On October 11th, NXP Semiconductors announced the first K32 L-series MCUs worldwide - the K32 L3 MCU series. After this release, NXP will soon launch the second line of this product line – the K32 L2 MCU family that optimizes cost and power. Based on the Arm® Cortex®-M0+, this new MCU family targets power-sensitive end nodes for a wide range of general-purpose industrial and Internet of Things (IoT) applications.

The dynamic power consumption of the K32 L2 MCU is 20% higher than the earlier KL series, using high-precision mixed-signal integration, including a configurable 16-bit ADC with a single differential input mode, a DMA addressable 12-bit DAC, and a high-precision internal reference ( 1.2V), and a high-speed comparator with an additional 6-bit DAC. The series' maximum frequency is up to 72MHz and can also be limited to 48MHz low power operation. A variety of standby and stop modes enable developers to achieve leakage currents below 200nA in stop mode and below 2uA in standby mode, and can wake up instantaneously within 8us.

Common features of the family include crystal-free full-speed USB operation, NXP's proprietary FlexIO for flexible expansion, and a wide range of energy-efficient optimized serial peripherals that can operate autonomously in low-power modes. Differentiated features include sector LCD drivers, cryptographic acceleration units supporting DES, 3DES, AES, MD5, SHA-1, and SHA-256 algorithms, hardware-accelerated true random number generators, and capacitive models supporting up to 16 external electrodes Touch sensing interface.

The K32 L2 family offers a scalable package and memory configuration from 64KB to 512KB of flash memory, supported by MCUXpresso software and tools, and demonstration projects using JAR, Keil and GCC-based toolchains. NXP's complementary kit ensures users No worries. Configuration tools from MCUXpresso for clocks, pins and peripherals, and fully integrated support for SEGGER and P&E Micro probes simplify development from prototyping to production.
