Digital Signal Controller

Freescale Semiconductor 

Overview

— On-chip relaxation oscillator with two user selectable frequencies: 400 kHz for low speed mode, 8 MHz for

normal operation

— On-chip low-power 1 kHz oscillator can be selected as clock source to the RTC and/or COP

— External clock: crystal oscillator, ceramic resonator, and external clock source

• Power management controller (PMC)

— On-chip regulator for digital and analog circuitry to lower cost and reduce noise

— Integrated power-on reset (POR)

— Low-voltage interrupt with a user selectable trip voltage of 1.81 V or 2.31 V

— User selectable brown-out reset

— Run, wait, and stop modes

— Low-power run, wait, and stop modes

— Partial power down mode

• Up to 40 general-purpose I/O (GPIO) pins

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

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

— Hysteresis and configurable pullup device on all input pins

— Configurable slew rate and drive strength and optional input low pass filters on all output pins

— 20 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

3.1.6 Power Saving Features

• Three low power modes

— Low-speed run, wait, and stop modes: 200 kHz IP bus clock provided by ROSC

— Low-power run, wait, and stop modes: clock provided by external 32–38.4 kHz crystal

— Partial power down mode

• Low power external oscillator can be used in any low-power mode to provide accurate clock to active peripherals

• Low power real time counter for use in run, wait, and stop modes with internal and external clock sources

• 32 μs typical wakeup time from partial power down modes

• Each peripheral can be individually disabled to save power

3.2 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), demonstration board kit, and development system cards support concurrent

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

development.

A full set of programmable peripherals — PWM, PGAs, ADCs, SCI, SPI, I2C, PIT, timers, and analog comparators — supports

various applications. Each peripheral can be independently shut down to save power. Any pin in these peripherals can also be

used as general-purpose input/outputs (GPIOs).
