LC75886PW: LCD Driver, 1/4 Duty, 1/3 Duty, with Key Input

The LC75886PW is 1/4 duty and 1/3 duty LCD display driver that can directly drive up to 224 segments and can control up to 5 general-purpose output ports. This product also incorporates a key scan circuit that accepts input from up to 30 keys to reduce printed circuit board wiring.

Features
  • Key input function for up to 30 keys (A key scan is performed only when a key is pressed.)
  • 1/4 duty 1/3 bias and 1/3 duty 1/3 bias drive schemes can be controlled from serial data.
  • Capable of driving up to 224 segments using 1/4 duty and up to 171 segments using 1/3 duty.
  • Switching between key scan output and segment output can be controlled from serial data.
  • The key scan operation enabled/disabled state can be controlled from serial data.
  • Switching between segment output port and general-purpose output port can be controlled from serial data.
  • Switching between general-purpose output port, clock output port, and segment output port can be controlled fromserial data. (Up to 5 general-purpose output ports and up to one clock output port)
  • Serial data I/O supports CCB format communication with the system controller. (Support 3.3V and 5V operation)
  • Sleep mode and all segments off functions that are controlled from serial data.
  • The frame frequency of the common and segment output waveforms can be controlled from serial data.
  • Switching between RC oscillator operating mode and external clock operationg mode can be controlled from serial data.
  • Direct display of display data without the use of a decoder provides high generality.
  • Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays.
  • RES pin provided for forcibly initializing the IC internal circuits.
