Nuvoton NuMicro NUC131U automotive microcontroller

Nuvoton Technology has launched the NuMicro NUC131U, a 32-bit microcontroller for automotive applications. The product is qualified by AEC-Q100 Grade 2 and features a built-in Controller Area Network (CAN) 2.0 B interface. Its high performance and high immunity make it suitable for automotive body control, automotive CAN modules, on-vehicle diagnostic systems (OBD), dashboard control and automotive lighting applications.

The series features an Arm Cortex-M0 core running up to 50 MHz, 68 KB Flash, 8 KB SRAM and 4 KB LDROM to support CAN boot loader update operating voltage from 2.5 to 5.5 V. It has an operating temperature from -40 to +105°C. It is equipped with a rich set of peripherals including six sets of UART, two sets of I²C, one set of SPI and 24 channels of 100 MHz PWM to drive the stepping motor or HVAC compressor. A 12-bit ADC provides up to 800 kSPS to sense voltage, current or temperature sensors for automotive applications to reduce the number of external peripheral components and the form factor of the end product.

The series is available in LQFP48 (7 x 7 mm) and LQFP64 (7 x 7 mm) packages. Multiple IDEs are supported, including the Keil MDK Nuvoton Edition, IAR EWARM and NuEclipse; the Keil MDK Nuvoton Edition (for NuMicro Cortex-M0 family) and NuEclipse are free to use. Easy-to-use software development tools including PinView and PinConfig are available to speed up the time to market.
