MCU Presents Low Energy Consumption and Small Dimension for IoT Functions

Maxim Built-in’s new Arm Cortex-M4-based MCU offers dependable operation uninterrupted by bit flips
Additionally permits builders to supply a low-power resolution

Maxim Built-in has launched the MAX32670, a low-power Arm Cortex-M4 microcontroller (MCU) with floating-point unit. The machine protects all embedded reminiscence for each flash and SRAM with error-code correction (ECC) to supply the best reliability MCU, thus lowering the ability consumption and dimension whereas growing the reliability of business, healthcare and web of issues (IoT) functions.

In lots of industrial and IoT functions, excessive vitality particles and different environmental challenges current the hazard of bombarding reminiscence and creating bit flips throughout operation, particularly as course of nodes drop to 40nm and decrease. This will disrupt the MCU operation and produce incorrect and even harmful outcomes. To forestall such an occasion to occur, the MAX32670 protects an MCU’s complete reminiscence footprint (384kB flash and 128kB SRAM) with ECC to stop bit flips and improve reliability. With ECC, single-bit errors are detected and corrected by , making it troublesome for bit-flip errors to have a adverse impression on the applying.


With simply 40µW/MHz of lively energy consumption, the MAX32670 executes instructions from flash at 40 per cent low energy than different options. It’s the lowest energy resolution for battery-operated sensor functions. MAX32670 can be 50 per cent smaller, permitting builders to cut back resolution dimension and materials prices.


Excessive Reliability: ECC-protected flash and SRAM stop bit flips for greater uptime; safe boot and crypto improve reliability.
Lowest Energy: 40µW/MHz of lively energy consumption.
World’s Smallest: 50 per cent smaller footprint than opponents – is available in ultra-small 1.8mm-x-2.6mm WLP and 5mm-x-5mm TQFN.

 “Bit flipping turns into a vital reliability concern as microcontrollers scale all the way down to 40nm and under,” stated Kris Ardis, govt director, Micros, Safety and Software program Enterprise Unit at Maxim Built-in. “The MAX32670 is designed with a excessive diploma of safety towards these occasions so our prospects have the reliability they will belief as they prepared new methods in lengthy lifetime and mission-critical functions.”

The MAX32670 and the MAX32670EVKIT# is obtainable at Maxim Built-in’s web site and in addition from licensed distributors.
