Features

? 8-Bit S08 Central Processor Unit (CPU)

– Up to 40 MHz CPU at 2.7 V to 5.5 V across temperature range of –40 °C to 125 °C

– HC08 instruction set with added BGND instruction

– Support for up to 32 interrupt/reset sources

? On-Chip Memory

– 4 KB flash read/program/erase over full operating voltage and temperature

– 128-byte 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

– Allows clocks to remain enabled to specific peripherals in stop3 mode

? Clock Source Options

– 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 1 deviation over 0–70 °C and voltage, 2 deviation over –40–85 °C and voltage, or 3 deviation over –40–125 °C and voltage; supporting bus frequencies up to 20 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

– 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 two more breakpoints)

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