Description
The EM6580 is a low power Flash 4-bit microcontroller
coming in a small 8-pin SO package and working up to
0.4 MIPS. It comes with an integrated 4-bit ADC and 2
high current drive outputs of 10mA and it requires no
external component. It has a sleep counter reset allowing
automatic wake-up from sleep mode. It is designed for use
in battery-operated and field-powered applications
requiring an extended lifetime. A high integration level
make it an ideal choice for cost sensitive applications.
The EM6580 contains the equivalent of 8kB of Flash
memory and a RC oscillator with frequencies between 32
to 800kHz. It also has a power-on reset, watchdog timer,
10 bit up/down counter, PWM and several clock
functions.
Development tools include windows-based simulator
program debugger, assembler and real time emulator.
