Lattice Shrinks Design Footprint and Cost, Boosts Reliability in Embedded Systems with Single Wire Aggregation IP Solution
Solution Lets Developers Reduce the Number of Physical Connectors Required to Link Components and Boards in Systems
The connectors used to link circuit boards and modules in electronic systems are costly, take up valuable space in devices with tight form factors, and over time can degrade and negatively impact system reliability. Routing signals between multiple connectors on space-constrained circuit boards can create design challenges that increase overall time-to-market.
“Developers are always looking for innovative ways to simplify and accelerate the development of embedded systems, while still maintaining the lowest BOM cost possible. Our new SWA solution meets all three of these needs by reducing the number of connectors in a system,” said
Featuring the extremely low power and small size Lattice iCE40 UltraPlus™ FPGA, the SWA solution provides the hardware and software developers require to implement a single wire interface capable of aggregating multiple common I/O (I2C, I2S, UART and GPIO) data streams between components and circuit boards in a system. Lattice currently offers the following aggregated I/O configurations in pre-configured bitstreams for fast application prototyping.
- Two I2S, an I2C peripheral, an I2C controller, and eight GPIO signals
- Six I2C controller and two GPIO signals
- One I2C controller and 12 GPIO signals
- Three I2C controller, two I2C peripheral, and 15 GPIO signals
- One I2S, one I2C controller, one I2C peripheral, and eight GPIO signals
Lattice customers requiring customized configurations can source them directly from Lattice technical support at no charge.
