TC9329FB

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.
