The TagMicro-TX is designed for battery operated immobilizer and remote keyless entry applications. The transponder part is protocol and instruction-set compatible with the existing Sokymat stand-alone transponder and works even without a battery. Additional commands for μC communication are also implemented. A powerful UHF- transmitter circuit is built in enabling a single chip application.
The μC 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 trimmable 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-TX
executes up to 5 MIPS without compromising battery-lifetime. The battery management feature allows batteries to be recharged by a 125 kHz magnetic field.
