描述 Description

GPF16, a single-chip integrating multi-processors, equips μ'nSP® (16-bit CPU developed by Sunplus Technology) and 16-channel Sound Processor Unit (SPU) for electronic pianos, portable Karaoke or other similar products. With the 16-bit CPU running up to 27MHz, most of the voice compression algorithms can be utilized with MIDI synthesizer applications simultaneously. In addition, it supports the interface with single color LCD panel up to 1024 x 256 dots and standard MIDI interface. Furthermore, it has up to 43 programmable I/Os and 128K-word ROM for electronic instrument applications. Its low power consumption offers the potentials to be used in battery-powered products.The GPF16 provides not only the high-speed performance and high quality of 16 channels synthesizer, 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.
