RA8806

Preliminary Version 1.0

Two Layers Character/Graphic LCD Controller

1. General Description

RA8806 is a LCD controller for Dot-Matrix type STN-LCD which supports both character and graphic mode

display. The RA8806 has built-in two Display Data RAM(DDRAM) for two layers display, and has an

embedded font ROM which is capable of displaying the full-size(16x16 pixels) traditional Chinese font(BIG5,

13973 characters) or simplified Chinese font(GB, 9216 characters). RA8806 also contains 4x256 embedded

half-size (8x16 pixels) characters that can display ISO8859-1 ~ 4(or called Latin-1 ~ 4) alphabets using at

most of English speaking and Europe countries.

RA8806 supports 8080/6800 MPU protocol interface, which is capable of switching the interface with 4-bits

or 8-bits data bus. For LCD driver interface, it can be set to 4-bits or 8-bits data bus. The maximum

resolution of RA8806 is 320x240 pixels in normal mode, and 640x240 or 320x480 pixels in extension mode.

By using the font rotation mode, which can implement the “vertical” font display. The embedded intelligence

touch panel controller provides the 4-wires resistance-type Touch Panel interface. The PWM output

provides an easy contrast or back-light control method for LCD panel. RA8806 also provides a 4x8(32 keys)

or 8x8(64 keys) powerful and smart Key-Scan interface includes long-key function. The flexible interrupt and

polling mechanism can make it easy to control touch panel, key-scan and power mode functions. Also it can

greatly reduce the MPU loading. The embedded 512Byte character generation RAM (CGRAM) allows user

to build maximum 16 full-size or 32 half-size fonts. Even with the single layer display, the other unused layer

can be used as CGRAM too. In this setting, the amazing 300 full-size and 600 half-size user created fonts or

symbols are supported.

In addition, RA8806 supports 4-gray-scale display in FRC mode. The bit-arrangement is compatible for most

gray level picture and easy to program. RA8806 also includes many useful functions, like area scroll, font

inverse, font bold, font enlargement, memory clear function and so on. An innovative mechanism of “no-

flicker” mode is provided in RA8806. It’s effective for removing the “flicker” in frequently display data

Read/Write. User can easily improve the display quality by RA8806.

RA8806 is a powerful and flexible LCD controller. It provides the total solution for the middle-size mono LCD

controller. User can save large amount of time for system development and the cost of hardware system.

2. Feature

panel, key-scan and power mode

programming.
