Right-click on the group name and choose Add file to group. In dual-cell battery mode, this pin must be connected directly to ground. This supply voltage is not required in low power sleep mode. Can be used as a bias or for generating a custom reference voltage ports UART operation; 20 MHz low power oscillator requires very little bias datahseet External oscillator: BT2 is only used in two-cell mode. After receiving the interrupt signal, the microcontroller then turns on two external FETs thereby energizing both the audio alarm and the two LED flood lights.

In addition, power supply and ground pins are included. If you decide to use this accelerometer in a new design—sans the development and evaluation boards—you’ll want to use the LIS2DH accelerometer device itself on your new PCB design.


Refer to the CF93x- CF92x data sheet for more information on the use of external dahasheet.

Select Add Groups to project. The CF Development Kit is intended as a development platform for the microcontrollers in the. The audio piezo alarm chosen for this project is a slow warble alarm with a resonant frequency range of to Hz. Register 0x32 sets the acceleration threshold set to mg for when the Int1 signal is driven; the mg threshold setting is what makes the motion detector so sensitive to slight accelerations.

This pin is the external clock input in capacitor or RC oscillator configurations. The code excerpt below shows the necessary code changes. The capacitors are connected to P0. Factory Defaults 14 P Prev Next CF D. Figure 7 below depicts the connections between the various components. CFTB datasheet and specification datasheet. Figure 9 on page 14 shows the factory default shorting block positions In single-cell battery mode, this pin must be connected to VBAT through a 0.

Below are some suggestions for reducing the active supply current: Wafer Storage Guidelines It is necessary to conform to appropriate wafer storage practices to avoid product degradation or contamination.

J2[8] and H1[2] connectors. During the development of this project I got hung up on the Clock Phase and Clock Pulse configurations.

Target Board The CF Development Kit includes a target board with a CF device pre-installed for evaluation and preliminary software development. The operation of these switches require appropriate firmware running on the CF MCU that can sense the state of the switch. Information windows will pop up from the taskbar to show the installation dataxheet. A In AD1 P1. August 31, by Nick Davis This project uses a C microcontroller development kit, an c8051f93 evaluation board, and Simplicity Studio IDE—all from Silicon Labs—to rather quickly and easily build a motion-detecting alarm system.

Initial response time for FA requests that meet this requirements will be three weeks. To create a new profile:
