Nuvoton Technology has launched its new NuMicro M3351 series of 32-bit microcontrollers. These devices are designed to operate at clock speeds reaching 144 MHz.
Why it matters
The series includes support for input voltages ranging from 2.7V to 5.5V, allowing for seamless integration into industrial systems that rely on higher-voltage logic. This versatility improves the efficiency of sensing and feedback operations within embedded architectures.
The NuMicro M3351 series features an Arm Cortex-M33 core with 256 KB to 1 MB of Flash memory and up to 128 KB of SRAM. It supports a 12-bit SAR ADC at 1.7 MSPS and a 14-bit SAR ADC at 1.0 MSPS across a temperature range of -40°C to +105°C.
The players
Nuvoton Technology
Nuvoton Technology is a semiconductor manufacturer that specializes in microcontrollers, audio components, and power management solutions.
The details
The microcontrollers manage peripheral events through hardware trigger paths, which bypasses the CPU to increase processing efficiency. Connectivity options are broad, encompassing CAN FD, UART, I²C, I3C, and USB, with selected models supporting firmware-over-the-air updates.
Timeline
The NuMicro M3351 series was launched on September 22, 2026.
The Tech Race
This release positions Nuvoton Technology within the highly competitive market for secure, high-performance embedded systems built on the Arm Cortex-M33 core. It represents a shift toward more integrated analogue capabilities in 32-bit controllers, replacing legacy designs that require external sensing hardware.
Engineers and developers can now utilize these chips to design systems that handle wider voltage ranges without additional power conversion hardware. The integrated ADC peripherals may also simplify the development of feedback loops in consumer and industrial devices.
The takeaway
Designers should evaluate whether the 5V operational range of these chips simplifies their existing circuit board power requirements. Leveraging integrated hardware trigger paths can also help reduce CPU load in time-sensitive sensing applications.
