Bluetooth low energy SoC transitions quickly between power-saving and active modes

Mouser now stocks the BlueNRG-1 system-on-chip (SoC) from STMicroelectronics. The device contains a Bluetooth low energy radio optimized to satisfy high-volume opportunities in the fast-growing Bluetooth low energy (Bluetooth Smart) market through the combination of superior energy efficiency and strong radio performance. It’s ability to transition quickly between power-saving and active modes extends battery life from months to years in low-power smart sensors and connected devices like wearables, retail beacons, keyless entry systems, smart remote controllers, asset trackers, and industrial and medical monitors. The wireless SoC features a 32MHz 32-bit ARM Cortex-M0 core and delivers performance and efficiency for targeted applications. The SoC also includes 160kB of on-chip flash memory, allowing designers to embed both the Bluetooth Low Energy 4.2 protocol stack and the application code; 24kB of static RAM with retention (in two 12kB banks); and SPI, UART, I2C standard communication interface peripherals. The device benefits from an ultra-low-power design, including support for fast wake-up and sleep transitions, and sub-1µA standby current. In addition to the device’s excellent link budget up to 96dB, RF-output power is boosted to +8 dBm to ensure clear and reliable communication for optimum efficiency, even in noisy environments. The SoC is compliant with a range of RF regulations, including ETSI EN 300 328, EN 300 440, FCC CFR47 Part 15, and ARIB STD-T66.
