The SPMC75x family, the 16-bit architecture product, carry the newest 16-bit
microprocessor, μ 'nSP (Microcontroller and Signal Processor),
developed by Sunplus Innovation Technology. The SPMC75x integrated many function modules
inside, such as PWM generator for inverter motor, full function compare/capture,
position detection for BLDC motor, quadrature-encoder pulse circuit,
multi-functional I/Os, UART, SPI, ADC and timers and many others. With the
supported by these modules, the devices are suitable for home appliances with
inverter motors, standard industrial inverter motors and s erver control , etc.
