MC9S08QE32CLD                    Description

 The 8-bit microcontroller architecture is simpler and has an easy to understand programming model. It usually needs just a single supply. Despite marketing claims to the contrary, modern 8-bit architectures are lower power compared to 32-bit because the innards toggle fewer bus signals.

MC9S08QE32CLD                              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)
