Kinetis L series MCU families combine the latest low-power innovations with precisionmixed-signal capability and a broad range of communication, connectivity, and human-machine interface peripherals. Each MCU family is supported by a market-leadingenablement 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 the8-bit S08PT family. The KL1x/2x/3x/4x families are compatible with each other andtheir equivalent ARM Cortex-M4 Kinetis K series families - K10/20/30/40.KL2x FamilyKL1x FamilyKL0x FamilyKL3x FamilyFamily ProgramFlash Packages Key FeaturesLow power Mixed signal USB Segment LCDKL4x Family8-32KB32-256KB32-256KB64-256KB128-256KB16-48pin32-80pin32-121pin64-121pin64-121pinFigure 2-1. Kinetis L series families of MCU portfolioAll Kinetis L series families include a powerful array of analog, communication andtiming and control peripherals with the level of feature integration increasing with flashmemory 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 executionfrom 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 softwareprotocol emulation• Two-stage pipeline: Reduced number of cycles per instruction (CPI),enabling faster branch instruction and ISR entry, and reducing powerconsumption• Excellent code density vs. 8-bit and 16-bit MCUs - reduces flash size,system cost and power consumptionKinetis L SeriesKL25 Sub-Family Reference Manual, Rev. 3, September 201236 Freescale Semiconductor, Inc.
