Product details
Overview
M24C16-FMN6TP from STMicroelectronics is a 16-Kbit I²C-compatible EEPROM organized as 2 K × 8 bits, operating with supply voltage from 1.7 V to 5.5 V across –40 °C to +85 °C. It supports 400 kHz I²C bus speed, features 16-byte page write capability, >4 million write cycles, and hardware write protection via WC pin. It is used in industrial sensor calibration storage where low-voltage operation and long-term nonvolatile data retention are required.
For engineers reviewing the M24C16-FMN6TP datasheet, M24C16-FMN6TP pinout, M24C16-FMN6TP application, or M24C16-FMN6TP equivalent, key selection considerations include its 1.7 V minimum VCC, TSSOP8 ECOPACK2 package, WC-enabled full-array write protection, and compatibility with standard I²C master controllers in space-constrained embedded systems.
Technical Context
The M24C16-FMN6TP implements a synchronous serial interface compliant with the I²C protocol, supporting both byte and page write modes (up to 16 bytes per page) with automatic address incrementing and wrap-around behavior. Its internal HV generator enables EEPROM programming without external high-voltage supplies.
It integrates a power-on reset (POR) circuit that prevents spurious writes during power-up, and uses open-drain SDA with external pull-up-requiring no internal level-shifting. The WC pin provides hardware-level write inhibit independent of I²C command flow, enabling robust system-level memory protection.
Key Specifications

Pinout & Package
Package: TSSOP8 (ECOPACK2), 169 mil width, lead-free, RoHS-compliant surface-mount package with 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDA) | Serial Data I/O | Open-drain bidirectional bus line; requires external pull-up; shares bus with other I²C slaves |
| 2 (VSS) | Ground | Reference return path for all internal circuits and I/O; must be low-impedance connection |
| 3 (SCL) | Serial Clock Input | Master-generated clock synchronizing all data transfers; edge-triggered sampling on rising edge |
| 4 (NC) | No Connect | Internally unconnected; must remain floating or tied to ground per layout best practice |
| 5 (NC) | No Connect | Internally unconnected; no electrical function; avoid routing signals beneath this pad |
| 6 (NC) | No Connect | Internally unconnected; not bonded; no thermal or mechanical role |
| 7 (VCC) | Supply Voltage | Power input for core and I/O; requires local 10–100 nF decoupling capacitor near pin |

Key Features
| Feature | Design Value |
|---|---|
| Hardware write protection (WC pin) | Enables system-level memory lockdown without software intervention-critical for safety-critical calibration data |
| Low-voltage operation (1.7 V min) | Permits direct integration with 1.8 V microcontrollers and battery-backed systems without level shifters |
| ECOPACK2 packaging | Meets RoHS and JEDEC J-STD-020D soldering standards; supports automated reflow and long-term reliability |

FAQ
What is the function of the WC pin on M24C16-FMN6TP?
The WC (Write Control) pin is an active-high hardware enable for write operations. When driven high, it disables all write instructions-including byte and page writes-regardless of I²C command content. This provides fail-safe memory protection independent of firmware execution, critical for safeguarding calibration or safety-critical data.
Can M24C16-FMN6TP operate reliably at 1.6 V?
No-M24C16-FMN6TP is specified for guaranteed operation from 1.7 V to 5.5 V across the full –40 °C to +85 °C range. Operation between 1.6 V and 1.7 V is permitted only under limited temperature conditions (0 °C to +70 °C for write, –20 °C to +70 °C for read), and is not recommended for new designs requiring full industrial qualification.
Does M24C16-FMN6TP require external pull-up resistors on SDA and SCL?
Yes-SDA and SCL are open-drain I/Os and require external pull-up resistors to VCC. The datasheet recommends calculating values based on bus capacitance and desired rise time; typical values range from 2.2 kΩ to 10 kΩ for standard-mode (100 kHz) and fast-mode (400 kHz) I²C buses with ≤100 pF load.
How many write cycles can M24C16-FMN6TP endure before failure?
M24C16-FMN6TP is characterized for more than 4 million write cycles at 25 °C and more than 1.2 million at 85 °C. Each byte or page write instruction counts as one cycle. This endurance supports daily rewrites for over 10 years in typical industrial applications, assuming conservative usage patterns and proper voltage/current margins.
