Absolute Maximum Ratings
Operating beyond the functional operating temperature range (Table 21) is not recommended and
extended exposure beyond the functional operating temperature range may affect reliability.
Table 23 lists the functional operating voltage range.
Warning:
Under all operating conditions, the 3.3 V – 1.35/1.3/1.2 V and 3.3 V – 2.5 V supply voltage
difference (Vdelta) must not be exceeded; otherwise, permanent damage to the device may result.
Also, the Core/PLL supply voltage must never be less than 1.1 V (refer to Table 20).
