Nordic Semiconductor has released a preview of its next- generation ANT wireless single chip solutions the nRF24AP2 family. The single-channel nRF24AP2 (nRF24AP2-1CH) will be a cost optimized product suitable for a wide range of simple wireless sensoring applications from bike cadence up to heart rate and blood glucose monitoring. The more advanced 8-channel nRF24AP2 product (nRF24AP2-8CH) will be specifically designed for ANT hubs with up to 8 active wireless sensor channels. This will allow products like sports watches, bike computers and gym machines to connect to up 8 different sensors or users simultaneously. The nRF24AP2 family provides a more than 20% reduction in peak current that yields a valuable extra power margin when working with small coin cell batteries. Average operating currents are expected to be reduced by close to 25% enabling a similar extension in typical battery operating lifetimes.
