General operating conditions

Figure 131. fCPU max versus VDD

Note:

Some temperature ranges are only available with a specific package and memory size.

Refer to Section 14.2: Device ordering information and transfer of customer code on

page 358.

Warning:

Do not connect 12V to VPP before VDD is powered on, as this may damage

the device.
