SMD EM4095-HM-SO16-A SOIC-16

Read/Write analog front end for 125kHz RFID Basestation
Description
The EM4095 (previously named P4095) chip is a CMOS
integrated transceiver circuit intended for use in an RFID
basestation to perform the following functions:
- antenna driving with carrier frequency
- AM modulation of the field for writable transponder
- AM demodulation of the antenna signal modulation
induced by the transponder
communicate with a microprocessor via simple interface.
Features

Integrated PLL system to achieve self adaptive
carrier frequency to antenna resonant frequency

No external quartz required

100 to 150 kHz carrier frequency range

Direct antenna driving using bridge drivers

Data transmission by OOK (100% Amplitude
Modulation) using bridge driver

Data transmission by Amplitude Modulation with
externally adjustable modulation index using single
ended driver

Multiple transponder protocol compatibility
(Ex: EM400X, EM4050, EM4150, EM4070, EM4170,
EM4069….)

Sleep mode 1µA

USB compatible power supply range

40 to +85°C temperature range

Small outline plastic package SO16
Applications

Car immobiliser

Hand held reader

Low cost reader
