NXP MC9S08QE128CLH

MC9S08QE128CLH                            Description

A microcontroller (MCU for microcontroller unit) is a small computer on a single VLSI integrated circuit (IC) chip. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals.

MC9S08QE128CLH                          Features

? 8-Bit HCS08 Central Processor Unit (CPU)

? Up to 50.33-MHz HCS08 CPU above 2.4V, 40-MHz

CPU above 2.1V, and 20-MHz CPU above 1.8V, across

temperature range

? HC08 instruction set with added BGND instruction

? Support for up to 32 interrupt/reset sources

? On-Chip Memory

? Flash read/program/erase over full operating voltage

and temperature

? Random-access memory (RAM)

? Security circuitry to prevent unauthorized access to

RAM and flash contents

? Power-Saving Modes

? Two low power stop modes; reduced power wait mode

? Peripheral clock enable register can disable clocks to

unused modules, reducing currents; allows clocks to

remain enabled to specific peripherals in stop3 mode

? Very low power external oscillator can be used in stop3

mode to provide accurate clock to active peripherals

? Very low power real time counter for use in run, wait,

and stop modes with internal and external clock sources

? 6 ?s typical wake up time from stop modes

? Clock Source Options

? Oscillator (XOSC) ? Loop-control Pierce oscillator;

Crystal or ceramic resonator range of 31.25 kHz to

38.4 kHz or 1 MHz to 16 MHz

? Internal Clock Source (ICS) ? FLL controlled by

internal or external reference; precision trimming of

internal reference allows 0.2% resolution and 2%

deviation; supports CPU freq. from 2 to 50.33 MHz

? System Protection

? Watchdog computer operating properly (COP) reset

with option to run from dedicated 1-kHz internal clock

source or bus clock

? Low-voltage detection with reset or interrupt; selectable

trip points

? Illegal opcode detection with reset

? Flash block protection

? Development Support

? Single-wire background debug interface

? Breakpoint capability to allow single breakpoint setting

during in-circuit debugging (plus two more breakpoints)

? On-chip in-circuit emulator (ICE) debug module

containing two comparators and nine trigger modes.

MC9S08QE128CLH                      Applications

? Analog and digital sensor systems

? Data loggers

? Connectivity to USB hosts
