Kinetis L series MCU families combine the latest low-power innovations with precision
mixed-signal capability and a broad range of communication, connectivity, and human-
machine interface peripherals. Each MCU family is supported by a market-leading
enablement bundle from Freescale and numerous ARM 3rd party ecosystem partners.
The KL0x family is the entry-point to the Kinetis L series and is pin compatible with the
8-bit S08PT family. The KL1x/2x/3x/4x families are compatible with each other and
their equivalent ARM Cortex-M4 Kinetis K series families - K10/20/30/40.

All Kinetis L series families include a powerful array of analog, communication and
timing and control peripherals with the level of feature integration increasing with flash
memory size and the pin count. Features within the Kinetis L series families include:
• Core and Architecture:
• ARM Cortex-M0+ Core running up to 48 MHz with zero wait state execution
from memories
• Single-cycle access to I/O: Up to 50 percent faster than standard I/O,
improves reaction time to external events allowing bit banging and software
protocol emulation
• Two-stage pipeline: Reduced number of cycles per instruction (CPI),
enabling faster branch instruction and ISR entry, and reducing power
consumption
• Excellent code density vs. 8-bit and 16-bit MCUs - reduces flash size,
system cost and power consumption
