ML51 NuMicro Microcontrollers (MCUs)

Nuvoton ML51 NuMicro Microcontrollers (MCUs) are 1T 8051 core based low-power MCUs running up to 24MHz speed with less than 80μA/MHz in normal run mode. These three-in-one single MCUs offer three power modes (low power run mode, low power idle mode, and power-down mode) to reduce power consumption. The ML51 MCUs provide low-power run mode at a low-frequency clock source selectable by a 38.4kHz internal clock or external 32.768kHz crystal. These MCUs include peripherals such as two sets of UART, two sets of ISO7816 interfaces, two sets of I²C, and two sets of SPI. The ML51 MCUs support 16KB to 64KB Flash size, 1KB to 4KB SRAM size, and up to 4KB Flash for user program loader (LDROM) share with ARPOM.
