Features

? 8-bit HCS08 Central Processor Unit (CPU)

¨C Up to 40 MHz CPU at 5.5 V to 2.7 V across temperature range of ¨C40 ¡ãC to 85 ¡ãC and ¨C40 ¡ãC to 105 ¡ãC

¨C HCS08 instruction set with added BGND instruction

¨C Support for up to 32 interrupt/reset sources

? On-Chip Memory

¨C 32 KB or 18 KB dual array flash; read/program/erase over full operating voltage and temperature

¨C 1984 byte random access memory (RAM)

¨C Security circuitry to prevent unauthorized access to RAM and flash contents

? Power-Saving Modes

¨C Two low-power stop modes (stop2 and stop3)

¨C Reduced-power wait mode

¨C Peripheral clock gating register can disable clocks to unused modules, thereby reducing currents

¨C Low power on-chip crystal oscillator (XOSC) that can be used in low-power modes to provide accurate clock source to real time counter and LCD controller

¨C 100 ¦Ìs typical wakeup time from stop3 mode

? Clock Source Options

¨C Oscillator (XOSC) ¡ª Loop-control Pierce oscillator; crystal or ceramic resonator range of 31.25 kHz to 38.4 kHz or 1 MHz to 16 MHz

¨C Internal Clock Source (ICS) ¡ª 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 bus frequencies from 1 MHz to 20 MHz.

? System Protection

¨C COP reset with option to run from dedicated 1 kHz internal clock or bus clock

¨C Low-voltage warning with interrupt

¨C Low-voltage detection with reset

¨C Illegal opcode detection with reset

¨C Illegal address detection with reset

¨C Flash and RAM protection

? Development Support

¨C Single-wire background debug interface

¨C Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints

in on-chip debug module)
