Product details
Overview
M24C04-DRDW8TP/K from STMicroelectronics is a 4-Kbit I²C serial EEPROM with 512 × 8-bit organization, 16-byte page size, and dedicated 16-byte identification page. It operates across -40 °C to +105 °C at 1.7–5.5 V supply, supports 1 MHz I²C bus speed, and features embedded ECC for enhanced data integrity in automotive body control modules.
For engineers reviewing the M24C04-DRDW8TP/K datasheet, M24C04-DRDW8TP/K pinout, M24C04-DRDW8TP/K application, or M24C04-DRDW8TP/K equivalent, key selection criteria include write endurance at high temperature (900k cycles @ 105 °C), identification page lockability, Schmitt-trigger noise immunity, and TSSOP8 package compatibility with space-constrained PCB layouts.
Technical Context
The device implements a true EEPROM cell structure with on-die high-voltage charge pump, enabling byte- and page-level writes without external VPP. Its I²C slave interface conforms to standard, fast, and high-speed modes up to 1 MHz, with ACK polling support to minimize software wait time during write cycles.
It integrates dedicated logic for identification page access (device code 0x20E009 at addresses 00h–02h) and permanent lock control via WC pin assertion. The internal address counter auto-increments after each successful write, and roll-over behavior is explicitly defined for page writes crossing page boundaries.
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 minimal bus overhead. |
| I²C speed | Up to 1 MHz - reduces transaction time for configuration updates in real-time systems. |
| Write cycle time | ≤4 ms for byte or page write - allows deterministic timing budgeting in time-critical boot sequences. |
| Endurance @ 105 °C | 900,000 write cycles - ensures reliable recalibration data logging in under-hood automotive ECUs. |
| Data retention @ 105 °C | >50 years - guarantees long-term validity of calibration constants without refresh. |
| Supply voltage | 1.7 V to 5.5 V - supports direct interfacing with 3.3 V and 5 V microcontrollers without level shifters. |
| ESD rating | 4000 V HBM - provides robustness against handling and board-level ESD events in manufacturing environments. |
Pinout & Package
TSSOP8 (DW) package: 8-lead thin shrink small outline, 3 mm × 6.4 mm body, 0.65 mm pitch, RoHS-compliant and halogen-free (ECOPACK2®).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E2, E1 | Chip Enable address inputs | Set 2-bit device select code (b3,b2) to enable one of up to four devices on same I²C bus; floating = low. |
| SDA | Serial Data I/O | Open-drain bidirectional line requiring external pull-up; supports wire-OR with other I²C slaves. |
| SCL | Serial Clock input | Master-generated clock strobe; sampled on rising edge for data capture and generation. |
| WC | Write Control input | Hardware write protection: high = full memory locked; low or floating = write enabled. |
| VSS | Ground reference | Return path for VCC and all internal logic; must be low-impedance for noise immunity. |
| VCC | Supply voltage | Power source for EEPROM core and interface logic; decoupling capacitor required per layout guidelines. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C04C-SSHM-T | 4-Kbit I²C EEPROM, 1.7–5.5 V, but rated only to 85 °C; no identification page; 1 million write cycles @ 85 °C. | Lacks AEC-Q100 qualification and high-temp endurance; unsuitable for under-hood use. | Select when cost sensitivity outweighs extended temperature needs and identification page functionality. |
| BR24G04NUX-10 | 4-Kbit I²C EEPROM, -40 °C to +105 °C, 1.6–5.5 V, but uses different addressing scheme (no E2/E1 pins); no identification page. | Requires different PCB layout and firmware initialization; lacks hardware write lock via WC pin. | Choose only if existing design already uses ROHM's BR24G series and can accommodate pinout and protocol differences. |
Compared with AT24C04C-SSHM-T and BR24G04NUX-10, the M24C04-DRDW8TP/K uniquely combines AEC-Q100 Grade 2 qualification, 105 °C endurance, identification page lockability, and explicit WC-pin hardware write protection - making it the sole option for safety-critical automotive and industrial applications requiring traceable, tamper-resistant configuration storage.

FAQ
What is the function of the WC pin on the M24C04-DRDW8TP/K?
The WC (Write Control) pin is a hardware write-protection input. When driven high, it disables all write operations to both main memory and identification page - no data bytes are acknowledged. When low or floating, writes are enabled. This provides deterministic, glitch-immune protection independent of firmware state.
Does the M24C04-DRDW8TP/K support 1 MHz I²C operation across its full temperature range?
Yes. The device supports 1 MHz I²C communication from -40 °C to +105 °C, as verified in Section 8 (DC and AC parameters) of the datasheet. AC characteristics including tLOW, tHIGH, and setup/hold times are guaranteed across this range with appropriate bus pull-up strength.
How is the identification page structured and what data does it contain?
The identification page is a dedicated 16-byte area. Bytes 00h–02h contain ST's factory-programmed device ID (0x20, 0xE0, 0x09). Remaining bytes (03h–0Fh) are user-writable for application-specific data and can be permanently locked in read-only mode using the Lock Identification Page instruction.
Can the M24C04-DRDW8TP/K be used in a 1.8 V system?
Yes. Its 1.7–5.5 V operating voltage range includes 1.8 V. All DC and AC specifications - including logic thresholds, write timing, and I²C compatibility - are fully characterized down to 1.7 V, enabling direct interface with 1.8 V microcontrollers without level translation.
