9 / 172 page  Award-Winning Development Environment 56F8365 Technical Data, Rev. 6.0 Freescale Semiconductor 9 Preliminary programmable to support a continuously variable PWM frequency. Edge-aligned and center-aligned synchronous pulse width control (0% to 100% modulation) is 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 PWM incorporates fault protection and cycle-by-cycle current limiting with sufficient output drive capability to directly drive standard optoisolators. A “smoke-inhibit”, write-once protection feature for key parameters is also included. A patented PWM waveform distortion correction circuit is also provided. The PWM is double-buffered and includes interrupt controls to permit integral reload rates to be programmable from 1 to 16. The PWM module provides reference outputs to synchronize the Analog-to-Digital Converters through two channels of Quad Timer C. The 56F8165 incorporates a Quadrature Decoder capable of capturing all four transitions on the two-phase inputs, permitting generation of a number proportional to actual position. Speed computation capabilities accommodate both fast- and slow-moving shafts. An integrated watchdog timer in the Quadrature Decoder can be programmed with a time-out value to alert when no shaft motion is detected. Each input is filtered to ensure only true transitions are recorded. This controller also provides a full set of standard programmable peripherals that include two Serial Communications Interfaces (SCIs); two Serial Peripheral Interfaces (SPIs); and two Quad Timers. Any of these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function is not required. An internal interrupt controller is also a part of the 56F8165. 1.3 Award-Winning 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 CodeWarrior 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, CodeWarrior and EVMs create a complete, scalable tools solution for easy, fast, and efficient development. |
