1.2.4 Unknown Programming Failures

Some devices are designed for specific power supply ranges. Unexpected behavior may occur if a microcontroller designed for 3.3V (LF variant) is used with a 5V supply, or vise-versa. The device data sheet will specify the operating supply range that the device can be used with.

Tip: Not all device families have special LF variants.
