Clock Sources
•
•
Provides breakpoints, single stepping
Inspect/modify memory and registers
•
Precision internal oscillators: 24.5 MHz with ±2% accu-
racy supports UART operation; spread-spectrum mode
for reduced EMI; Low power 20 MHz internal oscillator
High-Speed 8051 µC Core
•
Pipelined instruction architecture; executes 70% of instruc-
tions in 1 or 2 system clocks
•
•
External oscillator: Crystal, RC, C, CMOS clock
SmaRTClock oscillator: 32.768 kHz crystal or self-
oscillate
Can switch between clock sources on-the-fly; useful in
power saving modes and in implementing various power
saving modes
