Ref design launched for low power RF remote control
LONDON Ultra low power chip specialist GreenPeak (Utrecht, the Netherlands) is rolling out an IEEE802.15.4-based RF technology reference design that it says can be used to build home remote controls that can run almost forever on a single battery.
The RF remote control modules, which use the 2.4 GHz spectrum, are designed to be integrated into host gear such as TVs, DVDs and set-top boxes. They are based on GreenPeak's Emerald GP500C communication controller, with dedicated features for the consumer electronics and remote control market.
The designs also include IR as secondary use for legacy systems, so a single controller can be used for both IR and RF devices. They incorporate a protocol stack of less than 4KB. The embedded IEEE 802.15.4 MAC layer allows a short time to market and a simple, stable and reliable software application.
The designs are based on a single layer low cost PCB with integrated antennas guaranteeing a very low cost BOM. They will provide high speed low latency two-way communication with high throughputs, allowing high speed content browsing, touchpad operation, gaming, as well as high resolution displays on the remote control.
According to GreenPeak's CEO, Cees Links, the RF comms controller opens up a market for low cost, reliable high speed RF remote controls, "and is expected to have a huge impact on the user experience, as IEEE 802.15.4 remote controls will allow a completely new way to use a remote control."
The reference designs ill be demonstrated at the CES show taking place in January 2008 in Las Vegas.
