Cypress’s PSoC ® 4 Architecture Delivers the Industry’s Most-Flexible, Lowest-Power ARM ® Cortex™-M0-Based Devices for Embedded Designs

Truly Scalable, Infinitely Reconfigurable Architecture with Component-Based Design Methodology is Positioned to Challenge 8-, 16-, and 32-bit Standalone MCUs

SAN JOSE, Calif.–(BUSINESS WIRE)– Cypress Semiconductor Corp. (NAS: CY) today unveiled the PSoC® 4 programmable system-on-chip architecture, which combines Cypress’s best-in-class PSoC analog and digital fabric and industry-leading CapSense® capacitive touch technology with ARM®‘s power-efficient Cortex™-M0 core. The truly 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. The new PSoC 4 device class will challenge proprietary 8-bit and 16-bit microcontrollers (MCUs), along with other 32-bit devices. Cypress plans to announce the availability of new PSoC 4 families in the first half of 2013.

The PSoC 4 architecture enhances Cypress’s patented, industry-leading CapSense capacitive-touch sensing technology by offering significant leadership in noise immunity. In addition to capacitive sensing, PSoC 4 targets field-oriented control (FOC) motor control, temperature sensing, security access, portable medical, and many other applications.

“PSoC 4 enables design engineers to leverage the overall trend toward industry-standard, lower-cost ARM-based solutions, the broad availability of ARM software, and the migration of 8-and 16-bit MCU applications to 32-bit solutions,” said John Weil, Senior Director of PSoC Marketing for Cypress’s Programmable Systems Division. “It is the industry’s only fully scalable, infinitely reconfigurable Cortex-M-class MCU with best-in-class analog integration. It can replace entire portfolios of proprietary MCUs and analog solutions, and it is well-positioned to capture significant market share.”

“Inserting the popular Cortex-M0 processor core into the highly-customizable logic and analog circuitry of Cypress’s PSoC products makes a very appealing combination for applications with unique I/O requirements that warrant a higher performance processor or the widely-used ARM architecture,” said Tom Starnes, Principal Analyst with semiconductor market research firm Objective Analysis. “The trim PSoC 4 with the highly optimized Cortex-M0 processor makes it easier to step up from 8- and 16-bit or proprietary MCU architectures.”

The PSoC 4 architecture offers best-in-class power leakage of 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 the widest operating voltage range of any Cortex-M0-based device, enabling full analog and digital operation from 1.71V to 5.5V. The architecture …read more

Fairchild Semiconductor’s BLDC/PMSM Motor Controller with Parallel Processing Cores Provides Simple Conversion of AC Motor Control Designs

Development Tool and Configurable Motor Control Libraries Minimize Design Resources for Faster Time-to-Market

SAN JOSE, Calif.–(BUSINESS WIRE)– Motor control application designers are now moving away from the traditional universal or AC motor design to a more sophisticated brushless DC (BLDC) motor or permanent magnet synchronous motor (PMSM) design. However, choosing either of these methods can be challenging if the designer has limited access to advanced, complex motor control algorithms. This can lead to significant spending of research and development resources and longer design times.

To help designers with these cost and software burdens, Fairchild Semiconductor (NYS: FCS) developed the FCM8531 analog and digital integrated motor controller. The FCM8531 is a tailored configurable solution complete with user guides, reference designs, and evaluation boards that help motor control designers shorten time-to-market and minimize software design efforts.

Parallel Processors in a One-Chip Design

The FCM8531 is a 3-phase, hybrid BLDC/PMSM controller with two parallel processors – an advanced motor controller (AMC) and an embedded microcontroller (MCU) – that provides a complete, one-chip solution for complex motor control applications. The two core processors work independently but collaboratively to exchange data through an internal communications interface that helps to avoid system hang-ups and improves hardware protection. The FCM8531 minimizes the software burden with its integrated hardware controller and MCU interface management and achieves a fast load-response motor system with increased efficiency.

Tailored Design for Simplified Functionality

Capable of adapting to various motor designs, the AMC performs powerful algorithms such as sine wave control, field oriented control (FOC) and direct and quadrature (DQ) control, using Fairchild’s libraries that can be configured and stored to provide high performance motor control. The MCU interface, paired with the AMC, enables users to easily change the register values for different motor operation flows and characteristics. The device is ideally suited to solve start-up jerks in sensor-less fan applications, as well as acoustic noise and low efficiency issues in various fan and …read more
