General description

The EXL7567 is an intelligent graphic LCD module suitable for data visualization and man-to-machine terminal applications. The module uses a 3.8 inch 320x240 dot matrix monochrome LCD and it is equipped with an integrated resistive touch-screen panel and white-LED backlight.
The LCD is driven by an 8-bit RISC microcontroller (Atmel ATmega128) which provides a wide set of digital and analog general-purpose I/O lines for interfacing external boards.
Two on-board asynchronous serial interfaces, which can be set to operate in TTL, RS-232 or RS-485 electrical standards, are also provided and allow easy interfacing with microcontrollers or personal computers. A USB port (device only) is also available. Furthermore EXL7567 provides a built-in Real Time Clock with automatic calendar.
The microcontroller has 128 Kbyte of flash program memory for application software while general data and bitmap images can be stored in the on-board 2 Mbyte flash memory.

Application software can be developed both in C-language (using low cost or free c-compilers) and in Assembler, while software downloading can be performed by a low cost in-system programmer. Source library for LCD and on-board peripheral control are supplied in order to speed-up application development.
