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

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. 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 MCUs. The PSoC 4000 family delivers PSoC’s hallmark design flexibility, along with CapSense, Cypress’sindustry-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 also 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.
