DESCRIPTION
The embedded CGROM is capable to display the alphaset of international standard ISO 8859-1/2/3/4. It includes 256x4 characters and can satisfiies almost English or Eurpean language family countries. For graphic usage, RA8872 supports a 2D Block Transfer Engine(BTE) that is compatible with 2D BitBLT function for processing the mass data transfer function. The geometric speed-up engine provides user an easy way to draw the programmable geometric shape by hardware, like line, square and circle. Besides, many powerful functions are combined with RA8872, such as screen rotation function, scroll function, graphic pattern, 2-layer mixed display and font enlargement function. These functions will save user a large of software effort during developement period. RA8872 is a powerful and cheap choice for color application. To reduce the system cost, RA8872 proivde low cost 8080/6800 MCU I/F, a flexible 4-wires Touch Panel controller, PWM for adjusting panel back-light and some GPIOs. With the RA8872 design-in, user can achieve an easy-to-use, low-cost and high performace system compared with the other solution.
