HD66765 - 396-channel Segment Driver

General Description

peThe HD66765, 396-channel segment driver LSI, displays 132RGB-by-176-dot graphics on STN Sdisplays in 4096 colors.

It is for driving STN color LCD displays to a maximum of 132RGB by 176 ydots, in combination with the HD66764 common driver.

Key Features

  • 132RGB x 176-dot graphics display LCD controller/driver for 4,096 STN colors (when HD66764 is used).
  • Low-voltage drive and flickerless PWM grayscale drive.
  • 16-/8-bit high-speed bus interface and serial peripheral interface (SPI).
  • High-speed burst-RAM write function.
  • Writing to a window-RAM address area by using a window-address function.
  • Bit-operation functions for graphics processing:  Write-data mask function in bit units  Logical operat.
