Freescale Semiconductor has added a wireless, multi-protocol to its Kinetis microcontroller (MCU) family with support for Bluetooth Smart/Bluetooth Low Energy (BLE) and IEEE 802.15.4 applications.
The KW40Z wireless MCU integrates a 2.4 GHz multi-protocol radio that provides the ability to access one BLE network and one 802.15.4 network from a single device while achieving strong RF performance and low current consumption.
The radio runs in receive mode at 6.5mA with excellent co-existence characteristics, and provides years of operation on standard coin cell batteries.
An integrated DC/DC converter configurable for buck or boost operation optimises power consumption, and the MCU also incorporates a high precision DAC and a 16-bit ADC for highly accurate sensor measurement for wireless sensor networks.
Design support includes a royalty-free Freescale BLE host stack with 20 GATT profiles and is fully compliant to the BLE 4.1 specification.
The BLE stack is planned to support the upcoming Bluetooth Smart Mesh networking protocol.
The KW40Z MCU family also includes an 802.15.4 MAC layer as the foundation for ZigBee 3.0 and the highly anticipated Thread IP-based mesh networking protocol.
All stacks support over-the-air firmware updates and are fully integrated into the Kinetis software development kit (SDK) with support for multiple RTOS options, including FreeRTOS and Freescale MQX.
