C8051F064-EK
9.1. System Clock Sources
The C8051F064 device installed on the evaluation board features a calibrated programmable internal oscillator
that is enabled as the system clock source on reset. After reset, the internal oscillator operates at a frequency of
3.0625 MHz (±2%) by default but may be configured by software to operate at other frequencies. Therefore, in
many applications, an external oscillator is not required. However, an external 22.1184 MHz crystal is installed on
the evaluation board for additional applications. Refer to the C8051F06x data sheet for more information on
configuring the system clock source.
9.2. Switches and LEDs
Two switches are provided on the evaluation board. Switch SW1 is connected to the RESET pin of the C8051F064.
Pressing SW1 puts the device into its hardware-reset state. Switch SW2 is connected to the C8051F060’s general-
purpose I/O (GPIO) pin P3.7. Pressing SW2 generates a logic low signal on the port pin.
Four LEDs are also provided on the evaluation board.
D1—The bi-color LED labeled “Run/Stop” indicates communications between the PC and the DEBUG USB port.
D2—The red LED D2 reflects the state of the SUSPEND signal of the DATA port device.
D3—The green LED labeled “P1.6” is connected to the C8051F064’s GPIO pin P1.6.
D4—The red LED labeled “PWR” indicates a power connection to the evaluation board.
9.3. DEBUG Interface (J1)
The evaluation board DEBUG USB port (J1) provides the interface between a PC USB port and the C8051F064’s
in-system debug/programming circuitry. In addition, this port is used for the ADC Demo detailed in Section 4.

9.4. DATA Interface (J7)
The evaluation board DATA USB port (J7) provides a data interface between a PC USB port and the CP2101
(Silicon Labs USB to UART bridge). This interface provides a virtual COM port via USB and will appear as a COM
port to PC applications.Table 2 shows the DATA USB pin definitions.
