Product details

Overview

M24C16-DRMN8TP/K from STMicroelectronics is a 16-Kbit (2 Kbyte) I²C-compatible serial EEPROM with 16-byte page architecture, Schmitt-trigger inputs, and extended industrial temperature operation up to 105 °C. It features an additional lockable 16-byte Identification Page for device ID storage or application parameters, operates across 1.7–5.5 V, and supports I²C bus speeds up to 1 MHz - deployed in automotive body control modules for storing calibration data and configuration settings.

For engineers reviewing the M24C16-DRMN8TP/K datasheet, M24C16-DRMN8TP/K pinout, M24C16-DRMN8TP/K application, or M24C16-DRMN8TP/K equivalent, key selection considerations include write endurance at elevated temperature (900 k cycles at 105 °C), identification page lockability, WC pin-based hardware write protection, and SO8N (MN) RoHS-compliant packaging with ECOPACK2® certification.

Technical Context

The device implements a true EEPROM memory array organized as 128 pages × 16 bytes (2048 × 8 bits), with embedded single-bit Error Correction Code (ECC) logic enhancing data integrity during read operations. Its I²C slave interface conforms fully to standard, fast, and high-speed modes (100 kHz/400 kHz/1 MHz), supporting Start/Stop conditions, ACK/NACK handshaking, and 7-bit device addressing with R/W bit.

Write Control (WC) provides hardware-level memory protection: when driven high, it inhibits all write operations to both main array and Identification Page while still acknowledging device select and address bytes. The Identification Page (16 bytes) contains factory-programmed ST device ID (0x20, 0xE0, 0x0B at offsets 00h–02h) and user-writable/application-parameter space, permanently lockable to read-only mode via dedicated Lock ID instruction.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory size	16 Kbit (2048 × 8 bits), enabling compact non-volatile storage for firmware flags, sensor offsets, or device-specific configuration.
Page size	16 bytes per page; limits burst writes to page boundaries and defines minimum erase granularity for field updates.
Max I²C speed	1 MHz; supports high-throughput parameter loading in time-critical boot sequences without external timing constraints.
Operating voltage	1.7 V to 5.5 V; ensures compatibility with 1.8 V, 3.3 V, and 5 V microcontroller I/O domains without level shifting.
Temp range	−40 °C to +105 °C; qualified to AEC-Q100 Grade 2, suitable for under-hood automotive electronics mounting.
Write endurance	900 k cycles at 105 °C; guarantees reliable logging of thermal event counters or fault history in high-temp environments.
Data retention	50+ years at 105 °C; maintains calibration coefficients and security keys over full vehicle lifetime without refresh.

Pinout & Package

Package: SO8N (MN), 8-lead plastic small outline, 4.9 × 6 mm body, 150 mil width, RoHS-compliant and halogen-free (ECOPACK2®).

Pin/Terminal	Circuit Role	Design Meaning
1 (A0)	Chip Enable Address	LSB of hardware device address; tied high/low to select one of four possible I²C addresses on shared bus.
2 (A1)	Chip Enable Address	MSB of hardware device address; used with A0 to configure unique I²C slave address (1010xxR/W).
3 (VSS)	Ground reference	System ground return path; must be low-impedance and decoupled near VCC pin to suppress noise coupling into SDA/SCL.
4 (SDA)	Serial Data I/O	Open-drain bidirectional line; requires external pull-up resistor (value depends on bus capacitance and speed) for I²C compliance.
5 (SCL)	Serial Clock Input	Master-generated clock; rising edge samples SDA, falling edge allows SDA transitions - Schmitt trigger enables robust noise immunity.
6 (WC)	Write Control Input	Active-high hardware lock: disables all writes when asserted; floating or low enables write access to memory and ID page.
7 (VCC)	Supply voltage	Power input (1.7–5.5 V); must be filtered with ≥100 nF ceramic capacitor placed adjacent to pin for stable EEPROM operation.
8 (NC)	No Connect	Internally unconnected; left floating or grounded per PCB layout best practice - no electrical function.

Key Features

Feature	Design Value
Identification Page with lock	16-byte dedicated area storing ST device ID (0x20/0xE0/0x0B) and user parameters; lockable permanently to prevent overwrite after programming.
Schmitt-trigger inputs	SDA and SCL inputs include hysteresis, rejecting <150 mV of noise on bus lines - critical for noisy automotive or industrial ECU environments.
Short write cycle time	Byte and Page Write both complete within 4 ms max; enables rapid parameter updates without blocking host MCU for extended periods.
Extended voltage range	1.7–5.5 V operation supports direct interfacing with diverse MCUs (e.g., STM32L0, PIC18F, RL78) without regulator or level-shifter circuitry.
ECOPACK2® packaging	RoHS-compliant, halogen-free SO8N package meeting automotive environmental standards and reflow soldering requirements (JEDEC J-STD-020).

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 (Microchip)	Same 16-Kbit I²C EEPROM, but rated only to 85 °C; lacks Identification Page and WC pin; uses different device addressing scheme.	Not suitable for AEC-Q100 Grade 2 automotive use; no hardware write lock or factory ID storage capability.	Select only for cost-sensitive consumer applications below 85 °C where ID page and enhanced protection are unnecessary.
BR24G16NUX-10 (ROHM)	16-Kbit I²C EEPROM with 105 °C rating and built-in write protect, but no dedicated Identification Page; supports 1 MHz only down to 2.5 V.	Lacks factory-programmed ID and user-lockable page; narrower voltage range reduces flexibility in low-VCC designs.	Prefer when board space is constrained (TSSOP8 option available) and ID page functionality is not required.

Compared with AT24C16D-SSHM-T and BR24G16NUX-10, the M24C16-DRMN8TP/K uniquely combines AEC-Q100 Grade 2 qualification, hardware WC pin, factory-programmed ID page, and full 1.7–5.5 V operation - making it the only choice for automotive and high-reliability industrial systems requiring traceable, lockable, and thermally robust non-volatile storage.

FAQ

What is the function of the WC pin on M24C16-DRMN8TP/K?

The WC (Write Control) pin is an active-high hardware lock that disables all write operations to both the main memory array and the Identification Page when driven high. When low or floating, writes are enabled. During WC = high, device select and address bytes are acknowledged, but data bytes receive NoAck - preventing accidental overwrites in safety-critical systems.

Does M24C16-DRMN8TP/K support 1 MHz I²C operation across its full voltage range?

Yes - the device supports 1 MHz I²C communication from 1.7 V to 5.5 V, verified per AC characteristics in Table 12 of the datasheet. At 1.7 V, rise/fall times and bus timing margins remain compliant due to internal current-limited drivers and Schmitt-trigger inputs, eliminating need for voltage-dependent speed derating.

How is the Identification Page protected and what data does it contain?

The Identification Page is a dedicated 16-byte area containing ST's factory-programmed device ID (0x20, 0xE0, 0x0B at offsets 00h–02h) and 13 bytes for user application data. It can be written like a standard page, then permanently locked to read-only mode using the Lock ID instruction - after locking, all write attempts return NoAck and leave contents unchanged.

Is M24C16-DRMN8TP/K pin-compatible with other SO8N-packaged EEPROMs?

No - while the SO8N (MN) package footprint matches industry-standard 8-lead small outline packages, pin functions differ: M24C16-DRMN8TP/K uses pins 1–2 for A0/A1 address inputs and pin 6 for WC, whereas most competing EEPROMs assign those pins to NC or different control signals. Direct replacement requires schematic and layout revision.
