Got a Battery-Operated Application, No Problem
Based on the Arm Cortex-M0+ core, the K32 L2 MCU family delivers a unique balance of low-power/low-leakage design with numerous standby and stop low-power modes; memory scalability going from 64KB to 512KB of Flash memory and a high precision mixed-signal integration featuring a high-resolution 16-bit ADC with single and differential pair input mode options and a 12-bit DAC with DMA support to offload the core and leave it available to perform other important tasks.
The K32 L2 MCU family is complemented by a set of low-power serial peripherals supporting asynchronous operation in low power modes, SPI interfaces, I2C, USB full-speed 2.0 supporting crystal-less operation and NXP’s proprietary FlexIO module supporting emulation of additional UART, SPI, I2C, PWM and other serial modules.
The K32 L2B family, which will be available mid-November 2019, features an energy efficient Cortex-M0+ running up to 48MHz, and a rich suite of timers, analog and communication interfaces with options of scaling from 64KB to 256KB of flash memory. Additional features, such as a segment LCD interface supporting up to 24x8 or 28x4 segments have been integrated to address different applications in the consumer, IoT and industrial spaces.

The K32L2A MCU family, coming January 2020, will feature a high-speed Arm Cortex-M0+ running up to 72MHz, flash memory options scaling from 256KB to 512KB and 128KB of SRAM. Key differentiating items include a low-power hardware touch sensing interface, 16-bit ADC with 24-cannels and a cryptographic acceleration unit supporting different algorithms such as DES, 3DES, AES, MD5, SHA-1 and SHA-256.

Efficient and General Purpose for a Range of Smart Home and Industrial IoT Applications
With a wide range of memory and performance scalability going from 64KB to 512KB and 48 to 72MHz of CPU speed, the K32 L2 MCU family can fit a wide range of applications, such as small appliances, smart/e-locks, handheld meters, electronic scales, lighting control, etc. If you want to leverage the numerous options of low power modes in an application where your system will be dormant for most of the time, waiting for an interruption to power up the device, you can leverage the sub 200nA leakage in stop mode or below 2uA sleep mode with instantaneous wake-up times to get your system up and running in a fast way. These features, along with the wide packaging options going from 5x5mm QFN32 to 14x14mm LQFP100 allows for easy project migration leveraging a common architecture and software framework.
Accelerate Your Time to Market
The entire K32 L2 MCU family is supported by NXP’s MCUXpresso software and tools bringing together the best of NXP’s software enablement by providing free and easy-to-use integrated development environment (IDE), an open source software development kit (SDK) with examples created specifically for the MCU of your choice and a comprehensive suite of system configuration tools that include pins, clocks and peripherals. On top of that, the K32 L2 MCU family will also be supported by the major toolchains including IAR Embedded Workbench IDE and Arm’s Keil Microcontroller Development Kit.
For easy prototyping and evaluation of the K32 L2 MCU family, hardware development kits will be available for each of the sub-families. The K32 L2B MCUs will be supported by the low-cost FRDM-K32L2B3 development platform. A getting started guide, a set of demos and examples will be available at launch to help you kick-off your design and accelerate your time to production.
