RA8816N pdf
Version 1.2
RA8816N
144x65 Character/Graphic LCD Driver
1. General Description
The RA8816N is a Dot-Matrix LCD Driver that supports both character and graphic modes. It has a
built-in 256K bytes character ROM and 1170 bytes display RAM. The embedded ROM consists of
Chinese (or Japanese for –J product), English and ASCII fonts, and the embedded display RAM
supports up to 144x65 dots LCD panel. The RA8816N also provides a scrolling buffer memory for
scrolling functions. It supports vertical and horizontal scrolling features, and all of these functions are
executed by hardware.
In character mode, the RA8816N supports Traditional Chinese (BIG5), Simplified Chinese (GB) and
Japanese (S-JIS) code. The system (MPU) does not need to take a lot of time to show the Chinese or
Japanese font in this mode. It also provides small ASCII (8x8) and big ASCII (8x16) fonts for English,
Japanese, European and Latin character. The RA8816N also integrates much powerful hardware that
includes contrast adjustment, 4x5 Key-Scan and eight General Purpose I/Os.
The RA8816N is a highly integrated chip of LCD controller and driver. It reduces a lot of time for system
development, and saves much cost for hardware system that due to it provides many features for
related LCD display applications.

RA8816N arduino
Version 1.2
RA8816N
144x65 Character/Graphic LCD Driver
5-2 Register Contents
The RA8816N accepts two Command Cycle from MPU. One is Register Cycle (RS = 0) and the other
one is Memory Cycle (RS = 1). MPU has to assign the register number of RA8816N before accesses
these registers. Therefore, the first byte that MPU passes to RA8816N will be stored into Index
Register and RA8816N will assume the next byte is read from or write into the register assigned by
Index Register.
IR (Index Register)
RW RS DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 0 0 ID4 ID3 ID2 ID1 ID0
ID[4:0]: These bits are used to store the register number that MPU wants to access on next cycle.
The ID[[4:0] provide 32 register numbers (00h~1Fh). But currently RA8816N only uses 25 registers
(00h~18h). All of these registers are initialed to be “00h” after RESET.
Memory Data (RAMD)
RW RS DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0/1 1 D7 D6 D5 D4 D3 D2 D1 D0
If RS is “1”, it means MPU executes the Memory Cycle for the RA8816N. When RW is “0”, MPU will
write data to Display or ICON RAM that according to the setting of MD[1:0] (bit1-0 of REG[03h]). For
example, MPU writes Big5 / GB / ASCII code to memory in Text Mode, or write bitmap data to display
memory in Graphic mode. When RW is “1”, the MPU reads data from different paths of RA8816N. It
depends on the operation mode as following:
1.Full Size Text Mode: From up to down of left side (16 bytes), and then up to down of Right side (16
bytes), total are 32 bytes.
2.Half Size Text Mode: From up to down, total 16 bytes data.
3.Small ASCII Text Mode: From up to down, total 8 bytes data.
4.Graphics Mode: From left to right, each reading is one byte (8 Pixels).
[00h] Driver Waveform Register (DWFR)
RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0
B/C
--
NW5
NW4
NW3
NW2
NW1
NW0
B/C: Select driver waveform type.
0 Î B-Type waveform. AC drive waveform alternates in every frame.
1 Î C-Type waveform. AC drive waveform is generated and alternates (n-line reversed AC drive)
in each lines specified by NW5–NW0
NW[5:0]: These bits are used to assign the Common (Line) number that internal frame signal changes
state. The number n is set as NW + 1 for C-type function. For example, NW= 4, the AC drive
will alternate each 5 commons. This function is only supported when B/C is “1” (C-Type
wave form). About the relative information, please refer to EOR description (REG[19h] Bit 0)
and Section 6-2 for detail description.
[01h] Power Control Register (PWRR)
RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 SRST MCLR -- IO_IEN KWK IOWK DOFF_Z SLP
SRST: S/W reset.
0 Î No action.
1 Î All of the registers will be initialed again except the display memory. Once this bit is set to 1
then RA8816N has to take 50us for operation and cannot accept any new command from
MCU.
MCLR: Memory clear.
0 Î No action.
1 Î Clear the Display RAM data to “00h”. Once this bit is set to 1 then RA8816N has to spend
20ms for operation and cannot accept any new command from MCU. It is not allowed that
both MCLR and SRST are set to ”1” or MCLR will be no effect.
