C8051T620/2-DK 7.1. System Clock Sources The C8051T62x/32x devices feature a calibrated internal oscillator that is enabled as the system clock source on reset. After reset, the internal oscillator operates at a frequency of 48 MHz (±1.5%) by default but may be configured by software to operate at other frequencies. Therefore, in many applications, an external oscillator is not required. However, if you wish to operate the C8051T62x/32x device at a frequency not available with the internal osci

C8051T620/2-DK 7.8. Analog I/O (J1 and J14) Three of the C8051T62x/32x 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 3 for the J1 terminal block connections. Placing a shorting block on J14 will connect the P0.7/VREF signal on J1 to the P0.7 pin of the device. Table 3. J1 Terminal Block Descriptions Pin # Description 1VREGIN 2VIO 3GND 4 P2.5 (An

C8051T620/2-DK 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 Volta
