over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)

• (2) Voltage differences between DVCC and AVCC exceeding the specified limits may cause malfunction of the device.
• (3) All voltages referenced to V SS .

(4) Higher temperature may be applied during board soldering according to the current JEDEC J-STD-020 specification with peak reflow temperatures not higher than classified on the device label on the shipping boxes or reels.

Typical data are based on VCC = 3.0 V, TA = 25°C (unless otherwise noted)

• (2) Supply voltage must not change faster than 1 V/ms. Faster changes can cause the VCCDET to trigger a reset even within the recommended supply voltage range.
• (3) Modules may have a different supply voltage range specification. See the specification of the respective module in this data sheet.
• (4) Does not include I/O currents (driven by application requirements).
• (5) Operating frequency may require the flash to be accessed with wait states. See Section 5.8 for further details.
