These near field communication, high frequency (NFC/HF), radio identification (RFID) reader integrated circuits (ICs) deliver high-end performance in a compact package for reader plus tag solutions in consumer, medical and industrial battery-powered applications.
The STMicroelectronics ST25R100 and ST25R200, come in a small 4mm x 4mm 24-pin TQFN package offering high dynamic power output (0.8V/1.2W) for easy integration into applications with long-read range, small antennas and improved low-power card detection. The ST25R100 reader IC provides an entry-level option for cost-sensitive applications with a radio-controlled (RC) oscillator and a programmable timer to automatically scan for cards or other NFC-enabled devices while in wake-up (WU) mode.
This IC is ideal for accessory recognition, automatic parameter setting, identification or access control with data transfer speeds of up to 6Mbit/s at 0.8V output power, external communication interfaces including a serial peripheral interface (SPI), and a wide 2.7V to 5.5V power supply range with an equally wide -25°C to 85°C ambient temperature range.
The ST25R200 reader IC adds extended features for medium to high-power applications like industrial IoT and gaming with integrated electromagnetic device (EMD) handling, active wave shaping (AWS) with overshoot or undershoot protection, and an RC oscillator with a programmable timer to scan for cards or other NFC-enabled devices while in WU mode.
The ST25R200 also offers a serial peripheral interface (SPI) with data transfer speeds of up to 10Mbit/s with a 1.2W output power, a wide 2.7V to 5.5V power supply range with a broad -40°C to 85°C ambient temperature range.
The STMicroelectronics RFID readers are available from Mouser Electronics in the EMEA, Americas and Asia/Pacific regions.
