ST LRI2K

Overview

The LRI2K is a contactless memory powered by the received carrier electromagnetic wave. It is a 2048-bit electrically erasable programmable memory (EEPROM). The memory is organized as 64 blocks of 32 bits.

General Description:

The LRI2K is a contactless memory powered by the received carrier electromagnetic wave. It is a 2048-bit electrically erasable programmable memory (EEPROM). The memory is organized as 64 blocks of 32 bits. The LRI2K is accessed via the 13.56 MHz carrier electromagnetic wave on which incoming data are demodulated from the received signal amplitude modulation (ASK: amplitude shift keying). The received ASK wave is 10% or 100% modulated with a data rate of 1.6 Kbit/s using the 1/256 pulse coding mode or a data rate of 26 Kbit/s using the 1/4 pulse coding mode.

Technical Features:

  • Belongs to the ST25 family, that includes all STMicroelectronics NFC/RFID tag and reader products
  • ISO 15693 standard fully compliant
  • ISO 18000-3 Mode 1 standard fully compliant
  • 13.56 MHz ±7 kHz carrier frequency
  • To tag: 10% or 100% ASK modulation using 1/4 (26 Kbit/s) or 1/256 (1.6 Kbit/s) pulse position coding
  • From tag: load modulation using Manchester coding with 423 kHz and 484 kHz subcarriers in low (6.6 Kbit/s) or high (26 Kbit/s) data rate mode. Supports the 53 Kbit/s data rate with Fast commands
  • Internal tuning capacitor (21 pF or 97 pF)
  • 1 000 000 Erase/Write cycles (minimum)
  • 40 year data retention (minimum)
  • 2048 bits EEPROM with Block Lock feature
  • 64-bit unique identifier (UID)
  • Electrical article surveillance capable (software controlled)
