Digital Signal Controller

Freescale Semiconductor 

Overview

• Up to 54 general-purpose I/O (GPIO) pins

— 5 V tolerant I/O

— Individual control for each pin to be in peripheral or GPIO mode

— Individual input/output direction control for each pin in GPIO mode

— Individual control for each output pin to be in push-pull mode or open-drain mode

— Hysteresis and configurable pullup device on all input pins

— Ability to generate interrupt with programmable rising or falling edge and software interrupt

— Configurable drive strength: 4 mA / 8 mA sink/source current

• JTAG/EOnCE debug programming interface for real-time debugging

— IEEE 1149.1 Joint Test Action Group (JTAG) interface

— EOnCE interface for real-time debugging

2.1.6 Power Saving Features

• Low-speed run, wait, and stop modes: as low as 781 Hz clock provided by OCCS and internal ROSC

• Large regulator standby mode available for reducing power consumption at low-speed mode

• Less than 30 µs typical wakeup time from stop modes

• Each peripheral can be individually disabled to save power

2.2 Award-Winning Development Environment

Processor Expert (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 (IDE) is a sophisticated tool for code navigation, compiling, and

debugging. A complete set of evaluation modules (EVMs), demonstration board kit, and development system cards supports

concurrent engineering. Together, PE, CodeWarrior, and EVMs create a complete, scalable tools solution for easy, fast, and

efficient development.

2.3 Architecture Block Diagram

The MC56F825x/MC56F824x’s architecture appears in Figure 1 and Figure 2. Figure 1 illustrates how the 56800E system

buses communicate with internal memories and the IP bus interface as well as the internal connections among the units of the

56800E core.
