Kinetis® K27-150 MHz, 2x USB, 2MB Flash, 1MB SRAM Microcontrollers (MCUs) based on Arm® Cortex®-M4 Core

K27_150

The Kinetis K27 USB Arm® Cortex®-M4 MCUs target applications requiring processing efficiency and extra-large embedded memory with 2 MB Flash and 1 MB SRAM. This sub-family is:

  • Highly integrated with two I2S interfaces, two USB Controllers (High-Speed with integrated High-Speed PHY and Full-Speed) and mainstream analog peripherals
  • Expandable through a 32-bit SDRAM memory controller and QuadSPI interface supporting eXecution-In-Place (XiP)
  • Enabling secure content using a True Random Number Generator, Cyclic Redundancy Check, Memory Mapped Cryptographic Acceleration Unit

Input supply voltage: 1.71V to 3.6V + separate VBAT domain

Packages: 169 MAPBGA (9x9mm, 0.65mm pitch)

Evaluation / Development platform: FRDM-K28F
