TC9328AF - Portable Audio DTS Controller

Description

Pin No.

Output common signals to LCD panels.

Through a matrix with pins S1 to S22, a maximum 88 segments can be displayed.

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.
