(1) TI recommends powering AVCC and DVCC pins from the same source. At a minimum, during power up, power down, and device operation, the voltage difference between AVCC and DVCC must not exceed the limits specified in
Absolute Maximum Ratings. Exceeding the specified limits may cause malfunction of the device including erroneous writes to RAM and FRAM.
(2) See
Table 5-1 for additional important information.
(3) Modules may have a different supply voltage range specification. See the specification of the respective module in this data sheet.
(4) Connect a low-ESR capacitor with at least the value specified and a maximum tolerance of 20% as close as possible to the DVCC pin.
(5) Modules may have a different maximum input clock specification. See the specification of the respective module in this data sheet.
(6) The minimum supply voltage is defined by the supervisor SVS levels. See
Table 5-2 for the values.
(7) Wait states only occur on actual FRAM accesses; that is, on FRAM cache misses. RAM and peripheral accesses are always executed without wait states.
(8) DCO settings and HF crystals with a typical value less or equal the specified MAX value are permitted.
(9) DCO settings and HF crystals with a typical value less or equal the specified MAX value are permitted. If a clock sources with a larger typical value is used, the clock must be divided in the clock system.
