• The datasheet mentions the I/O pins are 5V tolerant if Vdd is present. Can you explain in detail what this implies?

    The IO pin will be 5V tolerant if the supply voltage Vdd is present, and they are configured as inputs. VDDIO must be applied to the microcontroller when input voltage is 5V, or else the 5V tolerance does not apply. &...

  • How to calculate the value of crystal load capacitors?

    The following formula may be used to calculate a parallel resonant crystal's external load capacitors: CL = ((CX1 x CX2) / (CX1 + CX2)) + Cstray where: CL = the crystal load capacitance Cstray = the stray capacitance ...

  • After a software reset like WD reset, BOD reset, is the SRAM content retained?

    Yes. In case of a software reset like WD reset, BOD reset etc, the SRAM contents (memory address 0x1000 0000 to 0x1000 2000 in case of LPC1227 ) is retained. However, the part won't retain the contents if it goes to d...
