This issue of Digi-Key Daily recommends two products: STMicroelectronics' BlueNRG-LP Bluetooth low-power wireless SoC and Bourns' HCTSM8 series transformers.

Product 1: STMicroelectronics BlueNRG-LP Bluetooth Low Energy Wireless SoC

In IoT applications, BLE low-power Bluetooth is a widely used wireless interconnection technology. STMicroelectronics ' BlueNRG-LP is an ultra-low-power programmable BLE wireless SoC solution designed for such wireless interconnection applications.

The chip complies with the BLE SIG core specification version 5.2 and embeds STMicroelectronics' latest 2.4 GHz RF radio IP, which combines excellent performance with extremely long battery life. It can support point-to-point connections and Bluetooth Mesh networks, allowing large-scale device networks to be established in a reliable manner. At the same time, the chip is also suitable for 2.4GHz proprietary radio wireless communications to solve ultra-low latency applications.

BlueNRG-LP has built-in 256KB of programmable flash memory, up to 64KB of ultra-low latency RAM, a Cortex-M0+ microcontroller with a maximum operating frequency of 64MHz, and a DMA-based BlueNRG core coprocessor for BLE timing-critical operations, which has extremely wide application areas.
