Nuvoton’s M2L32 MCUs are powered by a 72-MHz Arm Cortex-M23 processor core with up to 512 kbytes of resistive random-access memory (ReRAM). This nonvolatile memory delivers fast read/write speeds and endures significantly more program/erase cycles than flash memory. Additionally, ReRAM consumes less power than both DRAM and flash.
Aimed at sustainable embedded computing, the M2L32 series of microcontrollers offers three low-power modes: normal shutdown, standby shutdown, and deep shutdown. Typical current consumption is just 60 µA/MHz in operating mode, dropping to 0.5 µA in deep shutdown mode.
M2L32 MCUs can be used for motor control, battery management, industrial automation, and PC peripheral devices. These MCUs independently handle peripheral data acquisition and process data through low-power serial interfaces without CPU intervention.
Along with 64 kbytes to 512 kbytes of ReRAM, the M2L31 series provides 40 kbytes to 168 kbytes of SRAM and a rich set of communication interfaces and peripherals. Devices are offered in a variety of package types and sizes, including WLCSP, QFN, and LQFP.
