General Description

GPF16002A, a highly integrated System-on-a-Chip (SoC), is a cost-effective and high performance micro-controller solution for game, education and interactive learning applications.  The GPF16002A comes with an m’nSP® 2.0 CPU with 8KB I-cache and 16-channel Sound Process Unit (SPU) for electronic musical instruments, portable Karaoke or other similar products. With the 16-bit CPU running up to 96MHz, most of the voice compression algorithms can be utilized with MIDI synthesizer applications simultaneously. In addition, it supports SPI Flash controller, two-channel DMA controller, USB device, mono STN-LCD interface, interrupt controller, and many other advanced features.  Providing a complete set of common system peripherals, GPF16002A minimizes overall system costs and eliminates many additional components that other microcontrollers may require.  The GPF16002A development system integrates several powerful tools, such as system with C language, assembly compiler, linker, source debugger, and project management tool.
