Cypress adds entry-level chips to mixed-signal programmables
These 32-bit ARM-based systems-on-chip are intended for quick, simple upgrades of legacy 8-bit and 16-bit MCUs. The PSoC 4000 family delivers PSoC’s design flexibility, along with the CapSense capacitive sensing technology, to cost-sensitive and high-volume applications. PSoC 4000 devices have 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. The devices are available in 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 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 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 suitable 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.
PSoC solutions bring the flash-based equivalent of a field-programmable ASIC to embedded designs without lead-time or NRE penalties. PSoC integrates configurable analogue 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.
Pricing begins from $0.29 (1000).
