CRX14RF/IF射頻/中頻RFID的RFID射頻接入監(jiān)控IC規(guī)格書PDF中文資料

CRX14屬于RF/IF射頻/中頻RFID的RFID射頻接入監(jiān)控IC。由意法半導體集團制造生產(chǎn)的CRX14RFID，射頻接入，監(jiān)控 ICRFID 或射頻接入監(jiān)控 IC 是配置為射頻識別 (RFID) 讀取器、應答器、無源接入/無源啟動處理器和輪胎壓力監(jiān)測系統(tǒng) (TPMS) 的半導體器件。這些器件的設計符合 EPC、ISO、NFC、MiFARE 和 FeliCa 等特定 RFID 標準，并通過 I2C、SPI、UART、USB、PWM、RS232、RS422、RS485 及其他接口進行通信。

SUMMARY DESCRIPTION

The CRX14 is a contactless coupler that is compliant with the short range ISO14443 type-B standard. It is 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). Received data are demodulated from the PICC (Proximity in tegrated Coupling Card) load variation signal, in duced on the antenna, using Bit Phase Shift Keying (BPSK) of a 847kHz sub-carrier. The Transmitted ASK wave is 10 modulated. The Data transfer rate between the CRX14 and the PICC is 106 Kbit/s in both transmission and reception modes.

The CRX14 follows the ISO14443 type-B recommendation for Radio frequency power and signal interface.
