The KW40Z is a highly-integrated single-chip device that enables Bluetooth®
Smart/Bluetooth® Low Energy v4.1 and IEEE® 802.15.4-2011 RF connectivity for
portable, extremely low-power embedded systems. Applications include portable healthcare devices, wearable sports
and fitness devices, AV remote controls, computer keyboards and mice, gaming controllers, access control, security
systems, smart energy and home area networks.
The KW40Z MCU integrates a 2.4 GHz transceiver
supporting a range of FSK/GFSK and O-QPSK modulations, an Arm® Cortex®-M0+ CPU, 160
KB Flash and 20 KB SRAM, Bluetooth Low Energy Link Layer hardware, 802.15.4 packet processor, hardware security and
peripherals optimized to meet the requirements of the target applications. The KW40Z has enough on-chip memory to
concurrently run both a Bluetooth Low Energy stack and an IEEE 8021.5.4 MAC/PHY for multi-mode applications.
