NFC Tag IP for Proximity Integrated Circuit Cards (PICC) and Vicinity Integrated Circuit Cards (VICC)

Overview

Connectivity Solutions With Our NFC Tag IP in 22 nm CMOS

Our state-of-the-art NFC tag IP integrates seamlessly with ISO 14443-A, 14443-B, and 15693 standards. Ideal for both battery-less and battery-operated devices, this technology ensures best-in-class performance and versatility.

Building Blocks of CSEM’s NFC Tag IP

  • Analog Front-End
    • Energy efficient communication handling (RX, TX and clock recovery, CKR)–Energy harvesting (WPT) to power the system.
    • Fully compatible with all three ISO standards with four dedicated pads (two antenna pads, optional VDDR/VSSR)
  • Digital Baseband
    • Configurable soft IP supporting ISO 14443A, ISO 14443B, or ISO 15693.
    • Dual modes: Autonomous mode for independent NFC command handling, and microcontroller mode for streamlined NFC functionality
