CRX14 Datasheet (STMicroelectronics) - I2C Short Range Contactless Coupler

CRX14, I2C Short Range Contactless Coupler

The CRX14 is a contactless coupler, compliant with the short range ISO14443B standard controlled, using the two wire I²C bus.

The CRX14 generates a 13.56MHz signal on an external antenna.

Transmitted data are modulated using Amplitude Shift Keying (ASK) modulation.

Received data are demodulated from
