R14AB

ISO 14443 Reader Chip Optimized for Battery-Powered RFID Readers

The R14AB is an extremely low-power ISO 14443A/B RFID reader IC. It also supports NFCIP-1 106-kbps active communication and Mifare® Ultralight 4-bit ACK/NACK reply. Other standards and custom protocols are possible via the transparent mode.
A complete development kit including a R14AB reader board is available. The kit comes with demo application and GUI software with source codes.

Description:

The R14AB performs all framing and synchronisation functions and hence a simple low cost microcontroller is sufficient to build a complete ISO 14443-compliant reader. The direct antenna driver system with automatic antenna tuning (patent pending) provides high utilisation of power and reduction of BOM, which are essential in battery-powered RFID readers with very small form factor.


Key Features:

• Supply voltage range: 2.4V to 3.6V.
• Automatic ASK modulation depth adjustment.
• Extremely efficient for applications requiring low power consumption (@3.3V):
• 25 mA for 40 mW output power.
• 16 mA for 15 mW output power.
• High-resolution RSSI (8-bit A/D converter).
• Integrated supply regulators improving PSSR.
• Integrated high-power output amplifier:
• 400 mW with antenna tuning (@3.3V).
• 800 mW without antenna tuning (@3.3V).
• Temperature range: -40ºC to 85ºC.
• Low current consumption in NFC target mode: 3.5 µA typical.
• Supports Mifare® Ultralight 4-bit ACK/NACK reply.

Applications:

• ISO 14443A/B RFID reader systems.
• NFCIP-1 systems (NFC active communication).

Package:

• 32-LD QFN (5x5 mm; RoHS)
