TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
Single-Chip DTS Microcontroller (DTS-21)
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 device 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 device is suitable for use in digital tuning
systems in portable equipment such as headphone stereos.
