Cypress Semiconductor Corp. has unleashed the PSoC 4 programmable system-on-chip (PSoC) architecture that combines the firm's PSoC analogue and digital fabric and CapSense capacitive touch technology with ARM's Cortex-M0 core. According to the company, the scalable, cost-efficient architecture delivers PSoC's trademark flexibility, analogue performance and integration, along with access to dozens of free PSoC components!"virtual chips" represented by icons in Cypress's PSoC Creator integrated design environment (IDE).

The PSoC 4 device class will challenge proprietary 8bit and 16bit MCUs, along with other 32bit devices. The PSoC 4 architecture enhances Cypress's patented CapSense capacitive-touch sensing technology by offering significant leadership in noise immunity, flaunted the firm. In addition to capacitive sensing, PSoC 4 targets field-oriented control (FOC) motor control, temperature sensing, security access, portable medical and many other applications.

The PSoC 4 architecture claims to offer best-in-class power leakage of 150nA while retaining SRAM memory, programmable logic and the ability to wake up from an interrupt. In stop mode, it consumes only 20nA while maintaining wake-up capability. It boasts the widest operating voltage range of any Cortex-M0-based device, enabling full analogue and digital operation from 1.71-5.5V. The architecture facilitates integrated, high-performance custom signal chains and provides both configurable analogue and flexible routing, added Cypress.

PSoC 4 leverages the PSoC Creator IDE with easy-to-use graphical interface that enables designers to drag and drop pre-characterized, production-ready analogue and digital IP blocks!PSoC Components!into a single PSoC device to create customised, feature-rich and highly differentiated end products. Cypress's platform solution!PSoC 4, PSoC Creator and PSoC Components!simplifies and accelerates the design process, reduces bills of material and provides extraordinary system value, the company indicated.

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 MCU, 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.鐃All PSoC devices are dynamically reconfigurable, enabling designers to transform resources on-the-fly and to execute tasks with fewer ICs.

Cypress plans to announce the availability of the PSoC 4 families in 1H13.
