Product details
Overview
M24512-DRMN8TP/K from STMicroelectronics is a 512-Kbit (64 Kbyte) I²C serial EEPROM with 128-byte page size, 1.7–5.5 V supply range, -40 °C to +105 °C operation, and embedded ECC for enhanced data integrity-used in automotive body control modules for storing calibration data, configuration profiles, and fault logs.
For engineers reviewing the M24512-DRMN8TP/K datasheet, M24512-DRMN8TP/K pinout, M24512-DRMN8TP/K application, or M24512-DRMN8TP/K equivalent, key selection criteria include I²C bus speed support (up to 1 MHz), write endurance at high temperature (900 k cycles @ 105 °C), identification page lockability, Schmitt-trigger noise immunity, and AEC-Q100 Grade 2 qualification.
Technical Context
The device operates as an I²C slave with fixed 7-bit device type identifier (1010b for memory, 1011b for identification page) and user-configurable 3-bit chip enable (E2/E1/E0), enabling up to eight devices on one bus. It implements byte- and page-write protocols with ACK polling support to minimize write latency.
Internal architecture includes a dedicated 128-byte identification page with factory-programmed ST device code (20h/E0h/10h) and user-writable/application-lockable fields, plus ECC logic applied across all memory pages to detect and correct single-bit errors during read operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory capacity | 512 Kbit (64 Kbytes), organized as 512 × 128-byte pages - enables efficient block-level firmware parameter storage. |
| I²C clock frequency | Up to 1 MHz - supports high-speed configuration updates in real-time automotive diagnostics. |
| Write cycle time | ≤ 4 ms for byte or page write - reduces system blocking time during nonvolatile parameter save operations. |
| Endurance @ 105 °C | 900,000 write cycles - ensures reliable recalibration logging over full vehicle lifetime in under-hood ECUs. |
| Data retention @ 105 °C | 50+ years - guarantees long-term validity of safety-critical calibration data 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 - withstands handling and board-level transients in automotive manufacturing environments. |
Pinout & Package
Package: TSSOP8 (DW), 3 mm × 6.4 mm, 0.65 mm pitch, RoHS-compliant and halogen-free (ECOPACK2®).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E2, E1, E0 | Chip Enable address inputs | Set 3-bit device select code (b2–b0); tied high/low to configure unique I²C address among up to 8 devices on same bus. |
| SDA | Serial Data bidirectional line | Open-drain I/O requiring external pull-up; supports wire-OR with other I²C slaves for shared bus topology. |
| SCL | Serial Clock input | Master-generated clock strobe; sampled on rising edge for synchronous data transfer. |
| WC | Write Control input | Hardware write-protection: high = entire memory locked; low/floating = write enabled - prevents accidental corruption. |
| VSS | Ground reference | Return path for all internal circuitry; must be low-impedance connection to avoid noise coupling into I²C signals. |
| VCC | Power supply input | Accepts 1.7–5.5 V; internal voltage regulation enables stable EEPROM operation across wide battery voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC logic | Single-bit error correction per memory access - eliminates need for external software CRC checks in safety-critical reads. |
| Identification page | 128-byte dedicated area with factory ST ID (20h/E0h/10h) and user-lockable fields - enables secure device authentication and immutable parameter storage. |
| Schmitt trigger inputs | On SCL, SDA, WC, and E pins - rejects bus noise up to 30% VCC, improving robustness in electrically noisy automotive harnesses. |
| AEC-Q100 Grade 2 | Qualified for -40 °C to +105 °C ambient operation - meets automotive powertrain and chassis module reliability requirements. |
| Page write capability | 128-byte atomic writes - reduces I²C transaction count by >95% vs. byte-write for bulk configuration saves. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C512B-MAHM-T | 512 Kbit I²C EEPROM, 1 MHz max, but rated only to 85 °C and lacks identification page/ECC. | Not AEC-Q100 qualified; unsuitable for under-hood use above 85 °C or safety-critical calibration storage. | Select only for industrial or consumer applications where extended temperature and ECC are not required. |
| BR24G512FJ-3GE2 | 512 Kbit I²C EEPROM with 105 °C rating and built-in write protect, but no identification page or ECC logic. | Supports automotive ambient temp but lacks factory ID verification and bit-error correction capability. | Choose when basic high-temp EEPROM functionality suffices and calibration authenticity/ECC are handled externally. |
Compared with AT24C512B-MAHM-T and BR24G512FJ-3GE2, the M24512-DRMN8TP/K uniquely combines AEC-Q100 Grade 2 qualification, embedded ECC, and a lockable identification page-making it the only option for ISO 26262 ASIL-B–aligned calibration storage where data integrity and provenance are mandatory.

FAQ
Is the M24512-DRMN8TP/K pin-compatible with earlier M24512-D series variants?
Yes - the M24512-DRMN8TP/K uses the same TSSOP8 (DW) package and identical pinout as M24512-DRE and M24512-DRMN6TP/K. All share identical E2/E1/E0, SDA, SCL, WC, VCC, and VSS assignments per Figure 2 of DocID027240 Rev 2.
How is the identification page locked, and can it be unlocked?
The identification page is permanently locked via the "Lock Identification Page" instruction (Section 4.1.4). Once locked, the page becomes read-only and cannot be re-enabled for writing - this is a one-time irreversible hardware fuse action confirmed by reading lock status bit 0 in the identification page.
Does the embedded ECC correct errors during write operations?
No - ECC operates only during read operations. The device calculates and stores ECC bits during write, then verifies and corrects single-bit errors transparently on subsequent reads. Writes themselves are not ECC-validated; integrity relies on proper voltage and timing margins per DC/AC specs.
What is the maximum bus capacitance supported at 1 MHz I²C operation?
Per Figure 11 in DocID027240 Rev 2, the M24512-DRMN8TP/K supports ≤ 100 pF total bus capacitance at 1 MHz with standard 2.2 kΩ pull-up resistors. Exceeding this requires reducing clock frequency or using active bus buffers to maintain rise/fall time compliance.
