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.
