In many industrial and IoT applications, high-energy particles and other environmental phenomena can alter memory content by changing the content of individual bits during normal operation, especially when using fabrication processes at 40 nm or less. This can cause the MCU to stop working properly and produce incorrect or even harmful results. To prevent such situations, Maxim Integrated offers the MAX32670 low-power microcontroller (MCU).

Based on the Arm® Cortex®-M4 core with a floating point calculation unit, the MAX32670 microcontroller protects all the embedded memory (384 kB flash and 128 kB SRAM) with ECC coding, preventing random bit alteration and improving reliability.

Maxim's solution reduces power consumption: with a power consumption of only 40µW/MHz, the MAX32670 performs flash memory operations requiring up to 40 percent less power than the best competing solution on the market today. It is also 50 per cent smaller than competing solutions, giving developers the opportunity to reduce application size and material costs.

"Accidental bit tampering has become a fundamental reliability issue for microcontrollers manufactured with electronic technology at 40 nm or lower," said Kris Ardis, executive director of Maxim Integrated's Micros, Security and Software Business Unit. "The MAX32670 is designed to provide a high degree of protection against these types of events, giving our customers the reliability required by long-life, mission-critical applications."
