EM4097数据手册RF/IF射频/中频RFID的RFID射频接入监控IC规格书PDF

描述 Description

The EM4097 (previously named P4097) chip is a CMOS integrated transceiver circuit intended for use in an RFID basestation to perform the following functions:
·Antenna driving with carrier frequency to transfer energy to the transponder
·Data transfer to writable transponder by amplitude modulation (ASK) of the field (100% modulation ratio, called OOK, “on”-“off” keying)
·Data transfer from transponder by amplitude- or phase demodulation (ASK or PSK)
·μC Interface to communicate with a microprocessor
Solutions
·Animal ID reader
·Hand held Low Frequency reader

特性 Features

·Integrated PLL system to achieve self adaptive carrier frequency to antenna resonant frequency
·Chip can be forced to run with external clock, division ratio 32
·100kHz to 150kHz carrier frequency range
·Direct antenna driving using bridge driver
·Data transmission by OOK (100% Amplitude Modulation) using bridge driver
·Multiple transponder protocol compatibility, (Ex.: EM4102, EM4200, EM4450 and EM4205/EM4305)
·Two sampling points for demodulation, allowing extended system tolerances
·Serial μ interface for diagnosis and status control
·Very low sleep mode current consumption of 1μA typically
·USB compatible power supply range
·-40 to +85°C automotive temperature range
·Small outline plastic package SO16

简介

EM4097属于RF/IF射频/中频RFID的RFID射频接入监控IC。由制造生产的EM4097RFID，射频接入，监控 ICRFID 或射频接入监控 IC 是配置为射频识别 (RFID) 读取器、应答器、无源接入/无源启动处理器和轮胎压力监测系统 (TPMS) 的半导体器件。这些器件的设计符合 EPC、ISO、NFC、MiFARE 和 FeliCa 等特定 RFID 标准，并通过 I2C、SPI、UART、USB、PWM、RS232、RS422、RS485 及其他接口进行通信。
