TC9329FA/FB

TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC9329FA, TC9329FB

Portable Audio DTS Controller (DTS-21)

The TC9329FA/FB is a single-chip DTS microcontroller for

portable audio incorporating 230 MHz prescaler, PLL, and LCD

driver. In addition to a 20 bit IF counter, 6 bit A/D converter,

serial interface, and buzzer function, the device supports an

interrupt function, 8 bit timer/counter, and 8 bit pulse counter.

The LCD driver features built-in 1/4 duty, 1/2 bias and a 3 V

voltage doubler boosting circuit, implementing stable LCD. The

power supply voltage ranges from 0.9 to 1.8 V. Because of its

low-current consumption (CPU: 80 µA (max)), the device is

suitable for use in digital tuning systems in portable equipment

such as headphone stereos.
