The Kinetis® KL3x MCU family combines ultra-low power performance with a rich suite of analog, communication, timing, and control peripherals for consumer and industrial metering applications.
* Adds a segment LCD controller option to the Kinetis KL1x series
* Includes multiple, flexible low power modes including new compute mode that reduces dynamic power by placing peripherals in an asynchronous stop mode
* Provides a migration path to lower or higher performance and feature integration through compatibility with other Kinetis MCUs
* Backed by robust development tools and software

## 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, ADC, DAC, LP timer and DMA support low-power mode operation without waking up the core
### Memory
* Up to 256 KB flash with 64 byte flash cache, up to 32 KB RAM
* Security circuitry to prevent unauthorized access to RAM and flash contents
* 16 KB ROM and built-in boot loader simplifies the effort to program MCU and allows for easy flash upgrades
### Performance
* Arm® Cortex®-M0+ core, 48 MHz 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-ch. 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
* Integrated temperature sensor
* High-speed comparator with internal 6-bit DAC
* 12-bit DAC with DMA support
### Timing and Control
* Two 6-ch. and one 2-ch., 16-bit low-power timer PWM modules with DMA support
