Cypress Semiconductor has 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 design flexibility, along with CapSense, Cypress’s capacitive sensing technology, to cost-sensitive and high-volume applications.
PSoC 4000 devices offer a scalable architecture that enables seamless migration to larger PSoC 4 families.
The PSoC 4000 family also integrates programmable digital and analogue peripherals, for functions such as Timers, Counters, Pulse Width Modulators (PWMs), I2C and Comparators, to suit a variety of consumer and industrial applications and 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 ARM-Cortex-M0 system-on-chip with the right mix of performance, power and peripherals,” said John Weil, Senior Director of PSoC Marketing and Applications for Cypress’s Programmable Systems Division. “We believe that there is no simpler way to design your next-generation product than 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 sensing in noisy environments using Cypress’s patented CapSense Sigma-Delta (CSD) sensing method, ensuring 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 analogue and digital glue logic to facilitate high-performance custom signal chains.
