MC9S08LL16集成電路（IC）的微控制器規(guī)格書PDF中文資料

Features

? 8-Bit HCS08 Central Processor Unit (CPU)

– Up to 20-MHz CPU at 3.6V to 1.8V 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

– Dual Array 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

– Low power run and wait modes allow peripherals to run while voltage regulator is in standby

– Peripheral clock gating register can disable clocks to unused modules, thereby reducing currents.

– Very low power external oscillator that can be used in stop2 or stop3 modes to provide accurate clock source to real time counter

– 6 usec typical wake up time from stop3 mode

? 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) — 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 1MHz 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 Warning with interrupt

– Low-Voltage Detection with reset or interrupt

– Illegal opcode and 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 in on-chip debug module)

? Input/Output

– 38 GPIOs, 2 output-only pins

– 8 KBI interrupts with selectable polarity

– Hysteresis and configurable pull up device on all input pins; Configurable slew rate and drive strength on all output pins.

? Package Options

– 64-LQFP, 48-LQFP and 48-QFN
