Cypress’s New PSoC® Creator™ 2.2 IDE Delivers New Components, Easy Component Distribution and Custom Documentation

Along with a New Component Pack Release, Version 2.2 Simplifies Design and Enhances Collaboration for Global Design Teams

SAN JOSE, Calif.–(BUSINESS WIRE)– Cypress Semiconductor Corp. (NAS: CY) today introduced PSoC® Creator™ 2.2, the integrated design environment (IDE) for Cypress’s PSoC 3 and PSoC 5LP architectures, along with a new Component Pack. The new software update simplifies and accelerates designs with new PSoC Components™, enabling easy creation and distribution of custom Components, and generates custom datasheets.

PSoC Creator is more than merely an IDE. In addition to a robust compiler and programmer, it allows users to configure PSoC programmable hardware into a custom one-chip solution. It includes a rich library of over 100 pre-verified, production-ready analog and digital Components—”virtual chips,” represented by an icon—that users can drag-and-drop into a design and configure to suit a broad array of application requirements. Developers can download the new software free of charge at www.cypress.com/Creator.

PSoC Creator 2.2 with Component Pack 5 features seven new and five enhanced Components including MDIO Interface, SAR Sequencer and a digital Component pack with multiple Flip/Flops, a Pulse Converter and a Frequency Divider. It also offers a new PWM-based sensor interface Component that connects to Analog Devices’ TMP05 temperature sensors. Components integrate system interfaces and discrete ICs into a PSoC solution, reducing BOM costs and board-space.

“What truly sets PSoC apart from other solutions is not just the flexible architecture of the chips, but the ability to simultaneously design both hardware and software in the PSoC Creator IDE,” said John Weil, Senior Director of PSoC Marketing and Applications for Cypress. “PSoC Components can encapsulate hardware layout, peripheral initialization and the required application firmware to generate a complete virtual IC. This allows engineers to create unique designs that can be optimized for almost any application and then shared and reused throughout their organization.”

Version 2.2 adds easy import and export tools to simplify the sharing of user-created PSoC Creator Components. Customers can generate complete Components and easily pass them to a system integration team. This allows global engineering teams to work on the hardware and software of a particular block, complete and package their design and send to a system integration team. PSoC Creator customers can easily implement Center of Excellence design methodologies throughout their global design teams.

Simplifying project creation, PSoC Creator 2.2 generates complete, custom datasheets for any PSoC project design. Generated datasheets contain system settings, clock and pin details, registers, and Component set-up for each …read more

Microchip Expands PIC24 Lite Microcontroller Portfolio with Advanced Analog Integration and 5V Operation

New PIC24 Lite MCUs Feature On-Chip Op Amps, 8-bit DACs, 12-bit ADC, Flexible PWM Modules and eXtreme Low Power Technology for Cost-Sensitive Automotive, Consumer, Medical and Industrial Applications

CHANDLER, Ariz.–(BUSINESS WIRE)– Microchip Technology Inc. (NAS: MCHP) , a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced a new addition to its 16-bit PIC® microcontroller (MCU) portfolio with the low cost PIC24F “KM” family. This family offers up to 16 KB Flash, 2 KB RAM and 512B EEPROM, along with advanced analog integration, in low pin-count options for cost-sensitive automotive, consumer, medical and industrial applications.

Watch a short video: http://www.microchip.com/get/99E7

The PIC24F “KM” family provides a new level of integrated analog functionality such as a 12-bit ADC with threshold detection, 8-bit DACs for analog control loops and precision comparator references, and op amps to assist in sensor amplifications. The PIC24 “KM” MCUs are the first to feature the new Multiple-output Capture Compare PWM Module (MCCP) and Single-output Capture Compare PWM Module (SCCP) peripherals, which include integrated timers and advanced PWM control to enable motor-control, power-supply and lighting applications. The MCCP and SCCP modules combine timers, input captures, output compare and PWM functions in a single time base for optimal flexibility. These modules include 16/32-bit timer support, and can operate from a high-speed clock for higher resolution due to their ability to operate asynchronously. They also allow for automatic operations during sleep mode, to optimize power consumption.

This is also the first PIC24 family to offer a Configurable Logic Cell (CLC) for increased on-chip interconnection of peripherals. The CLC module helps in creating custom real-time logic functions on-chip and is supported by the CLC configuration tool, which helps in coding the circuit graphically instead of in assembly or C, thereby saving time for the programmers.

In addition to advanced peripheral integration, the “KM” family includes support for both 3V and 5V applications. Many customers prefer 3V operation for portable, battery-operated applications, and the 3V “KM” products all include eXtreme Low Power (XLP) for optimal battery life. Other customers prefer 5V operation with the PIC24FV16KM product variants, for applications where more dynamic range, noise immunity and robustness are the key factors. The PIC24F “KM” with its extreme low power and advanced analog integration, is an excellent solution for customers working on cost-sensitive applications, such as flow meters, smoke detectors, stepper and BLDC motors, LED dimming, battery charging, environmental …read more

NORWOOD, Mass.–(BUSINESS WIRE)– Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications, today introduced the ADP1051 advanced digital power controller with PMBus™ interface targeting ultra-compact, high density isolated DC-to-DC power supply systems with parallel/redundant capability. The ADP1051 is an extremely versatile digital controller with six PWM (pulse width modulation) logic outputs that can be programmed using an easy-to use graphic user interface (GUI) via the PMBus interface. The device enables high energy efficiency topologies including full bridge and active clamp forward variants with precision drive timing and control of secondary synchronous rectifiers. Energy efficiency is further optimised using adaptive dead-time compensation to improve the efficiency over the load range and programmable light load mode operation combined with low device power consumption (<100mW) to reduce system low power standby losses. The ADP1051 implements an extensive PMBus command set including the ability to accurately read input and output power measurements and enable the end-user to make intelligent system management decisions to optimize energy efficiency. The tiny size 4 x 4 mm LFCSP package makes the ADP1051 ideal for high density, ultra-compact isolated DC-to-DC power module or embedded designs for networking, communications and industrial applications ranging typically from 100 W upwards.

The ADP1051 power controller is easily programmed using an intuitive graphical-user interface which enables customers to design and store settings in the high reliability, internal EEPROM memory. The ADP1051 implements several features to enable a robust system of parallel and redundant operation for customers that require high availability for increased current scaling. The device includes master/slave synchronization, reverse current protection and pre-bias start-up, accurate passive or droop current sharing between power supplies and a patented technique to identify and safely shutdown an erroneous power supply in parallel operation mode.
