Description

The TC9349AFG is a single-chip DTS microcontroller for portable audio incorporating a 30 MHz prescaler, PLL, and LCD driver. In addition to an IF counter, serial interface and buzzer function, the device incorporates an interrupt function, timer counter, pulse counter, electronic volume function and A/D converter

The TC9349AFG also supports selection of 1/4-duty 1/2 bias or 1/4-duty 1/3 bias for the LCD driver, while a built-in 3 V voltage doubler boosting circuit implements stable operation of the LCD monitor.

The power supply voltage ranges from 0.9 V to 1.8 V. Due to its low-current consumption, the TC9349AFG is suitable for use in digital tuning systems in portable equipment such as headphone stereos.
