NUTINY-SDK-NUC029SGE USER MANUAL

1 OVERVIEW

NuTiny-SDK-NUC029SGE is a specific development tool for NuMicro®NUC029SGE. With the

NuTiny-SDK-NUC029SGE, user can develop and verify the application program easily.

The NuTiny-SDK-NUC029SGE includes two portions. One is NuTiny-EVB-NUC029SGE and the

other is Nu-Link-Me. NuTiny-EVB-NUC029SGE is the evaluation board and Nu-Link-Me is its

Debug Adaptor. Thus, user does not need other additional ICE or debug equipment.

The NUC029SGE can bridge the gap and replace the cost equivalent to traditional 8- and 16-bit

microcontroller by 32-bit performance and rich functions. The NUC029SGE supports a wide range

of applications from low-end, price sensitive designs to computing-intensive ones and provides

advanced high-end features in economical products.

The NuMicro®NUC029xGE of NUC029 series microcontroller based on the Arm®Cortex®-M0

core operates at up to 72 MHz. With its crystal-less USB 2.0 FS interface, it is able to generate

precise frequency required by USB protocol without the need of external crystal. It features

adjustable VDDIO pins for specific I/O pins with a wide range of voltage from 1.8 V to 5.5 V for

various operating voltages of external components, a unique high-speed PWM with clock

frequency up to 144 MHz for precision control, and an integrated hardware divider to speed up

the calculation for the control algorithms. Apart from that, the NUC029xGE also integrates

SPROM (Security Protection ROM) which provides a secure code execution area to protect the

intelligent property of developers. The NuMicro®NUC029xGE of NUC029 series is ideal for

industrial control, motor control and metering applications.

The NuMicro® NUC029xGE of NUC029 series supports the wide voltage range from 2.5 V to 5.5

V and temperature ranging from -40℃to 105℃, up to 256 Kbytes of Flash memory, 20 Kbytes of

SRAM, 4 Kbytes of ISP (In-System Programming) ROM as well as ICP (In-Circuit Programming)

ROM and IAP (In-Application Programming) ROM in 48-, 64-, 128-pin packages. It also supports

high immunity of 8KV ESD (HBM)/4KV EFT. It is also equipped with plenty of peripherals such as

USB interface, Timers, Watchdog Timers, RTC, PDMA, EBI, UART, Smart Card Interface, SPI,

I²S, I²C, GPIO, up to 12 channels of 16-bit PWM, up to 20 channels of 12-bit ADC, analog

comparator, temperature sensor, low voltage reset, brown-out detector, 96-bit UID (Unique

Identification), and 128-bit UCID (Unique Customer Identification).

Besides, the NUC029SGE is equipped with ISP (In-System Programming) and ICP (In-Circuit

Programming) functions, which allow the user to update the program memory without removing

the chip from the actual end product. The NUC029SGE also supports In-Application-

Programming (IAP) function, user switches the code executing without the chip reset after the

embedded flash updated.

NUTINY-SDK-NUC029SGE USER MANUAL

2 NUTINY-SDK-NUC029SGE INTRODUCTION

The NuTiny-SDK-NUC029SGE uses the NUC029SGE as the target microcontroller. Figure 2-1 is

NuTiny-SDK-NUC029SGE for the NUC029SGE, the left portion is called NuTiny-EVB-

NUC029SGE and the right portion is Debug Adaptor called Nu-Link-Me.

The NuTiny-EVB-NUC029SGE 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

NUC029SGE features. The NuTiny-EVB-NUC029SGE can be a real system controller to design

user’s target systems.

Nu-Link-Me is a Debug Adaptor. The Nu-Link-Me Debug Adaptor connects your PC's USB port to

your target system (via Serial Wired Debug Port) and allows you to program and debug

embedded programs on the target hardware. The Nu-Link-Me V3.0 also supports VCOM function,

which gives users more flexibility when debugging. To use the Nu-Link-Me Debug adaptor with

IAR or Keil, please refer to “Nuvoton NuMicro®IAR ICE driver user manual “or Nuvoton NuMicro®

Keil ICE driver user manual” in detail. These two documents will be stored in the local hard disk

when the user installs each driver. To use Nu-Link-Me 3.0 VCOM function, please refer to

Chapter 5.
