SNC85F500A数据手册Sonix中文资料规格书

描述 Description

The SNC85F E/A/D 24MHz 16-bit RISC controller series is embedded Flash controllerwith multi-channel 2/8~24 hardware Voice/MIDI Wave Processing Unit (WPU). In additionto having multi-channel hardware channels, two software high quality voice channelswith SONiX HQDPCM/Audio32 algorithm is provided. Key peripherals include a single high quality 13bit DPWM audio output, Max.31-channelcomparator for cap sensing touch, three external interrupts, Max. 31ch PWMIOs, serialperipheral interface (SPI0&SPI1),IIC TX/RX, UART TX/RX, and three 12-bit timers. Thedevice features provide idle mode for real-time clock (RTC) applications and sleepmode for power savings.The SNC85F contains a Low Voltage Detector (LVD) for power management usage.The status of internal or external power can be detected and reported to the managementsoftware. There is a Low Voltage Reset (LVR) function provided to keep the whole systemfrom losing data when voltage drops to a low level.
