TC9349AFG

TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC9349AFG

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.

Weight: 0.32 g (typ.)
