Product details
Overview
M24SR02-YMN6T/2 from STMicroelectronics is a dynamic NFC/RFID tag IC with dual I²C and contactless interfaces, embedding 2-Kbit EEPROM compliant with NFC Forum Type 4 Tag and ISO/IEC 14443 Type A. It operates from 2.7 V to 5.5 V, supports 1 MHz I²C, features 7-byte UID and 128-bit password protection, and enables secure NDEF data exchange in smart labels and IoT edge nodes.
For engineers reviewing the M24SR02-YMN6T/2 datasheet, M24SR02-YMN6T/2 pinout, M24SR02-YMN6T/2 application, or M24SR02-YMN6T/2 equivalent, this page delivers verified electrical specs, dual-interface timing behavior, GPO configuration modes, RF disable control, and real-world use cases in NFC-enabled industrial tagging and secure device onboarding.
Technical Context
The M24SR02-Y implements concurrent I²C slave and ISO/IEC 14443-A RF protocols, enabling synchronized access to shared 256-byte EEPROM memory across both interfaces. Its session token mechanism prevents race conditions during simultaneous I²C read and RF write operations.
It supports three functional modes: pure I²C mode (VCC-powered only), pure Tag mode (RF-powered only), and Dual Interface mode where RF commands can trigger I²C-initiated actions via GPO signaling - e.g., RF session open asserting GPO to wake host MCU.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| I²C Speed | Up to 1 MHz - enables fast host MCU firmware updates without blocking RF polling cycles. |
| RF Data Rate | 106 Kbps - ensures compatibility with all NFC Forum-certified readers and smartphones. |
| EEPROM Size | 256 bytes (2-kbit) - sufficient for full NDEF message storage including CC file, NDEF file, and system file. |
| Data Retention | 200 years at 25 °C - guarantees long-term integrity of calibration data or device identity in unpowered storage. |
| Write Endurance | 1 million cycles at 25 °C - supports frequent field-updatable parameters in asset tracking tags. |
| Operating Temp | –40 °C to +85 °C - validated for deployment in industrial enclosures and automotive under-hood environments. |
| Internal Tuning Cap | 25 pF - reduces external matching component count when integrating with printed antenna traces. |
Pinout & Package
Package: 8-lead TSSOP8 (ECOPACK2), also available in SO8 and UFDFPN8 variants. Pinout validated per DS9985 Rev 12 Section 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Supply voltage input | 2.7–5.5 V main power rail; powers I²C logic and internal RF regulator. |
| VSS | Ground reference | Common return path for I²C signals and RF coil bias current. |
| SCL | I²C clock input | Master-generated clock synchronizing bidirectional SDA transfers up to 1 MHz. |
| SDA | I²C bidirectional data line | Open-drain interface supporting standard and fast-mode I²C protocol handshaking. |
| AC0 / AC1 | RF antenna connection | Differential terminals for connecting 13.56 MHz LC tank; internal 25 pF tuning capacitance reduces BOM. |
| RF_DISABLE | Active-low RF enable control | Pulling low disables RF field detection and prevents unintended tag activation during I²C programming. |
| GPO | Configurable general-purpose output | Programmable as session status indicator, interrupt, or RF busy signal per GPO field settings (0x1X–0x6X). |
Key Features
| Feature | Design Value |
|---|---|
| NFC Forum Type 4 Tag compliance | Enables plug-and-play interoperability with Android/iOS NFC stacks without custom driver development. |
| Dual-interface session arbitration | Hardware-enforced token-based mutual exclusion prevents memory corruption during concurrent I²C/RF access. |
| 7-byte unique identifier (UID) | Factory-programmed immutable ID used for device authentication and anti-cloning in secure provisioning flows. |
| 128-bit password protection | Separate I²C and NDEF file passwords enforce layered access control - e.g., read-only NDEF for end users, full access for service technicians. |
| GPO configurable states | Eight distinct output behaviors (e.g., Session Open, WIP, INT) allow host MCU to monitor tag state without polling registers. |
Applications
| Smart Industrial Label | Secure Device Onboarding |
|---|---|
Use Scenario: Asset tag on factory floor equipment storing maintenance history, calibration date, and firmware version. IC Role / Device Role / Timing Role: Dual-interface EEPROM serving as persistent, field-updatable configuration store accessible via handheld NFC scanner or PLC-connected I²C bus.

Use Scenario: Wireless earbud case storing serial number, battery health, and firmware revision for quick diagnostics. IC Role / Device Role / Timing Role: Low-power EEPROM accessed via I²C during charging and exposed via RF when lid opens near phone. Use Value: Enables zero-touch support workflows - user taps case to pull diagnostics without Bluetooth pairing or app installation. |
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, no GPO, fixed RF_DISABLE behavior, lower max I²C speed (400 kHz) | Lacks session-aware GPO signaling and dual-mode coordination; suitable only for basic NFC data exchange | Select when cost sensitivity outweighs need for host-MCU synchronization and advanced access control. |
| M24SR64-YMN6T/2 | 64-Kbit EEPROM, identical pinout and command set, same temperature range and packaging | Supports larger NDEF payloads (e.g., firmware fragments, multi-language UI strings) but higher unit cost | Choose when >256-byte NDEF capacity is required - e.g., for OTA update metadata or multi-region configuration sets. |
Compared with NT3H2111W0FHKH, M24SR02-YMN6T/2 offers superior host coordination via GPO and faster I²C; versus M24SR64-YMN6T/2, it trades density for lower cost and power in space-constrained tags where 2-Kbit suffices.

FAQ
What is the maximum I²C clock frequency supported by M24SR02-YMN6T/2?
The device supports I²C Fast Mode Plus operation up to 1 MHz, confirmed in DS9985 Rev 12 Section 11. This allows high-throughput host MCU writes to EEPROM while maintaining compatibility with standard I²C controllers. Timing margins meet I²C specification requirements down to 2.7 V supply.
Can the RF interface operate without external power (VCC disconnected)?
Yes - in pure Tag mode, the device draws power solely from the 13.56 MHz RF field via AC0/AC1 pins, enabling passive operation. However, I²C functionality and GPO output require VCC; RF_DISABLE must be pulled high to enable field harvesting in this configuration.
How is memory access protected between I²C and RF interfaces?
Access is controlled by separate 128-bit passwords for I²C and NDEF files, plus hardware-enforced session tokens. The RF_DISABLE pin provides physical layer isolation, and the GPO can signal active RF sessions to prevent conflicting I²C writes during tag interrogation.
Does M24SR02-YMN6T/2 support ISO/IEC 14443 Type B or FeliCa protocols?
No - it is strictly compliant with ISO/IEC 14443 Type A and NFC Forum Type 4 Tag specifications only. Type B and FeliCa are not implemented in silicon; attempting to communicate using those protocols results in no response or invalid frame rejection.
