Nuvoton has recently introduced two new microcontrollers to its microcontroller lineup: the M463 CAN FD/USB HS Series and the M467 Ethernet/Crypto Series.
These microcontrollers are designed for application across diverse sectors, including IoT gateways, industrial control, telecoms, data centers, smart grid control, white goods motor control, small TFT LCDs, and TinyML (Machine Learning) products.
Both are 32-bit microcontrollers based on Arm Cortex-M4F core, up to 200 MHz, with DSP instruction set and single-precision floating-point unit (FPU).
The M463 focuses on CAN FD (Controller Area Network Flexible Data-Rate) applications, specifically for sensor and control data. In contrast, the M467 provides enhanced on-chip support for network communication and meets robust hardware cryptography requirements.
We are delighted to share that the M467 has recently been honored with the 2023 EE Awards Asia – Best MCU/Driver IC of the Year on December 6th, 2023.
