Product details

Overview

M24SR16-YDW6T/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 2.7–5.5 V supply. It enables secure NDEF data exchange in smart labels, asset tagging, and industrial IoT edge nodes where battery-free RF read/write and host-controlled memory access coexist.

For engineers reviewing the M24SR16-YDW6T/2 datasheet, M24SR16-YDW6T/2 pinout, M24SR16-YDW6T/2 application, or M24SR16-YDW6T/2 equivalent, key selection criteria include I²C slave timing at 1 MHz, UID uniqueness (7-byte), EEPROM endurance (1M cycles @25°C), RF disable control, and GPO configurability for session signaling or interrupt indication.

Technical Context

The device operates in three functional modes: I²C mode (host-controlled memory access), Tag mode (NFC reader-initiated NDEF exchange), and Dual Interface mode (coordinated access with session token arbitration). Its I²C interface behaves strictly as a slave with fixed 7-bit address (0x50) and supports standard/fast-mode timing up to 1 MHz.

RF communication follows NFC Forum Type 4 Tag protocol with ISO/IEC 14443 Type A physical layer, 106 Kbps data rate, and built-in 25 pF tuning capacitance. Memory management enforces NDEF file structure with CC (Capability Container), NDEF, and System files, plus password-protected access rights and permanent state locking via proprietary commands.

Key Specifications

Parameter	Value and Actual Design Meaning
I²C interface speed	Up to 1 MHz - enables high-throughput host-side memory updates without CPU polling overhead.
EEPROM capacity	16-Kbit (2-Kbyte) - stores full NDEF messages, capability container, system metadata, and passwords in standardized layout.
Data retention	200 years @25°C - ensures long-term integrity of firmware tags, calibration data, or device identity in unpowered storage.
Write endurance	1 million cycles @25°C - supports frequent field reprogramming in logistics or maintenance applications.
RF protocol	NFC Forum Type 4 Tag / ISO/IEC 14443 Type A - guarantees interoperability with all certified NFC smartphones and readers.
Unique identifier	7-byte UID - provides cryptographically verifiable device identity for anti-cloning and secure pairing.
Supply voltage	2.7 V to 5.5 V - compatible with industrial 3.3 V and legacy 5 V microcontroller buses without level-shifting.

Pinout & Package

Package: UFDFPN8 ECOPACK2® (2.0 × 2.0 mm, 0.4 mm pitch, exposed pad). 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 for digital and RF sections; exposed pad must be soldered for thermal and EMI performance.
SCL	I²C clock input	Master-generated clock synchronizes all I²C transactions; supports clock stretching during EEPROM write.
SDA	I²C bidirectional data	Open-drain line shared by host and device; requires external pull-up (1–10 kΩ) to VCC.
AC0 / AC1	RF antenna connection	Differential inputs for 13.56 MHz loop antenna; internal 25 pF tuning reduces external component count.
RF_DISABLE	RF interface enable control	Active-low signal disables RF detection and response-critical for EMI-sensitive environments or power gating.
GPO	Configurable general-purpose output	Programmable as session-open flag, WIP indicator, NDEF write progress, or interrupt source per GPO field settings.

Key Features

Feature	Design Value
Dual-interface session arbitration	Hardware-enforced token-based mutual exclusion prevents I²C/RF memory conflicts during concurrent access.
NDEF-compliant memory layout	Predefined CC, NDEF, and System files simplify NFC smartphone integration without custom firmware parsing.
Password-protected access control	Separate 128-bit passwords for NDEF read/write and I²C access enable layered security in multi-role systems.
Permanent state locking	EnablePermanentState command makes NDEF files immutable-used for firmware version stamps or calibrated sensor offsets.
Configurable GPO signaling	Seven GPO modes (e.g., RF busy, I²C answer ready) reduce host polling and accelerate system-level event handling.

