56F8346 Technical Data
Preliminary
provides two external dedicated interrupt lines and up to 62 General Purpose Input/Output (GPIO)
lines, depending on peripheral configuration.
The 56F8346 hybrid controller includes 128KB of Program Flash and 8KB of Data Flash (each
programmable through the JTAG port) with 4KB of Program RAM and 8KB of Data RAM. It also
supports program execution from external memory.
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 and Data Flash memory areas.
Both Program and Data Flash memories can be independently bulk erased or erased in pages.
Program Flash page erase size is 1KB. Boot and Data Flash page erase size is 512 bytes. The Boot
Flash memory can also be either bulk or page erased.
A key application-specific feature of the 56F8346 is the inclusion of two Pulse Width Modulator
(PWM) modules. These modules each incorporate three complementary, individually
programmable PWM signal output pairs (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-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 PWMs incorporate 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 to 16. The PWM modules provide reference outputs to synchronize the Analog-to-Digital
Converters through two channels of Quad Timer C.
The 56F8346 incorporates two 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. 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 hybrid controller also provides a full set of standard programmable peripherals that include
two Serial Communications Interfaces (SCIs); two Serial Peripheral Interfaces (SPIs); and four
Quad Timers. 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 a part of the 56F8346.
1.3 Award-Winning Development Environment
Processor Expert
TM
(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.
