NUC029LAN

The NUC029LAN from Nuvoton Technology is a 32-bit ARM Cortex-M0 microcontroller offering 50MHz operation with 64KB Flash and 4KB SRAM in an LQFP-48 package. As part of the NuMicro NUC029 series, it provides rich peripherals including dual SPI, I2C, and UART, 8-channel 12-bit ADC, and 8-channel PWM. The internal 22.1184MHz RC oscillator with 1% accuracy eliminates the need for external crystals. High ESD/EFT immunity (8kV/4kV) ensures reliable operation in harsh industrial environments.

The NUC029LAN is built around the ARM Cortex-M0 processor core connected to Flash, SRAM, and peripherals through an AHB/APB bus architecture. The CPU executes code from 64KB Flash at up to 50MHz, with access to 4KB SRAM for data operations. The clock system includes an internal 22.1184MHz RC oscillator and PLL for flexible frequency generation. The 12-bit SAR ADC converts analog inputs at up to 760kSPS. Communication peripherals support standard serial protocols. ISP and IAP enable firmware updates without hardware modifications. Brown-out detection and power-on reset ensure reliable startup and operation.
