NXP MC9S08QE32CLC

S0850 МГц32 КБ (32К x 8)

Overview

The MC9S08QE32CLC 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 32kB internal flash, 2kB 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 Vto 2.4 V40MHz CPU

at 2.4 V to 2.1 V and 20 MHz CPU at 2.1Vto1.8Vacross temperature range of-40°C to85°C

-HC08 instruction set with added BGNDinstruction -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 runwait

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

- 6us typical wake up time from stop3 mode Clock Source Options

-Oscillator(XOSCVLP)-Loop-controlPierce oscillator:

crvstal or ceramic resonator range of31.25 kHz to 38.4 kHz o11 MHz to 16 MHz

-Internal clock source(Ics)-Internal clock source module

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

internal or externalreferenceprecision trimming ofinterna reference allows 0.2%resolution and 2%deviation over temperature and voltagesupports CPU frequencies from4kHz to 50.33 MHz System Protection

-Watchdog computer operating properly(COPreset withoption

to run from dedicated 1 kHz internal clock source or bus clock -Low-voltage warning with interrupt.

Applications
