47.1 Operating Frequencies and Thermal Limitations

Table 47-1. Operating Frequency vs. Voltage
Characteristic VDDIO, VDDIN, AVDD Range Temp. Range (in °C) Max CPU Frequency Comments
DC_7 2.7 to 5.5V (1, 2, 3) -40°C to +125°C 48 MHz Extended
Note:
  1. With BODVDD disabled. If the BODVDD is enabled, refer to parameter REG_47.
  2. The same voltage must be applied to VDDIN and AVDD. This common voltage is referred to as VDD in the data sheet. VDDIO must be lower or equal to VDD = VDDIN = AVDD.
  3. Some I/Os are in the VDDIO cluster, but can be multiplexed as analog functions (inputs or outputs). In such a case, AVDD is used to power the I/O. Using this configuration may result in an electrical conflict if the VDDIO voltage is lower than VDD = VDDIN = AVDD.
