Product details
Overview
M24128-DRMN8TP/K from STMicroelectronics is a 128-Kbit (16 Kbyte) I²C-compatible serial EEPROM with 64-byte page size, -40 °C to 105 °C operating range, and 1.7 V to 5.5 V supply voltage. It features an additional lockable 64-byte Identification Page for device ID storage or application parameters, and embeds Error Correction Code logic to enhance data integrity in automotive and industrial control systems.
For engineers reviewing the M24128-DRMN8TP/K datasheet, M24128-DRMN8TP/K pinout, M24128-DRMN8TP/K application, or M24128-DRMN8TP/K equivalent, key selection criteria include I²C bus speed support (up to 1 MHz), write endurance at elevated temperature (900 k cycles at 105 °C), identification page locking capability, and RoHS-compliant TSSOP8 package compatibility with AEC-Q100 Grade 2 reliability requirements.
Technical Context
The device operates as an I²C slave with standard 7-bit addressing plus R/W bit, supporting device select codes 1010b (main memory) and 1011b (Identification Page). Chip Enable inputs E2–E0 allow up to eight devices on one bus, while Write Control (WC) enables hardware-level write protection for the entire memory array.
Internal architecture includes a 256-page × 64-byte memory organization, Schmitt-trigger inputs for noise immunity, and ACK-polling support to minimize write delays. The embedded ECC logic corrects single-bit errors and detects double-bit errors within each 64-byte page during read operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory capacity | 128 Kbits (16 Kbytes), organized as 256 pages × 64 bytes - enables efficient block writes without cross-page boundary handling. |
| I²C bus speed | Up to 1 MHz - supports high-throughput configuration updates in real-time control loops. |
| Operating temperature | -40 °C to 105 °C - qualified per AEC-Q100 Grade 2 for under-hood automotive and industrial power electronics. |
| Write endurance | 900 k cycles at 105 °C - ensures reliable parameter logging over extended service life in thermal-stressed environments. |
| Data retention | 50+ years at 105 °C - guarantees long-term calibration data integrity without refresh in sealed systems. |
| Supply voltage | 1.7 V to 5.5 V - interoperable with 1.8 V, 3.3 V, and 5 V microcontrollers without level-shifting. |
| ESD protection | 4000 V HBM - reduces risk of field failure during handling and board assembly. |
Pinout & Package
TSSOP8 (DW) package: 8-lead thin shrink small outline, 3 mm × 6.4 mm body, 0.65 mm pitch, 150 mil width, 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 eight devices on same bus. |
| SDA | Serial Data I/O | Open-drain bidirectional line requiring external pull-up; transmits/receives address/data bytes and ACK/NACK bits per I²C protocol. |
| SCL | Serial Clock input | Master-generated clock synchronizing all data transfers; sampled on rising edge for input, controls timing of SDA output transitions. |
| WC | Write Control input | Hardware write lock: high = full memory write inhibition; low or floating = write enabled - prevents accidental corruption during power transients. |
| VCC | Supply voltage | 1.7–5.5 V power rail; internal voltage regulation enables stable operation across wide input range without external LDO. |
| VSS | Ground reference | Return path for all internal circuitry; must be low-impedance connection to minimize noise coupling into sensitive analog blocks. |
Key Features
| Feature | Design Value |
|---|---|
| Identification Page with lock | 64-byte dedicated area storing ST device ID (00h–02h) and user data; permanently lockable to prevent overwrite after programming. |
| Embedded ECC logic | Single-bit error correction and double-bit error detection per 64-byte page - eliminates need for external software CRC overhead in safety-critical firmware. |
| Fast write cycle | ≤4 ms byte or page write time - enables rapid parameter updates in time-constrained applications like motor startup sequences. |
| Schmitt-trigger inputs | Hysteresis on SCL, SDA, WC, and E2–E0 pins - rejects noise spikes up to 30% of VCC, improving robustness in electrically noisy engine control units. |
| Extended voltage range | 1.7 V minimum VCC - supports direct interface with ultra-low-power MCUs and battery-backed systems down to coin-cell voltages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C128C-SSHL-T (Microchip) | Same 128 Kbit capacity and TSSOP8 package, but rated only to 85 °C and lacks Identification Page + lock feature. | Not suitable for under-hood automotive use; requires external software-based write protection instead of hardware WC pin. | Select when cost sensitivity outweighs extended temperature and secure ID page requirements. |
| BR24G128FJ-3GE2 (Rohm) | Includes 64-byte ID page but no ECC logic; write endurance drops to 300 k cycles at 105 °C. | Acceptable for consumer-grade industrial controls where ECC is not mandated, but insufficient for ASIL-B systems. | Choose only if system-level error detection (e.g., host MCU CRC) compensates for missing embedded ECC. |
Compared with AT24C128C-SSHL-T and BR24G128FJ-3GE2, the M24128-DRMN8TP/K uniquely combines AEC-Q100 Grade 2 qualification, hardware-lockable ID page, and ECC-protected memory - making it the sole option meeting functional safety and long-term data integrity requirements in automotive and medical applications.

FAQ
What is the function of the WC pin on M24128-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 Identification Page, preventing accidental data corruption during power-up/down or EMI events. When low or floating, writes are enabled. This differs from software-only lock mechanisms by offering deterministic, voltage-independent protection.
How does the Identification Page differ from standard memory pages?
The Identification Page is a dedicated 64-byte area accessible via device select code 1011b instead of 1010b. It contains factory-programmed ST device ID (bytes 00h–02h) and user-writable space, and supports permanent lock via dedicated instruction - unlike main memory, which uses byte/page write commands only. Once locked, no further writes are possible even with WC = low.
Is M24128-DRMN8TP/K compatible with 1.8 V I²C masters?
Yes - its 1.7 V to 5.5 V VCC range and Schmitt-trigger inputs ensure reliable operation with 1.8 V I²C masters. The SDA and SCL pins tolerate input voltages up to VCC + 0.5 V, and the device generates valid ACK/NACK signals at 1.8 V logic levels without external level shifters, provided pull-up resistors are sized for 1.8 V bus voltage.
What does "ECOPACK2®" mean for this part?
ECOPACK2® is STMicroelectronics' eco-design standard certifying that M24128-DRMN8TP/K meets RoHS Directive 2011/65/EU and is halogen-free (≤900 ppm bromine, ≤900 ppm chlorine, total ≤1500 ppm halogens). It also confirms compliance with REACH SVHC thresholds and supports lead-free reflow soldering per JEDEC J-STD-020.
