Our 32-bit microcontrollers provide the cornerstone for building robust devices in the Internet of Things (IoT) age. Ultra-low power operation helps maximize battery life, small footprints enable ubiquitous use, and best-in-class security protects your investment.

Our ultra-low-power, 32-bit microcontroller devices combine the biggest embedded memories of any MCUs in their class with ultra-efficient power management. Our extensive range of highly integrated Arm® microcontrollers are designed to provide maximum performance with minimal power consumption. Features include a modular arithmetic accelerator (MAA) with a hardware entropy source for advanced security, a dual-core MCU option with ample processing power for high-performance multitasking, and integrated BLE 5.0 allowing interconnection of devices on one chip.

Our secure 32-bit microcontrollers integrate advanced cryptography and physical security to provide the highest level of protection against side-channel attacks, physical tampering, and reverse engineering. Features include integrated secure nvSRAM memory that is instantly erased when an intrusion is detected and patented real-time data encryption that ensures external memory is fully protected. MCUs are available in a range of package/pin types conforming to EMV, PCI, and FIPS standards.

ChipDNA-generated keys derived from a physically unclonable function (PUF) provide an unprecedented level of protection against sophisticated invasive attacks, meaning our ChipDNA™ PUF technology delivers the highest level of IoT security.
