Series

Nuvoton® NuMicro® NUC029 series is a new microcontroller product line that designed for industrial control applications. NuMicro® NUC029 series provide robust immunity and strong anti-interference ability (ESD HBM 7KV / EFT 4.4KV). NuMicro® NUC029 series can operate with 2.5V ~ 5.5V operating voltage, -40°C to +105°C temperature range, 24MHz~72 MHz operating frequency, 16 KB ~ 256 KB Flash, 2 KB ~ 20 KB SRAM, equipped with high performance with plenty peripherals such as 12-bit ADC, UART, PWM, SPI, I2C…etc. Specific parts support hardware divider, comparator, USB 2.0 full-speed device bus. NuMicro® NUC029 series provides diverse packages (TSSOP20, QFN33, QFN48, LQFP48, LQFP64) to meet customer’s product requirement. NuMicro® NUC029 SEE/LEE/SGE/LGE are enhanced with USB 2.0 full-speed crystal-less device feature to reduce BOM cost and physical size.
