With low power technology, Nuvoton ML51 series is based on 1T 8051 core microcontroller to support power down current below 1 μA, power consumption is 80 μA/MHz in normal run mode. It provides operating frequency up to 24 MHz, operating voltage from 1.8V to 5.5V and operating temperature -40℃ ~105℃. 
ML51 series is more than a 8-bit microcontroller, which equipped with several powerful features, such as 12-bit ADC, comparators, internal voltage reference, and Direct Memory Access(DMA) controller; ML51 also provides rich peripherals such as 2 sets of UART; 2 sets of smart card interface; 2 sets of I?C, and 2 sets of SPI. 
ML51 series is a complete MCU application platform with flash size from 16 KB to 64 KB, SRAM size from 1 KB to 4 KB. Packages are from small form factor MSOP10, TSSOP14, QFN 20, TSSOP20, LQFP32, QFN33 to LQFP 48-pin and LQFP64. Different part number with same package is supported Pin to Pin compatible, it makes users to select different flash memory size chip and change easily.
