MC56F82748VLH

The MC56F82748VLH is a Digital Signal Controller offers outstanding power consumption at runtime with exceptional performance, precision and control. The digital signal controller (DSC) is based on the 32-bit 56800EX core. Each device combines, on a single chip, the processing power of a DSP and the functionality of an MCU with a flexible set of peripherals to support many target application such as circuit breaker and home appliances. Increases system safety by restricting user code from accessing key memory locations and peripherals reserved for supervisor access. It enables compact PCB design for space-constrained applications while still providing the precision and control needed. 32-bit core provides math capabilities needed for advanced power efficiency and motor control applications. Single-cycle math computations, fractional arithmetic support and parallel moves improve performance, driving tighter and faster control loops.
