STMicro STM32WBA6 2.4 GHz wireless MCU gets up to 2MB flash, 512KB SRAM, USB OTG, and more

STMicro had two announcements yesterday. I’ve already covered the launch of the ultra-low-power STM32U3 microcontroller family, so today, I’ll check the new 100 MHz STM32WBA6 Cortex-M33 wireless MCU family with 2.4GHz radios for Bluetooth LE 6.0, Zigbee, Thread, and Matter designed for wearables, smart home devices, remote weather sensors, and more. The STM32WBA6 is an evolution of the STM32WBA family introduced last year, especially of the STM32WBA54 and STM32WBA55 with many of the same features SESIP (Security Evaluation Standard for IoT Platforms) Level 3 security certification, but gets more memory and flash with up to 512KB of SRAM and up to 2MB of flash. The new STM32WBA6 family also gains a High-Speed USB OTG interface and extra digital interfaces such as three SPI ports, four I2C ports, three USARTs, and one LPUART. STMicro STM32WBA6 key features and specifications: MCU core – Arm Cortex-M33 at 100MHz with FPU and DSP Memory […]

Silicon Labs MG26 development kits and SoCs are now available for Matter and multiprotocol Smart Home applications

Silicon Labs MG26 is a new family of Arm Cortex-M33 wireless SoCs designed for Matter or multiprotocol Smart Home applications that provide an update to the MG24 with more memory and storage, additional GPIO, a 4×40 LCD controller, and an integrated AI/ML accelerator. We first covered the new wireless microcontroller family in April 2024, but the company has now published a new press release announcing the general availability of the MG26 microcontrollers, and I also noticed some development kits were now available, so we’ll check those out in this post. Silicon Labs MG26 specifications A reminder of the SoC specifications with highlights in bold showing the improvements or differences against the MG24 family: MCU core – Arm Cortex-M33 @ 78.0 MHz with DSP instruction and floating-point unit Memory – Up to 512 kB RAM data memory Storage – Up to 3200 kB flash program memory AI/ML accelerator – Matrix Vector […]

Ceva-Waves Links200 IP supports Bluetooth LE High Data Throughput (HDT) up to 7.5 Mbps, 802.15.4 for Zigbee, Thread and Matter

Ceva has recently unveiled the Ceva-Waves Links200 multi-protocol platform IP with support for Bluetooth LE High Data Throughput (HDT) technology up to 7.5 Mbps and IEEE 802.15.4 for Zigbee, Thread, and Matter designed for TSMC’s low-power 12nm process. Released in 2016, Bluetooth 5 upgraded Low Energy implementation with four times the range and twice the speed of Bluetooth 4.0 LE transmission which meant up to 2 Mbps over BLE, and even the latest Bluetooth 6.0 specification does not change that. There’s just a new LE 2M 2BT physical layer for Bluetooth Channel Sounding. So I was intrigued when the press release of the Links200 further read: Addressing the rising market demand for faster, more efficient Bluetooth connectivity, particularly for low-power audio and latency-sensitive IoT applications, the breakthrough High Data Throughput mode more than doubles the speed of traditional Bluetooth, delivering a data rate of up to 7.5 Mbps. For this […]
