SmartleWiS
PmA 51xx family
An associated Software function library provides powerful functions like AeS encryption. The combination with state-of-the-
art software development tools makes rf easy to use for everyone, allowing simple and fast time-to-market. Additionally, with
only a few external components, you can build a running system. The advanced power control system makes this family ideal
serves a wide temperature range and perfectly suits applications for rough environment and high quality requirements.
Test the PmA 71xx/51xx uSB rf kit! it contains everything you need and it takes just a few steps to run.
