com MC9S08QE8 MC9S08QE8 Series Covers: MC9S08QE8 and MC9S08QE4 Features • 8-Bit HCS08 Central Processor Unit (CPU) – Up to 20 MHz CPU at 3.
6 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 low power stop modes – Reduced power wait mode – Low power run and wait modes allow peripherals to run while voltage regulator is in standby – Peripheral clock gating register can disable clocks to unused modules, thereby reducing currents – Very low power external oscillator that can be used in stop2 or stop3 modes to provide accurate clock source to real time counter – 6 μs typical wake-up time from stop3 mode • 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) — 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; supporting bus frequencies from 1 MHz to 10 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 – 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 sett...
