New PSoC® Solution for Digital Filters Offers Higher Performance and More Flexibility than MCU-Based Offerings

Business Wire
Cypress Semiconductor Corp. (Nasdaq: CY) today announced a
digital filtering solution based on its PSoC® 3 and PSoC 5
programmable system-on-chip families. The new solution, available
free through a software “Component Pack” upgrade from Cypress,
enables designers to quickly and easily design and customize
digital filters with higher performance than any MCU solution. The
hardware digital filter co-processor integrated in the PSoC 3 and
PSoC 5 devices combined with the easy-to-use PSoC Creator software
enable advanced FIR or IIR digital filter implementations, AC noise
rejection and many other filtering applications.
Digital filters have many applications, often involving the
removal of a signal that interferes with system performance, or the
isolation of a necessary signal. PSoC 3 and PSoC 5’s hardware
filter implementation allows higher performance than is possible
from any MCU-only solution. It can clean up and isolate even very
weak signals, enabling small sensors to operate efficiently, and
extracting modulated data in voice and communications systems.
The new filtering solution is available as a drop-in “component”
from Cypress’s PSoC Creator™ 2.0 design software. It was recently
released in a “Component Pack” update that includes new peripheral
functions. The ability to add new peripheral functions to existing
devices is a unique advantage of PSoC’s programmability. Cypress
plans to deliver new Component Packs every eight weeks providing
unmatched time-to-market.
The digital filter component is fully tested and characterized,
speeding time-to-market and assuring high quality end products for
customers. It enables easy drag-and-drop addition of powerful
hardware digital filters to PSoC Creator project schematics. It
offers two independent filter channels, each of which can have up
to four separately designed FIR or IIR stages in series. Customers
can choose built-in standard window filter types or enter custom
filter coefficients for maximum flexibility. Final
hardware-optimized coefficient values as well as the graphical
views of the expected results can be extracted for further
analysis.
The digital filter solution is highlighted as the current PSoC
Peripheral of the Month, a program designed to highlight
applications and functions that standard MCUs can’t deliver, but
PSoC can. Each peripheral will be presented with accompanying
design support documents at www.cypress.com/go/potm. At the page,
customers can learn more and download PSoC Creator free of charge
and begin development of high-performance digital filtering
applications immediately.
“Filters are ubiquitous elements in a variety of systems, from
consumer to embedded,” said Jim Davis, Sr. Marketing Manager for
Cypress’s PSoC Platform. “But it’s a function that MCUs
traditionally do not perform well. PSoC’s unique architecture
blends the performance of a hardware co-processor utilized for
digital filter applications with the ease-of-use introduced by the
PSoC Creator software toolset. This combination enables integrated
and innovative solutions for engineers that also accelerate their
time to market.”
Availability
The digital filter component is available in a free download of
Cypress’s Component Pack 1 for existing PSoC Creator 2.0 users.
Users downloading PSoC Creator 2.0 for the first time will
automatically receive the Component Pack. Going forward, registered
users will receive alerts when new Component Packs are released.

About PSoC 3 and PSoC 5
The new PSoC 3 and PSoC 5 architectures include high-precision
programmable analog capability (up to 20-bit resolution for an
Analog to Digital Converter) and expanded programmable digital
resources integrated with powerful, industry-standard MCU cores and
ample memory and communications peripherals. The PSoC 3 devices are
based on a new, high-performance 8-bit 8051 processor, while the
PSoC 5 devices include a powerful 32-bit ARM Cortex™-M3 processor.
The new products provide designers with a seamless, programmable
design platform, enabling easy migration from 8 to 32 bits. The
robust features of these new solutions dramatically expand the
applications and markets that PSoC can address, including
automotive, portable medical, industrial and many more. More
