Nuvoton Technology M251ZD2AE
the M252 series are all based on the M251. It supports a crystal-less USB 2.0 full speed device that can generate precise frequency required by USB protocol without the need of external crystal to reduce the BOM cost and PCB size. The NuMicro® M251/M252 series integrates high performance analog front-end circuit blocks, such as 16 channels of 12-bit 730 kSPS ADC, 12-bit 1 MSPS DAC, analog comparator, operational amplifier, temperature sensor, low voltage reset (LVR) and brown-out detector (BOD) to enhance product performance, reduce external components and form factor simultaneously.

GENERAL DESCRIPTION
The NuMicro® M251/M252 series is a low-power microcontroller platform based on Arm® Cortex® M23 core for Armv8-M architecture. It runs up to 48 MHz with 32 ~ 256 Kbytes embedded Flash memory and 8 ~ 32 Kbytes embedded SRAM, 4 Kbytes Flash loader memory (LDROM) for InSystem Programming (ISP). The 32-bit low-power microcontrollers supports wide supply voltage from 1.75V ~ 5.5V and operating temperature range from -40℃ ~ +105℃. Low-power Technology for IoT application The NuMicro® M251/M252 series behaves low power consumption in Normal Run mode 138μA/MHz at 48MHz, 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. The NuMicro® M251/M252 series integrates RTC with independent VBAT voltage source pin to support low power mode with main power off and VBAT only. Its low power, wide supply voltage and fast wake-up features make it suitable for battery-powered IoT applications. Progr...
