Software puts programmable
SoCs into modem designs
New software from Cypress MicroSystems enables embedded designers to easily add modem connectivity to systems based on its PSoC programmable system on chip device family
PSoC products are based on a configurable mixed-signal array with an onboard controller, providing a low-cost, single-chip solution for a variety of consumer, industrial and control applications. Embedded designers can now leverage the flexibility of the PSoC architecture to add connectivity to their systems without increasing costs and component inventory.

Using free development software, designers can create multiple configurations on a single device and switch between them on the fly.
This dynamic reconfiguration enables designers to reuse the chip's analogue and digital resources to create a modem that extends the capabilities of a device without impacting its ability to perform the primary application.
For example, a PSoC device can be configured to take measurements in a system, dynamically reconfigure itself into a modem to transmit data, and then reconfigure itself back into a measurement system.
Cypress MicroSystems further simplifies modem implementations with PSoC Designer, the integrated development environment used to configure the resources inside of a PSoC device with a few clicks of a mouse.
The software offers a broad library of pre-built "user modules", which automatically configure the chip's internal hardware resources and create the application programming interface (API) software for commonly used peripheral functions.

Designers can take advantage of the intelligence built into the user modules to easily configure a PSoC device to perform the functions necessary for a modem.
"Built-in modem capabilities can turn common devices into intelligent appliances that communicate over standard phone networks", said John McDonald, Vice President of Marketing for Cypress MicroSystems.
"With the ability to report data into a central repository, machines such as vending machines, pay telephones, ATMs and control instrumentation can be remotely monitored and maintained.
The reprogrammable PSoC hardware and powerful software simplify modem implementations and bring cost-effective connectivity to virtually any embedded design".
Modem connectivity has traditionally required multichip microcontroller-based solutions with many additional components, due to the resource-intensive and mixed-signal nature of a modem.
In contrast, designers can use the new PSoC modem configuration, combined with a minimal amount of external passive circuitry, to create a Bell 103 and V.21-compatible modem.
The Bell 103 and V.21 standards are used in embedded applications where the number of bytes transferred is low and the speed to establish the connection is the most important performance factor.
The PSoC device family integrates programmable blocks of analogue and digital logic, a fast 8bit CPU, 8 to 16Kbyte of Flash memory and 256byte of SRAM.
PSoC provides designers with a flexible architecture that can be configured for a broad range of embedded applications and dynamically reconfigured to extend the capabilities and value of their product.
The PSoC platform typically reduces customer development time by 33% and lowers bill of material costs by an average of $5, by significantly reducing the number of chips required for solutions utilising a traditional microcontroller and discrete digital and analogue components.
The PSoC CY8C26xxx family is currently available for 1000-unit pricing of $2.80 to $4.55.
All PSoC devices include the free PSoC Designer software toolset, an integrated development environment.
Customers may also purchase a basic development kit, including the PSoC ICE-4000, for $248.
