United States : The New ST BlueNRG Processor Available from Mouser Makes Bluetooth Easy

June 10, 2014

Mouser Electronics, Inc. is now shipping the new BlueNRG Bluetooth Low Energy Wireless Network Processor from STMicroelectronics. The BlueNRG is built around the ARM Cortex?M0 processor architecture with an on?chip 2.4 GHz Bluetooth RF transceiver, and is compliant with the very low power Bluetooth Low Energy (BLE) specification.

The new STMicroelectronics BlueNRG Bluetooth Low Energy Wireless Network Processor, available from Mouser Electronics, is a single chip processor and Bluetooth 4.0 RF transceiver. The entire Bluetooth low energy stack runs on the embedded Cortex?M0 core. 64KBytes of Flash memory allows the Bluetooth stack to be upgraded in the field, and the on?chip 12KBytes of RAM provides plenty of overhead for running the BLE stack in a high traffic environment. The on?chip RF transceiver is compliant to the Bluetooth 4.0 specification and to regulations for transmitting over the unlicensed 2.4 GHz band. To speed product approval, the transceiver is compliant with the following RF regulations: ETSI EN 300 328, EN 300 440, FCC CFR47 Part 15, and ARIB STD-T66. The RF transceiver requires very few external components while keeping peak current below 15 mA.

With multiple low power sleep modes, the STMicroelectronics BlueNRG allows designers to build low power Bluetooth applications that can even run off coin cell batteries. To enable low power operation, the BlueNRG integrates both a low dropout voltage regulator (LDO) and a step?down DC?DC converter, either of which can be used to power the BlueNRG chip.

The BlueNRG can operate as a standalone processor, or can interface to an external microcontroller through a standard SPI interface. Applications for the STMicroelectronics BlueNRG Bluetooth processor include Internet of Things devices, fitness and wellness devices, consumer medical devices, security systems, industrial automation applications, and mobile phone peripherals.
