NXP Semiconductors Kinetis KL1x Microcontrollers

NXP Semiconductors Kinetis KL1x Microcontrollers, based on the Arm® Cortex®-M0+ core, combine ultra-low-power performance with a rich suite of analog, communication, timing, and control peripherals. Kinetis KL1x MCUs start from 32KB of flash in a small 3.5mm x 3.5mm XFBGA-32 package, extending up to 256KB in an LQFP-80 package. The NXP KL1x MCU family is compatible with the Cortex M4-based Kinetis K10 MCU family, offering a migration path to higher performance and feature integration.

Features

Ultra-Low-Power
- Next-generation 32-bit Arm Cortex-M0+ core: 2x more CoreMark/mA than the closest 8/16-bit architecture
- Single-cycle fast I/O access port facilitates bit banging and software protocol emulation, keeping an 8-bit "look and feel"
- Multiple flexible low-power modes, including new compute clocking option which reduces dynamic power by placing peripherals in an asynchronous stop mode
- LPUART, SPI, I²C, FlexIO, ADC, DAC, LP timer and DMA support low-power mode operation without waking up the core
Memory
- Up to 256KB flash with 64 byte flash cache, up to 32KB RAM
- Security circuitry to prevent unauthorized access to RAM and flash contents
- 16KB ROM and built-in boot loader simplifies the effort to program MCU and allows for easy flash upgrades
Performance
- Arm Cortex-M0+ core, 48MHz core frequency over full voltage and temperature range (-40ºC to +105ºC)
- Bit manipulation engine for improved bit handling of peripheral modules
- Thumb instruction set combines high code density with 32-bit performance
- Up to 4-channel DMA for peripheral and memory servicing with reduced CPU loading and faster system throughput
- Independent-clocked COP guards against clock skew or code runaway for fail-safe applications

Mixed-Signal
- Up to 16-bit ADC with configurable resolution, sample time and conversion speed/power
