8-Bit S08 Central Processor Unit (CPU)
• Up to 20 MHz CPU at 4.5 V to 5.5 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
• Up to 8 KB flash read/program/erase over full operating voltage and temperature
• Up to 1024-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
• Oscillator (XOSC) — Loop-control Pierce oscillator; crystal or ceramic resonator range of 31.25 kHz to 39.0625 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; supports bus frequencies up 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 detectionwith 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.
Peripherals
• IPC — Interrupt priority controller to provide hardware based nested interrupt mechanism
• ADC — 12-channel, 8-bit resolution; 2.5 μs conversion time; automatic compare function; 1.7 mV/°C temperature sensor; internal bandgap reference channel; operation in stop; optional hardware trigger; fully functional from 4.5 V to 5.5 V
• TPM — One 4-channel and one 2-channel timer/pulse-width modulators (TPM) modules; selectable input capture, output compare, or buffered edge- or center-aligned PWM on each channel
• MTIM16 — One 16-bit modulo timer with optional prescaler
• SCI — One serial communications interface module with optional 13-bit break; LIN extensions
Input/Output
• 30 GPIOs including 1 output-only pin and 1 input-only pin
Package Options
• 32-pin SDIP
