MC9S08LL16主要特性:
• 8-Bit HCS08 Central Processor Unit (CPU)
– Up to 20-MHz CPU at 3.6V to 1.8V across temperature range of -40℃ to 85℃
– HC08 instruction
setwith 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 o
scillator 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) control
ledby 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.
