Taiwanese microcontroller supplier Nuvoton Technology recently announced the launch of the MUG51 8-bit MCU series, a low-power microcontroller designed for battery-less devices.

Nuvoton has been committed to sustainable development by producing 8-bit MCUs, ensuring a stable supply and product lifespan, enabling customers to confidently commit to long-term products, platforms, and projects.

The new MUG51 series 8-bit low-power MCUs for battery-less devices combine a 1T 8051 core microcontroller operating at 7.37MHz with 16KB of on-chip flash APROM and 1KB of SRAM memory.

The MUG51 series supports specially designed power-on and resume functions. After power-on, it requires only 200 μA of startup current before flash memory initialization, and normal operation consumes less than 1.3 mA. In power saving mode, it uses less than 1μA.

To meet the needs of flexible application designs that minimize platform size and cost, the MUG51 series provides a diverse set of peripherals, including GPIO with internal inverter, 16-bit timer, 12-bit ADC, 16-bit PWM, UART, I2C, SPI, two rail-to-rail comparators (ACMP) for stylus pen pressure measurement, and an ISO 7816-3 smart card interface that can also be configured for UART transmission.

For applications exposed to harsh environments, it supports a wide operating voltage range of 1.8 to 5.5 V, a wide operating temperature range of -40°C to 105°C, and high resistance to electrostatic shock with EFT ±4.4 kV and ESD HBM ±7 kV.
