MSM6606 - 80-DOT LCD DRIVER WITH KEY MATRIX

General Description

The MSM6606 is an LCD driver for a 1/2 duty dynamic display.

It can directly drive an LCD of up to 80 segments, and one LED.

Keyboard input is now available by the internal 5 x 6 keyscan circuit, and the number of wires between the front panel and the CPU can be minimized.

Key Features

  • Power supply voltage : 5V ± 10% Temperature range :.
  • 40 to +85°C Can display an LCD of up to 80 segments (1/2 duty dynamic drive) Can directly drive one LED (IO =.
  • 15 mA max. ) Internal 5 x 6 keyscan circuit allows reading of the status of up to 30 key switches A serial interface with the CPU is implemented by LOAD, DATA I/O, and CLOCK Built-in RC oscillation circuit for LCD alternating curre.
