NXP Kinetis K27/K28 MCU Families power-efficient dual-USB

The Kinetis K27 and K28 with ARM® Cortex®-M4 expand NXP’s Kinetis K portfolio with embedded memory of 2 MB Flash and 1 MB SRAM

The Kinetis K27 and K28 with ARM® Cortex®-M4 expand NXP’s Kinetis K portfolio with embedded memory of 2 MB Flash and 1 MB SRAM, targeting applications which require processing efficiency as well as tight integration.

Highly integrated with two I2S interfaces, two USB Controllers and analog peripherals, they are expandable through a 32-bit SDRAM memory controller and QuadSPI interface supporting eXecution-In-Place (XiP).

These MCUs enable secure content with TRNG, CRC, Memory Mapped Cryptographic Acceleration Unit, providing a strong foundation for the next generation of Internet of Things.
