DATASHEET

The NuMicro® M251FC2AE is a low-power microcontroller based on Arm® Cortex®-M23 core for Armv8-M architecture. It runs up to 48 MHz with 32 Kbytes embedded Flash memory and 8 Kbytes embedded SRAM , 4 Kbytes Flash loader memory ( LDROM ) for In-System Programming ( ISP ) , The 32-bit low-power microcontrollers supports wide supply voltage from 1.8 ~ 5.5 V and operating temperature range from - 40 ℃ ~ + 105 ℃ .

The NuMicro® M251FC2AE behaves low power consumption in Normal Run mode 138 μA / MHz at 48 MHz , Idle mode 60 μA / MHz , power down mode 2.5 μA ( RTC on, RAM retention ) , power down mode 1.7 μA ( RTC off, RAM retention ) and Deep Power-down mode. It’s low power, wide supply voltage and fast wake-up features make it suitable for battery-powered IoT applications.

The NuMicro® M251FC2AE series provides 1-region programable eXecute-Only-Memory ( XOM ) to secure critical program codes. Accompany with 96-bit Unique Identification ( UID ) and 128-bit Unique Customer Identification ( UCID ) to enhance the product security.

The NuMicro® M251FC2AE is equipped with plenty of peripherals such as Timers, Watchdog Timers, RTC, GPIOs x15, up to 9 channels of PWM, Universal Serial Control Interface (USCI) x1, UART x2, QSPI x1, I²C x2, ISO-7816-3 x1, PDMA x5, makes it highly suitable for connecting comprehensive external modules and LED lighting control. The M251FC2AE integrates high performance analog front-end circuit blocks, such as 7 channels of 12-bit 880 kSPS ADC, temperature sensor, low voltage reset ( LVR ) and brown-out detector ( BOD ) to enhance product performance, reduce external components and form factor simultaneously.

The package types of the M251FC2AE is TSSOP20 ( 4.4 mm x 6.5 mm ). Pin-to-pin compatible in same package makes optimizing product features and performance easily.
