Product details
Overview
ANT1-M24LR-A from STMicroelectronics is a ready-to-use 45 mm × 75 mm reference evaluation board for the M24LR64-R dual-interface EEPROM, integrating a 13.56 MHz inductive antenna and an I²C connector. It enables RF and I²C interface evaluation of the M24LR64-R IC in NFC/RFID tag applications with passive RF coupling and wired memory access.
For engineers reviewing the ANT1-M24LR-A datasheet, ANT1-M24LR-A pinout, ANT1-M24LR-A application, or ANT1-M24LR-A equivalent, this board supports rapid prototyping of dual-interface EEPROM systems requiring ISO/IEC 15693-compliant RF communication and standard I²C host integration.
Technical Context
The board implements a planar printed loop antenna tuned to 13.56 MHz with impedance matching optimized for the M24LR64-R's RF front-end. Antenna geometry (45 mm × 75 mm) delivers typical read range up to 50 cm with compliant readers under ISO/IEC 15693 Mode 1.
On the digital side, the M24LR64-R connects directly to a 4-pin I²C header (VDD, GND, SCL, SDA), supporting standard-mode (100 kHz) and fast-mode (400 kHz) operation. No external pull-ups or level shifters are required for basic evaluation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Board Dimensions | 45 mm × 75 mm - matches mechanical envelope for integration into compact NFC tag carriers or industrial label designs. |
| Antenna Frequency | 13.56 MHz - certified for ISO/IEC 15693 and NFC Forum Tag Type 5 operation with passive RF powering. |
| Antenna Type | Etched PCB loop - eliminates discrete coil assembly; provides repeatable Q-factor and coupling efficiency across units. |
| I²C Interface | 4-pin header (VDD, GND, SCL, SDA) - enables direct connection to microcontroller development platforms without adapter wiring. |
| Target IC | M24LR64-R - 64-Kbit dual-interface EEPROM with 13.56 MHz RF + I²C, supporting RF write and I²C read/write simultaneously. |

FAQ
Does ANT1-M24LR-A include the M24LR64-R IC pre-soldered?
Yes. The ANT1-M24LR-A board ships with the M24LR64-R dual-interface EEPROM IC fully assembled and soldered. No additional component placement or rework is needed to begin RF or I²C evaluation.
Can the antenna be modified or retuned for different read distances?
The etched antenna is fixed and optimized for 13.56 MHz operation with the M24LR64-R. Retuning requires Gerber file modification and re-fabrication; ST does not provide tuning components or adjustable matching networks on this reference board.
Is firmware or driver software included with the board?
No. ANT1-M24LR-A is a hardware-only reference board. ST provides application notes (AN4213, AN4322) and sample I²C initialization code, but no bundled drivers, GUI tools, or RF protocol stacks.
What is the maximum data transfer rate over the RF interface?
The M24LR64-R on ANT1-M24LR-A supports ISO/IEC 15693 Mode 1 at 26.48 kbit/s (1-out-of-4 coding). Actual throughput depends on reader capability, field strength, and command overhead-not board-level limitation.
