General Description The RA8802/8820 is a Character/Graphic dot-matrix liquid crystal display controller (LCD) with embedded 512K Byte Font ROM. The RA8802 supports up to 320x240 LCD panel size and RA8820 supports up to 240x160. In tradition, users need a graphic LCM to display Chinese characters. Now Chinese character’s display of RA8802/8820 presents a revolution. The RA8802/8820, instead of a MCU, can directly deal with the access of Chinese/English fonts that consist of BIG5 or GB, and ASCII code. The RA8802/8820 have some main functions as following. It’s equipped with 8-bit ADC, supporting touch panel interface. DAC is 5-bit, providing the brightness control of the LCD panel. The RA8802/8820 built in PLL/OSC two circuits provides user choice to generate system clock. The interface of RA8802/8820 fits both of 8080/6800 series’ MCU and 4/8-bit data bus. Besides that, the interface of LCD driver is compatible with many types of LCD drivers on the market. 2.

Function Description 6.1 MCU Interface The RA8802/8820’s MCU interface support Intel (8080) or Motorola (6800) 4/8 bits data bus. Users could use SYS_MI to control. Non-Pull when 6800 MCU is used. Pull low when 8080 MCU series are used. 8080 MCU RA8802 RS A0 A1-A7 IORQ Decoder CS1 CS2 SYS_MI D0-D3 (D0-D7) D0-D3(D0-D7) RD RD WR WR RES RST Figure 6-1：8080 (4/8-bit) MCU Interface Diagram 6800 MCU RA8802 RS A0 A1-A7 VMA VDD Decoder CS1 CS2 SYS_MI D0-D3 (D0-D7) D0-D3(D0-D7) EN EN R/W R/W RES RST Figure 6-2：6800 (4/8-bit) MCU Interface Diagram 6.2 Command/Decoder Register Circuit This circuit store and implement the command from MCU Interface. The Register [00h, 08h, 10h] treats the whole chip and cursor setup. The Register [20h, 30h, 40h, 50h] can setup the work range maximum RAiO TECHNOLOGY INC. 19/45 www.raio.com.tw RA8802/8820 Version 1.4 Character/Graphic LCD Controller and minimum limit. When appreciate setup with Register [10h] bit3, [F0h] bit3 and [60h, 70h] the RA8802/8820 can offer powerful variety meet various application. The Register [28h, 38h, 48h, 58h] of RA8802 can satisfy various LCD display from (0,0)~(320,240) pixels. The Register [28h, 38h, 48h, 58h] of RA8820 can satisfy various LCD display from (0,0)~(240,160) pixels. Powerful INT via Register [A0h, B0h, B8h] reduce MCU polling cycle to Interrupt interactive utility. Therefore we can use low end MCU to cost down and help the whole system reduce BOM cost. 6.3 Display Data RAM (DDRAM) Display data RAM (DDRAM) stores bit mapping pixel data and display attribute codes for displaying data. A full-size font is displayed using two bytes, and a half-size font is displayed using one byte. DDRAM displays only that data stored within the range corresponding to the DDRAM. Data stored outside the range is ignored. Refer to combined display of full-size and half-size characters for details on character codes stored in DDRAM. The display data RAM stores pixel data for LCD. For RA8802, it is a 320 column by 240 row addressable array maximum. For RA8820, it is a 240 column by 160 rows. The time required to transfer data is very short. The microprocessor writes and reads data to/from the RAM through data bus. As the LCD controller operates independently, data can be written into the RAM at the same time as the data is being displayed, without the LCD to flicker. If apply to the character/graphical mix mode. RA8802/8820 can easy store and display the data/picture which user desired.

RA8802/8820 could both support 4-bit and 8-bit LCD driver interface. SYS_LD is for LCD driver data bus selection. Non-Pull when 8-bit LCD driver is used. Pull low when 4-bit LCD driver is used. 6.5 LCD Display The RA8802 supports up to 320x240 LCD Panel, and RA8802 supports up to 240x160. Users could RAiO TECHNOLOGY INC. 20/45 www.raio.com.tw RA8802/8820 Version 1.4 Character/Graphic LCD Controller setup the Register to change the size of the Display Panel. 6.6 ROM RA8802/8820 embedded 512KByte Font ROM also provide external 512KByte Font ROM Interface can use put the standard and special fonts of BIG5, GB, and ASCII code. It can support the display 16x16 dot for full-size fonts consisting of Chinese, 8x16 dots for half-size fonts of alphanumeric characters and symbols in the same display. For example, when MCU sends Big5 code (2 Bytes), RA8802/8820 will read Font code (32 Bytes) from ROM, which is matching with Big5 code, and then deliver them to DDRAM. 6.7 PLL/OSC Circuit The internal system clock of RA8802/8820 is generated from the following way: Use an external 32768Hz X’tal and internal PLL circuit Use an external Resistor for internal RC-Oscillator The pin SYS_FQ is for RA8802/8820 clock source selection. Non-Pull will enable internal PLL circuit and X’tal will be the clock source of RA8802/8820. Pull low when RC oscillator is used and it will disable internal PLL. The Figure 6-4 is the application circuit of clock. If select RC Oscillator mode, then pin XA, XB and LPF should be floating. If X’tal and PLL mode is selected, then RA and RB should be floating.

