7.10. Using Alternate Supplies with the C8051T62x Development Kit
For most evaluation purposes, the onboard 3.3 V supply regulator is sufficient to be used as a VDD power supply. However, in applications where a different supply voltage is desired (e.g., 1.8 V), an external supply voltage can be applied to the board at the analog connector (J1). Some devices in the C8051T62x/32x family also support a separate voltage input for the input/output voltage of the port pins. This Voltage Input/Output (VIO) should be input to J1 on Pin 2. See the
Notes:
When programming a C8051T62x/32x device, VDD must be at least 3.3 V. VDD can be supplied directly to the device, or the
If an external supply voltage is desired, the shorting block on J6 should be placed so that the Pin 3 (VDD_EXT) is shorted to Pin 4 (VDD_PWR).
