(1) TI recommends powering the AVCC, DVCC, PVCC pins from the same source. At a minimum, during power up, power down, and device operation, the voltage difference among AVCC, DVCC, PVCC must not exceed the limits specified in Absolute Maximum Ratings. Exceeding the specified limits can cause malfunction of the device including erroneous writes to RAM and FRAM.
(2) The USS module must be disabled if AVCC and DVCC are lower than 2.2 V.
(3) Fast supply voltage changes can trigger a BOR reset even within the recommended supply voltage range. To avoid unwanted BOR resets, the supply voltage must change by less than 0.05 V per microsecond (±0.05 V/µs). Following the recommendation for capacitor CDVCC should limit the slopes accordingly.
(4) Modules may have a different supply voltage range specification. See the specification of the respective module in this data sheet.
(5) As a decoupling capacitor for each supply pin pair (DVCC and DVSS or AVCC and AVSS), place a low-ESR 100-nF (minimum) ceramic capacitor as close as possible (within a few millimeters) to the respective pin pairs. For the PVCC and PVSS pair, place a low-ESR 22-µF (minimum) ceramic capacitor as close as possible (within a few millimeters) to the pin pair.
(6) Modules may have a different maximum input clock specification. See the specification of each module in this data sheet.
(7) The minimum supply voltage is defined by the supervisor SVS levels. See the PMM SVS threshold parameters for the exact values.
(8) Wait states occur only on actual FRAM accesses; that is, on FRAM cache misses. RAM and peripheral accesses are always excecuted without wait states.
(9) DCO settings and HF crystals with a typical value less than or equal to the specified MAX value are permitted.
(10) DCO settings and HF crystals with a typical value less than or equal to the specified MAX value are permitted. If a clock source with a higher typical value is used, the clock must be divided in the clock system.
