56F805 Technical Data, Rev. 16

Freescale Semiconductor
The 56F805 incorporates a total of 2K words of Boot Flash 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.
Key application-specific features of the 56F805 include the two Pulse Width Modulator (PWM) modules.
These modules each incorporate three complementary, individually programmable PWM signal outputs
(each module is also capable of supporting six independent PWM functions for a total of 12 PWM outputs)
to enhance motor control functionality. Complementary operation permits programmable dead time
insertion, distortion correction via current sensing by software, and separate top and bottom output polarity
control. The up-counter value is programmable to support a continuously variable PWM frequency. Edge-
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 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 and a patented PWM waveform distortion correction circuit are also provided. Each PWM
is double-buffered and includes interrupt controls to permit integral reload rates to be programmable from
1 to 16. The PWM modules provide a reference output to synchronize the ADCs.
The 56F805 incorporates two separate Quadrature Decoders 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. The 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 controller also provides a full set of standard programmable peripherals that include two Serial
Communications Interfaces (SCI), one Serial Peripheral Interface (SPI), and four Quad Timers. Any of
these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function is not required. A
Controller Area Network interface (CAN Version 2.0 A/B-compliant), an internal interrupt controller and
14 dedicated GPIO are also included on the 56F805.
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.
