, 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 will likely 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.
