Product details
Overview
M24C16-DRMN3TP/K from STMicroelectronics is an AEC-Q100 Grade 1 automotive serial EEPROM with 16 Kbits (2048 × 8) memory organized in 128 pages of 16 bytes, supporting I²C bus speeds up to 1 MHz, operating from −40 °C to 125 °C at 1.7–5.5 V, and featuring embedded ECC for single-bit error correction. It is used in engine control units, airbag modules, and ADAS sensors requiring nonvolatile parameter storage under harsh thermal conditions.
For engineers reviewing the M24C16-DRMN3TP/K datasheet, M24C16-DRMN3TP/K pinout, M24C16-DRMN3TP/K application, or M24C16-DRMN3TP/K equivalent, key selection criteria include its 4 million write cycles at 25 °C, 50-year data retention at 125 °C, write-protect via WC pin, identification page locking capability, and TSSOP8 package compatibility with automotive PCB layouts.
Technical Context
The M24C16-DRMN3TP/K implements a true EEPROM core with on-die charge-pump HV generator and sequencer, enabling byte- and page-write operations without external high-voltage programming. Its I²C slave interface complies fully with standard, fast, and fast-plus modes (100 kHz/400 kHz/1 MHz), with Schmitt-triggered SDA/SCL inputs ensuring robust noise immunity in automotive harness environments.
It integrates ECC logic per byte for automatic single-bit error detection and correction during read access, and includes a dedicated 16-byte identification page-separate from main memory-with programmable lock functionality. Write protection is controlled by the WC pin, which disables all writes when driven high, independent of I²C address decoding.
Key Specifications

Pinout & Package
Package: TSSOP8 (169 mil width), RoHS-compliant and halogen-free (ECOPACK2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDA) | Serial data bidirectional I/O | Open-drain I²C bus line requiring external pull-up; supports wired-AND with other slaves on same bus segment. |
| 2 (VSS) | Ground reference | Primary return path for internal logic and I/O drivers; must be low-impedance connection to system ground plane. |
| 3 (SCL) | Serial clock input | Master-generated clock synchronizing all I²C transfers; Schmitt trigger ensures noise immunity on long traces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C16D-SSHM-T | 16 Kbit I²C EEPROM, AEC-Q100 Grade 2 (−40 °C to 105 °C), no embedded ECC, no identification page. | Limited to cabin modules or infotainment where extended temperature and ECC are not required. | Select when cost sensitivity outweighs need for 125 °C operation or ECC; verify WC pin absence does not compromise system write safety. |
| BR24G16NUX-101 | 16 Kbit I²C EEPROM, AEC-Q100 Grade 1, 1.7–5.5 V, but only supports up to 400 kHz I²C clock and lacks WC pin. | Suitable for body control modules with moderate timing constraints and no hardware write-lock requirement. | Choose if 1 MHz bandwidth is unnecessary and system-level write protection is handled in firmware instead of hardware. |
Compared with AT24C16D-SSHM-T and BR24G16NUX-101, the M24C16-DRMN3TP/K uniquely combines 125 °C operation, 1 MHz I²C, hardware WC pin, and ECC - making it the only option for safety-critical under-hood applications requiring deterministic write protection and bit-error resilience.

FAQ
What is the function of the WC pin on the M24C16-DRMN3TP/K?
The WC (Write Control) pin is a hardware-level enable/disable input for all write operations. When driven high, it prevents any modification to both main memory and the identification page - even valid I²C write commands are ignored and return NoACK. This provides fail-safe protection against firmware bugs or bus noise corrupting critical calibration data during vehicle operation.
Does the M24C16-DRMN3TP/K support I²C fast-plus mode (1 MHz)?
Yes, the M24C16-DRMN3TP/K fully supports I²C fast-plus mode up to 1 MHz, as confirmed in its official datasheet (DS10068 Rev 7). This allows high-speed parameter updates in time-sensitive applications like real-time ADAS calibration, provided the host controller and bus capacitance meet fast-plus electrical requirements (e.g., ≤400 pF total bus load).
How is the identification page locked, and can it be unlocked?
The identification page is locked using a dedicated "lock ID" instruction: device select code 1011b, address bit A7 = 1, and data byte = xxxx xx1x. Once executed, the lock is permanent and irreversible - no command or voltage sequence can unlock it. This ensures tamper-proof storage of device identity or safety-critical parameters in production vehicles.
What is the purpose of the ECC logic in the M24C16-DRMN3TP/K?
The embedded ECC (Error Correction Code) logic performs single-bit error correction transparently during every read operation. It detects and fixes flipped bits caused by radiation or aging effects, eliminating silent data corruption. This is implemented per byte in hardware and requires no software intervention, significantly improving data integrity in safety-critical automotive applications without increasing host CPU overhead.
