8/1/2023 0 Comments Fuse blocks![]() ![]() According to IEC 257, the rated current is determined by the rated accepted power of a fuse-holder. Considerable differences exist between the IEC and the UL standards regarding the rated current of a fuse-holder. In the following, some of the most important differences between the two standards will be indicated.įrom an application point of view, a fuse-holder is characterized by the features discussed in the previous section by its rated values for voltage, current, and accepted power. In the case of fuse links, compliance with the UL-standard does not usually mean that the fuse-holder under consideration meets IEC-requirements and vice versa. 2 to this publication dated January 1989.īoth standards show considerable differences. IEC-publication 257 (1968) and Amendment no.The most important standards for fuse-holders, which specify requirements, characteristics and testing methods are: How much is available to spend on safety and reliability?.Should the fuse only be accessible from outside the appliance?.Should the end customer of the appliance have access to change the fuse?.How often will the fuse need to be replaced?.Will the fuse need to accessible for replacement?.The first step is to answer the following questions: Selection of the Fuse and Holder Solution ![]()

8/1/2023 0 Comments 2017 planner studio c![]() When our creation finally arrived, we first gave ourselves a pat on the back and showed it off to everyone because we were so proud, and then we started critiquing it and seeing the imperfections, or should we say room for growth. Our inaugural year was tough because we were creating something out of nothing, pulling all our ideas together and making what we thought were the best decisions. We won't go into all of the details here, but feel free to refresh before we get started.įor the 2016 planner, the bulk of the decisions we made were based on personal preferences, our experiences with previous planners, and a focus group we had try out a sample. We featured a similar series last year, Planning a Planner, where you can read all about the hard work we put into getting the 2016 planner off the ground. Over the next month as we ramp up for the UPstudio 2017 Planner release we will be sharing some of the behind the scenes work in a four part blog series, "Planning a Planner v2017". The process was challenging and we learned a ton. We are proud of what we were able to create. 2016 was the inaugural year for the UPstudio planner. We have tackled a lot of other fun projects along the way, but our planner is still our main focus. UPstudio was founded on the idea of creating a planner that is affordable, attractive, versatile, and fit for people in all walks of life. So please, never hesitate to shoot us an e-mail or contact us via social media, we would love to hear from you. We are genuine when we say that we are always looking for areas to improve and grow. Thank you to everyone who took the time to respond to our inquires and share your thoughts. First off, we appreciate all of the honest feedback we received regarding the UPstudio 2016 Planner. ![]() 8/1/2023 0 Comments Nuvoton ice driver download![]() ![]() Both tools are great to do the job, but they are not free. Since it is an 8051 based microcontroller, it can be programmed using Keil u vision with C51 compiler, or IAR Embedded workbench. But for nuvoton programming, this is the one thing that lags. For the industry-leading microcontroller manufacturers, such as a microchip, nordic, STMicroelectronics - they all provide free c compiler and IDE. Getting the proper IDE and compiler is an important thing for any microcontroller programming. IDE and Compiler for N76E003 Microcontroller It has Macro-USB connectivity, Offline programming button, and status indicator using 4 LEDs (ICE, ISP, RED, and GREEN). The programmer that we will use in our tutorial is shown above. However, for those who are willing to use the official Nu-link programmer, it is available for purchase as the Nu-Tiny SDK development board. Nu-Link as N76E003 Programmerįor programming this microcontroller, we are using an unofficial Nu-link programmer which is a low cost alternative available in the online stores. Other than this, external crystal and required capacitors pad are also available without the components that can be very useful during further development where the external oscillator is required. There is also a test LED available that can be configured using the code. It also has a power LED and a reset button to reset the microcontroller unit. However, it has a filter capacitor at the input. In the below image, the internal circuit diagram for the development board is shown.Īs we can see in the schematic, the development board doesn't have any kind of voltage regulator be it linear or LDO. The board is just a simple development board with all pinouts from the microcontroller unit. The image of the N76E003 Development board that we will use in this tutorial is shown below. But since this board is hard to find in India, and it does cost high, a standard bare minimum development board is available online. The official development board for nuvoton N76E003 is the NuTiny-N76E003 SDK board with a programmer. Let's start to find out how to create the programming environment of the N76E003. ![]() Since the microcontroller is finalized with Nuvoton N76E003at20, it's time to find out the proper hardware and software that is required for programming the microcontroller. Selecting the Hardware and Software Development Tools In this specific tutorial, we will learn how to set-up the N76E003 programming environment as well as how to write the first hello world program of the embedded - blinking an LED. Since it is a very cheaper one and has a wide range of features, you can find this microcontroller interesting if you are a beginner, or doing hobby projects or a professional one. In this series of tutorials, we will learn how to program the N76E003 microcontroller unit, more specifically the N76E003at20 microcontroller. Additionally, it doesn't require an oscillator, also, since it’s equipped with 16 MHz internal RC oscillators. Now you should be wondering what is the price? It's less than 0.4$ (30 Rs) only. Thus, during the development of the production phase, the nuvoton micro-controller is getting an upper edge due to the low price and high feature supports.įor example, nuvoton N76E003 is a 20-pin microcontroller unit that supports 18 I/O pins out of 20 with features like UARTs, I2C, 6-Ch PWM, SPI, wake up functions, Brownout detectors with an 8-bit high performance 8051-based microcontroller unit. But the most important thing is that it provides all features at a very low-cost margin. The company offers very useful microcontrollers, mixed-signal chips, microprocessors with extremely high specification. However, nuvoton is a Taiwan based semiconductor company that was spun-off as a Winbond affiliate in 2008. ![]() But when we differentiate those microcontrollers with form factor vs features vs price, it gets hectic to choose one. There are lots of microcontrollers available from reputed companies such as PIC, Texas Instruments, ST and the list goes on. ![]() |
