Product details
Overview
M24SR04-YMC6T/2 from STMicroelectronics is a dynamic NFC/RFID tag IC with dual I²C and contactless interfaces, implementing NFC Forum Type 4 Tag and ISO/IEC 14443 Type A protocols. It integrates 4-Kbit EEPROM (512 bytes), supports 1 MHz I²C, operates from 2.7 V to 5.5 V, and features 7-byte UID and 128-bit password protection - deployed in secure product authentication and smart packaging systems.
For engineers reviewing the M24SR04-YMC6T/2 datasheet, M24SR04-YMC6T/2 pinout, M24SR04-YMC6T/2 application, or M24SR04-YMC6T/2 equivalent, key selection criteria include dual-interface session coordination, NDEF message handling capability, RF disable control, GPO programmability for status signaling, and EEPROM endurance at elevated temperature (600k write cycles @ 85 °C).
Technical Context
The device operates in three functional modes: I²C mode (as slave), Tag mode (RF-initiated), and Dual Interface mode where concurrent or coordinated access is managed via session tokens (I²C token and RF token). Memory access is governed by configurable read/write permissions per NDEF file, enforced through ISO/IEC 7816-4 Verify and Change Reference Data commands.
RF interface uses 13.56 MHz carrier with internal 25 pF tuning capacitance and supports 106 Kbps data rate; I²C interface complies with standard two-wire protocol including ACK/NACK, start/stop conditions, and timeout detection on clock stretch. GPO output supports seven configurable states including RF busy, I²C answer ready, and interrupt assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| I²C Speed | Up to 1 MHz - enables high-throughput host MCU communication without bus contention in embedded controllers. |
| EEPROM Size | 4-Kbit (512 bytes) - sufficient for full NDEF records including URI, text, or smart poster payloads with CC and system files. |
| Data Retention | 200 years @ 25 °C - ensures long-term integrity of firmware signatures or calibration data in industrial deployments. |
| Write Endurance | 1 million cycles @ 25 °C; 600k @ 85 °C - supports frequent reprogramming in thermal cycling environments like automotive cabin modules. |
| NFC Compliance | NFC Forum Type 4 Tag + ISO/IEC 14443 Type A - guarantees interoperability with Android NFC stacks and commercial readers. |
| Supply Voltage | 2.7 V to 5.5 V - compatible with 3.3 V and 5 V microcontroller I/O domains without level-shifting. |
| UID Length | 7 bytes - provides globally unique identification for anti-cloning and supply chain traceability applications. |
Pinout & Package
Package: 8-lead TSSOP8 (ECOPACK2®), body size 3.0 × 4.4 mm, 0.65 mm pitch - optimized for space-constrained PCBs in wearables and IoT edge nodes.
| 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; no separate analog/digital supplies required. |
| VSS | Ground reference | Common return path for digital and RF sections; requires low-inductance connection to minimize noise coupling. |
| SCL | I²C clock input | Master-generated clock synchronizes bidirectional SDA transfers; supports standard/fast-mode timing. |
| SDA | I²C bidirectional data line | Open-drain interface with external pull-up; handles command/response framing per I²C specification. |
| AC0 / AC1 | RF antenna connection | Differential terminals for 13.56 MHz LC tank; internal 25 pF tuning reduces external component count. |
| GPO | Configurable general-purpose output | Programmable as RF busy flag, I²C ready signal, or interrupt - eliminates need for external GPIO polling. |
| RF Disable | RF interface enable/disable control | Active-low input disables RF field detection and response - critical for EMI-sensitive medical or automotive subsystems. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-interface session arbitration | Hardware-enforced token-based mutual exclusion prevents memory corruption during concurrent I²C and RF access. |
| NDEF-compliant memory layout | Predefined CC file, NDEF file, and system file structure simplifies Android Beam and NFC reader integration. |
| Password-protected memory zones | 128-bit I²C and NDEF file passwords enable tiered access control for OEM firmware vs. end-user data. |
| Configurable GPO states | Seven GPO configurations (e.g., RF busy, WIP, INT) reduce host software overhead in real-time status monitoring. |
| RF disable pin | Hardware-level RF shutdown meets EN 55032 Class B radiated emission requirements without firmware intervention. |
Applications
| Smart Product Authentication | Industrial Equipment Tagging |
|---|---|
|
Use Scenario: Embedded in tamper-evident labels on medical devices to verify genuine components during service. IC Role / Device Role / Timing Role: Stores digitally signed firmware hash and serial number; responds to NFC phone queries with cryptographically verifiable data.

| Secure Access Control Cards | IoT Sensor Node Configuration |
|
Use Scenario: Integrated into employee ID badges supporting both physical door access and logical system login via NFC handshake. IC Role / Device Role / Timing Role: Hosts NDEF-formatted credentials readable by access panels; I²C interface allows IT admins to remotely refresh keys via connected gateway.

Use Scenario: Attached to environmental sensor modules to store calibration coefficients and network credentials updated during manufacturing test. IC Role / Device Role / Timing Role: Provides nonvolatile storage for sensor-specific parameters; GPO signals "config ready" to host MCU after I²C write completion. Use Value: Eliminates boot-time EEPROM initialization delays - host reads calibrated values immediately upon power-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dynamic NFC tag applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXH3670UK/V1 | Integrated NFC antenna driver + 2-Kbit EEPROM; no I²C interface; supports only RF-initiated access. | Limited to pure NFC reader interaction; unsuitable for host-controlled configuration or dual-interface synchronization. | Select when system architecture relies solely on NFC polling and does not require MCU-side memory management. |
| NT3H2111W0FHKH | 1-Kbyte EEPROM; supports I²C up to 400 kHz; lacks GPO and RF disable pin; lower write endurance (100k cycles @ 85 °C). | Lower memory capacity and no hardware RF disable limit use in high-security or thermally demanding environments. | Choose for cost-sensitive consumer electronics where full 4-Kbit NDEF support and industrial-grade endurance are not required. |
Compared with NXH3670UK/V1 and NT3H2111W0FHKH, M24SR04-YMC6T/2 uniquely delivers synchronized dual-interface operation, hardware session arbitration, and industrial-grade EEPROM reliability - making it the only option for applications requiring concurrent NFC interrogation and MCU-driven configuration updates under thermal stress.

FAQ
What is the maximum I²C clock frequency supported by M24SR04-YMC6T/2?
The device supports I²C up to 1 MHz in fast-mode plus, verified per ST's datasheet DocID024754 Rev 16 Section 11. This enables efficient bulk NDEF record transfers without introducing bus latency in real-time embedded systems.
Does M24SR04-YMC6T/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 - reducing BOM count and PCB area in compact form factors.
How is memory write protection implemented on M24SR04-YMC6T/2?
Protection uses 128-bit passwords for both I²C and NDEF file access, plus configurable read/write rights per file (Section 3.2). Passwords are stored in the system file and enforced by hardware - no software-only lock mechanisms.
Can M24SR04-YMC6T/2 operate in environments exceeding 85 °C?
No. The Y-grade device is rated for –40 °C to +85 °C (Section 10, Maximum ratings). At 85 °C, write endurance drops to 600k cycles; operation beyond this range risks parametric failure and violates ST's qualified operating conditions.
