MC56F8x 16-bit Digital Signal Controllers NXP Semiconductors MC56F8x 16-bit Digital Signal Controllers (DSC) combine the processing power of a Digital Signal Processor (DSP) and the functionality of a Microcontroller (MCU) with fast and powerful peripherals. The MC56F8x DSCs are based on the 16-bit 56800E DSC core, with performance up to 60MIPS. These devices are ideal for digital power conversion applications, such as board-mounted digital power supplies for servers, industrial and telecom power supplies, and advanced motor control.
