Atmel U3280M Transponder Interface for Microcontroller DATASHEET ● Contactless power supply and communication interface ● Up to 10Kbaud data rate R/O ● Power management for contactless and battery power supply ● Frequency range 100kHz to 150kHz ● 32 x 16-bit EEPROM ● Two-wire serial interface ● Shift register supported bi-phase and Manchester modulator stage ● Reset I/O line ● Field clock extractor ● Field and gap detection output for wake-up and data reception ● Field modulator with energy-saving damping stage ● Main areas ● Access control ● Telemetry ● Wireless sensors ● Examples ● Wireless passive access and active alarm control for protection of valuables ● Contactless position sensors for alignments of machines ● Contactless status verification and/or data readout from sensors 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 Atmel U3280M includes a 512-bit EEPROM with a serial interface.
