Product details
Overview
M24SR04-YMN6T/2 from STMicroelectronics is a dynamic NFC/RFID tag IC with dual I²C and contactless interfaces, compliant with NFC Forum Type 4 Tag and ISO/IEC 14443 Type A standards. It integrates 4-Kbit EEPROM (512 bytes), supports 1 MHz I²C, operates from 2.7 V to 5.5 V, and delivers 200-year data retention - deployed in secure product authentication, smart packaging, and industrial asset tagging.
For engineers reviewing the M24SR04-YMN6T/2 datasheet, M24SR04-YMN6T/2 pinout, M24SR04-YMN6T/2 application, or M24SR04-YMN6T/2 equivalent, this page provides verified functional modes (I²C mode, Tag mode, Dual interface mode), confirmed memory architecture (NDEF-compliant file system), validated GPO configurations (Session Open, RF Busy, INT), and exact package mapping to TSSOP8 (DW variant).
Technical Context
The device implements a true dual-interface architecture: I²C slave operation at up to 1 MHz coexists with ISO/IEC 14443-A RF communication at 106 Kbps, enabling synchronized read/write access across wired and wireless domains. Its session token mechanism (I²C token and RF token) enforces mutual exclusion between interfaces to prevent memory corruption.
Memory management follows NFC Forum Type 4 Tag specifications, with dedicated Capability Container (CC) and NDEF files, plus a System file containing UID (7-byte), passwords (128-bit), and configuration fields (RF enable, GPO mode). The internal 25 pF tuning capacitance eliminates need for external RF matching components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Interface | Dual: I²C slave + ISO/IEC 14443-A RF - enables simultaneous host MCU control and NFC phone interaction without arbitration logic. |
| Memory | 4-Kbit (512-byte) EEPROM - stores NDEF messages with full NDEF file layout support (CC, NDEF, System files). |
| Data Retention | 200 years at 25 °C - ensures long-term integrity of firmware signatures or calibration data in unpowered deployments. |
| Write Endurance | 1 million cycles at 25 °C - sufficient for frequent field-updatable parameters in IoT edge nodes. |
| Operating Voltage | 2.7 V to 5.5 V - compatible with 3.3 V and 5 V microcontroller I/O rails without level-shifting. |
| Temperature Range | −40 °C to +85 °C - qualified for industrial automation and automotive under-hood accessory tagging. |
| RF Data Rate | 106 Kbps - matches standard NFC reader throughput for fast tag enumeration in retail kiosks. |
Pinout & Package
Package: TSSOP8 (ECOPACK2®), 3.0 mm × 4.4 mm body, 0.65 mm pitch - surface-mount compatible with automated PCB assembly and space-constrained modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Accepts 2.7–5.5 V; powers both I²C logic and RF front-end; decoupling capacitor required per datasheet Section 10. |
| VSS | Ground reference | Common return for digital and RF sections; must be low-impedance connection to minimize noise coupling into antenna path. |
| SCL | I²C clock input | Master-generated clock; supports up to 1 MHz; open-drain requires external pull-up resistor (typically 2.2 kΩ). |
| SDA | I²C bidirectional data | Open-drain I/O; shares bus with other I²C slaves; ACK/NACK timing defined in Section 7.6 of datasheet. |
| AC0 / AC1 | RF antenna connection | Differential RF port for 13.56 MHz loop antenna; internal 25 pF tuning capacitance reduces BOM count and layout sensitivity. |
| GPO | Configurable general-purpose output | Programmable as Session Open flag, RF Busy indicator, or interrupt signal - enables hardware handshaking with host MCU. |
| RF Disable | RF interface enable/disable control | Active-low input; disables RF receiver when asserted, eliminating unintended tag activation in EMI-sensitive environments. |
Key Features
| Feature | Design Value |
|---|---|
| NFC Forum Type 4 Tag compliance | Full implementation of ISO/IEC 14443-A and NFC Forum specifications - ensures interoperability with Android NFC stacks and commercial readers. |
| Secure NDEF file access | 128-bit password protection for NDEF files and separate I²C password - prevents unauthorized writes during production or field service. |
| Hardware session arbitration | Dedicated I²C and RF tokens enforce exclusive memory access - eliminates software-level locking complexity in dual-interface applications. |
| Single-command bulk transfer | Read/write up to 246 bytes in one I²C or RF command - reduces transaction overhead for firmware updates or sensor log uploads. |
| Configurable GPO signaling | 7 distinct GPO modes (e.g., Session Open, WIP, INT) - enables real-time status feedback to host without polling, lowering CPU load. |

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-Kbit EEPROM, integrated 13.56 MHz antenna matching network, no I²C interface - RF-only operation. | Requires external MCU for data processing; unsuitable for dual-interface synchronization use cases. | Select when cost-sensitive, single-interface NFC functionality suffices and board space permits antenna integration. |
| M24SR64-YMN6T/2 | 64-Kbit EEPROM (8-Kbyte), identical pinout and protocol stack - direct memory upgrade path. | Same footprint and software API; supports larger NDEF payloads (e.g., multi-language manuals, firmware images). | Choose for future-proofing where memory scalability is prioritized over minimal BOM cost. |
Compared with NT3H2111W0FHKH, M24SR04-YMN6T/2 adds deterministic I²C control and higher endurance; versus M24SR64-YMN6T/2, it trades memory depth for lower unit cost and reduced power during RF-only reads.

FAQ
What is the maximum I²C clock frequency supported by M24SR04-YMN6T/2?
The device supports I²C communication up to 1 MHz, as specified in Section 11 of the datasheet. This high-speed mode enables rapid bulk transfers (up to 246 bytes per command) and reduces host MCU wait time during memory access - critical for real-time industrial diagnostics.
Does M24SR04-YMN6T/2 require external tuning capacitors for the RF interface?
No. The IC integrates 25 pF internal tuning capacitance (Section 14, RF electrical parameters), eliminating the need for external capacitors in most antenna designs. This simplifies layout, reduces BOM count, and improves RF performance consistency across manufacturing lots.
How is memory access protected against unauthorized writes?
Two independent password mechanisms are implemented: a 128-bit NDEF file password (Section 3.4) and a separate I²C password (Section 3.5). Both must be verified before write operations, and passwords can be permanently locked via EnablePermanentState command (Section 5.8.2).
Can M24SR04-YMN6T/2 operate without a VCC supply when accessed via NFC?
Yes. In RF-only mode, the device draws power entirely from the 13.56 MHz magnetic field (Section 6.1). VCC is only required for I²C operation or when GPO is used as an active output - enabling true zero-power NFC interaction in battery-free applications.
