U3280M中文资料Transponder Interface for Microcontroller数据手册Microchip规格书

描述 Description

The U3280M is a transponder interface for use in contactless ID systems, remote control systems, tag and sensor applications. It supplies the microcontroller with power from an RF field via an LC-resonant circuit and it enables contactless bi-directional data communication via this RF field. It includes power management that handles switching between the magnetic field and a battery power supply. To store permanent data like an identifier code and configuration data, the U3280M includes a 512-bit EEPROM with a serial interface.
