32-bit L Series MCUs Kinetis KL1x Family Ultra-low-power, entry-level MCUs Target Applications Overview • Low-power applications 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® CortexTM-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. • Battery-operated applications • USB peripherals • Consumer applications Kinetis KL1x Block Diagram Kinetis KL1x MCUMCU Family:Family Block Diagram ARM® CortexTM-M0+ Core System Memories Program Flash (32 to 256 KB) Clocks Phase-Locked Loop Debug Interfaces Internal Watchdog Interrupt Controller DMA FrequencyLocked Loop Micro Trace Buffer Low-Leakage Wake-Up Unit Low/HighFrequency Oscillators Bit Manipulation Engine 48 MHz Analog 16-bit ADC Analog Comparator 12-bit DAC Standard SRAM (4 to 32 KB) Internal Reference Clocks Unique ID Timers PWM Periodic Interrupt Timers Communication Interfaces HMI 2x I2C GPIO Low-Power UART Xtrinsic Low-Power Touch-Sensing Interface 2x UART Low-Power Timer 2x SPI Real-Time Clock I2S Optional Features Ultra Low Power • Next-generation 32-bit ARM Cortex-M0+ core.
