Notes:
1. The values do not include I/O supply power (OVDD, LVDD, GVDD) or AVDD.
2. Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site (board)
temperature, ambient temperature, air flow, power dissipation of other components on the board, and board thermal
resistance. Any customer design must take these considerations into account to ensure the maximum 105 degrees junction
temperature is not exceeded on this device.
3. Typical power is based on a nominal voltage of VDD = 1.2V, a nominal process, a junction temperature of Tj = 105° C, and a
Dhrystone 2.1 benchmark application.
4. Thermal solutions likely need to design to a value higher than Typical Power based on the end application, TA target, and I/O
power
5. Maximum power is based on a nominal voltage of VDD = 1.2V, worst case process, a junction temperature of Tj = 105° C, and
an artificial smoke test.
6. The nominal recommended VDD = 1.3V for this speed grade.
