The S1D13A05 is a LCD graphics controller that provides the interface between the TFT colour LCD
display and the V850ES microcontroller. The S1S13A05 provides a 2-D Hardware Acceleration
Engine to improve the drawing functions and includes a SRAM display buffer of 256Kbytes. The
S1D13A05 also incorporates a USB controller, but this is not discussed in this manual.
The 20Mhz CLKOUT signal from the V850ES is supplied to the S1D130A5.
A 48Mhz clock is available to the Epson S1D13A05 device, but is not used on the Touch
The S1D13A05 supports a “SwivelView” mode which allows the display to be rotated 0
270
Normally the top edge of the TFT colour LCD display is when the flexible connector is orientated on
the lefthand side of the display. The demonstration kit uses the Epson LCD driver in SwivelView so
that the display is rotated 90
LCDConf.h)
The S1D13A05 device drives the LCD display in 16bits per pixel (bpp) mode so approximately 65000
different colours are achievable.
The initialisation functions and parameters are handled by the emWin library functions from Segger
Microcontroller Systeme. Please refer to the software section and Segger documentation for further
details.

The NL2432HC22-41K TFT colour LCD display module is a 240(h) x 320(v), 3.5” amorphous-silicon
(a-Si) TFT active matrix LCD panel with touch panel and a back light. (The normal aspect of the
screen is in portrait mode with the flexible connector ribbon on the left side of the panel).
The LCD display utilises
display.
Although the display is capable of over 250,000 colours (6 bits per colour), approx 65000 colours are
available on this demonstration kit as the Epson S1D13A05 lcd companion IC drives the LCD panel
via a 18bit interface.
The demonstration software utilitising the Segger emWin graphics library uses 565 colour mode.
Images and graphics in the software design are handled in 16bit-mode, i.e. 5green, 6red, 5blue. The
colour index is translated to 18-bits before writing to the Epson LCD device.
Please refer to Chapter 13 “Colour Index” for further information.
