7.7. PORT I/O Connectors (J2, J3 and J4)
Each of the C8051T63x's I/O pins, as well as +3VD and GND, are routed to headers J2 through J4. J2 connects to
the microcontroller's Port 0 pins, J3 connects to Port 1, and J4 connects to Port 2.
7.8. Analog I/O (J1)
Three of the C8051T63x target device's port pins are connected to the J1 terminal block. The terminal block also
allows users to input an external voltage that can be used as the power supply of the board. Refer to Table 2 for the
J1 terminal block connections.
7.9. VPP Connection (J11)
The C8051T63x devices require a special 6.5 V programming voltage applied to the VPP pin during device
programming. The VPP pin on these devices is shared with P0.2. During programming, the VPP voltage is
automatically enabled when needed. Header J11 is provided to allow the user to disconnect the programming
circuitry from the VPP/P0.2 pin to avoid interfering with the normal application operation of P0.2. When
programming the device, J11 should be shorted with a shorting block. When running normal application code, J11
can be removed.
7.10. Using Alternate Supplies with the C8051T63x 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).
Notes:
1. When programming a C8051T63x device, the onboard 3.3 V regulator should be used for VDD.
2. 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).
