It combines, on a single chip, the processing power of a DSP and the functionality of a microcontroller with a flexible set of peripherals to create a cost-effective solution. Because of its low cost, configuration flexibility, and compact program code, the 56F8006/56F8002 is well-suited for many applications. It includes many peripherals that are especially useful for cost-sensitive applications, including: • Industrial control • Home appliances • Smart sensors • Fire and security systems • Switched-mode power supply and power management • Power metering • Motor control (ACIM, BLDC, PMSM, SR, and stepper) • Handheld power tools • Arc detection • Medical device/equipment • Instrumentation • Lighting ballast The 56800E core is based on a dual Harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. The MCU-style programming model and optimized instruction set allow straightforward generation of efficient, compact DSP and control code. The instruction set is also highly efficient for C compilers to enable rapid development of optimized control applications. The 56F8006/56F8002 supports program execution from internal memories. Two data operands can be accessed from the on-chip data RAM per instruction cycle. The 56F8006/56F8002 also offers up to 40 general-purpose input/output (GPIO) lines, depending on peripheral configuration. The 56F8006/56F8002 digital signal controller includes up to 16 KB of program flash and 2 KB of unified data/program RAM. Program flash memory can be independently bulk erased or erased in small pages of 512 bytes (256 words).
