overview the kinetis kl1x mcu family is pin, software and tool compatible with all other kinetis l families, and provides additional memory, communications and analog peripheral options beyond those offered on the kl0x family. the kinetis kl1x mcu family is also compatible with the kinetis k10 family of mcus built on the arm ? cortex tm -m4 core, 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 a 80 lqfp package. each family member combines ultra-low-power performance with a rich suite of analog, communication, timing and control peripherals. 32-bit l series mcus ultra-low-power, entry-level mcus kinetis kl1x family kinetis kl1x mcu family block diagram standard optional kinetis kl1x mcu family: block diagram hmi frequency- locked loop phase-locked loop low/high- frequency oscillators internal reference clocks 2x uart 2x spi i 2 s xtrinsic low-power touch-sensing interface gpio debug interfaces interrupt controller micro trace buffer 16 - bit adc pwm analog comparator 12 - bit dac program flash (32 to 256 kb) internal watchdog sram (4 to 32 kb) low-power uart arm ? cortex tm -m0+ core 48 mhz system memories clocks communication interfaces timers analog periodic interrupt timers low-power timer dma low-leakage wake-up unit unique id bit manipulation engine 2x i 2 c real-time clock target applications ? low-power applications ? battery-operated applications ? usb peripherals ? consumer applications
