NXP Semiconductors Kinetis K1x 32-bit Microcontrollers are pin-, peripheral-, and software-compatible MCUs based on the Arm® Cortex®-M4 core. Devices start from 32KB of flash in a small-footprint 5mm x 5mm QFN-32 package, extending up to 1MB in a MAPBGA-144 package. These scalable MCUs feature a rich suite of analog, communication, timing, and control peripherals. Additionally, flexible low-power capabilities, mixed-signal analog integration, and innovative FlexMemory (EEPROM) help to solve many of the major pain points for system implementation. High memory density K1x Devices include a single-precision floating-point unit and a NAND flash controller. The K12 MCUs are additional devices within the K1x family, offering lower power and higher memory densities in smaller packages. The K11 MCUs add Tamper functionality to the K12 Device. Within the NXP K11 and K12 families, devices range from 128KB to 512KB of flash memory. Package options include LQFP-48 up to MAPBGA-121.
