General description
The EM6680 is an advanced single chip CMOS microcontroller coming in packages as small as 8-pin TSSOP. It contains ROM, RAM, internal RC oscillator with metal option selectable frequency between 32kHz and 800kHz, power on reset (POR), watchdog timer, 10 bit up/down counter / timer, prescaler, supply voltage level detector (SVLD), serial interface, compare input, frequency output, and several clock functions. The low voltage and low power consumption make it a highly suitable controller for battery, stand alone and mobile equipment.
