Nuvoton M483 NuMicro® CAN Series Microcontrollers (MCUs)

Nuvoton M483 NuMicro® CAN Series Microcontrollers (MCUs) are low-power and high-performance MCUs embedded with up to 192MHz Arm® Cortex®-M4F core delivering 1.25DMIPS per MHz. These MCUs feature 256KB zero-wait state Flash that supports eXecute-Only-Memory (XOM) and 128KB embedded SRAM that provides multi-level retention in standby power-down mode. The M483 MCUs are integrated with two or three sets of CAN 2.0B interface, dual 12-bit 5MSPS ADC, and a camera interface. These MCUs operate from 1.8V to 3.6V voltage range and -40°C to 105°C temperature range. The M483 MCUs are compliant with IEC-60730 Class B standards. These MCUs are used in motor control, industrial control, Battery Management Systems (BMSs), and EV charging pile applications.
