Product details
Overview
M24C08-DRMN8TP/K from STMicroelectronics is an 8-Kbit I²C serial EEPROM with 1024 × 8-bit memory organization, 16-byte page size, and extended industrial temperature operation up to +105 °C. It features Schmitt-trigger inputs for noise immunity, 4 ms max byte/page write time, and a dedicated 16-byte identification page with permanent lock capability - deployed in automotive body control modules for calibration storage and fault log retention.
For engineers reviewing the M24C08-DRMN8TP/K datasheet, M24C08-DRMN8TP/K pinout, M24C08-DRMN8TP/K application, or M24C08-DRMN8TP/K equivalent, key selection criteria include I²C bus speed support (1 MHz), write endurance at high temperature (900 k cycles @ 105 °C), identification page locking behavior, and TSSOP8 package compatibility with AEC-Q100 Grade 2 reliability requirements.
Technical Context
The device operates as a slave on the I²C bus with full compatibility across standard (100 kHz), fast (400 kHz), and fast-plus (1 MHz) modes. Its internal architecture includes an address counter, page decoder, and embedded Error Correction Code (ECC x1) logic to enhance data integrity during read/write operations.
It supports two distinct addressing spaces: main memory (device type identifier 1010b) and identification page (1011b), each with separate device select codes and address mapping rules. Write protection is controlled via the WC pin, enabling hardware-level inhibition of all memory writes when driven high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Kbits (1024 bytes), organized as 64 pages × 16 bytes - enables efficient firmware parameter storage with minimal bus overhead per page access. |
| I²C Speed Support | Up to 1 MHz - allows high-throughput configuration updates in time-critical automotive subsystems without requiring clock stretching. |
| Operating Voltage | 1.7 V to 5.5 V - supports direct interfacing with 1.8 V, 3.3 V, and 5 V microcontrollers without level-shifting circuitry. |
| Temperature Range | −40 °C to +105 °C - qualified to AEC-Q100 Grade 2, suitable for under-hood and powertrain ECU applications. |
| Write Endurance | 900 k cycles at 105 °C - ensures reliable logging of diagnostic events over full vehicle lifetime in high-temperature environments. |
| Data Retention | 50+ years at 105 °C - guarantees long-term validity of calibration data and security keys without periodic refresh. |
| ESD Protection | 4000 V HBM - provides robustness against handling and system-level electrostatic discharge in manufacturing and field service. |
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 | Chip Enable | Hardware-selectable device address bit (b3 of device select code); tied high/low to configure I²C slave address among up to two devices on same bus. |
| SDA | Serial Data I/O | Open-drain bidirectional line; requires external pull-up; carries address, command, and data bits in I²C protocol frames. |
| SCL | Serial Clock Input | Master-generated clock synchronizing all data transfers; sampled on rising edge for input, drives timing for output. |
| WC | Write Control | Active-high hardware lock: when high, disables all write operations to main memory and identification page - no software override possible. |
| VSS | Ground Reference | Return path for VCC supply and I/O signals; must be low-impedance connection to minimize noise coupling into SDA/SCL. |
| VCC | Supply Voltage | Power input (1.7–5.5 V); internal voltage regulator enables stable EEPROM operation across wide input range. |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated Identification Page | 16-byte reserved space with factory-programmed ST device ID (0x20, 0xE0, 0x0A) and user-writable fields - enables secure device authentication and application-specific parameter binding. |
| Hardware Write Lock (WC) | Pin-driven global write inhibit: eliminates risk of accidental overwrite during power transitions or firmware bugs - no register-based lock required. |
| Embedded ECC Logic | Single-bit error correction per byte read - improves functional safety compliance by detecting/correcting bit flips caused by radiation or aging in automotive environments. |
| Fast Write Cycle | ≤4 ms byte or page write time - reduces bus occupancy and enables rapid logging of transient events like crash data or thermal faults. |
| Schmitt Trigger Inputs | Hysteresis on SCL and SDA pins - rejects noise spikes up to 30% of VCC, eliminating need for external RC filtering in noisy engine bay layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C08D-SSHM-T (Microchip) | Same 8-Kbit capacity, 1 MHz I²C, but lacks identification page and hardware WC pin; uses software write protect. | No hardware-level lock for calibration data - requires additional MCU firmware checks to prevent accidental writes. | Select when cost sensitivity outweighs need for AEC-Q100 qualification and hardware write lock. |
| BR24G08NUX-10 (ROHM) | Includes identification page and WC pin, but rated only to 105 °C with reduced endurance (400 k cycles @ 105 °C) and no AEC-Q100 certification. | Not qualified for automotive under-hood use; limited suitability for safety-critical logging where long-term reliability is mandated. | Select for industrial consumer applications where AEC-Q100 is not required and lower write endurance is acceptable. |
Compared with AT24C08D-SSHM-T and BR24G08NUX-10, the M24C08-DRMN8TP/K uniquely combines AEC-Q100 Grade 2 qualification, hardware WC lock, and 900 k write cycles at 105 °C - making it the only option certified for automotive powertrain and chassis control systems requiring guaranteed data integrity over full vehicle life.

FAQ
What is the function of the WC pin on the M24C08-DRMN8TP/K?
The WC (Write Control) pin is an active-high hardware lock that globally disables all write operations to both main memory and the identification page. When driven high, the device acknowledges device select and address bytes but NAKs all data bytes - preventing accidental or malicious overwrites without requiring software intervention or register configuration.
Does the M24C08-DRMN8TP/K support 1 MHz I²C communication in all operating conditions?
Yes, the M24C08-DRMN8TP/K supports 1 MHz I²C operation across its full specified voltage range (1.7 V to 5.5 V) and temperature range (−40 °C to +105 °C), as confirmed by AC characteristics tables in the official datasheet (DocID027422 Rev 2, Tables 11–12). Bus timing margins remain compliant with I²C specification under worst-case conditions.
How is the identification page locked permanently on the M24C08-DRMN8TP/K?
Permanent lock is achieved by executing the "Lock Identification Page" instruction (detailed in Section 4.1.4 of the datasheet), which sets an internal fuse. Once locked, the entire 16-byte identification page becomes read-only - subsequent write attempts to any byte in that page are ignored, and no unlock command exists. This action is irreversible and hardware-enforced.
Is the M24C08-DRMN8TP/K pin-compatible with other packages in the M24C08-DRE family?
No - the M24C08-DRMN8TP/K uses the TSSOP8 (DW) package, while other variants use SO8N (MN) or WFDFPN8 (MF). Although all share identical pin functions and numbering (E2, SDA, SCL, WC, VSS, VCC), their physical footprints, thermal characteristics, and reflow profiles differ significantly; PCB layout and assembly processes are not interchangeable between packages.
