Note:
*1. This rating applies to all parts of the module and should not be exceeded.
*2. The operating temperature only guarantees operation of the circuit. The contrast, response speed,
and the other specification related to electro-optical display quality is determined at the room temperature, T OP =25 ℃
*3. Ambient temperature when the backlight is lit (reference value)
*4. Any Stresses exceeding the Absolute Maximum Ratings may cause substantial damage to the device. Functional
operation of this device at other conditions beyond those listed in the specification is not implied and prolonged
exposure to extreme conditions may affect device reliability.

Control and Draw Engine
- TML files, Picture files, ICON files are stored inside FLASH memory area.
They are preloaded to HMT056ATA-C for stand alone interface use.
- Those files are preloaded via USB interface as an USB drive.
- All the interface flow and the touch response are based on the preloaded TML files
- VP variables memory is inside RAM area,
it provides real time access via UART by the HOST or display onto the TFT by TML file.
- Custom Memories are inside FLASH memory area
It can be accessed via UART interface by the HOST.
- Control and Draw Engine executes HOST commands and response respectively
- It also reports the real time Touch Key number to the HOST

5 Touch panel Design Precautions
1. It should prevent front case
touching the touch panel
Active Area (A.A.) to prevent
abnormal touch.
It should left gab (e.g.
0.2~0.3mm) in between.
2. Outer case design should take care about the area outside the A.A.
Those areas contain circuit wires which is having different thickness. Touching those areas could de-
form the ITO film. As a result case the ITO cold be damaged and shorten its lifetime.
It is suggested to protect those areas with gasket (between the front case and the touch panel).
The suggested figures are B≥0.50mm; C≥0.50mm 。
3. The front case side wall should keep space
(e.g. 0.2 ~ 0.3mm) from the touch panel.
4. In general design,
touch panel V.A. should be bigger than the LCD V.A.
and touch panel A.A. should be bigger than the LCD A.A.
