Chipsets embedded in products operating in external environments must maintain a wide operating temperature range to ensure stable and reliable operation. Nuvoton has therefore unveiled a next-generation MCU series with an expanded operating temperature range.

Nuvoton Technology unveiled its next-generation high-performance NuMicro M463 MCU series on the 26th (local time).

This series features a 200MHz Arm Cortex-M4 processor and an extended operating temperature range of -40°C to 125°C, emphasizing its ability to meet stringent high-temperature environmental requirements and ensure stable operation even under extreme conditions.

In addition to a wide temperature range, Nuvoton said it offers various peripheral interfaces, including dual CAN-FD and HS USB communication functions, 256KB programmable memory, and 128KB SRAM, providing an efficient solution for automotive electronics and industrial applications.

Additionally, the NuMicro M463 series achieves ultra-low power consumption of less than 200nA. It supports a variety of power operation modes and wake-up interfaces to meet diverse power and customer requirements. Featuring a built-in DSP instruction set and single-precision floating-point unit (FPU), the series is said to be suitable for industrial control, automotive electronic peripherals, and other applications.

Detailed specifications include various peripheral functions such as hardware encryption/decryption engine, hardware key storage, TRNG (True Random Number Generator), secure boot (provides Root of Trust function), CAN FD 2 sets, and USB 1 set.

In addition, it integrates various analog components such as △high-speed OTG △up to 24 channels of 16-bit PWM output △8 UARTs △4 SPI/I2S △2 Quad-SPIs △5 I²C and real-time clock (RTC) △2 sets of analog comparators △12-bit 16-channel SAR ADC.

Nuvoton also supported the software stack, including the NuMaker-M463KG development board and the Nu-Link debugger tool. Compatible with various development environments, including Keil MDK, IAR EWARM, and the Eclipse IDE with GNU GCC, these tools enable developers to seamlessly create, debug, and deploy applications, streamlining the product release process.

Nuvoton pledged that “the NuMicro M463 MCU series will continue to drive innovation in MCU technology while providing high-performance, highly secure products that meet customer needs in a dynamically evolving market.”
