STMicroelectronics Introduces STM32WB a High-Performing Multiprotocol Bluetooth & 802.15.4 System-on-Chip

STMicroelectronics flaunts 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.

Features Include:

• Radio can run other wireless protocols concurrently (more options for connecting devices to the Internet of Things (IoT))
• Compatibility with the STM32 development ecosystem (reduces time to market)
• SoC includes essential circuitry (balun) for connecting to the antenna
• Generous user and system memory
• Hardware encryption
• Customer-key storage for brand and IP protection

Today, only a few manufacturers offer similar dual-processor wireless chips capable of managing the user application and the radio separately for optimum performance, and with such large memory size. Alternatives typically utilize entry-level Arm Cortex-M industry-standard cores, which introduce architecture limitations.

“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.”
