Taiwanese module maker Raytac is using the nRF52832 wafer level-chip scale package (WL-CSP) System-on-Chip (SoC) from Nordic Semiconductor for two compact Bluetooth 5 modules.
The MDBT42V and MDBT42V-P modules provide developers of space-constrained Internet of Things (IoT), mesh networking, wearables, smart lighting, smart toys, industrial, and healthcare applications with a Bluetooth low energy wireless connectivity solution, without the need for RF design expertise.
The MDBT42V module measures 8.4 by 6.4 by 1.75mm with a high performance ceramic chip antenna delivering a wireless connectivity range of over 100m in open space according to Raytac. The MDBT42V-P comes in at 1.5mm thickness with a PCB-mounted antenna, and offers open space range up to 80m. Output power is adjustable up to +4dBm to boost RF range.
The Nordic SoC enables the module to provide up to 20 general-purpose input/outputs (GPIOs), as well as SPI, UART, I2C, I2S, PWM and ADC interfaces for connecting peripherals and sensors. It is also qualified over a -40° to 85°C industrial temperature range.
The nRF52832 device combines an ARM M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT, and proprietary 2.4GHz RF software) featuring -96dB RX sensitivity, with 512kB Flash memory and 64kB RAM. The WL-CSP package measures just 3.0 by 3.2mm.
The SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5 qualified RF software protocol stack for building advanced Bluetooth low energy applications. The S132 SoftDevice Central, Peripheral, Broadcaster and Observer Bluetooth low energy roles, supports up to twenty connections, and enables concurrent role operation.
“Thanks to the Nordic SoC, the MDBT42V offers superior RF performance, high reliability, and stability,” says Lyon Liu, Raytac Director. “However, it was not just a case of delivering RF performance, but also simplifying the customer’s production and design that was key in the selection of the nRF52832 SoC. We have built up a long-term relationship with Nordic, allowing Raytac to stay in touch with the latest wireless connectivity solutions available. This in turn means we can provide our customers with cost effective design flexibility, reliable quality control, and technical support.”
