MSC1205 - 32-Bit Duplex Controller/Driver

General Description

The MSC1205 is a Bi-CMOS display driver for a 1/2-duty vacuum fluorescent display tube.

It consists of a 64-bit shift register, latch circuits, a digital diming circuit, and drivers.

The MSC1205 provides an interface with a microcomputer only by three signal lines: LOAD, DATA, and CLOCK.

Key Features

  • Power Supply Voltage: 8 to 18V (built-in 5V regulator for logic).
  • Built-in 1-terminal RC oscillation circuit (with external capacitor).
  • Built-in digital dimming circuit 10-bit resolution Programmable in the duty range of 0/2048 (0%) to 1015.5/2048 (49.6%).
  • Can directly drive 32.
  • 2 display anodes.
  • Built-in power-on reset circuit.
  • Package options: 42-pin plastic DIP (DIP42-P-600-2.54) (Product name: MSC1205-RS) 44-pin plastic QFP (QFP44.
