Cypress MicroSystems Announces Low-Power, Programmable Mixed-Signal Array for Portable Control Applications
Programmable System-on-ChipTM (PSoC) Devices Combine Speed, Flexibility, Low Cost with the Industry's Lowest-Power, System-Aware Sleep Mode for a Wide Range of Portable, Flash-Based Applications
PSoC devices are high-performance, field-programmable, mixed-signal arrays for high-volume embedded-control functions in consumer, industrial, office automation, telecom and automotive applications. With a typical sleep current of just 3 ìA—with all power supervisory functions turned on—PSoC offers the lowest system power consumption in the industry for flash-based applications, enabling true portability and maximum flexibility at a very competitive price. “Most manufacturers of embedded microcontrollers specify ‘sleep mode’ with all functions turned off,” said PSoC’s sleep-mode specification includes operation of all power supervisory functions, including power-on reset (POR), which ensures that the part only starts to operate when power is within operating limits; brown-out detection (BOD), which insures that the part shuts down safely when power is not within preset limits; low-voltage detection (LVD), which alerts the processor that power is failing; sleep timer, which wakes the part periodically to perform time-critical functions; and watchdog timer (WDT), which resets the processor if it is not properly executing code. All of these functions are required in flash-based embedded designs in order to avoid corrupting code or data stored in the flash memory in the event of a power failure. PSoC CY8C26x family devices draw just 3 ìA in sleep mode with all power supervisory functions turned on, for a total power consumption of 10 ìW. In contrast, one industry-leading controller claims a sleep current of only 0.1 ìA; however, with supervisory functions turned on it draws 12 ìA, for a power consumption of 36 ìW. Another leading controller claims a sleep current of 0.5 ìA; but with supervisory functions turned on, it draws 61 ìA and consumes 152 ìW—50x what PSoC requires in the same application. This sort of ‘specmanship’ makes it difficult for designers to choose an embedded controller that will provide the results they need in their designs. About the PSoC Family Programmable System-on-Chip (PSoC) devices are high-performance, field-programmable, mixed-signal arrays for high-volume embedded-control functions in consumer, industrial, office automation, telecom and automotive applications.Containing over 100 reconfigurable analog and digital library components created from 12 fundamental analog and 8 digital blocks, PSoC CY8C27x devices are true systems on a chip. Each contains a 24 MHz 8-bit microcontroller unit (MCU); 16 kbytes of flash memory; 256 bytes of SRAM; an 8x8 multiplier with 32-bit accumulator; power and sleep monitoring circuits; and a precision real-time clock. All PSoC devices are dynamically reconfigurable, enabling designers to create new system functions on-the-fly. Being able to re-use the same silicon for different functions on different clock cycles, designers can achieve more than 120% utilization of the die in many cases. To further shorten design cycles, the PSoC family includes pre-programmed, specialized versions for lighting, energy, motor control, communications, automotive and battery applications. Each family member comes with a reference design and extensive application notes to speed application development. Software and Support The software development environment PSoC Designer 3.21 supports all current PSoC devices as well as future low-cost versions. PSoC Designer 3.21 is a full-featured, GUI-based design tool suite that enables the user to lay out their design on silicon with simple point and click options; code the MCU in either C or assembly language; and debug the design using sophisticated features such as event triggers and multiple break points while single-stepping through the code in C or assembler or a mix of the two. PSoC Designer 3.21 is free and can be downloaded at www.cypress.com/support/link.cfm?sd=designer321. The CY3205-DK Professional Class Development Kit includes a full-speed emulator with a large trace buffer, both of which seamlessly integrate with PSoC Designer 3.21. The development kit includes everything necessary to complete a design with the new PSoC family of ICs in DIP packages; the kits also contain all materials for the first four “Tele-training” modules. The tools are designed to keep the cost of development to a minimum while providing all the features found in tools that cost $2000 or more. The CY3205-DK is priced at $399. Early training is key to quickly realizing the cost saving and technical benefits of the PSoC architecture. Free “Tele-training” classes are offered live every week, with introductory training classes starting on Friday; sign up for training at www.cypress.com. A Fall and Winter regional seminar series is being scheduled; to find out when a PSoC seminar will held locally go to www.cypress.com/aboutus/events.cfm. Pricing and Availability The CY8C26x PSoC family is in full production and contains eight family members ranging from an 8-pin PDIP to a 48-pin SSOP—for as low as $1.99 in 50,000-unit quantities.
