STMicroelectronics has launched the STM32WB55xx and STM32WB35xx collection of MCUs providing excessive efficiency at very low energy and price.
The STM32WB55xx and STM32WB35xx multiprotocol wi-fi and ultra-low-power gadgets embed a robust and ultra-low-power radio compliant with the Bluetooth Low Vitality SIG specification 5.3 and with IEEE 802.15.4-2011. They include a devoted Arm Cortex-M0+ for performing all of the real-time low layer operations.
The gadgets are designed to be extraordinarily low-power and are primarily based on the high-performance Arm core working at a frequency of as much as 64 MHz. This core contains a Floating level unit (FPU) single precision that helps all Arm single-precision data-processing directions and information sorts. It additionally implements a full set of DSP directions and a reminiscence safety unit (MPU) that enhances software safety.
Direct information switch between reminiscence and peripherals and from reminiscence to reminiscence is supported by fourteen DMA channels with a full versatile channel mapping by the DMAMUX peripheral. The gadgets function a number of mechanisms for embedded flash reminiscence and SRAM: readout safety, write safety and proprietary code readout safety. Parts of the reminiscence will be secured for Cortex -M0+ unique entry.
The 2 AES encryption engines, PKA, and RNG allow decrease layer MAC and higher layer cryptography. A buyer key storage function could also be used to maintain the keys hidden. The gadgets provide a quick 12-bit ADC and two ultra-low-power comparators related to a excessive accuracy reference voltage generator. These gadgets embed a low-power RTC, one superior 16-bit timer, one general-purpose32-bit timer, two general-purpose 16-bit timers, and two 16-bit low-power timers.
