, 3
2
Typical power is based on a voltage of Vdd = 1.2 V, a junction temperature of TJ = 105°C, and a Dhrystone benchmark
application.
3
Thermal solutions may need to design to a value higher than typical power based on the end application, TA target, and I/O
power.
Maximum 4
4
Maximum Power is based on a voltage of Vdd = 1.2 V, worst case process, a junction temperature of TJ = 105°C, and an
artificial smoke test.
