Software Overview The following software is necessary to build a project, download code to, and communicate with the target microcontroller. 8051 Evaluation Toolset Silicon Labs Integrated Development Environment (IDE) Other useful software that is provided on the development kit CD and the Silicon Labs Downloads (www.silabs.com/mcudownloads) website includes:...
- Page 5 C8051F996-DK 7. Download the project to the target by clicking the Download Code button in the toolbar. Note: To enable automatic downloading if the program build is successful select Enable automatic con- nect/download after build in the Project Target Build Configuration dialog. If errors occur during the build process, the IDE will not attempt the download.
- Page 6 C8051F996-DK 5.3. Configuration Wizard 2 The Configuration Wizard 2 is a code generation tool for all of the Silicon Labs devices. Code is generated through the use of dialog boxes for each of the device's peripherals. Figure 3. Configuration Wizard 2 Utility The Configuration Wizard 2 utility helps accelerate development by automatically generating initialization source code to configure and enable the on-chip resources needed by most design projects.
- Page 7 C8051F996-DK 5.4. Silicon Labs Battery Life Estimator The Battery Life Estimator is a system design tool for battery operated devices. It allows the user to select the type of battery they are using in the system and enter the supply current profile of their application. Using this information, it performs a simulation and provides an estimated system operating time.
- Page 8 C8051F996-DK Figure 5. Battery Life Estimator Discharge Profile Editor The Discharge Profile Editor allows the user to modify the profile name and description. The four text entry boxes on the left hand side of the form allow the user to specify the amount of time the system spends in each power mode.
- Page 9 C8051F996-DK The wakeup frequency box calculates the period of a single iteration through the four power modes and displays the system wake up frequency. This is typically the "sample rate" in low power analog sensors. Once the battery type and discharge profile is specified, the user can click the "Simulate" button to start a new simulation.

Keil µVision2 and µVision3 Silicon Labs Drivers As an alternative to the Silicon Labs IDE, the µVision debug driver allows the Keil µVision IDE to communicate with Silicon Labs on-chip debug logic. In-system Flash memory programming integrated into the driver allows for rapidly updating target code.
- Page 11 C8051F996-DK 7. Target Board The C8051F996 Development Kit includes a target board with a C8051F996 device pre-installed for evaluation and preliminary software development. Numerous input/output (I/O) connections are provided to facilitate prototyping using the target board. Refer to Figure 7 for the locations of the various I/O connectors.

Internal Oscillators The C8051F996 device installed on the target board features a factory calibrated programmable high-frequency internal oscillator (24.5 MHz base frequency, ±2%) and a low power internal oscillator (20 MHz ±10%). After each reset, the low power oscillator divided by 8 results in a default system clock frequency of 2.5 MHz (±10%).
- Page 16 C8051F996-DK 7.5. Switches and LEDs (J1, J5, J8, J15, J16, SW1, SW2, SW3) Three push-button switches are provided on the target board. Switch SW1 (RESET) is connected to the reset pin of the C8051F996. Pressing SW1 puts the device into its hardware-reset state. Switches SW2 (P0.2) and SW3 (P0.3) are connected to the C8051F996’s general purpose I/O (GPIO) pins through headers.
