The EM6819 is designed to be battery operated for extended lifetime applications. Its large voltage range from 3.6V down to 0.9V makes it a perfect match for today‟s demanding applications. Brownout and powercheck functions ensure reliable operation at or near undervoltage conditions, offering greater reliability in complex operation modes. Each of the 24 I/Os are freely programmable and the microcontroller has a dual quartz and trimmable RC oscillator up to 15MHz. It has an 8-bit RISC architecture specially designed for very low power consumption. With 2 clocks per instruction, the EM6819 executes up to 7.5 MIPS at 15MHz and achieves astonishing 4000 MIPS/Watt.
