Nuvoton is committed to sustainable 8-bit MCU production and product longevity to ensure a reliable supply, the aim being to give its customers the confidence to commit to long-term products, platforms, and projects.
The low power MUG51 series incorporates an 1T 8051 core microcontroller operating at 7.37 MHz, plus 16 KB Flash APROM and 1 KB SRAM memory within the chip. The MUG51 series supports special design power-on and resume, requiring a start-up current of just 200 μA after power-on and before Flash memory initialisation, while a normal operating mode uses less than 1.3 mA. In sleep-mode, it uses less than 1 μA.
To meet flexible application design demands that minimise platform size and cost, the MUG51 series provides a rich set of peripherals including GPIO with an internal inverter, 16-bit timers, 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 can also configure as UART transmission.
For applications that experience extreme conditions it supports a wide operating voltage range of 1.8-5.5V, and wide operating temperature of - 40°C to 105°C, plus high resistance to electrostatic shock with EFT ±4.4 kV and ESD HBM ±7 kV.
