2 NuDesign HMI-N9H20 Board Introduction The following figures show the NuDesign HMI-N9H20 development board, in which the front and back integrated 32-bit microcontroller embeds an outstanding CPU core ARM926EJ-S, runs up to 192MHz, with 16KB I-cache, 16 KB D-cache and MMU, 32KB embedded SRAM and 12KB IBR(Internal Boot ROM) for booting from USB and SPI FLASH; Audio controller NAU8822A is a low power, high quality CODEC for portable and general purpose audio applications, it includes drivers for speaker, headphone, and differential or stereo line outputs, and integrates preamps for stereo differential microphones, significantly reducing external component requirements. The board also supports several extended connections. Users can use it to develop and verify applications to emulate the real behavior.
