Microchip Technology Inc. has rolled out its next-generation Bluetooth Low Energy (LE) solutions qualified to the latest Bluetooth 4.2 standard. The IS1870 and IS1871 Bluetooth LE RF ICs, along with the BM70 module, expand Microchip's existing Bluetooth portfolio and carry both worldwide regulatory and Bluetooth Special Interest Group (SIG) certifications. The devices are aimed at Internet of Things (IoT) and Bluetooth Beacon applications.

Bluetooth Low Energy (LE) solutions

Microchip's Bluetooth LE devices include an integrated, certified Bluetooth 4.2 firmware stack. Developers can expect up to 2.5 times faster data transfer speeds and greater connection security, with government-grade (FIPS-based) secure connection support. Data is sent and received over the Bluetooth link using Transparent UART mode, making it easy to integrate with any processor or the hundreds of Microchip's PIC MCus that have a UART interface. The module also supports standalone hostless operation for beacon applications.

The optimised power profile of these devices cut current consumption for extended battery life, in compact form factors as small as 4mm x 4mm for the RF ICs and 15x12 mm for the module. The module options include RF regulatory certifications, or non-certified (unshielded/antenna-less) for smaller and more remote antenna designs that will undergo end-product emission certifications.
