2. About the Daughter Boards

The C8051T620 and C8051T622 Development Kits include an Emulation Daughter Board (EDB) and a QFN

Socket Daughter Board (QFN-DB). The EDB has an installed C8051F34A device, which is a Flash-based device

that can be used for the majority of C8051T62x/32x code development. The QFN-DB is intended to allow both

programming and system-level debugging of C8051T62x/32x devices directly.

A C8051T62x/32x device cannot be erased once it has been programmed; so, it is advisable to use the

C8051F34A for the majority of code development. Refer to “AN368: Differences between the C8051F34A and the

C8051T62x and C8051T32x Device Families” for more details on how the C8051F34A can be used to develop

code for the C8051T62x/32x device families. Application notes can be found on the Silicon Labs web site:

The Silicon Labs 8-bit Development Tools download package available on that web page includes the Silicon

Laboratories Integrated Development Environment (IDE), 8051 evaluation toolset, Virtual COM Port drivers for the

CP210x USB to UART Bridge, and additional documentation. Download the package and install the components

by following the on-screen instructions.

4.1. System Requirements

The following are the system requirements necessary to run the debug and programming tools:

Pentium-class host PC running Microsoft Windows 2000 or newer.

One available USB port.

4.2. Development Tools Installation

To install the IDE, utilities, and code examples, perform the following steps:

1. Run the Silicon Labs 8-bit Development Tools installer downloaded from www.silabs.com/mcudownloads.

2. In the screen titled “Select Installation Packages”, the Silicon Labs IDE, 8051 Evaluation Toolset and CP210x

Virtual COM Port drivers will be checked by default. The programs necessary to download and debug on the

MCU are the Silicon Labs IDE and the 8051 Evaluation Toolset. The CP210x Drivers are necessary to use the

UART capabilities of the target board. See “4.3. CP210x USB to UART VCP Driver Installation” for more

information about installing the CP210x drivers. See “5. Software Overview” for an overview of all applicable

software included in the web download.

3. Installers selected in Step 3 will execute in sequence, prompting the user as they install programs,

documentation, and drivers.

4.3. CP210x USB to UART VCP Driver Installation

The C8051T62x Motherboard includes a Silicon Laboratories CP2103 USB-to-UART Bridge Controller. Device

drivers for the CP2103 need to be installed before PC software, such as HyperTerminal, can communicate with the

board over the USB connection. If the “Install CP210x Drivers” option was selected during installation, this will

launch a driver “unpacker” utility.

1. Follow the steps to copy the driver files to the desired location. The default directory is C:\SiLabs\MCU\CP210x.

2. The final window of this installer will provide an option to install the driver on the target system. Select the

“Launch the CP210x VCP Driver Installer” option in that window if you are ready to install the driver. You do not

need to have the motherboard's USB connector plugged into the PC's USB port for this step.

3. If selected, the driver installer will now launch, providing an option to specify the driver installation location. After

pressing the “Install” button, the installer will search your system for copies of previously installed CP210x

Virtual COM Port drivers. It will let you know when your system is up-to-date. The driver files included in this

installation have been certified by Microsoft.

4. If the “Launch the CP210x VCP Driver Installer” option was not selected in Step 3, the installer can be found in

the location specified in Step 2 (by default, C:\SiLabs\MCU\CP210x\Windows). At this location, run

CP210xVCPInstaller.exe.

5. To complete the installation process, connect the included USB cable between the host computer and the

COMM USB connector (P4) on the C8051T62x Motherboard. Windows will automatically finish the driver

installation. Information windows will pop up from the taskbar to show the installation progress.

6. If needed, the driver files can be uninstalled by selecting the “Silicon Laboratories CP210x USB to UART Bridge

(Driver Removal)” option in the “Add or Remove Programs” window.

5.3. Configuration Wizard 2

Configuration Wizard 2 is a code generation tool for all Silicon Laboratories devices. Code is generated through the

use of dialog boxes for each device peripheral as shown in Figure 2.

Figure 2. Configuration Wizard 2 Utility

The Configuration Wizard utility helps accelerate development by automatically generating initialization source

code to configure and enable the on-chip resources needed by most design projects. In just a few steps, the wizard

creates complete startup code for a specific Silicon Laboratories MCU. The program is configurable to provide the

output in C or assembly language.

For more information, refer to the Configuration Wizard 2 help available under the Help menu in Configuration

Wizard 2 or refer to the Configuration Wizard 2 documentation. Documentation and software are available from the

downloads webpage: www.silabs.com/mcudownloads.

5.4. Keil uVision2, uVision3, and uVision4 Silicon Laboratories Drivers

As an alternative to the Silicon Laboratories IDE, the µVision debug driver allows the Keil µVision2, µVision3, and

µVision4 IDEs to communicate with Silicon Laboratories’ on-chip debug logic. In-system Flash memory

programming integrated into the driver allows for rapid updating of target code. The µVision2, µVision3, and

µVision4 IDEs can be used to start and stop program execution, set breakpoints, check variables, inspect and

modify memory contents, and single-step through programs running on the actual target hardware.

For more information, refer to the µVision driver documentation. The documentation and software are available

from the downloads webpage: www.silabs.com/mcudownloads.

5.5. Programming Utilities

The Silicon Labs IDE is the primary tool for downloading firmware to the MCU during development. There are two

software programming tools that are intended for use during prototyping or in the field: the MCU Production

Programmer and the Flash Programming Utilities. The MCU Production Programmer is installed with the IDE to the

directory, C:\Silabs\MCU\Utilities\Production Programmer\ (default). The Flash Programming Utilities can be

optionally installed from the web installer, and are installed to C:\Silabs\MCU\Utilities\FLASH Programming\

(default).

5.6. ToolStick Terminal

The onboard debug circuitry provides both an in-system programming and debugging interface and a

communications interface to the target microcontroller's UART. The ToolStick Terminal software can access the

debug hardware's communications path and provides a terminal-like interface on the PC. Note that for concurrent

debugging and UART communications, the CP2103 USB-to-UART bridge is also included onboard.

In addition to the standard terminal functions (Send File, Receive File, Change Baud Rate), two GPIO pins on the

target microcontroller can be controlled using the terminal for either RTS/CTS handshaking or software-

configurable purposes. The ToolStick Terminal software is available on the downloads webpage: www.silabs.com/

mcudownloads.
