In many industrial and IOT applications, high-energy particles or other harsh conditions will destroy the memory during normal operation, resulting in its bit flip (especially when the semiconductor process drops to 40 nm, even lower). Thereby interrupt MCU work and generate errors or even dangerous results. To prevent such catastrophic consequences, the MAX32670 uses ECC to protect its entire memory space (384KB flash memory and 128kb SRAM) to reverse the turnover, which greatly enhances reliability. With ECC, hardware can detect and correct bit errors, avoiding the adverse effects of bit flip errors on practical applications.

The MAX32670 can perform a flash command with 40μW / MHz power consumption, and the power consumption is reduced by 40% compared to the closest competition scheme. Provide lowest power consumption for battery-powered sensor applications. In addition, the size of the MAX32670 reduces the size of 50% compared to the closest competition scheme, helping the developers reduce the size and material cost of the program.

Main advantage

· High reliability: ECC protection flash memory and SRAM, prevent bit flipping, improve system normal operation time; security boot and encrypt hardware enhancement reliability.

· Minimum power consumption: The power consumption of only 40μW / MHz is only 40% lower than the competition scheme.

• Minimum size: Scheme size is reduced by 50% higher than competitive solution - off-small size, 1.8mm-x-2.6mm WLP package and 5MM-X-5mm TQFN package.

Evaluation

· "With the microcontroller process drops to 40 nm or even lower, the bit flip has a key indicator affecting system reliability." Maxim Integrated Microprocessor and Kris Ardis, Executive Director of the Security Products Division, said: "The design of MAX32670 is for the above security Question provides powerful protection capabilities, providing our customers with high reliability and trustworthiness programs in new system designs that require long-term implementation of key tasks.
