Nuvoton – M2A23LD5AC: The new microcontroller is designed for industrial and automotive applications.

The NuMicro® M2A23LD5AC delivers high performance with the ability to operate in ambient temperatures up to 125°C and supports a wide operating voltage range from 2.5V to 5.5V. With up to three CAN FD interfaces, this product line is specifically designed to meet the stringent requirements of industrial and automotive applications.

Powered by an ARM® Cortex®-M23 core running at up to 72 MHz, the M2A23LD5AC integrates a Memory Protection Unit (MPU) and Nested Vectored Interrupt Controller (NVIC) to enhance security and task management.

Nuvoton’s M2A23LD5AC offers 64 KB of embedded Flash memory, 24 KB of SRAM, and 4 KB of loader Flash (LDROM) for In-System Programming (ISP). It supports multiple bootloader interfaces including CAN FD, SPI, UART, and I²C. Additionally, up to six PDMA channels enable efficient data transfers, offloading the CPU and ensuring smoother system performance.

The M2A23LD5AC features robust timing capabilities, including four 32-bit timers, twelve 144 MHz PWM outputs, and two watchdog timers. The 24-bit SysTick timer supports precise task scheduling, making it ideal for real-time applications.
