I. General Description
The EM785830AA is an 8-bit RISC type microprocessor with low power, high speed CMOS technology. There
are 16Kx13 bits ROM within it.
This integrated single chip has an on_chip watchdog timer (WDT, data RAM, programmable real time
clock/counter, internal interrupt, power down mode, 4-channel 10-bit A/D converter, two channel PWM output, SPI and
tri-state I/O.
