The Generalplus GPL162003A1 is highly integrated system-on-a chip and targets a cost-effective, high performance micro-controller solution for general-purpose applications. It embedded µ’nSP® 2.0 (16-bit CPU developed by Sunplus Technology), 7-band EQ, 3D surround, UART/IrDA interface, four channel DMA controller, ROM/SRAM/NOR FLASH/NAND FLASH with ECC Memory controller, six-channel 16-bit timers, SD/MMC memory interface, USB mini-host/device, gray/color STN-LCD interface, interrupt controller, SPI master/slave controller, I2C master/slave controller, Key scan, Generalplus IO, programmable I/O ports, 16-bits DAC/ADC for audio playback/recode, stereo headphone amplifier, 10 bits ADC for touch panel, PLL, and embedded 30K*16 bits SRAM and 128K*16 ROM.

By providing a complete set of common system peripherals, the Generalplus GPL162003A1 chip minimizes overall system costs and eliminates the need to configure additional components. The GPL162003A1 provides not only the high-speed performance and low cost for a system, but it also integrates several powerful tools into the development system, such as development system with C language, assembly compiler, linker, source debugger functions and project management tools.
