TAGMICRO-TxFN
Ultra Low Power 8-bit Microcontroller and Fractional-N RF Transmitter
The Smartrac TAGMICRO-TxFN is designed for immobilizer and battery operated remote keyless entry (RKE) applications. The transponder part is protocol and instruction-set compatible with the existing Smartrac products and works even without a battery. Additional commands for microcontroller communication are also implemented. A powerful fractional-N based UHF-transmitter circuit is built in enabling a single chip application.
The microcontroller offers brownout, power-check & glitch detection functions to ensure reliable operation at under voltage conditions. Each of the 16 I/Os are freely programmable. A trimmed RC oscillator of up to 10MHz frequency allows stable operation without need for external resonator. Featuring an 8-bit RISC architecture specially designed for very low power consumption, TAGMICRO-TxFN executes up to 5 MIPS without compromising battery-lifetime. The battery management feature allows batteries to be recharged by a 125 kHz magnetic field.
