Nuvoton Expertise has introduced a brand new energy-efficient microcontroller, the M2L31, based mostly on Arm’s Cortex-M23 core — and that includes as much as 512kB of high-performance low-power non-volatile resistive RAM (ReRAM).
“In an period the place vitality effectivity is paramount,” the corporate says in assist of its newest chip design, “Nuvoton Expertise is proud to announce the launch of its new Arm Cortex-M23 M2L31 microcontroller collection. Designed to fulfill the rising demand for sustainable high-performance embedded computing energy, the M2L31 collection stands out for its low energy consumption and effectivity, with its working pace of as much as 72MHz nonetheless offering nice processing functionality.”
That low energy consumption is, based on the corporate’s inside testing, as little as 60μA/MHz in regular working circumstances — and dropping down to simply 0.5μA within the half’s lowest-power “deep shutdown” mode. A part of this effectivity comes from Nuvoton’s choice to change from conventional flash reminiscence to on-chip resistive RAM (ReRAM), another non-volatile storage expertise that attracts much less energy and could be written to with out an erase cycle beforehand.
The launch comes two months after the corporate unveiled the NuMicro MA35D0, a twin Arm Cortex-A35 design working at as much as 650MHz. Whereas that specific mannequin focused what the corporate described as “industrial edge machine purposes,” its M2L31 is designed for initiatives that require a steadiness of efficiency and energy — and which do not want a full Linux-capable microprocessor or megabytes of RAM.

Precise specs for the M2L31 rely upon the mannequin chosen, with configurations accessible providing between 40kB and 168kB of static RAM and between 64kB and 512kB of ReRAM. All fashions could be clocked at as much as 72MHz, whereas peripherals embrace two USB 3.0 Kind-C Energy Supply (PD) ports, two CAN FD buses, and as much as eight UART, 4 I2C, and 4 shared SPI and I2S buses, plus as much as 16 channels of capacitive contact sensing, a 24-channel 12-bit analog to digital converter (ADC), as much as two 12-bit digital to analog converters (DACs).
Extra data on the M2L31 household is obtainable on the Nuvoton web site. Nuvoton has additionally confirmed a quick-start analysis board, the M2L31 NuMaker, for these trying to experiment with the chips. Pricing and availability had not been introduced on the time of writing.
