The NuMicro M254/M256/M258 series 32-bit low-power microcontroller is based on Arm Cortex-M23 core using Armv8-M architecture with COM/SEG LCD display driver and capacitive touch key functions; an USB 2.0 full speed device is also equipped to support the communication with PC/Mobile accessories. It runs up to 48 MHz and features up to 256 Kbytes Flash memory, up to 32 Kbytets SRAM, 1.75V ~ 5.5V wide operating voltage, 5V I/O tolerance, and -40℃ to +105℃ operating temperature.

The M254/M256/M258 series provides low power consumption in Normal Run mode 110 μA/MHz at 48 MHz, Power-down mode with 3.8 μA while RTC on and RAM retention, and it can supports down to 2.2uA while RTC off, and Deep Power-down mode is down to 1.6 μA. The M254/M256/M258 series integrates RTC with independent VBAT voltage source pin to support low power mode with main power off and VBAT only.

An 8 x 44, 6 x 46, 4 x 48 COM/SEG LCD is available on the M254/M256/M258 series. The COM/SEG LCD driver with selectable bias voltage and duty, and it also built-in charge-pump to support 3V to 5V wide voltage of LCD panel; Capacitive touch sensing function with up to 24 touch-keys with single-scan or programmable periodic key-scans is supported by M256/M258 series; The M258 series supports a crystal-less USB 2.0 full speed device, compling with USB Battery Charging Detection v1.2 (BC 1.2) profile for high-speed battery charging. 

The M254/M256/M258 series is equipped with plenty of peripherals such as Timers, Watchdog Timers, RTC, up to 8 channels of PDMA, 4 sets of UART, 2 sets of Universal Serial Control Interface (USCI), 2 sets of SPI/ I²S, 2 sets of I²C, 1 set of ISO-7816-3, up to 12 channels of basic PWM, making it highly suitable for connecting comprehensive external modules. It also integrates high performance analog circuit, such as 16 channels of 12-bit 730 kSPS ADC, up to 2 sets of 12-bit 1 MSPS DAC, and a temperature sensor to reduce external components. 

Supported packages include LQFP44, LQFP64 and LQFP128, those are pin-compatible to M251/M252, M031 and M480 series to make the system design and parts change on functional enhancement easily.
