The EVM is a breakable PCB which consists of 3 sections. The first section is a USB to I2C converter based on MSP430F5528 micro-controller, the second section contains the FDC1004Q and the third section is a touchless sensor (to demonstrate the sensitivity of the FDC1004Q) . The third section can be removed and replace with customized sensors to evaluate the capabilities of the FDC1004Q in various applications. The FDC1004QEVM can be used with the FDC1004EVM GUI. The software is able to configure the FDC1004Q’s registers, display on four graphs (one for each measurement) the capacitive values and export data in CSV format. The EVM contains one FDC1004Q (See Table 1). Table 1. Ordering 2 DEVICE IC Package U1 FDC1004QDGS VSSOP 10pin Setup This section provides a general description about FDC1004QEVM, its I/O connectors and how to properly setup the evaluation module. 2.1 FDC1004QEVM The FDC1004QEVM is divided in three sections: 1. USB to I2C section: this has the purpose to interface the communication of FDC1004Q to a USB port. 2. FDC1004Q section: this section embeds FDC1004Q capacitive to digital converter. 3. Sensor section: this section contains a capacitive sensor that can be used for human proximity. The EVM has precut lines on the borders of each section that allow for a flexible and specific system design. As an example of the flexibility of this design, the sensor can be replaced with a customer sensor, or the MCU section can be separated to allow for a remote placement of the FDC1004Q. 4 FDC1004QEVM User's Guide SNAU178 – April 2015 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Setup www.ti.com USB to I2C FDC1004 SENSOR Figure 1.

The I2C communication with FDC1004Q is fully managed by the MSP430F5528IRGC microcontroller (U3). The FDC1004Q has a fixed I2C address. 2.4 SW Setup Ensure that the FDC1004QEVM GUI and the drivers have been installed on the host computer. Plug the EVM into an available USB port on the host. 2.5 Operation Plug the EVM into the host computer. The host computer should automatically detect the device as an EVM. Launch the GUI and configure the desired data acquisition mode for FDC1004Q. Then, it should automatically start measuring on the configured sensors. 3 Board Layout Figure 2 and Figure 3 show the board layout of the FDC1004QEVM. Sensor layout has been designed to demonstrate human proximity sensing with a single sensor. A shield layer below the sensor and a shield ring around the sensor is designed to significantly reduce parasitic capacitance interference from directions not intended to sense the target. The intended sensing area for this EVM is towards the top side of the sensor. For more information about shielding, refer to the application note Capacitive Sensing: The Ins and Outs of Active Shielding (SNOA926). Figure 2.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
