EM6812- Multi I/O, Flash-based MCU

Ultra low power 8bit Flash Microcontroller. Up to 2.5 MIPS, brownout detection, powercheck functions, fast wake-up from standby - Ultra-Low Power

General 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 complex 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 and achieves an astonishing 2200 MIPS/Watt at 3V and 10MHz.
