Cypress Semiconductor Corp. has introduced version 2.1 of its PSoC Express, a free development tool for Programmable SoC (PSoC) mixed-signal arrays that helps simplify embedded design.

The product includes capabilities that allow software developers to write modules for specific functions. It also adds many device drivers that designers can select from to easily implement functions within a PSoC device, including seven-segment displays, thermocouples, accelerometers, I?C remote monitor and control devices, distance sensors and ambient light sensors.

PSoC devices employ a highly configurable SoC architecture for embedded control design, offering a flash-based equivalent of a field-programmable ASIC without lead-time or NRE penalties. PSoC devices integrate configurable analog and digital circuits, controlled by an on-chip MCU, providing both enhanced design revision capability and component count savings.

Cost savings
"A single PSoC device can integrate as many as 100 peripheral functions, saving customers design time, board space and power consumption while improving system quality. Customers can save from 5 cents to as much as $10 in system costs," explained Nick Gan, Cypress' area sales manager for Southeast Asia.

PSoC Express 2.1 also adds a level of integration with the company's full-featured PSoC Designer software, allowing users to complete designs exclusively at a high-level (using only PSoC Express), combine high-level and low-level design (start with PSoC Express and complete with PSoC Designer), or develop exclusively at the machine-level (using only PSoC Designer). Other new features include user definable pins and memory map, a state machine creator, multi-object move capability and the ability to duplicate and rename circuits.

With PSoC Express, designers work within their areas of application expertise, defining a custom solution by choosing input and output devices from a catalog, and then logically linking them to define system behavior. For example, a user can select temperature sensors, voltage inputs, fans, LEDs and then define temperature regions for fan operation, voltage monitor thresholds and "sequence-on" logic.

Faster custom apps
Within PSoC Express, the designer is able to verify designs through simulation, then generate and download the device-programming file. The tool allows users to target the design to any of Cypress's PSoC devices. It also creates customized project documentation including a datasheet with register map, interface schematics and BOM. Without writing any MCU code, designers implement reliable, custom applications faster than they can write the requirements.