If Rf is increased or power supply voltage is decreased, the oscillator frequency decreases. RAiO TECHNOLOGY INC. 21/45 www.raio.com.tw RA8802/8820 Version 1.4 Character/Graphic LCD Controller 6.8 DAC RA8802/8820 is built-in one 5-bit fixed current type Digital-to-Analog Converter (D/A). Because DAC will generate different current output, users can make use of it to control external boost circuit and let the voltage level which supply to LCD Panel will be changed by different setup of DAC. Then users can use program to control the brightness of LCD through MCU. 6.9 ADC The RA8802/8820 built in 8 Bit ADC and control circuits to easily interface to 4-write analog resistive touch screens. The RA8802/8820 continually monitors the screen waiting for a touch. When the screen is touched, the RA8802/8820 performs analog to digital conversion to determine the location of the touch, stores the X and Y locations in the registers, and can issues an interrupt.

REG [A0h] INTR controls the setup of Interrupts. RA8802/8820 provides a Busy signal. When BUSY Flag is “1”, which means RA8802/8820 is in busy status, so RA8802/8820 couldn’t access data of DDRAM but still accept the commands from registers. This BUSY pin should be connected to MCU I/O input, and then MCU have to poll this pin before accessing RA8802/8820. 6.11 Power Saving Mode The RA8802/8820 has four operation mode Æ Normal Mode, Standby Mode, Sleep Mode and Off Mode. Please refer to the register [00h] LCR of Chapter 5.2. 6.12 ASCII Block Selection The RA8802/8820 built-in four blocks of ASCII Font. It is including many special symbols that for users display. This feature is set by Bit[1:0] of Register [F0h]. If user want to create their special symbol or picture then it’s possible to make new ROM Code.

But the moving unit for common is pixel. For example, if user want to show “制” at third location of upper-left, then the Register value are CPXR = 04h, CPYR = 00h. If user want to show “器” at first position of second line, the register value are CPXR = 00h，CPYR = 10h. Please refer to Figure 7-9. The cursor position is controlled by Register CPXR and CPYR for both text and graphics mode. You can also setup the Auto-Increase mode for write to DDRAM or read data DDRAM. The boundary depends on active window. 00 01 02 03 00 : : : 10h : : : 20h : : : : : : : : : : : : EFh 04 05 ....……….............……………………......... 39 320(Segment) x 240(Common) Figure 7-9 : Example of RA8802 Cursor Position 7.7.2 Cursor Display and Blinking The user could control cursor On/Off or Blinking. The register [80h] BTR is used to set up the blinking time. Blinking Time = BTR[80h] Bit[7..0] x (1/Frame_Rate) RAiO TECHNOLOGY INC. 29/45 www.raio.com.tw RA8802/8820 Version 1.4 Character/Graphic LCD Controller 7.7.3 Cursor Width and Height The cursor height is controlled by register CSCR Bit[7..4] from 1~16pixel. It does depend on user’s requirement. 1 Pixel 2 Pixel 3 Pixel 16 Pixel Figure 7-10 : Cursor Height In text mode, RA8802/8820 provide two widths for selection. If Register CCR bit0 -- CSD = 0, the cursor width fixed to one byte(8 pixel). If CSD =1, the cursor width is depend on the character. If user sends a full size Chinese character, then the cursor width will become 2byte width(16 pixel). If user shows a half size character then the cursor width will change to one byte(8 pixel). 7.8 Display Window and Active Window The RA8802/8820 provides two windows for real application -- Display Window and Active Window. The Display Window is the actual size of LCD panel. Active is a sub-window in Display Window. The boundary of cursor shift depends on the active window. For RA8802, if LCD panel is 320x240 pixel then the display window size is 320x240. We can create an active window in the display window like Figure 7-11. This figure show the display size is 320x240, and a 160x160 active window is on the upper-middle.
