After the success of its ISP4520 RF module which extended its product portfolio to include Long Range Networking via LoRa technology, Insight SiP has launched the ISP1907-LL RF module, designed for classic IoT applications which require Bluetooth 5.1 standard communication for Long Range and Direction-Finding connectivity.
At an ultra-miniature size of 8x8x1mm with its integrated antenna, the ISP1907-LL RF module provides huge computing capability coupled with best-in-class battery life, with power consumption around 20-50% lower than previous generations of technology, making this Bluetooth Low Energy / BLE module a ready to use solution for most IoT applications with connected sensors for medical, healthcare, sport, fitness and industrial devices as well as home automation and beacons. The ISP1907-LL’s Long Range capabilities enable wireless connectivity over an open field range of up to 400 meters between modules.
The RF module on the ISP1907-LL is based on the nRF52811 Nordic Semiconductor 2.4GHz wireless System on a Chip (SoC) integrating a 2.4GHz transceiver, a 32-bit ARM Cortex-M4, with 192kB flash memory, and 24 kB SRAM and analogue and digital peripherals.
The ISP1907-LL supports multiple protocols including BLE, ANT/ANT+, Thread, Zigbee and a range of proprietary 2.4GHz protocols including Gazell from Nordic Semiconductor. It also supports a wide range of stacks which you can download for free. These stacks include fully qualified BLE stacks for the nRF52 SoC which operate with S112/S132 SoftDevices.
Like all of Insight SiP’s products, the ISP1907-LL is a fully featured BLE device with embedded 32MHz Radio and 32KHz Synchro crystals, a fully integrated RF matching and Antenna and DC-DC convertor including inductor, thus delivering maximum power saving efficiency. A full set of interfaces is supplied with the device for analogue or digital peripherals including 13 GPIOs including 3 ADCs, an analogue to digital convertor, and SPI, PDM I2C and UART buses. It offers pin compatibility with the ISP15, 18 and 19 series.
Michel Beghin, CEO of Insight SiP said: “The new ISP1907-LL is ideal for customers looking for an ultra miniature RF module to support straight-forward applications that need Bluetooth 5.1 for Long Range and Direction-Finding connectivity over long distances. In addition, we look forward to extending the ISP1907 RF module range in the near future to support complex applications which require greater performance and memory.”
The ISP1907-LL RF module is designed to run on a coin cell battery. Thanks to the module’s ultra-low power consumption and advanced power management system, the battery can last up to several years
Module prototypes are available now. Mass production of the modules will start in Q4 2019. Certification is pending. To support product developers, Insight SiP offers a complete development kit together with sample software that provides everything required out of the box to start developing a solution on day one.
