STMicro’s New STM32WB09 Goals to Get You Up and Operating with New Bluetooth 5.3 Low Vitality Options

STMicroelectronics has introduced a brand new microcontroller, with module and analysis board to match, which it hopes will make it simpler to get began designing sensible Bluetooth 5.3 Low Vitality (BLE) units: the STM32WB09 microcontroller and STM32WB1MMC module.

The STM32WB09 is a radio-equipped microcontroller constructed across the Arm Cortex-M0+ core operating at 64MHz, with 64kB of static RAM (SRAM) and 512kB of flash reminiscence on-chip. Whereas it enters into the prevailing STM32WB0 household, the ’09 is claimed to incorporate particularly tailor-made reminiscence and peripherals for wi-fi sensing, related wearables, and distant management initiatives.

The radio within the system-on-chip is, STMicro says, absolutely suitable with the superior options of the Bluetooth 5.3 Low Vitality customary — which suggests help for course and distance discovering for real-time location monitoring, indoor positioning, and item-finding functions, with energy management opens for 1dBm-step radio output to spice up battery life and scale back interference in a congested spectrum.

On the microcontroller aspect, the chip gives as much as 20 general-purpose enter/output (GPIO) pins, all able to waking the chip from sleep and boasting 5V tolerance, a 12-bit analog to digital converter (ADC) with eight enter channels, SPI with I2S multiplexed, I2C, USART, low-power UART, a real-time clock, one 16-bit four-channel and two 16-bit two-channel general-purpose timers, and infrared interface, battery monitoring, an analog watchdog, and Serial Huge Debug (SWD) help.

For individuals who do not fancy making an attempt to construct a board round a naked chip, the brand new half can be obtainable because the STM32WB1MMC module. This combines the licensed microcontroller with all of the required exterior parts to get the radio up and operating. For the quickest of potential begins, in the meantime, there’s the B-WB1M-WPAN1 analysis board — which is ready-to-go out of the field, STMicro guarantees, and contains movement, temperature, and strain sensors on-board.

STMicro has confirmed pricing for the STM32WB09 chip at $1.36 in a QFN32 package deal for “high-volume OEM [Original Equipment Manufacturer]” prospects, and the STM32WB1MMC module at $5.32 in 10,000-unit portions; the event board, in the meantime, is priced at $30 — in, fortunately, single-unit quantity. Extra info is out there on the STMicro web site.
