描述

The ISP4520 offers a unique combination of two leading IoT radio technologies in one class leading miniaturized package. With integrated BLE and LoRa connectivities, this module offers the long-range capability of LoRa for data transmission over distance, combined with the high-throughput flexible service of BLE for a more local connection that can be used to carry out configuration, commissioning and update via smartphone or tablet applications. The module incorporates chips from the leading semiconductor vendors for each technology – Nordic Semiconductor for BLE and Semtech for LoRa. Processing power is provided by the Nordic nRF52’s onboard M4 floating point processor, with 512K of flash memory available for advanced applications. The Semtech SX1261 (for EU and AS versions) or SX1262 (for US version) provide the LoRa radio function. Both semiconductors offer best in class low power consumption, coupled with an array of power saving features, allowing for multi-year coin-cell operation. The module integrates antennas for both LoRa and BLE transmission, thus allowing this device to be a pre-certified complete radio and application core solution, requiring only external sensors, or connection to a customers existing device. The module is supplied with a combined BLE and LoRaWAN stack.
