Product details

Overview

M24SR64-YMN6T/2 from STMicroelectronics is a dynamic NFC/RFID tag IC with dual I²C and contactless interfaces, embedding 64-Kbit EEPROM memory compliant with NFC Forum Type 4 Tag and ISO/IEC 14443 Type A standards. It operates from 2.7 V to 5.5 V, supports 1 MHz I²C, and delivers 246-byte read/write bursts. Used in secure product authentication, smart packaging, and industrial asset tagging where NFC-enabled field access and local microcontroller control coexist.

For engineers reviewing the M24SR64-YMN6T/2 datasheet, M24SR64-YMN6T/2 pinout, M24SR64-YMN6T/2 application, or M24SR64-YMN6T/2 equivalent, key selection criteria include dual-interface session arbitration, UID-based device identity, NDEF structure support, RF disable control, and GPO-configurable status signaling for system-level event notification.

Technical Context

The device implements concurrent I²C slave and NFC Forum Type 4 Tag operation modes, with hardware-enforced session arbitration preventing simultaneous RF and I²C access to memory. Its RF interface uses ISO/IEC 14443 Type A at 106 Kbps and includes internal 25 pF tuning capacitance for simplified antenna design.

I²C communication follows standard two-wire protocol with configurable slave address (0x50–0x57), 1 MHz max clock rate, and built-in timeout protection. The GPO terminal supports seven programmable states-including RF busy, I²C answer ready, and WIP indication-enabling real-time host coordination without polling.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dynamic NFC tag applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NT3H2211W0FHKH	1-Kbyte EEPROM, no I²C interface; RF-only with integrated NFC antenna driver	Limited to pure reader-initiated use cases; lacks local microcontroller update capability	Select when cost-sensitive, single-interface NFC tagging suffices and local write control is unnecessary
M24SR04-YMN6T/2	4-Kbit EEPROM (vs. 64-Kbit); identical pinout, I²C/RF architecture, and feature set	Lower memory density suits simple ID storage but cannot host multi-record NDEF applications	Choose for space-constrained designs requiring same footprint and software compatibility with reduced data capacity needs

Compared with NT3H2211W0FHKH and M24SR04-YMN6T/2, the M24SR64-YMN6T/2 uniquely balances large NDEF-capable memory, full dual-interface control, and extended temperature RF operation - making it optimal for field-updatable, security-critical embedded tagging.

FAQ

What is the maximum I²C clock frequency supported by M24SR64-YMN6T/2?

The M24SR64-YMN6T/2 supports I²C communication up to 1 MHz in fast-mode plus, as confirmed in Section 11 of the official datasheet. This allows efficient bulk memory transfers while maintaining compatibility with standard I²C controllers without requiring custom timing adjustments.

Does M24SR64-YMN6T/2 require external tuning capacitors for its RF interface?

No. The device integrates 25 pF internal tuning capacitance across AC0/AC1 pins, eliminating the need for external capacitors in most antenna designs. This simplifies PCB layout and improves RF consistency across manufacturing batches, as specified in Section 14 of the datasheet.

How does the GPO pin function in M24SR64-YMN6T/2?

The GPO pin is programmable via I²C to signal seven distinct operational states - including RF busy, I²C answer ready, and write-in-progress - enabling interrupt-driven host coordination. Configuration is performed through the GPO field in the System file, detailed in Section 2.7 of the datasheet.

Can M24SR64-YMN6T/2 operate in RF mode at 105 °C?

No. RF operation is rated from −40 °C to +85 °C, while I²C operation extends to +105 °C. This thermal split reflects RF analog circuit limitations; attempting RF communication above 85 °C may result in failed anticollision or reduced coupling efficiency, as defined in Section 10 of the datasheet.
