Broadcom has launched Bluetooth RF transceiver integrated SoC chip to power Internet of Things (IoT) devices from a coin cell battery for more than a year without recharge or replacement of battery. The Smart Bluetooth SoC allows peripherals such as heart rate monitors, pedometers, door locks, lighting, proximity alarms to connect to hand held computers and any other computer hardware wirelessly using Bluetooth. Broadcom also announced the contribution of its Bluetooth software stack, including classic Bluetooth and Bluetooth Smart (formerly Bluetooth Low Energy) technology, to the Android Open Source Project (AOSP). Broadcom is trying to create the eco-system for its chips to get used in IoT applications.
ARM Cortex M3-based BCM20732 enables products to operate for more than one year without recharging the small batteries that power them.
Key Features of BCM20732:
Bluetooth Smart compliant single mode low energy solution
Integrated ARM CM3 microcontroller unit (MCU), radio frequency (RF) and Embedded Bluetooth Smart Stack all on a single chip
Full software support, including GATT, profiles, stack, APIs and application software development kit (SDK)
Power optimized for single mode coin cell operation and from 1.2V supply
On-chip support for 2 serial peripheral interfaces (SPIs)
On-board 12-bit analog to digital converter (ADC)
On-board wakeup timer
Designed for fast ramp, easy manufacturing with 5x5 mm quad-flat no-leads (QFN) packaging
Availability: The Broadcom BCM20732 is currently sampling with evaluation boards (EVBs) and SDKs and is available in volume production.
