CyFi = PSoC CyFi Star Network Protocol CyFi Transceiver PSoC Programmable System-on-Chip PSoC devices combine dynamic, configurable analog and digital blocks and an 8-bit MCU on a single chip, enabling designers to build complete wireless embedded systems with fewer components and shorter design cycles. PSoC devices are the heart of a CyFi solution, running the application, the protocol and driving the CyFi transceiver. A CyFi solution utilizes any of the available PSoC devices or PSoC-based solutions (like CapSense, TrueTouch, EZ-Color, nvPSoC and more) as long as there is one available digital block and sufficient flash available to run the application. Flash requirements for CyFi solutions are extremely minimal compared to other embedded wireless solutions so you have a wide array of PSoC devices to choose from (as little as 8KB or 5KB required for a hub or node application, respectively).

The easiest way to get started is to develop your application in PSoC Designer using the largest PSoC device available. Once you have all of the discrete components integrated into your PSoC project that your application requires you can then better select the perfect PSoC device for your application. PSoC Designer makes this very simple to do by enabling you to change your target PSoC device within the software.

CyFi Transceiver

The CyFi Transceiver is the muscle behind the CyFi solution. The PSoC device will run the protocol and the application while controlling the CyFi transceiver and ensure it best utilizes the many features of the transceiver to ensure reliable and power-efficient communications between the devices in your system.

The CyFi Transceiver features:

> 2.4-GHz ISM Band Transceiver
> Direct Sequence Spread Spectrum Modulation
> 1 Mbps, 250 Kbps, and 125 Kbps data rates
> 80 discrete, 1-MHz channels
> Up to 4 dBm output power (on-chip)
> Up to -97 dBm receive sensitivity
> I/Os and control for off-chip power amplifiers

CyFi Star Network Protocol Stack

The CyFi Star Network Protocol Stack is the brain of a CyFi Solution. The protocol is run on the PSoC device and composes the algorithms and actions that the PSoC follows to drive the CyFi transceiver and maximize reliability and power-efficiency in a wireless system. This protocol stack is available in PSoC Designer as a simple, drag-and-drop user module. The protocol consists of a very simple API that enable you to quickly and easily implement an ultra-reliable and power-efficient solution in just minutes. The protocol has been designed with the following features:

> Support for up-to 250 wireless nodes
> Bidirectional communications (Node-to-Hub and Hub-to-Node)
> Active link and power management
> Power-optimization for coin-cell, low-impedance batteries and wall-powered devices
> Simple network commissioning
