The STM32WB05xN is an ultra-low-power Bluetooth® LE wireless network coprocessor addressing standard Bluetooth® LE protocol. Interface with external microcontroller can be achieved through SPI and USART. It embeds STMicroelectronics’s state-of-the-art 2.4 GHz radio IPs, optimized for ultra-low-power consumption and excellent radio performance, for unparalleled battery lifetime. It is compliant with Bluetooth® LE. The STM32WB05xN embeds a Arm® Cortex®-M0+ microcontroller that can operate up to 64 MHz and also the BlueNRG core co-processor (DMA based) for Bluetooth® LE timing critical operations. The STM32WB05xN features standard and advanced communication interfaces: 1× SPI, 1× USART, . The STM32WB05xN operates in the -40 to +105 °C temperature range from a 1.7 V to 3.6 V power supply. A comprehensive set of power-saving modes enables the design of low-power applications. The STM32WB05xN integrates a high efficiency SMPS step-down converter and an integrated PDR circuitry with a fixed threshold that generates a device reset when the VDD drops under 1.65 V. The STM32WB05xN comes in different package versions supporting up to: 20 I/Os for the VFQFPN32 package, 20 I/Os for the WLCSP36 package. https://elecena.pl/product/26181298/stm32wb05knv6tr-ultra-low-power-2-4-ghz-network-processor-bluetooth-le-5-4-certified 2024-07-07 https://elecena.pl/product/26181298/stm32wb05knv6tr-ultra-low-power-2-4-ghz-network-processor-bluetooth-le-5-4-certified 2024-08-11 https://elecena.pl/product/26181298/stm32wb05knv6tr-ultra-low-power-2-4-ghz-network-processor-bluetooth-le-5-4-certified 2025-03-05 https://elecena.pl/product/26181298/stm32wb05knv6tr-ultra-low-power-2-4-ghz-network-processor-bluetooth-le-5-4-certified 2025-12-10 https://elecena.pl/product/26181298/stm32wb05knv6tr-ultra-low-power-2-4-ghz-network-processor-bluetooth-le-5-4-certified 2026-05-19 https://elecena.pl/product/26181298/stm32wb05knv6tr-ultra-low-power-2-4-ghz-network-processor-bluetooth-le-5-4-certified 2026-05-29 https://elecena.pl/product/26181298/stm32wb05knv6tr-ultra-low-power-2-4-ghz-network-processor-bluetooth-le-5-4-certified 2026-06-07 https://elecena.pl/product/26181298/stm32wb05knv6tr-ultra-low-power-2-4-ghz-network-processor-bluetooth-le-5-4-certified 2026-06-26 https://elecena.pl/product/26181298/stm32wb05knv6tr-ultra-low-power-2-4-ghz-network-processor-bluetooth-le-5-4-certified 2026-08-04
