

The main system has basic circuit blocks such as the Main IC (STMP3770), Flash Memory and the USB Block and

includes function blocks such as the FM-Tuner, Display and MIC. The display is connected to a 1 inch OLED.



The Serial Interface between ICs is delivered with various protocols throughout the whole system. The main IC

(STMP3770) uses I2C to operate the FM tuner by communicating with the FM tuner.



As for the display, the display utilizes the boosted 13V through the DCDC IC using Vbat, and the OLED drive IC (built

in the OLED) is operated by receiving the data from the processor.



As for the key input, keys are distinguished by differing ADC voltages for each input key (ADC is built into the main

IC.).



The built-in battery is used as a source of power, and can be charged through a USB port.
