The Microchip dsPIC33CH256MP505 digital signal controllers (DSCs) feature dual 90 & 100 MIPS 16-bit dsPIC® DSC cores with integrated DSP and enhanced on-chip peripherals. It operates on 3V to 3.6V voltage range. It has 256Kbyte Program Memory, 48KB DSC enable the design of high-performance, precision motor control systems that are more energy efficient, quieter in operation and provide extended motor life. It can be used to control BLDC, PMSM, ACIM, SR and stepper motors. This DSC enable the design of switched mode power supplies such as AC/DC, DC/DC, UPS and PFC, providing high-precision digital control of Buck, Boost, Fly-Back, Half-Bridge, Full-Bridge, LLC and other power circuits to reach the highest possible energy efficiency.
