5.1. System Clock Sources

The C8051F360 device installed on the target board features a calibrated programmable internal oscillator which is

enabled as the system clock source on reset. After reset, the internal oscillator operates at a frequency of

3.0625 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 C8051F360 device at a

frequency not available with the internal oscillator, an external crystal may be used. Refer to the C8051F36x data

sheet for more information on configuring the system clock source.

The target board is designed to facilitate the installation of an external crystal. Remove shorting blocks at headers

J10 and J11 and install the crystal at the pads marked Y1. Install a 10 Mresistor at R1 and install capacitors at

C20 and C19 using values appropriate for the crystal you select. Refer to the C8051F36x data sheet for more

information on the use of external oscillators.

5.2. Switches and LEDs

Three switches are provided on the target board. Switch RESET is connected to the RESET pin of the C8051F360.

Pressing RESET puts the device into its hardware-reset state. Switches P3.0 and P3.1 are connected to the

C8051F360’s general purpose I/O (GPIO) pins through headers. Pressing P3.0 or P3.1 generates a logic low

signal on the port pin. Remove the shorting blocks from the J12 header to disconnect Switch P3.0 and Switch P3.1

from the port pins. See Table 1 for the port pins and headers corresponding to each switch.

Four LEDs are also provided on the target board. The red LED labeled PWR is used to indicate a power

connection to the target board. The green surface-mount LEDs labeled with port pin names are connected to the

C8051F360’s GPIO pins through headers. Remove the shorting blocks from the header to disconnect the LEDs

from the port pin. The USB ACTIVE red LED indicates when the CP210x USB-to-UART bridge (U3) on the board is

receiving power from the USB bus and is properly enumerated (i.e. drivers are installed and a USB cable is

connected to P4). See Table 1 for the port pins and headers corresponding to each LED.

Also included on the C8051F360 target board is a 10 Kthumb-wheel rotary potentiometer, part number R10. The

potentiometer is connected to the C8051F360’s P2.5 pin through the J13 header. Remove the shorting block from

the header to disconnect the potentiometer from the port pin. See Table 1 for the port pin and header

corresponding to the potentiometer.

5.3. PORT I/O Connectors (J2 - J6)

In addition to all port I/O signals being routed to the 96-pin expansion connector, each of the five parallel ports of

the C8051F360 has its own 10-pin header connector. Each connector provides a pin for the corresponding port

pins 0–7, +3.3 VDC and digital ground. Table 3 defines the pins for the port connectors, where Pn represents P0

through P4. The same pin-out order is used for all of the port connectors.

5.4. Target Board DEBUG Interface (J9)

The

DEBUG

connector (J9) provides access to the

DEBUG

(C2) pins of the C8051F360. It is used to connect the

Serial Adapter or the USB Debug Adapter to the target board for in-circuit debugging and Flash programming.

5.5. USB to Serial Connector (P1)

A USB-to-Serial bridge interface is provided. A USB B-type connector (P1), a Silicon Laboratories CP2102 USB-to-

UART Bridge, and related circuits are provided to facilitate the serial connection between a PC and the C8051F360

microcontroller on the target board. The RX, TX, CTS and RTS signals of the UART side of the Bridge (CP2102)

may be connected to the microcontroller by installing shorting blocks on J12 as follows:

5.6. Analog I/O (P2)

Several of the C8051F360 target device’s port pins are connected to the P3 terminal block. Refer to Table 5 for the

P3 terminal block connections.

5.7. Power Connector (J1)

The Target Board can be powered from three different sources: 1) The regulator input from the P2 9 V DC Power

Adapter, 2) The 5 V VBUS signal if P4 is connected to a USB bus, and 3) The 5 V USB bus if a USB Debug

Adapter is connected to the Debug Header (J9). Place a shorting block at header J1[REG_IN-P1_PWR] to power

the board directly from an AC/DC Power Adapter. Place a shorting block at header J1[REG_IN-VBUS] to power the

board from the USB bus connected to P4. Place a shorting block at header J1[REG_IN-SER_PWR] to power the

board from the USB Debug Adapter. Please note that the second option is not supported if a USB bus is not

connected to P4 and the third option is not supported with either the EC1 or EC2 Serial Adapters.

Note: Only one power option should be selected at one time.
