CapSense And CapSense Plus Product Brief

  1. 1. ADVANTAGES Up to 46 Capacitive/General-purpose I/O • LED Driver/Backlight Control • Motor Control •Power Management • I/O Expansion • Gyro • Accelerometer • Ambient Light-sensing 2.4V–5.25V Supply Voltage 512B–1KB RAM 8KB–16KB Flash In-system Serial Programming (ISSP) Free Development Software (PSoC Designer™ ) Full-featured In-circuit Emulator and Programmer I2 C, SPI, UART and USB Communication Interfaces Industry’s Smallest Packages (e.g. 16-pin 3x3x0.6mm QFN) Capacitive sensing made easy — POWERED BY PSoC® MIXED-SIGNAL ARRAY TeCHNOLOGY Capacitive sensing is fast becoming the solution of choice for front-panel display and media control applications. Best-in-class durability, decreased bill of materials (BOM), and a clean appearance make this elegant interface attractive to a wide range of designs. Cypress’s CapSense solution offers system designers numerous advantages over traditional capacitive sensing products by being a self-contained system— increasing flexibility, reducing board space, and lowering cost. MCU CapSense CIRCUIT ANALOG/DIGITAL GPIO COMMUNICATION CapSenseINPUTS ADDITIONAL FUNCTIONS HOST + – Because of the unique PSoC® architecture, designers can easily integrate multiple functions (e.g. LED drivers and backlighting), in addition to capacitive sensing. The PSoC CapSense solution also delivers benefits such as easy communications using either I2 C, SPI, UART, or USB interfaces, the ability to implement buttons, sliders, touchpads, touchscreens, and proximity sensors with the same device, and the ability to make quick design changes using the flash-based PSoC architecture.
