EM4095HMSO16A Datasheet PDF - EM Microelectronic

●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
