EM4094RF/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

EM4094屬于RF/IF射頻/中頻RFID的RFID射頻接入監(jiān)控IC。由EM Microelectronic - MARIN SA制造生產(chǎn)的EM4094RFID，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(yīng)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(dǎo)體器件。這些器件的設(shè)計符合 EPC、ISO、NFC、MiFARE 和 FeliCa 等特定 RFID 標(biāo)準(zhǔn)，并通過 I2C、SPI、UART、USB、PWM、RS232、RS422、RS485 及其他接口進(jìn)行通信。

General Description

The EM4094 is an integrated analog system for 13.56MHz RFID reader system. It is highly versatile so it can be used in different reader systems having sub-carrier frequencies from 212KHz to 848KHz, hence covering ISO 14443 and ISO 15693 standards.

The adaptability is achieved using a 3 wires serial interface to program the system option bits.

The transmitter generates 200 mW output power into 50? load and is capable of OOK or ASK modulation.
