You know we’re excited about Nordic Semiconductor’s nRF52832 system-on-chip, and we think you should be too – here’s what we’re looking forward to about using the nRF52 in our next module, the BMD-300.
Let’s start with the basics. The nRF52’s physical attributes make it versatile
and easy to integrate. It’s Nordic’s smallest SoC yet and has a true 1.8V operating range, and it can withstand a wider range of temperatures than the nRF51. The nRF52’s size allowed us to make our BMD-300 module half the area and a third of the volume of our nRF51-based module, the BMD-200. This SoC is built on a smart foundation – and it just gets better from there.
The nRF52 handles complex, multivalent processes with ease and minimal energy use, making it an ideal processor for multifunctional IoT devices. It’s built around an ARM®
Cortex™-M4F 64MHz 32-bit processor plus 512kB + 64kB RAM, and the IC supports DSP instructions, a FPU, single-cycle multiply and accumulate, and hardware divide.
A versatile SoC calls for versatile connectivity – the nRF52’s 2.4GHz radio supports multiple protocols including Bluetooth Smart, ANT and 2.4GHz proprietary. EasyDMA enables direct memory access during packet send and retrieve, and the radio’s high definition RSSI and automated functionality make it an efficient IoT component. It includes protocol stacks for Bluetooth Smart, ANT and Gazel (2.4GHz) software downloads provided by Nordic. Paired with the BMD-300’s complimentary software suite, which includes secure firmware updates, Android and iOS libraries, iBeacon and a UART bridge, the nRF52’s protocols allow for a versatile and easy-to-implement solution for IoT design.
The nRF52 SoC is extremely frugal with power. It offers users flexible power down functions for every individual peripheral and clock when not in use for task operation. The IC has a comprehensive set of automated and adaptive power management features that range across the entire IC’s operation from power supply switching to peripheral bus/EasyDMA memory management. It also includes an automated shut down of all but the essential peripherals required for a task.
With a comprehensive set of peripherals, the nRF52 is built to address diverse BLE development requirements. It features an on-chip NFC tag for OOB pairing, allowing for a flexible UX. A PDM Digital Microphone Interface allows for complex audio functions, such as voice control, and 12 PWM channels allow developers to create a unique UX with haptic feedback, LED sequences and other innovative UI components. The BMD-300 features all of the nRF52’s peripherals and allows for seamless, low-cost design.
The nRF52 represents possibility – its versatility makes it ideal for products in a number of industries, including…
- SmartHome automation
- computer peripherals
- voice-command remotes
- A4WP “Rezence” wireless charging
- Sports and fitness sensors and hubs
- Connected health products
- Smart watches
- RC toys
- Interactive games
- Building automation and sensor networks
And, of course, the Internet of Things. The nRF52 addresses a host of IoT design requirements, and with extremely efficient power management, it’s an ideal SoC for responsive devices. The BMD-300 incorporates the nRF52 into a turnkey solution for Bluetooth Smart design that reduces the time and money required for development. Connected environments, from home to car to office to entire city, can become the norm with the nRF52 and BMD-300.
