描述 Description

The SNC32KP is a 4bit tiny controller series with embedded 5 channel hardware Voice/MIDIWave Processing Unit (WPU).By programming through the tiny controller in SNC32KPxxx,user’s varied applications including voice section combination; key trigger arrangement,output control, and other logic functions can be easily implementedKey peripherals include a single high quality 13bit DAC with push-pull amplifier,12 set hardware PWMIOs, constant current I/O, and the I2C is a serial communicationinterface for data exchanging.The SNC32K 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.
