Cypress empowers developers with sensing solutions for industrial designs incorporating metals

Cypress Semiconductor has unveiled the PSoC 4700 series of microcontrollers (MCUs) that uses inductive sensing to detect touch inputs for products using metal surfaces.

Consumer, industrial, and automotive products are using metallic materials to differentiate with their customers through improved aesthetics.

According to Cypress: “The new series frees developers to incorporate these metals by making inductive sensing as easy to use as Cypress’ CapSense solutions for capacitive-sensing.”

The device is designed to “empower” developers to solve their capacitive and inductive sensing problems and is suitable for “state-of-the-art” industrial design.

The PSoC 4700 inductive sensing solution is supported in Cypress’ PSoC Creator Integrated Design Environment (IDE), which allows users to drag and drop production-ready hardware blocks, including the new inductive sensing capability, into a design and easily configure them via a simple graphical user interface.

The PSoC 4700 MCUs are based on a 32-bit Arm Cortex-M0+ core and integrate programmable analog and digital blocks. The devices can support up to 16 sensors to implement digital functions or custom algorithms for interfaces in various form-factors, including buttons, linear and rotary encoders, proximity sensing or free-form. Cypress claims its PSoC 4700 inductive-sensing solution provides “superior noise immunity” for reliable operation, even in “extreme environmental conditions”.

Cypress’ free PSoC Creator IDE aims to simplify system design by enabling concurrent hardware and firmware development using PSoC Components—embedded ICs represented by an icon in the IDE.

Engineers can configure the programmable analog and digital blocks in PSoC by dragging and dropping components on the PSoC Creator schematic and customising them with graphical component configuration tools. The tool features auto-calibration that automatically compensates for manufacturing variations.
