Maxim Integrated's MAX32670 low-power microcontroller, based on the Arm Cortex-M4 core with floating-point processing, reduces power consumption and size while increasing reliability in industrial, biomedical, and Internet of Things (IoT) applications.
The device provides Error Correction Code ( ECC) protection of the embedded flash and SRAM memories, ensuring maximum microcontroller reliability.
In many industrial and IoT applications, high-energy particles and other environmental phenomena can alter the 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 catastrophic situations, the MAX32670 microcontroller protects all of its built-in memory (384 kB of flash and 128 kB of SRAM) with ECC coding, preventing random alteration of bits and improving reliability. Using ECC coding, single bit errors are detected and automatically corrected by the hardware, preventing them from having a negative impact on the application.
With a power consumption of only 40µW/MHz, the MAX32670 performs flash memory operations requiring up to 40% less power than the best competing solution on the market today.
MAX32670 is the lowest power consumption solution suitable for battery-powered sensor applications.
The MAX32670 is also 50% smaller than competing solutions, giving developers the opportunity to reduce application size and material costs.
Advantages
- Â High Reliability: ECC-protected flash and SRAM memories ensure the application will run for a long time, while secure boot and crypto hardware features increase reliability.
-  Reduced consumption: power consumption of only 40µW/MHz, 40% lower than competitors.
- Compact Size: 50% smaller footprint than competing solutions, available in ultra-thin 1.8 x 2.6 mm WLP and 5 x 5 mm TQFN packages.
Comments
"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."
