K27/K28 USB ARM® Cortex®-M4 MCUs

NXP's Kinetis K27 and K28 USB ARM Cortex-M4 MCUs for use in a variety of applications

Image of NXP's K27/K28 USB ARM Cortex-M4 MCUs The Kinetis K27 and K28 USB ARM Cortex-M4 MCUs expand NXP's Kinetis K MCU portfolio with extra-large embedded memory of 2 MB Flash and 1 MB SRAM. They target applications which require processing efficiency as well as tight integration.

Highly integrated with two I2S interfaces, two USB controllers (high-speed with integrated high-speed PHY and full-speed crystal-less) and mainstream analog peripherals, the Kinetis K27 and K28 are also expandable through a 32-bit SDRAM memory controller and QuadSPI interface supporting eXecution-In-Place (XiP).

Kinetis K27 and K28 MCUs enable secure content using a true random number generator, cyclic redundancy check, memory mapped cryptographic acceleration unit, and provide a strong foundation to support requirements for the next generation of Internet of Things (IoT) applications.
