32-bit Microcontrollers
Kinetis K1x MCU Family
Low-power, mixed-signal MCUs
Target Applications
Overview
• Electronic point of sales (EPOS)
The Kinetis MCU portfolio consists of multiple pin-, peripheral- and software-compatible MCU
families based on the ARM® Cortex®-M4 core. Families are built from innovative 90 nm thin-film
storage (TFS) flash technology with unique FlexMemory (EEPROM) capability, and offer industryleading low power and mixed signal analog integration.
• Flow meters
• Gaming controllers
• HVAC systems
• Remote sensors
The K1x MCU family is the entry point into the Kinetis MCU portfolio. Devices start from 32 KB
of flash in a small-footprint 5x5 mm 32 QFN package, extending up to 1 MB in a 144 MAPBGA
package with a rich suite of analog, communication, timing and control peripherals. Additionally,
pin compatibility, flexible low-power capabilities and innovative FlexMemory help to solve many of
the major pain points for system implementation.
