The speed is not highly dependent upon the supply voltage. However, by limiting the temperature range, the speed can
be increased. The minimal guaranteed speed as a function of the supply voltage and maximal temperature operating
temperature is given below.

3. 100% RAM access
4. Typical software
Hints for low power operation:
1. Use the low power RAM instead of the RAM for all parameters that are accessed frequently. The average current
consumption for the low power RAM is about 40 times lower than for the RAM.
2. Rather than using the circuit at low speed, it is better to use the circuit at higher speed and switch off the blocks
when not needed.
3. The power consumption of the program memory is an important part of the overall power consumption.
