Cypress Expands the PSoC 4 Architecture with Entry-Level PSoC 4000 Devices

Last Updated: April 29, 2014

Family Offers Low-Cost ARM® Cortex™-M0 Devices
Integrated with CapSense®, the Industry’s Best Capacitive Sensing Solution

SAN JOSE, Calif., April 29, 2014 – Cypress Semiconductor Corp. (NASDAQ: CY) today introduced a new product family from its PSoC® 4 architecture that offers a low-cost, entry-level 32-bit ARM®-based system-on-chip for quick, simple upgrades of legacy 8-bit and 16-bit microcontrollers (MCUs). The PSoC 4000 family delivers PSoC’s hallmark design flexibility, along with CapSense®, Cypress’s industry-leading capacitive sensing technology, to cost-sensitive and high-volume applications. PSoC 4000 devices have a truly scalable architecture that enables seamless migration to larger PSoC 4 families.

The PSoC 4000 family integrates programmable digital and analog peripherals, for functions such as Timers, Counters, Pulse Width Modulators (PWMs), I2C and Comparators, to suit a variety of consumer and industrial applications. The devices are available in extremely small-footprint package options down to 3 x 3 x 0.6 mm. The scalable, cost-efficient architecture is complemented by the free, downloadable PSoC Creator™ Integrated Design Environment (IDE), which simplifies system design and accelerates time-to-market by allowing hardware and firmware co-design.  

“The PSoC 4000 family is the world’s lowest cost ARM-Cortex-M0 system-on-chip with the right mix of performance, power and peripherals to make migration to 32-bit a no-brainer,” said John Weil, Senior Director of PSoC Marketing and Applications for Cypress’s Programmable Systems Division. “There is no simpler way to design your next-generation product with this robust core and the added value of a sophisticated capacitive sensing solution.”

The PSoC 4000 devices enable touch user interface designs with up to 16 CapSense I/Os that can be used to implement buttons, sliders and proximity sensors. CapSense delivers robust sensing in noisy environments using Cypress's patented CapSense Sigma-Delta (CSD) sensing method, ensuring superior immunity to conducted and radiated noise with a signal-to-noise ratio of greater than 100:1. Operating from 1.71V to 5.5V, the PSoC devices are ideal for a wide range of regulated and unregulated battery applications, including single coin cell battery operation.

Cypress also offers larger families in the PSoC 4 architecture that integrate discrete analog and digital glue logic to facilitate high-performance custom signal chains.

The PSoC 4000 family is currently sampling with production expected in May 2014. Parts will be available in 8-pin SOIC, 16-pin QFN, 16-pin SOIC or 24-pin QFN packages from Cypress and its authorized distributors, with some parts available for only $0.29 each at quantities of 1,000 units.

MCUs Can’t. PSoC Can.
PSoC solutions bring the flash-based equivalent of a field-programmable ASIC to embedded designs without lead-time or NRE penalties. PSoC integrates configurable analog and digital circuits with an on-chip microcontroller, reducing component count and simplifying revisions. A single PSoC device can integrate as many as 100 peripheral functions, accelerating cycle time and improving quality while reducing board space, power consumption, and system cost.

PSoC “future-proofs” designs, protecting them against last-minute specifications changes. It enables firmware-based changes at any point in the design cycle—even out in the field. All PSoC devices are dynamically reconfigurable, enabling designers to transform resources on-the-fly and to execute tasks with fewer ICs.

About CapSense
Cypress has shipped more than one billion CapSense touch-sensing controllers, which have replaced over five billion mechanical buttons in mobile handsets, laptops, consumer electronics, white goods, automotive applications, and virtually any system that has a mechanical button or switch, making Cypress the industry touch-sensing leader. The CapSense portfolio, the industry's broadest and most integrated, enhances industrial design and reliability with the most noise-immune and water tolerant capacitive touch-sensing interfaces, including proximity sensing where direct touch is not required. CapSense proximity sensing can provide power savings by activating an interface only when needed while further enhancing industrial designs by only exposing interfaces when necessary.
