56F8323 Technical Data, Rev. 11.0
8
Freescale Semiconductor
Preliminary
is 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. Each PWM is
double-buffered and includes interrupt controls to permit integral reload rates to be programmable from
1/2 (center-aligned mode only) to 16. The PWM module provides reference outputs to synchronize the
Analog-to-Digital Converters (ADCs) through Quad Timer C, Channel 2.
The 56F8323 incorporates one 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 alarm when no shaft motion is detected.
Each input is filtered to ensure only true transitions are recorded.
This hybrid controller also provides a full set of standard programmable peripherals that include two Serial
Communications Interfaces (SCIs), two Serial Peripheral Interfaces (SPIs), two Quad Timers, and
FlexCAN. Any of these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function
is not required. A Flex Controller Area Network (FlexCAN) interface (CAN Version 2.0 B-compliant) and
an internal interrupt controller are also a part of the 56F8323.
1.2.2
56F8123 Features
The 56F8123 hybrid controller includes 32KB of Program Flash, programmable through the JTAG port,
and 8KB of Data RAM. A total of 8KB of Boot Flash is incorporated for easy customer inclusion of
field-programmable software routines that can be used to program the main Program Flash memory area.
The Program Flash memory can be independently bulk erased or erased in pages; Program Flash page
erase size is 1KB. The Boot Flash memory can also be either bulk or page erased.
This hybrid 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 56F8123.
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), demonstration board kit 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.
