Sub-1V (0.6V) 8bit Flash MCU
DC-DC Converter, E2PROM
Description
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.
