MC9S08QE64CFT Description

The MC9S08QE64CFT MCU is from the MC9S08QE128 Series based on  8-Bit HCS08 Central Processor Unit (CPU).

MC9S08QE64CFT 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 a temperature range of –40 degree to 85 degree

– 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 the run, wait and stop modes to provide an accurate clock source to a 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 per cent resolution and 2 per cent deviation over temperature and voltage; supports CPU frequencies from 4 kHz to 50.33 MHz.
