STMicroelectronics Release New Dual Core 32-bit Microcontroller with Integrated Bluetooth & 802.15.4 System-on-Chip


The Dual ARM® Cortex®-M Cores are individually dedicated to operation and wireless communication, for improved performance and longer battery life


STMicroelectronics has released an advanced dual-processor wireless chip that supports new features and enhanced performance with extended battery life to deliver an improved end-user experience. The new STM32WB wireless System-on-Chip (SoC) devices combine a fully-featured Arm® Cortex®-M4-based microcontroller to run the main application as well as an Arm Cortex-M0+ core to offload the main processor and offer real time operation on the Bluetooth Low Energy (BLE) 5 and IEEE 802.15.4 radio. The radio can also run other wireless protocols concurrently, including OpenThread, ZigBee®, or proprietary protocols, giving even more options for connecting devices to the Internet of Things (IoT).

Alternatives typically utilize entry-level Arm Cortex-M industry-standard cores, which introduce architecture limitations.

Combining the higher-performing Cortex-M4 with a Cortex-M0+ for network processing, the STM32WB leverages ST’s ultra-low-power MCU (microcontroller) technologies to combine superior RF performance for longer battery life. The SoC also includes essential circuitry (balun) for connecting to the antenna, which engineers must usually design themselves, as well as generous user and system memory, hardware encryption, and customer-key storage for brand and IP protection.

Click for Larger Image - Microchip Releases New MCP19214 “The STM32WB series delivers the advanced integration and uncompromising dual-core performance that developers now need to meet relentless end-user demands for even better and more affordable smart connected objects,” said Michel Buffa, Group Vice President, Microcontroller Division General Manager, STMicroelectronics. “Moreover, compatibility with the STM32 development ecosystem brings design advantages that can significantly reduce time to market for new products like lights, fitness trackers, medical monitors, beacons, tags, security devices, and many others.”
