The Low Power MUG51 series offers good efficiency, versatility, and compactness in a flash-embedded microcontroller solution.

Nuvoton Technology has released a low-power MUG51 series, a family of flash embedded microcontrollers designed specifically for low-power applications. The MUG51 series offers high efficiency, rich set of peripherals, and compact form factor, making the MUG51 series suitable for battery-free devices, such as stylus pens powered by electro-magnetic Resonance (EMR) technology and RFID cards.

The company claims that the MUG51 series has been designed with an impressive low current consumption. These microcontrollers consume just 200 μA during CPU Power-on before Flash memory initialization, making them highly suitable for battery-free devices that draw power from the magnetic field of coils. Even during normal operation at 7.3728 MHz, the current consumption remains below 1.3 mA. In power-down mode, the microcontrollers consume less than 1 μA, ensuring optimal power efficiency

The Low Power MUG51 series offers a broad range of peripherals, enabling flexible and enhanced functionality. It boasts 24 general-purpose I/Os with internal inverters, four 16-bit Timers/Counters, UARTs with frame error detection and automatic address recognition, ISO7816 Smartcard interfaces, SPI interfaces, I²C interfaces, enhanced PWM output channels, analog comparators, pin interrupts, and more. With this extensive set of peripherals, users can achieve seamless connectivity with external devices, reduce the need for additional components, and enhance overall product performance.

Power Management and Wake-Up Capabilities
To optimize power management, the Low Power MUG51 series integrates Power-on Reset, Brown-out Reset, and Low voltage Reset functions. The microcontrollers consume only 1.08 mA in normal run mode and a mere 1 μA in Power-down mode. Moreover, they support wake-up from Power-down mode through various triggers, including ACMP, GPIO, WDT, TIMER, UART, I²C, SPI, PDMA, and PWM. This ensures efficient and responsive operation while effectively conserving power.

The Low Power MUG51 series offers good efficiency, versatility, and compactness in a flash embedded microcontroller solution. With its low current consumption, extensive set of peripherals, and flexible design, this series is an excellent choice for battery-free devices, including stylus pens powered by EMR technology and RFID cards. The Low Power MUG51 series provides a reliable and efficient solution for a wide range of applications, ensuring optimal performance and power management in demanding environments.
