MCX A17: Essential Arm® Cortex® M33 MCU with 180 MHz and Rich Serial Peripherals
Compact List
MCX C15 and MCX C16 Entry-Level, Low-Cost MCUs with Arm® Cortex®-M23 and Advanced Peripherals
- This page contains information on a preproduction product. Specifications and information herein are subject to change without notice. For additional information contact support or your sales representative.
The MCX C15 and MCX C16 microcontrollers (MCUs) are low‑cost, entry‑level devices featuring an Arm® Cortex®‑M23 core running at up to 72 MHz, with memory configurations offering up to 64 KB of flash memory and 16 KB of SRAM. These devices bring precision analog and control peripherals into the low‑cost, entry‑level MCU class, making advanced features—such as a 16‑bit analog‑to‑digital converter (ADC), comparator with digital‑to‑analog converter (DAC) and flexible pulse‑width modulation (FlexPWM) for motor control—accessible to cost‑sensitive IoT applications.
Designed as an upgrade path from legacy 8‑bit and 16‑bit MCUs, as well as devices based on Arm Cortex‑M0+ cores, this entry‑level 32‑bit MCU series delivers higher performance and greater scalability without increasing costs. Simple migration paths from widely used LPC800, LPC1100 and Kinetis MCUs—along with pin‑to‑pin compatible options within the newer MCX A Series—enable a seamless transition across the NXP MCU portfolio.
