EM6812
EM6812 is Ultra Low Power 8-bit FLASH Microcontroller manufactured by EM Microelectronic.
Description
The EM6812 is designed to be battery operated for extended lifetime applications. Brownout and powercheck functions ensure reliable operation at or near undervoltage conditions, offering greater reliability in plex operation modes. Each of the 16 I/Os is freely programmable and the microcontroller has a dual quartz and trimmable RC oscillator up to 10MHz. It has an 8-bit RISC architecture specially designed for very low power consumption. With 2 clocks per instruction, EM6812 executes up to 2.5 MIPS at 5MHz and achieves an astonishing 2200 MIPS/Watt.
