16-Bit Digital Signal Controllers

Freescale Semiconductor 

— In the 56F8355, four dedicated general-purpose Quad Timers totaling six dedicated pins: Timer C with

two pins and Timer D with four pins

— In the 56F8155, two Quad Timers; Timer A and Timer C both work in conjunction with GPIO

• Optional On-Chip Regulator

• FlexCAN (CAN Version 2.0 B-compliant) module with 2-pin port for transmit and receive

• Two Serial Communication Interfaces (SCIs), each with two pins (or four additional GPIO lines)

• Up to two Serial Peripheral Interfaces (SPIs), both with configurable 4-pin port (or eight additional GPIO

lines); SPI 1 can also be used as Quadrature Decoder 1 or Quad Timer B

• Computer Operating Properly (COP)/Watchdog timer

• Two dedicated external interrupt pins

• 49 General Purpose I/O (GPIO) pins; 28 pins dedicated to GPIO

• External reset input pin for hardware reset

• External reset output pin for system reset

• Integrated low-voltage interrupt module

• JTAG/Enhanced On-Chip Emulation (OnCE) for unobtrusive, processor speed-independent, real-time

debugging

• Software-programmable, Phase Lock Loop-based frequency synthesizer for the core clock

1.1.5 Energy Information

• Fabricated in high-density CMOS with 5V-tolerant, TTL-compatible digital inputs

• On-board 3.3V down to 2.6V voltage regulator for powering internal logic and memories; can be disabled

• On-chip regulators for digital and analog circuitry to lower cost and reduce noise

• Wait and Stop modes available

• ADC smart power management

• Each peripheral can be individually disabled to save power

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.
