Introduction

The HumPROTM Series is an RF transceiver designed for the reliable transfer of digital data. It incorporates a Listen Before Talk (LBT) and Adaptive Frequency Agility (AFA) algorithm that meets the ETSI requirements for 64% duty cycle transmissions in the 868MHz band. It has a very fast lock time so that it can quickly wake up, send data and go back to sleep, saving power in battery-powered applications. The module has several features that increase the data transfer reliability. It ensures that no other modules are transmitting before it begins transmitting data. Automatic acknowledgements ensure that the remote side received valid data. Multiple hopping patterns enable several systems to operate in proximity without interference. A standard UART interface is used for module configuration and data transfer. A few simple serial commands are all that are needed for configuration. All modules have a unique 32-bit serial number that can be used as an address. Source and destination addressing support point-to-point and broadcast links. Address masking by the receiving module allows for creating subnets. Other network topologies can also be implemented. Housed in a tiny compact reflow-compatible SMD package, the transceiver requires no external RF components except an antenna, which greatly simplifies integration and lowers assembly costs.
