10.3 Power supply rise time
The minimum rise time of the power supply on the LPC55S69/S28 does not meet the
power-up ramp conditions specified in the datasheet. Please see the data sheet and
VBAT_DCDC.1 errata in the errata sheet.
11. Board operating conditions
These boards have been designed for use in laboratory conditions (0 to 50 degrees
Celsius) and should not be used for extended temperature testing. Refer to the data sheet
of the LPC55xx MCU being used for full operating conditions for that device.