Applications

Smart Industrial Labels

Secure Device Authentication

Use Scenario: Asset tags on factory floor equipment store maintenance logs, calibration dates, and firmware versions accessible via NFC phone or PLC-connected I²C host.

IC Role / Device Role / Timing Role: Dual-interface tag IC providing battery-free RF readout and deterministic I²C update path synchronized to production line controller timing.

Use Value: Eliminates manual barcode scanning; enables real-time traceability with tamper-evident NDEF writes and UID-anchored audit trails.

Use Scenario: Embedded in medical sensors to bind unique hardware ID, cryptographic keys, and usage counters to prevent cloning or unauthorized reuse.

IC Role / Device Role / Timing Role: Secure identity anchor with password-gated NDEF writes and permanent state locking for critical parameters.

Use Value: Meets IEC 62304 requirements for device identity integrity; UID + 128-bit passwords provide foundational trust for TLS handshake bootstrapping.

Interactive Consumer Packaging

IoT Edge Node Configuration

Use Scenario: NFC-enabled product packaging delivers marketing content, warranty registration, and multilingual instructions when tapped by consumer smartphones.

IC Role / Device Role / Timing Role: NFC Forum Type 4 Tag IC operating in passive Tag mode; responds within 106 Kbps timing budget to mobile reader commands.

Use Value: Zero-power operation extends shelf life; standardized NDEF format ensures compatibility across Android/iOS NFC stacks without app installation.

Use Scenario: Gateway devices use M24SR16-Y to store network credentials, OTA update signatures, and sensor calibration profiles updated over I²C during manufacturing or field service.

IC Role / Device Role / Timing Role: Trusted configuration vault with I²C write endurance (1M cycles) and RF read-only access for diagnostics.

Use Value: Decouples sensitive provisioning from main MCU firmware; enables secure credential injection without exposing keys to host software stack.

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 RF frontend, no I²C interface - single-interface only.	Lacks dual-interface capability; suitable only for pure NFC reader interaction, not host-controlled updates.	Select when cost and footprint are prioritized over host-side programmability and session coordination.
M24SR64-YDW6T/2	64-Kbit EEPROM, identical pinout/package, same dual-interface architecture and command set.	Higher memory capacity supports larger NDEF payloads (e.g., firmware images, multi-language content).	Choose for applications requiring >2-Kbyte NDEF storage while maintaining identical integration effort and timing behavior.

Compared with NT3H2111W0FHKH, M24SR16-YDW6T/2 adds deterministic I²C control and session arbitration; compared with M24SR64-YDW6T/2, it trades memory depth for lower unit cost and reduced write latency in constrained-edge deployments.

FAQ

What is the maximum I²C clock frequency supported by M24SR16-YDW6T/2?

The device supports I²C communication up to 1 MHz in standard and fast-mode protocols. This is confirmed in Section 11 of the official datasheet (DocID024755 Rev 9), with AC timing parameters validated across the full -40°C to +85°C temperature range and 2.7–5.5 V supply.

Does M24SR16-YDW6T/2 require external tuning capacitors for the RF interface?

No. The IC integrates 25 pF internal tuning capacitance across AC0/AC1 pins, eliminating the need for external capacitors in most 13.56 MHz antenna designs. Antenna matching remains necessary, but the internal capacitance simplifies layout and improves consistency across production units.

How is memory access protected against unauthorized writes?

Access protection uses two independent 128-bit password mechanisms: one for NDEF file read/write operations (verified via ISO/IEC 7816-4 Verify command), and another for I²C interface access (enforced by the I²C Protect field in the System file). Both passwords are stored in encrypted form within the EEPROM.

Can M24SR16-YDW6T/2 operate in environments exceeding 85°C?

No. The specified operating temperature range is -40°C to +85°C. At 85°C, write endurance is derated to 600k cycles, and data retention drops below 200 years. Operation beyond 85°C risks parametric failure, EEPROM corruption, and noncompliance with NFC Forum Type 4 timing requirements.
