4. CapSense Product Portfolio
Cypress‘s CapSense controller solutions are based on our Programmable System-on-Chip (PSoC
®
) platform and
offer a wide range of features.
4.1 Cypress’s CapSense Controller Solutions
Cypress is the world leader in capacitive sensing technologies and their broad range of solutions provides robust
noise immunity, enable quick time to market, and system scalability. With CapSense controllers, you can:
Replace mechanical components with simple CapSense buttons and sliders.
Reduce total BOM cost and form factor by integrating CapSense with other system components.
Optimize board space with our small form factor packaging (WLCSP, SOIC, and QFN).
Use our advanced sensing techniques for easy finger detection through 15 mm of glass or 5 mm of plastic.
Get to market more quickly using SmartSense Auto-Tuning.
Implement additional user interface functionality, such as LED effects, proximity and water rejection.
Cypress offers a wide range of configurable and programmable CapSense controllers. Configurable CapSense
controllers are hardware or I
2
C configurable. Programmable devices provide complete flexibility to meet your exact
design requirements, including reducing BOM cost by integrating further system functionality. The different CapSense
device families are listed in the following sections.
4.1.1 CapSense Express Controllers (Configurable Solutions)
4.1.1.1 CY8CMBR20xx
The CY8CMBR20xx device features a wide operating voltage range, 1.71-V to 5.5-V operating voltage and CSD
capacitive sensing with SmartSense Auto-Tuning. These devices are hardware configurable; no I
2
C is required.
4.1.1.2 CY8C201xx
CY8C201xx devices feature configurable I/Os that can be used as capacitive sensing inputs or as GPIOs for driving
LEDs, interrupt outputs, wake-up on interrupt inputs and other digital I/O functionalities. These devices support
register-based configuration through an I
2
C interface.
4.1.2 CapSense Controllers (Programmable Solutions)
4.1.2.1 CY8C20x34, CapSense
CY8C20x34 devices feature CSA_EMC capacitive sensing and can implement up to 25 CapSense buttons.
4.1.2.2 CY8C20x36A, CapSense
CY8C20xx36A devices can operate at voltages as low as 1.71 V to 5 V; offer both CSA_EMC and CSD capacitive
sensing, SmartSense, and support up to 33 CapSense buttons.
