The PSoC 4 architecture combines Cypress Semiconductor’s PSoC (programmable system-on-chip) analog and digital fabric and CapSense capacitive touch technology with ARM’s power efficient Cortex-M0 core. The scalable, cost-efficient architecture delivers PSoC’s trademark flexibility, analog 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 new PSoC 4 device class is designed to challenge proprietary 8-bit and 16-bit microcontrollers (MCUs), along with other 32-bit devices. The architecture was chosen by Semiconductor Industry News for its 19th annual semiconductor of the year award.
Cypress recently announced the first two product families from its PSoC 4 architecture: the PSoC 4100 and PSoC 4200 families. The 4100 family, the lowest-cost ARM-based PSoC, brings PSoC flexibility and integration to cost-sensitive, high-volume applications.
The 4200 family features faster processor and ADC sampling speeds and PLD-based enhanced universal digital blocks (UDBs). In addition to capacitive sensing applications, PSoC 4 targets field-oriented control (FOC) of motors, temperature sensing, security access, portable medical and many others.
The PSoC 4 architecture offers power leakage of just 150 nA while retaining SRAM memory, programmable logic and the ability to wake up from an interrupt. In stop mode, it consumes only 20 nA while maintaining wake-up capability.
It has a wide operating voltage range for a Cortex-M0-based device, enabling full analog and digital operation from 1,71 V to 5,5 V. The architecture facilitates integrated, high-performance custom signal chains and provides both configurable analog and flexible routing.
