MCU has Cortex-M3, IEEE 802.15.4 radio

The STM32W wireless microcontroller has a Cortex-M3 processor core plus a certified 2.4 GHz IEEE 802.15.4 radio implementation. It supports emerging industry-standard Smart Energy 2.0 protocol (SEP 2.0) and use an IPv6-based stack (ZigBeeIP) for extended interoperability.

The device has up to 256 Kbytes of flash along with an encryption accelerator, two 16-bit timers, and a 12-bit A/D converter. It runs at 6, 12, or 24 MHz from a single 2.1 to 3.6 V supply. Receive current is 27 mA total, transmit current at +3 dBm is 31 mA, and deep sleep current, with retained RAM and GPIO, is 400 nA. (Ea./1,000; $2.05 with 64 Kbyte flash; $2.91 with 256 Kbyte flash – samples available now.)
