The 56F8025 is a member of the 56800E core-based family of Digital Signal Controllers (DSCs). 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 an extremely cost-effective solution. Because of its low cost, configuration flexibility, and compact program code, the 56F8025 is well-suited for many applications. The 56F8025 includes many peripherals that are especially useful for industrial control, motion control, home appliances, general-purpose inverters, smart sensors, fire and security systems, switched-mode power supply, power management, and medical monitoring applications. 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.

56F8025 Description
The 56F8025 supports program execution from internal memories. Two data operands can be accessed from the on-chip data RAM per instruction cycle. The 56F8025 also offers up to 35 General-Purpose Input/Output (GPIO) lines, depending on peripheral configuration. The 56F8025 Digital Signal Controller includes 32KB of Program Flash and 4KB of Unified Data/Program RAM. Program Flash memory can be independently bulk erased or erased in pages. Program Flash page erase size is 512 Bytes (256 Words). A full set of programmable peripherals — PWM, ADCs, QSCI, QSPI, I2C, PIT, Quad Timers, DACs, and analog comparators — supports various applications. Each peripheral can be independently shut down to save power. Any pin in these peripherals can also be used as General Purpose Input/Outputs (GPIOs).
