Description
M24SR04 belongs to the ST25 family which
includes all STMicroelectronics NFC/RFID tag and
reader products.
The M24SR04 devices is a dynamic NFC/RFID
tag IC with a dual interface. It embeds an
EEPROM memory. It can be operated from an I2C
interface or by a 13.56 MHz RFID reader or an
NFC phone.
The I2C interface uses a two-wire serial interface,
consisting of a bidirectional data
line. It behaves as a slave in the
lIi2nCe
and a clock
protocol.
The RF protocol is compatible with ISO/IEC
14443 Type A and NFC Forum Type 4 Tag.
1. Limited temperature range -25 to 85 °C
2. Preliminary data for automotive grade (under
qualification).
3. Package for automotive grade.
