Nuvoton MUG51 Low Power Microcontrollers

The Low Power MUG51 series is a Flash embedded 1T 8051-based low-power microcontroller. It runs up to 7.3728 MHz with 16 Kbytes embedded Flash memory, 1 Kbytes embedded SRAM, 4 Kbytes Flash loader memory (LDROM), 1.8V ~ 5.5V operating voltage, and -40°C ~105°C operating temperature.

 

The Low Power MUG51 series supports enhanced low current consumption at 200 μA while CPU Power-on before Flash memory is initialized. Its low-power feature makes it suitable for battery-free device which harvests power from the magnetic field of coil such as stylus pen powered by EMR (Electro-magnetic Resonance) technology and RFID card.

 

The Low Power MUG51 series features low current consumption at 200 μA while CPU Power-on before Flash memory is initialized. It is suitable for battery-free devices such as stylus pen powered by EMR (Electro-magnetic Resonance) technology and RFID card. The current consumption is less than 1.3 mA in normal run mode at 7.3728 MHz, and less than 1 μA in Power-down mode.

 

The Low Power MUG51 series provides rich peripherals including 24 general purpose I/Os with internal inverter, four 16-bit Timers/Counters, 2 sets of UARTs with frame error detection and automatic address recognition, 1 set of ISO7816 Smartcard interface, 1 set of SPI, 2 sets of I²C, 6 enhanced PWM output channels with dead zone control, 2 sets of analog comparators, eight-channel shared pin interrupt for all I/O ports, low voltage reset (LVR) and brown-out detector (BOD) to enhance product performance, reduce external components and form factor simultaneously.
