STMicroelectronics has unveiled two new entries in its STM32 vary of microcontrollers: the STM32WBA6, which might add short-range wi-fi connectivity to sensible house and industrial management techniques, and the ultra-low-power STM32U3 that targets prolonged maintenance-free operation.
“Strong and standardized wi-fi connectivity is central to the IoT’s [Internet of Things’] success,” claims STMicro’s Patric Aidoune in assist of the corporate’s newest launches. “Our new STM32WBA6 MCUs convey richer options and bigger reminiscence to handle high-end functions in sensible house, well being, manufacturing unit, and agriculture. Our clients can now improve the tempo of growth to satisfy calls for from shopper and industrial markets for brand new merchandise that ship extra options and elevated capabilities inside diminished measurement and energy constraints.”

The STM32WBA6 microcontroller vary comes with an Arm Cortex-M33F core with digital sign processing (DSP) directions, operating at as much as 100MHz, as much as 512kB of static RAM (SRAM), and as much as 2MB of flash storage on-chip. The radio aspect of the design helps Bluetooth Low Power (BLE) plus IEEE 802.15.4 requirements together with Zigbee, Thread, and the cross-vendor Matter — although single-protocol variants with solely BLE assist can be found at a decrease value, STMicro has confirmed. Peripherals embrace three SPI ports, 4 I2C ports, three USARTs, and one LPUART — plus the same old general-purpose enter/output (GPIO) connectivity.
The STM32U3, in the meantime, is designed for ultra-low-power functions, the place it may be left operating for lengthy intervals of time with out intervention. “The STM32U3 sequence builds on the heritage of ST-established ultra-low-power general-purpose microcontroller class as it’s identified right this moment, which opened the door to widespread diffusion of sensible expertise in various environments,” Aidoune claims. “Leveraging revolutionary methods similar to latest developments in near-threshold design, the brand new units minimize dynamic energy consumption to the bone, boosting effectivity by an element of two in comparison with our earlier era, therefore contributing to corporations’ sustainability targets.”

The STM32U3 household incorporates a single Arm Cortex-M33 core operating at as much as 96MHz and delivering a claimed Coremark-per-milliwatt rating of 117 — double that of the STM32U5, and 5 occasions the effectivity of the STM32L4. There’s as much as 256kB of SRAM and as much as 1MB of flash reminiscence obtainable, model-dependent, and the chips embrace the identical safety features as the sooner STM32U5 however with first-of-its-kind assist for STMicro-loaded key storage protected by a coupling and chaining bridge (CCB). A cryptographic accelerator can be included within the design, however as with the multi-protocol radio within the STM32WBA6 components are additionally obtainable with out it for cost- and power-reduction causes.
Each the STM32WBA6 household and the STM32U3 household at the moment are in quantity manufacturing, STMicro has confirmed, with pricing beginning at $2.50 and $1.93 respectively in 10,000-unit portions.
