Maximum power efficiency and system integrity is said to be achieved through decoupling of the application and real-time domains. Each domain has separate power, clocking and peripherals to deliver a heterogeneous architecture. The Cortex-M4 based real time domain handles low power operation and data consumption modes, while the Cortex-A7 based application domain is used for active modes.
* Meanwhile, NXP has also launched the Cortex-M4 based Kinetis K27/K28 family. Running at up to 150MHz, the MCUs come with up to 1Mbyte of embedded SRAM and up to 2Mbyte of flash.
“Embedded designers can now push the limits of integration to create more competitive products with the K27/K28 MCUs,” said Geoff Lees, general manager of NXP’s microcontroller business.
