M251ZC2AE

M251_32KB

 

The NuMicro® M251ZC2AE 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® M251ZC2AE 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 1.5 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® M251ZC2AE integrates Voltage Adjustable Interface ( VAI ) , with 4 I/O pins to support the 2nd I/O voltage from 1.65 ~ 5.5 V to save level shifter components while connecting to external devices.

The NuMicro® M251ZC2AE 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® M251ZC2AE is equipped with plenty of peripherals such as Timers, Watchdog Timers, RTC, GPIOs x26, up to 12 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 M251ZC2AE integrates high performance analog front-end circuit blocks, such as 10 channels of 12-bit 840 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 M251ZC2AE is QFN33 ( 5 mm x 5 mm ). Pin-to-pin compatible in same package makes optimizing product features and performance easily.
