The Microchip dsPIC33EP128GS808 family is a high-performance dsPIC® digital signal controller (DSC) with up to 128 KB of dual-partition Flash memory with live update capability, advanced analog features, and enhanced core independent peripherals (CIPs). It is suitable for high-end digital power applications such as AC/DC power supplies, DC/DC converters, power inverters, and advanced lighting applications. In addition to increasing the amount of Flash memory available within the family, select variants are offered in an 80-pin package giving designers more interface pins to fulfill the requirements of more sophisticated designs.
