Product details
Overview
M24C04-DRMN8TP/K from STMicroelectronics is a 4-Kbit (512-byte) I²C-compatible serial EEPROM with 16-byte page architecture, rated for operation from -40 °C to +105 °C and 1.7 V to 5.5 V supply. It features Schmitt-trigger inputs, 4 ms max byte/page write time, and an additional lockable 16-byte Identification Page used for device ID storage or application-specific parameters in automotive body control modules.
For engineers reviewing the M24C04-DRMN8TP/K datasheet, M24C04-DRMN8TP/K pinout, M24C04-DRMN8TP/K application, or M24C04-DRMN8TP/K equivalent, key selection criteria include I²C bus speed support (1 MHz/400 kHz/100 kHz), extended temperature endurance (1.2M writes at 85 °C), ECC-enhanced data integrity, and WC-pin-based hardware write protection.
Technical Context
The M24C04-DRMN8TP/K implements a true EEPROM memory array organized as 32 pages × 16 bytes, with embedded Error Correction Code (ECC x1) logic to detect and correct single-bit errors during read operations. Its I²C slave interface supports standard, fast, and fast-plus modes up to 1 MHz, with ACK polling capability to minimize write latency.
It uses dual Chip Enable inputs (E1, E2) to configure 2-bit device addressing, enabling up to four devices on one I²C bus. The Write Control (WC) pin provides hardware-level write inhibition across the entire memory array - including the Identification Page - when driven high, while allowing full read access regardless of WC state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4 Kbits (512 bytes), organized as 32 × 16-byte pages for efficient firmware parameter storage. |
| I²C speed support | Up to 1 MHz - enables high-throughput configuration updates in real-time control systems. |
| Write cycle endurance | 1.2 million cycles at 85 °C - validated for long-term reliability in under-hood automotive applications. |
| Data retention | 50+ years at 105 °C - ensures calibration data persistence over full vehicle lifecycle without refresh. |
| Supply voltage range | 1.7 V to 5.5 V - compatible with 3.3 V and 5 V microcontroller I/O domains without level shifting. |
| ESD protection | 4000 V HBM - robust against handling and board-level electrostatic discharge in manufacturing environments. |
| Operating temperature | -40 °C to +105 °C - meets AEC-Q100 Grade 2 requirements for passenger compartment and engine bay use. |
Pinout & Package
Package: TSSOP8 (3 mm × 6.4 mm, 0.65 mm pitch), RoHS-compliant and halogen-free (ECOPACK2®).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E2 | Chip Enable (MSB) | Configures 2-bit device address (with E1); tied high/low to select one of four possible I²C addresses on shared bus. |
| E1 | Chip Enable (LSB) | Combines with E2 to set unique slave address; floating defaults to low for fixed base address assignment. |
| SDA | Serial Data I/O | Open-drain bidirectional line requiring external pull-up; supports multi-master arbitration and wire-OR bus topology. |
| SCL | Serial Clock Input | Master-generated clock synchronizing all data transfers; Schmitt-trigger input rejects noise on long traces. |
| WC | Write Control | Hardware lock: high = full memory write inhibit (including Identification Page); low or floating = write enabled. |
| VSS | Ground Reference | System ground return path; must be low-impedance connection to ensure stable internal voltage regulation. |
| VCC | Supply Voltage | 1.7–5.5 V power input; internal charge pump enables EEPROM programming across full voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Identification Page | 16-byte dedicated area storing ST device ID (0x20, 0xE0, 0x09) and user-configurable parameters, lockable to permanent read-only mode. |
| ECC x1 error correction | On-the-fly single-bit error detection and correction during reads, improving data reliability in electrically noisy automotive environments. |
| Fast write timing | ≤4 ms byte or page write - reduces system wait time during critical configuration updates (e.g., airbag sensor calibration). |
| Extended voltage range | 1.7 V minimum operating voltage - supports brown-out operation during battery voltage sag in start-stop systems. |
| RoHS & ECOPACK2® | Halogen-free, lead-free packaging compliant with automotive environmental standards and end-of-life recycling requirements. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C04D-SSHM-T | Same 4-Kbit capacity and TSSOP8 package, but rated only to 85 °C and lacks Identification Page and ECC. | Not qualified for under-hood or high-reliability medical use; suitable for commercial-grade consumer electronics. | Select if cost sensitivity outweighs extended temperature and ECC requirements. |
| M95040-DRMN6TP/K | Same ST part family, SPI interface instead of I²C; identical temperature/voltage specs and Identification Page. | Requires SPI-capable host MCU; incompatible with I²C-only systems; higher pin count needed for CS signal. | Choose only when existing board design uses SPI peripherals and I²C bus is congested. |

FAQ
What is the function of the WC pin on M24C04-DRMN8TP/K?
The WC (Write Control) pin provides hardware-level write protection: when driven high, it disables all write operations to both main memory and the Identification Page, while preserving full read access. This prevents accidental overwrites during firmware updates or power transients. WC can be left floating (defaulting to low) or pulled low to enable writes.
Does M24C04-DRMN8TP/K support 1 MHz I²C communication?
Yes - the device fully supports Fast-Plus Mode I²C up to 1 MHz, as confirmed in its production datasheet (DocID027421 Rev 2). This requires appropriate bus capacitance (<400 pF) and pull-up resistor sizing (typically 1–2 kΩ at 3.3 V), per Figures 10–11 in the datasheet.
How is the Identification Page used and protected?
The 16-byte Identification Page stores ST's device ID (bytes 0–2: 0x20, 0xE0, 0x09) and up to 13 bytes of user data. It can be written freely until locked via the "Lock Identification Page" instruction, after which it becomes permanently read-only - preventing tampering with calibration or security-critical values.
Is ECC implemented in hardware or software for this EEPROM?
ECC is implemented in dedicated on-die logic - not firmware - and operates transparently during every read operation. It detects and corrects single-bit errors in real time using Hamming code, requiring no host MCU intervention or additional software overhead.
