NuMicro®ML51 series is 1T 8051 core based low-power microcontrollers running up to 24MHz with less than 80µA/MHz in normal run mode, and power down current is below 1uA. It provides another low power run mode at low frequncy clock source selectable by 38.4kHz internal clock or external 32.768kHz external crystal, The ML51 series provides wide operating voltage from 1.8V to 5.5V and operating temperature -40°C to 105°C. 

The features of NuMicro® ML51 series is more than a traditional 8-bit microcontroller, which equipped with several powerful features, such as 12-bit 500k SPS ADC, up to 2ch of comparators , 4-level of internal voltage reference for ADC and ACMP, and a Direct Memory Access(DMA) controller to speed-up the data transfer and off-load the CPU loading for low-power operation; the ML51 series also provides rich peripherals such as 2 sets of UART, 2 sets of ISO7816 interfaces,2 sets of I²C, and 2 sets of SPI. 

NuMicro® ML51 series provides flash size from 16KB to 64KB, SRAM size from 1KB to 4KB. Supported packages from small form factor MSOP10, TSSOP14, QFN 20, TSSOP20, LQFP32, QFN33 to LQFP 48-pin and LQFP64 with downward pin-compatible for different part numbers make the system design and change parts for the different system requirement easily.
