Products - GPF32001A*

General Description

The Generalplus GPF32001A is highly integrated system-on-a chip and targets a cost-effective, high performance micro-controller solution for electronic dictionary, education and learning applications. It embeds a μ'nSP^® 2.0 (16-bit CPU developed by Sunplus) with 4KB I-cache, 32 channels sound process unit (SPU), SDRAM controller, ROM/SRAM/NOR FLASH/NAND FLASH with ECC Memory controller, UART/IrDA interface, four channel DMA controller, six-channel 16-bit timers, SD/MMC memory interface, USB mini-host/device, mono STN-LCD and TFT-LCD interface, interrupt controller, SPI master/slave controller, Key scan controller, programmable I/O ports, 16-bit DAC for audio playback, 12-bit ADC, PLL, and embedded 28K*16-bit SRAM.
By providing a complete set of common system peripherals, the Generalplus GPF32001A chip minimizes overall system costs and eliminates the need to configure additional components. The GPF32001A 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.
