32-bit Arm Cortex-M MCU

32-bit Arm Cortex-M MCU and Arm9 MPU

Our components and custom solutions

Atlantik Elektronik offers a large portfolio of more than 600 types of microcontrollers, using the industry-standard Arm Cortex-M architecture. 

It includes power-efficient 32-bit Arm Cortex-M0 MCU up to high-performance Cortex-M4F with FPU and clock speed of nearly 200Mhz. For industrial applications, our MCUs support temperatures up to 105 degrees celsius and have a noise immunity of 8kV ESD (electrostatic discharge).

We also have Arm9-based products with integrated DRAM memory, a compact System on Chip (SoC) solution that saves PCB space and design time. Additionally, we have products with the latest Cortex-M23, combined with Armv8 architecture and TrustZone technology that aims to provide security to IoT products.
