
Overview
M24C04-DRMN3TP/K from STMicroelectronics is an AEC-Q100 Grade 1 automotive serial EEPROM with 4 Kbits (512 × 8) memory, I²C interface supporting up to 1 MHz, 16-byte page size, and extended operation from −40 °C to 125 °C at 1.7 V–5.5 V. It integrates ECC for single-bit error correction and includes a write-lockable 16-byte identification page used for device ID storage and application parameter retention in vehicle control modules.
For engineers reviewing the M24C04-DRMN3TP/K datasheet, M24C04-DRMN3TP/K pinout, M24C04-DRMN3TP/K application, or M24C04-DRMN3TP/K equivalent, key selection criteria include automotive temperature compliance, I²C clock speed support (1 MHz), byte/page write timing (≤4 ms), write endurance at 125 °C (600 k cycles), and identification page lockability for secure parameter storage.
Technical Context
The M24C04-DRMN3TP/K implements a true EEPROM array organized into 32 pages of 16 bytes each, with embedded ECC logic correcting single-bit errors during read operations. Its I²C interface complies fully with standard, fast, and high-speed modes (100 kHz/400 kHz/1 MHz), using open-drain SDA with external pull-up and Schmitt-triggered SCL/E1/E2/WC inputs for robust noise immunity.
Chip enable (E1, E2) pins configure the 2-bit address portion of the 7-bit I²C device select code (1010b for memory, 1011b for ID page), enabling up to four devices on one bus. The WC pin provides hardware-level write protection: high = full memory write inhibit; low or floating = write enabled - including to the 16-byte identification page, which supports permanent lock via dedicated instruction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4 Kbits (512 bytes), organized as 32 × 16-byte pages - enables efficient firmware parameter storage with page-aligned writes. |
| I²C clock frequency | Up to 1 MHz - supports high-throughput configuration updates in real-time automotive subsystems like body control modules. |
| Write cycle time | ≤4 ms for byte or page write - minimizes bus occupancy and enables deterministic timing in safety-critical boot sequences. |
| Endurance @ 125 °C | 600 k write cycles - ensures reliable calibration data logging over full vehicle lifetime under hood-high-temp conditions. |
| Data retention @ 125 °C | 50 years - guarantees persistent storage of VIN, calibration IDs, and security keys without refresh in engine control units. |
| Supply voltage range | 1.7 V to 5.5 V - interoperates across 3.3 V and 5 V automotive domains without level-shifting circuitry. |

Pinout & Package
Package: SO8N (MN), 150 mil width, RoHS-compliant and halogen-free (ECOPACK2®).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SDA | Serial Data I/O | Open-drain bidirectional bus line - requires external pull-up; supports wire-OR with other I²C devices. |
| 2: VSS | Ground | Reference return path for VCC and all logic signals - must be low-impedance for stable ECC and write timing. |
| 3: SCL | Serial Clock Input | Schmitt-triggered clock input - rejects noise spikes and ensures clean edge sampling up to 1 MHz. |
| 4: WC | Write Control | Hardware write lock: high = full memory write disabled; low/floating = write enabled - critical for preventing corruption during power transients. |
| 5: E1 | Chip Enable Bit 1 | Configures bit b2 of I²C device address (1010b/1011b) - tied high/low to assign unique bus address among up to four devices. |
| 6: NC | No Connect | Internally unused pin - must remain unconnected per datasheet; no routing or grounding allowed. |
| 7: VCC | Supply Voltage | Power input (1.7–5.5 V) - requires local 10–100 nF decoupling capacitor to maintain voltage stability during internal write cycles. |
| 8: E2 | Chip Enable Bit 2 | Configures bit b3 of I²C device address - used with E1 to select one of four possible addresses on shared I²C bus. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C04C-SSHM-T (Microchip) | Same 4-Kbit capacity, AEC-Q100 Grade 2 (−40 °C to 105 °C), no identification page or ECC. | Lacks ID page lock and ECC - unsuitable for ASIL-B systems requiring fault-tolerant reads. | Select only for non-safety-critical cabin modules where 105 °C max temp suffices. |
| BR24G04NUX-3GE2 (ROHM) | AEC-Q100 Grade 1, 1 MHz I²C, but no dedicated ID page; uses software write-protect instead of WC pin. | Requires firmware coordination for write protection - increases risk of corruption during interrupt latency or reset. | Prefer when pin count is constrained and hardware lock is not required for system architecture. |
Compared with AT24C04C-SSHM-T and BR24G04NUX-3GE2, the M24C04-DRMN3TP/K uniquely combines Grade 1 temperature rating, hardware WC pin lock, factory-programmed ID page, and ECC - making it the only choice for ASIL-B-compliant storage of calibration and security data in powertrain and ADAS ECUs.

FAQ
What is the function of the WC pin on the M24C04-DRMN3TP/K?
The WC (Write Control) pin is a hardware-level write protection input. When driven high, it disables all write operations to both the main memory array and the identification page - preventing accidental or malicious modification during power transients, resets, or firmware updates. When low or left floating, writes are enabled. This behavior is implemented entirely in silicon and requires no software overhead.
How does the identification page differ from the main memory array?
The identification page is a separate 16-byte region accessible via I²C device type identifier 1011b (vs. 1010b for main memory). It contains three factory-programmed bytes (ST manufacturer code 20h, I²C family code E0h, density code 09h) followed by 13 user-writable bytes. Once locked via the dedicated "lock ID" instruction, the entire page becomes permanently read-only - unlike main memory, which supports standard byte/page writes without lock capability.
Does the M24C04-DRMN3TP/K support standard I²C addressing with multiple devices on one bus?
Yes - the E1 and E2 pins configure bits b2 and b3 of the 7-bit I²C device address, allowing up to four M24C04-DRMN3TP/K devices to share a single I²C bus. Each device responds only when its E1/E2 combination matches the corresponding bits in the transmitted device select code (1010b for memory, 1011b for ID page), enabling scalable parameter storage across distributed automotive ECUs without address conflicts.
What is the role of ECC in this EEPROM, and how is it implemented?
The M24C04-DRMN3TP/K includes embedded single-bit error correction code (ECC x1) logic applied transparently to every 8-bit memory word. During read operations, if one bit flips due to radiation or aging, ECC detects and corrects it in real time - returning valid data without CPU intervention. This eliminates the need for external CRC validation or redundant storage, improving system reliability in safety-critical automotive applications without increasing firmware complexity.
