CPU characteristics

Working voltage:
FSYS = 4 MHz: 2.2 V to 5.5 V
FSYS = 8 MHz: 3.0 V-5.5 V fSYS = 12 MHz: 4.5 V to 5.5 V
In the VDD = 5 V, the system frequency for 12 MHz, instruction cycle for 0.33 μ s
Sleep mode and sensei function can reduce power consumption
Oscillation mode: external high frequency crystals-HXT external RC-ERC internal high frequency RC-HIRC external low frequency crystals-LXT

3 working pattern: normal mode, low speed mode, sleep mode
Internal integration 4 MHz, 8 MHz and 12 MHz oscillator, do not need to increase external components
