The 56F8027 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 56F8027 is well-suited for many applications. The 56F8027 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. The 56F8027 supports program execution from internal memories. Two data operands can be accessed from the on-chip data RAM per instruction cycle. The 56F8027 also offers up to 53 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration. The 56F8037 Digital Signal Controller includes 64KB of Program Flash and 8KB of Unified Data/Program RAM. The 56F8027 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, QSCIs, QSPIs, I2C, PITs, 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).
