8051-based 1.8V low-power MCU
The NuMicro®ML51 series is a range of state-of-the-art, low-power, 1T 8051 core-based microcontrollers that function at a frequency of up to 24MHz. They operate using less than 80uA/MHz in normal runtime and drastically reduce power consumption when powered down to below 1uA. The ML51 serves a wide operating voltage that varies between 1.8V and 5.5V and operates at temperatures ranging from -40℃ to 105℃.
Function and Applications:
Developed by Nuvoton, the ML51 series is beneficial for applications that include smoke detectors, IoT sensor nodes, smart appliances, and data loggers. It provides more than a traditional 8-bit microcontroller, including powerful features such as a 12-bit 500k SPS ADC, comparators, and a Direct Memory Access (DMA) controller. With the availability of rich peripherals such as 2 sets of UART, 2 sets of ISO7816 interfaces,2 sets of I2C, and 2 sets of SPI, the ML51 series excels in efficiency and performance.
Operating with a 1T 8051-based CMOS microcontroller running up to 24 MHz, the ML51 offers up to 64 KB Flash and up to 4KB SRAM memory. It employs different power management strategies to optimize consumption, varying from normal run mode to power-down current modes. It also includes a 12-bit, 500k SPS SAR ADC, a PDMA controller, and up to 56 I/O with interrupt capability.
Package Types, Interface & Pin Configuration:
Supported packages for the ML51 series come in a wide variety, ranging from small form factor MSOP10, TSSOP14, QFN 20, TSSOP20, LQFP32, QFN33 up to LQFP 48-pin and LQFP64. Thus, the ML51 offers a versatile range of pin-compatible options for different system requirements.
