Hot-selling and scarce MC9S08QE128CLK 8-Bit HCS08 Central Processor Unit (CPU) QFP spot stock

Product Features

• 8-Bit HCS08 Central Processor Unit (CPU)

– Up to 50.33-MHz HCS08 CPU from 3.6V to 2.1V, and 20-MHz CPU at 2.1V to 1.8V across temperature range

– 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

– Peripheral clock enable register can disable clocks to unused modules, reducing currents; allows clocks to remain enabled to specific peripherals in stop3 mode

– Very low power external oscillator can be used in stop3 mode to provide accurate clock to active peripherals

– Very low power real time counter for use in run, wait, and stop modes with internal and external clock sources

– 6 μs typical wake up time from stop modes

• 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) — FLL controlled by internal or external reference; precision trimming of internal reference allows 0.2% resolution and 2% deviation; supports CPU freq. from 2 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 detection with reset or interrupt; selectable trip points

– Illegal opcode 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 two more breakpoints)

– On-chip in-circuit emulator (ICE) debug module containing two comparators and nine trigger modes.
