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.

1.1 Nu-LB-NUC140

The Nu-LB-NUC140 is built around the NuMicro NUC140 MCU and provides versatile

external devices such as one SPI flash for data storage, one SD card slot supported by

SPI port1, one I2C interface serial EEPROM, one UART port with a RS-232 level shifter

for console connection (UART0) and one 5-pin SWD interface for ICE debugging.

The following lists the main components of the Nu-LB-NUC140 board:

Main Components:

1. MCU: NuMicroTM NUC140 MCU, which can run up to 50MHz operating speed.

2. GPIO extension slot: GPIO extension slots that support all the GPI/O pins interface.

3. AUDIO: On-board WAU8822 audio codec.

4. I2C EEPROM: On-board 24LC64 I2C E2PROM.

5. SPI FLASH: On-board 25Q16 SPI serial FLASH for data storage.

6. UART: UART port0 connecting to Male type DSUB-9 connector.

7. SD card Slot: One SD card slot supported by SPI port1.

8. Nu-Link ICE bridge: On-board ICE bridge parts.

9. LCD connector: Supports LCD module.

10. DC power jack: 5V/1A power adapter input.

11. LDO: A 5V to 3.3V/1A LDO that supports NUC140 and on-board devices.

12. USB: USB function connects.

13. Buzzer

14. Key Matrix

15. 7 Segment, LED

16. CAN interface

17. Variable resistance
