Questions about this item
How does the 20 MHz clock speed affect real-world throughput in an embedded design?
The 20 MHz rating sets the maximum instruction cycle rate, so tight loops and interrupt latency scale directly with that frequency.
What does the TQFP-44 package determine for board integration?
The TQFP-44 package fixes the physical footprint and provides 44 pins for power, ground and I/O connections on the PCB.
