1.2 56F801 Description
The 56F801 is a member of the 56800 core-based family of processors. 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 56F801 is well-suited for many applications. The 56F801 includes many peripherals that are especially useful for applications such as motion control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and control, automotive control, engine management, noise suppression, remote utility metering, and industrial control for power, lighting, and automation. The 56800 core is based on a Harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. The microprocessor-style programming model and optimized instruction set allow straightforward generation of efficient, compact code for both DSP and MCU applications. The instruction set is also highly efficient for C compilers to enable rapid development of optimized control applications. The 56F801 supports program execution from either internal or external memories. Two data operands can be accessed from the on-chip Data RAM per instruction cycle. The 56F801 also provides one external dedicated interrupt lines and up to 11 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration. The 56F801 controller includes 8K words (16-bit) of Program Flash and 2K words of Data Flash (each programmable through the JTAG port) with 1K words of both Program and Data RAM. A total of 2K words of Boot Flash is incorporated for easy customer-inclusion of field-programmable software routines that can be used to program the main Program and Data Flash memory areas. Both Program and Data Flash memories can be independently bulk erased or erased in page sizes of 256 words. The Boot Flash memory can also be either bulk or page erased.

A key application-specific feature of the 56F801 is the inclusion of a Pulse Width Modulator (PWM) module. This modules incorporates six complementary, individually programmable PWM signal outputs to enhance motor control functionality. Complementary operation permits programmable dead-time insertion, and separate top and bottom output polarity control. The up-counter value is programmable to support a continuously variable PWM frequency. Both edge- and center-aligned synchronous pulse width control (0% to 100% modulation) are supported. The device is capable of controlling most motor types: ACIM (AC Induction Motors), both BDC and BLDC (Brush and Brushless DC motors), SRM and VRM (Switched and Variable Reluctance Motors), and stepper motors. The PWMs incorporate fault protection and cycle-by-cycle current limiting with sufficient output drive capability to directly drive standard opto-isolators. A “smoke-inhibit”, write-once protection feature for key parameters is also included. The PWM is double-buffered and includes interrupt control to permit integral reload rates to be programmable from 1 to 16. The PWM modules provide a reference output to synchronize the Analog-to-Digital Converters. The 56F801 incorporates an 8 input, 12-bit Analog-to-Digital Converter (ADC). A full set of standard programmable peripherals is provided that include a Serial Communications Interface (SCI), a Serial Peripheral Interface (SPI), and two Quad Timers. Any of these interfaces can be used as General-Purpose Input/Outputs (GPIO) if that function is not required. An on-chip relaxation oscillator provides flexibility in the choice of either on-chip or externally supplied frequency reference for chip timing operations. Application code is used to select which source is to be used.
1.3 State of the Art Development Environment
• • Processor ExpertTM (PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use component-based software application creation with an expert knowledge system. The Code Warrior Integrated Development Environment is a sophisticated tool for code navigation, compiling, and debugging. A complete set of evaluation modules (EVMs) and development system cards will support concurrent engineering. Together, PE, Code Warrior and EVMs create a complete, scalable tools solution for easy, fast, and efficient development.
