Overview

TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9328AF Portable Audio DTS Controller (DTS-21) TC9328AF The TC9328AF is a single-chip DTS microcontroller for portable audio incorporating 230 MHz prescaller, 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.

Key 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. Features Weight: 0.45 g (typ. ).
  • CMOS DTS microcontroller LSI with built-in 230 MHz prescaller, PLL, and LCD driver.
  • Operating voltage: VDD = 0.9 to 1.8 V (typ. : 1.5 V.
