Product details
Overview
M24C16-RMN6TP from STMicroelectronics is a 16-Kbit I²C-compatible EEPROM organized as 2 K × 8 bits, operating with 1.8 V to 5.5 V supply and supporting up to 400 kHz clock frequency. It features 16-byte page write capability, >4 million write cycles, 200-year data retention, and hardware write protection via WC pin. It is used in industrial control modules for parameter storage and calibration data backup.
For engineers reviewing the M24C16-RMN6TP datasheet, M24C16-RMN6TP pinout, M24C16-RMN6TP application, or M24C16-RMN6TP equivalent, key selection considerations include supply voltage range (1.8–5.5 V), TSSOP8 ECOPACK2 packaging, I²C bus timing compliance, and WC-enabled memory lock functionality in embedded systems requiring nonvolatile configuration storage.
Technical Context
The M24C16-RMN6TP implements a standard I²C slave interface with open-drain SDA and input-only SCL, requiring external pull-up resistors. Its internal architecture includes a page latch, HV generator for EEPROM programming, and automatic address incrementing during sequential read/write operations.
Write control (WC) is an active-high hardware lock that disables all write instructions-byte and page-while preserving read access and device addressing acknowledgment. The device integrates a power-on reset (POR) circuit ensuring reliable initialization across its full –40 °C to +85 °C operating range.

Pinout & Package
Package: TSSOP8 (ECOPACK2), 169 mil width, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDA) | Serial Data I/O | Open-drain bidirectional line for I²C data transfer; requires external pull-up resistor to VCC |
| 2 (VSS) | Ground | Reference return path for VCC and all internal logic; must be low-impedance connection |
| 3 (SCL) | Serial Clock Input | Master-generated clock signal synchronizing all I²C transactions; no internal pull-up |
| 4 (NC) | No Connect | Internally unconnected; must remain floating or tied to ground per PCB layout best practice |
| 5 (NC) | No Connect | Internally unconnected; no electrical function; avoid routing signals or vias beneath |
| 6 (NC) | No Connect | Internally unconnected; unused pad; no biasing or termination required |
| 7 (VCC) | Supply Voltage | Primary power rail (1.8–5.5 V); requires local 10–100 nF decoupling capacitor near pin |
| 8 (WC) | Write Control | Active-high hardware lock disabling all write operations; driven high to prevent accidental overwrites |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar I²C EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C16D-SSHM-T (Microchip) | Same 16-Kbit capacity, 1.7–5.5 V supply, but lacks dedicated WC pin; uses software write protection only | Requires firmware-level lock management; unsuitable where hardware-level memory lockdown is mandated | Select when cost sensitivity outweighs need for hardware write disable and board space permits additional GPIO use |
| BR24G16NUX-10 (ROHM) | 16-Kbit, 1.6–5.5 V, built-in write protect register (WP bit), but no WC pin; supports 1 MHz I²C | Enables selective block protection via register, but lacks pin-level instantaneous lock for safety-critical contexts | Prefer when higher-speed I²C communication is needed and software-managed protection suffices for system architecture |
Compared with AT24C16D-SSHM-T and BR24G16NUX-10, the M24C16-RMN6TP uniquely provides a dedicated hardware WC pin for immediate, unconditional memory lock-critical for functional safety designs where firmware cannot be trusted to enforce write protection.

FAQ
What is the function of the WC pin on M24C16-RMN6TP?
The WC (Write Control) pin is an active-high hardware lock that disables all write operations-including byte and page writes-when driven high. Reads remain fully functional, and device addressing is acknowledged, but data bytes are not accepted. This provides fail-safe memory protection independent of firmware state or I²C bus activity.
Can M24C16-RMN6TP operate at 1.8 V while maintaining full 400 kHz I²C speed?
Yes. Per ST's DS9194 Rev 11, the M24C16-R variant (including MN6TP) guarantees full 400 kHz I²C operation across its entire 1.8 V to 5.5 V supply range and –40 °C to +85 °C temperature range, with no derating or timing margin reduction at minimum VCC.
Does M24C16-RMN6TP support sequential read across page boundaries?
Yes. During sequential read, the internal address counter automatically increments after each byte and rolls over from address 07FFh back to 0000h. No special command or address reload is needed-the device outputs consecutive bytes continuously until the master sends a NACK and STOP condition.
Is the TSSOP8 package of M24C16-RMN6TP compatible with standard SO8 footprints?
No. The TSSOP8 (169 mil width) has a narrower body and finer pitch than SO8 (150 mil width). While both have 8 pins, TSSOP8 requires a dedicated footprint with 0.65 mm pitch and 4.4 mm body width; mechanical substitution into SO8 land patterns will cause solder joint reliability issues and misalignment.
