Vi điều khiển CPU MC9S08FL8C 8kB Flash/ 1k RAM

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
