Freescale Kinetis L Series Built on the
ARM ^® Cortex™-M0+ Processor

Freescale's Kinetis KL0 family is the entry point into the Kinetis L Series MCUs based on the ARM® Cortex™-M0+ processor. Pin compatible with our 8-bit S08P family, the Kinetis KL0 family provides a bridge for 8-bit customers migrating into the Kinetis portfolio and is software and tool compatible with all other Kinetis L families. Devices start from 8 KB of flash in a small-footprint 4 x 4 mm 24 QFN package extending up to 32 KB in a 48 LQFP package. Each combines ultra-low-power performance with a rich suite of analog, communication, timing and control peripherals.

Freescale introduces the Kinetis KL02 chip-scale package (CSP), the world's smallest ARM Powered® MCU. Available in the ultra-small 1.9 mm x 2.0 mm wafer level chip-scale package, the KL02 CSP (MKL02Z32CAF4R) drastically reduces board space while retaining rich MCU feature integration. The KL02 CSP consumes 25 percent less PCB area, yet delivers 60 percent more GPIO than the nearest competing MCU. The Kinetis KL0 family is the entry point into the low-power Kinetis L series MCUs based on the ARM® Cortex™-M0+ processor, delivering 32-bit performance with class-leading code density, integrated flash memory, precision analog, connectivity and timers.

Freescale's Kinetis KL1 MCU family is pin, software and tool compatible with all other Kinetis L MCU families and provides additional memory, communications and analog peripheral options beyond those offered in the Kinetis KL0 MCU family. The Kinetis KL1 MCU family is also compatible with the Kinetis K10 MCU family (based on the ARM® Cortex™-M4 processor), providing a migration path to higher performance and feature integration. Devices start from 32 KB of flash in a small-footprint 5 x 5 mm 32 QFN package extending up to 256 KB in an 80 LQFP package. Each combines ultra-low-power performance with a rich suite of analog, communication, timing and control peripherals.
