MG51 NuMicro® Microcontrollers (MCUs)

Nuvoton MG51 NuMicro^® Microcontrollers (MCUs) are embedded Flash type 1T 8051-based MCUs. These Microcontrollers support 16/24MHz core speed and are compatible with the 80C51 standard. The MG51 MCUs feature up to 32Kbytes of Flash memory, 256 bytes of RAM, 1 Kbyte of auxiliary RAM (XRAM), and, 4Kbytes of Flash loader memory (LDROM). These MCUs are equipped with two 16-bit timers, one 16-bit timer with three-channel input capture mode, one Watchdog timer, and six channels of PWM. The MG51 MCUs operate from a 2.4V to 5.5V voltage range and a -40°C to 105°C temperature range. These MCUs are ideal for home appliances, LED lighting controls, motor controls, and industrial automation applications.
