Product details
Overview
M24SR16-YMC6T/2 from STMicroelectronics is a dynamic NFC/RFID tag IC with dual-interface operation (I²C + contactless), 16-Kbit EEPROM, NFC Forum Type 4 Tag compliance, ISO/IEC 14443 Type A support, and 1 MHz I²C interface - deployed in secure smart labels for industrial asset tagging and NFC-enabled IoT sensor nodes.
For engineers reviewing the M24SR16-YMC6T/2 datasheet, M24SR16-YMC6T/2 pinout, M24SR16-YMC6T/2 application, or M24SR16-YMC6T/2 equivalent, key selection criteria include dual-interface session arbitration, NDEF file password protection, UID-based authentication, and GPO-configurable RF busy/interrupt signaling under -40°C to +85°C operation.
Technical Context
The device implements concurrent I²C slave and ISO/IEC 14443-A RF tag functionality with hardware-level session token management to prevent interface conflict. It supports full NFC Forum Type 4 Tag protocol stack including CC file, NDEF message handling, and system file access control.
Memory is organized into dedicated NDEF, Capability Container, and System files with configurable read/write access rights enforced via 128-bit passwords and I²C protect field. GPO output provides real-time status feedback (e.g., RF busy, I²C answer ready, WIP) without host polling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory capacity | 16-Kbit (2-Kbyte) EEPROM with 200-year data retention and 1M write cycles at 25°C - enables long-life firmware/data logging in unpowered deployments. |
| I²C interface | Two-wire slave interface supporting up to 1 MHz clock rate - allows high-speed host MCU integration without timing bottlenecks. |
| RF interface | NFC Forum Type 4 Tag compliant, ISO/IEC 14443 Type A, 106 Kbps data rate - ensures interoperability with all standard NFC readers and smartphones. |
| Supply voltage | 2.7 V to 5.5 V single supply - simplifies power design across battery-powered and industrial 3.3 V/5 V systems. |
| Operating temperature | -40 °C to +85 °C - qualified for automotive interior, industrial control panels, and outdoor smart infrastructure. |
| Unique identifier | 7-byte UID factory-programmed - provides immutable device identity for secure provisioning and anti-cloning. |
| Security features | 128-bit NDEF file passwords, I²C password protection, and permanent state locking - enforces multi-layer access control for sensitive configuration data. |
Pinout & Package
Package: 8-lead TSSOP8 (ECOPACK2®), footprint-compatible with SO8 and UFDFPN8 variants. Pin assignment validated per STMicroelectronics DocID024755 Rev 9, Section 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Single 2.7–5.5 V rail powers both I²C logic and RF front-end; internal LDO not required. |
| VSS | Ground reference | Common return path for digital and RF sections; decoupling capacitor placement critical for RF stability. |
| SCL | I²C clock input | Master-generated clock synchronizes bidirectional SDA transfers; supports standard/fast-mode plus 1 MHz high-speed mode. |
| SDA | I²C bidirectional data line | Open-drain interface with internal pull-up; handles command/response framing for memory reads/writes and system control. |
| AC0 / AC1 | RF antenna connection | Differential RF port for external 13.56 MHz loop antenna; internal 25 pF tuning capacitance reduces external component count. |
| RF_DISABLE | RF interface enable/disable control | Active-low signal disables RF detection and communication - used for EMI mitigation or deterministic I²C-only operation. |
| GPO | Configurable general-purpose output | Programmable as RF busy indicator, I²C answer ready flag, or interrupt source - eliminates polling overhead in host firmware. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-interface session arbitration | Hardware-managed I²C/RF token exchange prevents bus contention and ensures atomic memory updates across interfaces. |
| NDEF messaging support | Native CC file and NDEF file layout per NFC Forum specification - enables plug-and-play compatibility with Android/iOS NFC apps. |
| Configurable GPO signaling | Seven GPO modes (e.g., RF busy, WIP, INT) mapped via System File register - delivers real-time event notification without host polling. |
| Secure memory partitioning | Separate read/write access rights per NDEF file, enforced by 128-bit passwords and I²C protect bit - isolates sensitive configuration from user data. |
| Permanent state locking | EnablePermanentState command locks System File fields (e.g., UID, passwords) against future modification - prevents tampering after provisioning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dynamic NFC tag applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NT3H2111W0FHKH | 1-Kbyte EEPROM, integrated 13.56 MHz antenna matching network, no I²C interface - RF-only operation. | Lacks dual-interface capability; suited for passive NFC stickers, not host-controlled systems. | Select when cost-sensitive, single-interface NFC labeling suffices and host MCU integration is unnecessary. |
| M24SR64-YMC6T/2 | 64-Kbit EEPROM, identical pinout and feature set - direct memory upgrade within same package and software stack. | Same dual-interface behavior and security model; higher memory supports larger NDEF payloads or multiple application files. | Select when >16 Kbit NDEF storage is required for complex configuration sets or firmware metadata without changing PCB or firmware architecture. |
Compared with NT3H2111W0FHKH, M24SR16-YMC6T/2 adds deterministic I²C control and session arbitration for host-managed NFC operations; compared with M24SR64-YMC6T/2, it trades memory density for lower unit cost while maintaining identical security, timing, and thermal specifications.

FAQ
What is the maximum I²C clock frequency supported by M24SR16-YMC6T/2?
The device supports I²C operation up to 1 MHz in high-speed mode, as specified in Section 11 of the official datasheet (DocID024755 Rev 9). This enables fast memory access during host MCU initialization or bulk NDEF updates without compromising timing margins.
How does the GPO pin function in RF busy mode?
When configured as RF busy (GPO field = 0x6X), the GPO pin asserts high during active RF communication and returns low upon completion - providing hardware-level synchronization for host MCU to delay I²C commands until RF session concludes.
Can the UID be modified after factory programming?
No. The 7-byte UID is laser-trimmed during wafer test and permanently stored in ROM. It cannot be altered, erased, or rewritten - ensuring immutable device identity for authentication and anti-counterfeiting use cases.
Is external antenna tuning required for reliable 13.56 MHz operation?
No. The device integrates 25 pF internal tuning capacitance across AC0/AC1 pins, enabling functional operation with a simple printed loop antenna. External matching components are optional and only needed for marginal antenna designs or regulatory optimization.
