1 Introduction
The Nu-LB-NUC140 is an evaluation board for NUVOTON’s Cortex™-M0 based
NUC100 series microcontrollers, and provides a complete development environment for
NUC140 microcontrollers which has 4K/8K/16K byte internal SRAM and
32K/64K/128K-byte embedded flash, build-in 1.8V LDO, integrated Timers, Watchdog
Timer, RTC, PDMA, UART, SPI/SSP, I2C, PWM Timer, GPIO, LIN, CAN, USB 2.0 FS
Device, 12-bit ADC, Analog Comparator, Low Voltage Detector and Brown-out detector.
It supports Brown-Out Detector.
The Nu-LB-NUC140 learning board is similar to other development boards. Users can
use it to develop and verify applications to emulate the real behavior. The on-board chip
covers NUC140 series features. The Nu-LB-NUC140 can be a real system controller to
design users’ target systems.
This user manual provides information about hardware features and information about
using this learning board. The following figure shows the Nu-LB-NUC140 board.
