RA8806
Preliminary Version 1.0
Evalution Kit User Guide
1. Overview
RA8806 is a two layers Character/Graphic STN LCD controller which supports 320x240 or up to
640x240 pixels 4 gray scale display. This chip has embedded 512KB font ROM (includes English,
European, Chinese and Japanese characters) and a intergrated touch screen controller; more powerful
features such as smart key scan, font rotation and contrast control are all included in this single chip.
RAiO provides the RA8806 evaluation kit to assist customers easy to evaluate the controller and
intergrate the LCD display with embedded system development. The kit offers an easy and lower cost
path for user to create graphic user interface on the LCD display in a short time.
RA8806 supports any STN LCD panel up to QVGA size. A RA8806 LCD controller chip and an 8051
MCU are already mounted on the board. User can display data or images on their own LCD panel by
downloading graphics from personal computer to the onboard 8051 MCU and commented source code
for the RA8806. Another onboard MCU interface is also available for user to connect to selected MCU
for their system applciations.

Figure 1-2 shows the block disgram of RA8806 Evaluation board, the details of each block will be
introduced in Chapter 3. Figure 1-3 indicates Evaluation Circumstance. For software programming and
developing the RA232 cable and download cable will be needed. If there is not a RS232 interface at
user PC, antoher USB/RS232 adapter will be required for connecting PC with the evaluation board.
User can use any standard STN LCD module (not build-in LCD controller) from STN LCD suppliers and
connect the RA8806 evaluation board with LCD module through the onboard LCD interface, or user can
purchase the RA8806 evaluation kit B for a whole demo kit that’s included a 3.8” LCD panel.

There are two types of RA8806 evaluation boards: the RA8806_TQ (use RA8806T1N in TQFP
package) and the RA8806_LQ (use RA8806L2N in LQFP package). The PCB layout and
components Library are included in the CD attached with the kit. Enables user to easily intergrate
with new design system and main board development.
The circuit drawing of RA8806_TQ evaluation board is shown as figure below.The details of each
part of schematic will be introduced in next chapters. User can use other software such as “Protel”
to open the schematic files in the attached CD to view and edit.

U3 ： MX10E8050IQC (PLCC-44), Standard 80C51 MCU core, our recommend frequency is
18.432MHz.
There is a 8051 base MCU set in the PLCC-44Pin IC socket that already intergrated in RA8806
evaluation board, part number is MX10E80511 or W78E516B40PL. User can program and edit on
this MCU by PC, and download the program into Flash Memory through USB-RA232 adapter or
RS232 interface after tool transmitted . A test Demo Program is already store in the Flash of
onboard MCU with the evaluation board. The demo program is wrote in C language that user can
test and review in the CD attached with the kit.
For details information of MX10E80511 or W78E516B40PL MCU please refer to official websites of
MXiC/Winbond (www.mxic.com.tw / www.winbond.com.tw ). There are many compatible MCU that
user can select for own applications, however the onboard IC socket is not universal
The software of Keil C is not included in the RA8806 Evaluation Kit, user can purchase software
such as “Keil C51” or visit website at www.keil.com/demo/ for details.

Most of the STN LCD panel are required booster to drive the LCD, some LCD modules have
intergrated the booster but but some are not, also the requirement to booster differs from +VLCD
or –VLCD for LCD drivers. RA8806 evaluation board contains booster for both +VLCD and –VLCD
to work with various LCD modules.

The table 3-7-1 shows original settings of the evaluation board. Due to the RA8806 evaluation boad
uses 8051 MCU I/O Port to send command and control data read/write to RA8806, therefore the
CPU data bus is 8 bit or 4 bit, and CPU Mode is 8080 or 6800. Except the interface selection of S1,
users need to operate in coordination to software settings. Refer to the “userdef.h” file of RA8806
