EM4095 125kHz RFID Reader Front-End IC

Name: EM4095 125kHz RFID Reader Front-End IC
Brand: EM Microelectronics
SKU: EM4095

The EM4095 is an EM Microelectronics 125kHz RFID reader/base-station analog front-end that directly drives the antenna and handles AM modulation/demodulation. An integrated PLL self-adapts to antenna resonance (no external quartz), connecting to an MCU via a simple interface (MOD / DEMOD_OUT / RDY_CLK), with a 4.1~5.5V supply in an SO16 package — common in access control, animal ID, and immobilizer applications.
