NXP MC9S08QE16CLC

S0850MHz16KB（16K x 8）

Overview

The MC9S08QE16CLC is a 8-bit Microcontroller based on enhanced HCS08 CPU (25MHz bus) with CISC architecture operates at a maximum frequency of 50MHz. The device incorporates 16kB internal flash, 1kB internal RAM, 10-channel 12-bit A/D converter and 26 general-purpose I/O pins. This device also features peripherals like one inter-integrated circuit (IIC) bus module to operate at up to 100kbps, one serial peripheral interface modules (SPI), two serial communications interface (SCI) and an analog comparator. Internal clock source (ICS) containing a frequency-locked-loop (FLL) controlled by internal or external reference, precision trimming of internal reference allowing 0.2% resolution and 2% deviation. Watchdog computer operating properly (COP) reset with option to run from dedicated 1kHz internal clock source.

Features

? 8-Bit HCS08 Central Processor Unit (CPU)

– Up to 50.33 MHz HCS08 CPU at 3.6 V to 2.4 V, 40 MHz CPU at 2.4

V to 2.1 V and 20 MHz CPU at 2.1 V to 1.8 V across temperature

range of –40 °C to 85 °C

– 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 very low power stop modes

– Reduced power wait mode

– Peripheral clock enable register can disable clocks to unused

modules, thereby reducing currents; allows clocks to remain enabled

to specific peripherals in stop3 mode.

– Very low power external oscillator that can be used in run, wait, and

stop modes to provide accurate clock source to real time counter.

– 6 ms typical wakeup time from stop3 mode

? Clock Source Options

– Oscillator (XOSCVLP) — 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) — Internal clock source module

containing a frequency-locked-loop (FLL) controlled by internal or

external reference; precision trimming of internal reference allows

0.2% resolution and 2% deviation over temperature and voltage;

supports CPU frequencies from

4 kHz 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 warning with interrupt.

– Low-voltage detection with reset or interrupt

– Selectable trip points.

– Illegal opcode detection with reset

– Illegal address 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 three breakpoints in on-chip debug

Module

Applications

? Industrial applications: PLC, inverters, circuit breakers

? Printers, and scanners

? Alarm systems, video intercom, and HVAC

? Home audio appliances
