1. Introduction
SSD1963 Eval Rev2A is a developmen board for Solomon SSD1963 display
con roller which provides 1,215K by e frame buffer wi h parallel MCU in erfaces
for RAM-less LCD panels up o 864x480 a 24-bi per pixel resolu ion. Wi h linear
vol age regula ors, LED backligh circui s, and FPC connec ors for ouch panels
all buil -in, users are provided wi h all necessary circui ry for es ing TFT panels
of differen size wi h heir own choice of hos microcon rollers.
A represen a ion of he board layou is shown in Figure 1.1. The board includes
hese key fea ures, as indica ed in he diagram:

1. Vol age regula ors for 5V, 3.3V, and 1.2V driving LED backligh (5V), in erface
supply power for LCD and digi al I/O (3.3V), as well as he core supply
vol age (1.2V) for SSD1963.
2. Four FPC connec ors (J1~J4) for differen LCD panels. There are dozens of
TFT pin-ou defini ions as here is no indus rial s andard for his. Only four
connec ors will no cover all of he TFT in erfaces bu a leas four panel sizes
have been verified including 3.5”, 4.3”, 5.6”, and 7” TFT panels on his
evalua ion board.
3. Two FPC connec ors (J5, J6) of bo om con ac for ouch panels. Some panels
have individual FPC for Touch Panel while o hers have Touch Panel signal
in egra ed wi h da a bus on a single FPC. These FPC connec ors of 0.5mm and
1.00mm pi ch provide a convenien access o Touch Panel signals in case he
signals are separa ed from he da a-bus-FPC. This is very common for large
panel size like 5.6” and 7” panels.
4. Two LED backligh circui s for
a. High vol age 20mA cons an curren whi e LED driver (CAT4237, On
Semiconduc or Inc). The CAT4237 is a DC/DC s ep-up conver er ha
delivers an accura e cons an curren source driving 6 o 8 whi e LEDs
in series. Ou pu of CAT4237 is rou ed o J3 and J4 for 4.3” and 3.5”
panels, respec ively.
b. 22V high curren boos whi e LED driver (CAT4139, On
Semiconduc or Inc). The CAT4139 is a DC/DC s ep-up conver er ha
delivers an accura e cons an curren ideal for driving parallel s rings
of up o five whi e LEDs in series or up o 22V. TFT panels of larger
size (>5.6”) require a lo more whi e LEDs han small panels. Le ’s ake
an example from our 7” TFT panel. The whi e LEDs are organized in 8
parallel groups of 3 LEDs in series as shown in Figure 1.2. The curren
required is 160mA (20mA x8) and he vol age requiremen is 9.9V.
The CAT4139 is capable of delivering 750mA wi h vol age as high as
22V under a single 5V DC supply. Ou pu of CAT4139 is rou ed o he
high vol age connec or J7.

5. S andard 40-pin 2.54mm box header for MCU in erfaces. This box header
provides a direc s ack wi h our PIC24/32 Eval RevC2 board via a fla cable
which is included wi h every board SSD1963 Eval Rev2A sold.

3. Software
Several demo programs are provided for quali y assurance. These programs
have been developed under Microchip Graphics Library Version v2.00 wi h a low
level driver for SSD1963 developed by us.
However, I must emphasize that, it is not restricted to use Microchip’s
microcontrollers to interface the SSD1963. Any microcon roller or processor
ha is able o genera e he required con rol signal (CS#, DC, RD#, WR#, and
D[23:0]) will be able o drive SSD1963. There are few Graphical Libraries such as:
• Luminary (now belongs o Texas Ins rumen s) Micro Graphics Library

The TFT panel (model # TY700TFT800480Rev01) is a WVGA 262k color LCD
module. LED backligh and Touch Panel are connec ed by individual connec ors.
Including he FPC for da a, here are hree connec ors o be ins alled. Turning o
he bo om side of he LCD module, we will see a 40-pin bo om con ac FPC
connec or as shown in Figure 4.1. Mos likely an 18cm flex cable has been
ins alled for you. If no , please connec i wi h he silver con ac s of he flex cable
downwards. Figure 4.2 illus ra es how he 7” TFT panel is connec ed.

Impor an message: There are hree 40-pin FPC connec ors onboard. They are J1,
J2, and J3. They come from he same manufac urer of he same model bu hey
have been designed o connec differen TFT panels. Don’ confuse hem;
o herwise, your TFT panel may be damaged.
Connec he 18cm flex cable of TY700TFT800480 o only J1! This ime, silver
con ac s of he flex cable should be facing upwards. Then, J7 connec ion can be
made for backligh . Connec or J7 is a high vol age connec or which is wired o
CAT4139 for a driving curren as high as 160mA. Figure 4.3 illus ra es he
connec ions.
Finally, connec he FPC for Touch Panel o J5 as shown in Figure 4.4. Use a
