New Low Power Bluetooth 4.2 Qualified IoT Devices


The latest Bluetooth 4.2 standard qualified solution from Microchip is ideally suited for Internet of Things (IoT) and Bluetooth Beacon applications, making it easier for designers to take advantage of the low power consumption and simplicity of Bluetooth Low Energy (LE) connectivity.

Referring to the press release, Microchip has unveiled its latest IS1870 and IS1871 Bluetooth LE RF ICs, along with the BM70 module. As stated in the release, the new Bluetooth LE devices include an integrated, certified Bluetooth 4.2 firmware stack. Using the solution from Microchip, developers can expect up to 2.5 times faster data transfer speeds and greater connection security, with government-grade (FIPS-based) secure connection support, as mentioned.

In addition, data is sent and received over the Bluetooth link using Transparent UART (universal asynchronous receiver/transmitter) mode, making it easy to integrate with any processor or the hundreds of Microchip’s PIC microcontrollers that have a UART interface. The module also supports standalone “hostless” operation for beacon applications. Adding further, the optimised power profile of these new devices minimises current consumption for extended battery life, in compact form factors as small as 4×4 mm for the RF ICs and 15×12 mm for the module. The module options include RF regulatory certifications, or non-certified (un-shielded/antenna-less) for smaller and more remote antenna designs that will undergo end-product emission certifications, as mentioned.


“The IS1870 and IS1871 ICs bring cutting-edge Bluetooth 4.2 performance to our chip-down customers, and our BM70 module enables customers to avoid the expense and product delays caused by regulatory certifications,” said Sumit Mitra, vice president of Microchip’s Wireless Solutions Group.

According to the press release, the IS1870 and IS1871 Bluetooth LE RF ICs is priced for US$ 1.79 (in a 6×6 mm, 48-pin QFN package)and US$ 1.76 (in a 4×4 mm, 32-pin QFN package) in 1,000 unit quantities, respectively. Apart from this the 30-pin BM70 Bluetooth LE modules are worldwide available (with or without built-in PCB antennas) for a starting price of US$ 4.99 each in 1,000-unit quantities.
