STMicroelectronics launched the STM32W microcontroller family. The STM32W microcontrollers feature an integrated IEEE 802.15.4 radio. The new MCU family is ideal for embedded wireless sensor network design. The STM32W family is available in a 6 x 6mm 40-pin QFN package pin-to-pin compatible with the SN260, or a 7 x 7mm 48-pin QFN compatible with the SN250. Pricing starts at $2.90 for quantities over 100,000 units with ZigBee PRO feature-set.
The ST STM32W microcontroller family implements the IEEE 802.15.4 physical (PHY) layer as well as the Media Access Control (MAC) layer, giving developers the flexibility to target ZigBee-compliant specifications or to build any network wireless protocol which interfaces with the standardized IEEE 802.15.4 MAC. Other protocols include ZigBee RF4CE for radio-frequency remote controls or 6LoWPAN for wireless embedded Internet solutions. Software support for the STM32W family includes libraries for the latest ZigBee PRO specification, as well as ZigBee RF4CE, and the IEEE 802.15.4 MAC.
The STM32W devices combine the benefits of a best-in-class radio platform with the added performance, flexibility and scalability of the STM32 microcontroller architecture. The STM32 portfolio is the industry’s leading microcontroller product range featuring the advanced 32-bit ARM Cortex-M3 processor, and it was the first to eliminate all obstacles to broad 32-bit usage in embedded applications. Advantages such as high processing performance, advanced power management and high integration, as well as real-time behavior, have attracted large numbers of developers to the STM32 platform, worldwide.
The STM32W is a true SoC combining best-in-class IEEE 802.15.4 RF performance as well as 32-bit processing. The devices can transmit up to 7dBm output power and support up to 107dB link budget, achieve up to -100dBm receiver sensitivity, and allow coexistence with nearby Wi-Fi and Bluetooth networks, which also operate in the 2.4GHz frequency band.
