General 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 drive outputs of 10 mA 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 8 kB of Flash memory and a RC oscillator with frequencies between 32 to 800 kHz. 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.

Errata
Supply Voltage Level Detector (SVLD)

When using the SVLD in single mode (bit VLDstart set to 1), the result of the signal conversion located in register VLDresult could not be correctly performed. The reason is that the internal circuitry (bang-gap reference biasing current) needs a set up time of about 2ms before being perfectly stabilized. As the on chip measurement lasts automatically up to 3.125 clock of ck[14] (max 0.382ms), the analogue signal to be converted could not be reliable.
The busy flag using the same ch[14] can not be used as well.

The workaround is to select the SVLD in continuous mode and read a first result of the conversion after a delay of 2ms. The following readings will be also correct as the bang-gap reference biasing current will be already stabilized. In this mode, the bit VLDstart is no more necessary. The measurement duration will start once the bit SVLDen is set to 1.
