1.2 Device Description
The 56F8355 and 56F8155 are members of the 56800E core-based family of controllers. It combines, on
a single chip, the processing power of a Digital Signal Processor (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 56F8355 and 56F8155 are
well-suited for many applications. The devices include many peripherals that are especially useful for
motion control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and
control, automotive control (56F8355 only), engine management, noise suppression, remote utility
metering, industrial control for power, lighting, and automation applications.
The 56800E 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 MCU-style programming model and
optimized instruction set allow straightforward generation of efficient, compact DSP and control code.
The instruction set is also highly efficient for C/C++ Compilers to enable rapid development of optimized
control applications.
The 56F8355 and 56F8155 support program execution from internal memories. Two data operands can be
accessed from the on-chip data RAM per instruction cycle. These devices also provide two external
dedicated interrupt lines and up to 49 General Purpose Input/Output (GPIO) lines, depending on peripheral
configuration.
1.2.1 56F8355 Features
The 56F8355 controller includes 256KB of Program Flash and 8KB of Data Flash (each programmable
through the JTAG port) with 4KB of Program RAM and 16KB of Data RAM. A total of 16KB 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
56F8355 Technical Data, Rev. 8.0
Freescale Semiconductor 7
Preliminary
be independently bulk erased or erased in page sizes. 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 56F8355 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 a reference output to
synchronize the Analog-to-Digital Converters through two channels of Quad Timer C.
The 56F8355 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 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 included on the 56F8355.
1.2.2 56F8155 Features
The 56F8155 controller includes 256KB of Program Flash, programmable through the JTAG port, and
16KB of Data RAM. A total of 16KB 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 page erase size is 512 bytes; Boot Flash memory can also be either bulk
or page erased.
A key application-specific feature of the 56F8155 is the inclusion of one Pulse Width Modulator (PWM)
module. This module incorporates three complementary, individually programmable PWM signal output
pairs and can also support six independent PWM functions to enhance motor control functionality.
Complementary operation permits programmable dead time insertion, distortion correction via current

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 56F8155.
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.

1.4 Architecture Block Diagram
Note: Features in italics are NOT available in the 56F8155 device and are shaded in the following figures.
The 56F8355/56F8155 architecture is shown in Figure 1-1 and Figure 1-2. Figure 1-1 illustrates how the
56800E system buses communicate with internal memories and the IP Bus Bridge. Table 1-1 lists the
internal buses in the 56800E architecture and provides a brief description of their function. Figure 1-2
shows the peripherals and control blocks connected to the IP Bus Bridge. The figures do not show the
on-board regulator and power and ground signals. They also do not show the multiplexing between
peripherals or the dedicated GPIOs. Please see Part 2, Signal/Connection Descriptions, to see which
signals are multiplexed with those of other peripherals.
Also shown in Figure 1-2 are connections between the PWM, Timer C and ADC blocks. These
connections allow the PWM and/or Timer C to control the timing of the start of ADC conversions. The
Timer C channel indicated can generate periodic start (SYNC) signals to the ADC to start its conversions.
In another operating mode, the PWM load interrupt (SYNC output) signal is routed internally to the Timer
C input channel as indicated. The timer can then be used to introduce a controllable delay before
generating its output signal. The timer output then triggers the ADC. To fully understand this interaction,
please see the 56F8300 Peripheral User Manual for clarification on the operation of all three of these
peripherals.

2.2 Signal Pins
After reset, all pins are by default the primary function. Any alternate functionality must be programmed.
EMI is not functional in this package; since only part of the address/data bus is bonded out, use as GPIO
pins.
Note: Signals in italics are NOT available in the 56F8155 device.
If the “State During Reset” lists more than one state for a pin, the first state is the actual reset state. Other
states show the reset condition of the alternate function, which you get if the alternate pin function is
selected without changing the configuration of the alternate peripheral. For example, the A8/GPIOA0 pin
shows that it is tri-stated during reset. If the GPIOA_PER is changed to select the GPIO function of the
pin, it will become an input if no other registers are changed.
