6/25/2023 0 Comments Nuvoton ice driver downloadMegawin microcontrollers came with a factory ISP bootloader which will allow us to programme the microcontroller with either the ISP programmer or a cheap and affordable USB to TTL adapter. We can either use a Megawin OCD ICE Debugger or Megawin 8051 ISP Programmer or a USB to TTL converter. If you are interested to build the development board you can download the Gerber files from the following link:ĭownload Megawin Development Board PCB Gerber Fileįor Programming, we have multiple options. You can also work with the microcontroller and a breadboard. The development board is not at all necessary. Here below is the schematics and Gerber file for the MG82F6D17 Development board, in case you are interested to make a development board. You can find the picture of the MG82F6D17T20 soldered onto a TSSP20 to DIP adapter board below. I used the TSSOP variant because I already have them in stock. You can also find a DIP version of the chip. Here for the tutorial I have used a TSSOP to DIP adapter board since the microcontroller I have is the TSSOP variant MG82F6D17T20. There are no special development boards needed for Megawin microcontrollers because in our cae, the MG82F6D17 only requires very few complementary components to function. These Incredible chips are available at a very low cost of 0.35$ at this time, and before the silicon shortage, we have been able to buy them for 0.15$. The high-frequency PWM functionality makes the MG82FD17 a better choice for industrial applications. The above picture shows the TSSOP20 variant.īuilt-in CRC16 engine ensures the integrity of the flash content. Feel free to use whichever variant is available for you or you are comfortable with. Here for this tutorial, I will be using MG82F6D17T20, which is the TSSOP20 package variant because I already have them in stock. The MG82F6D17 is available in a variety of packages DIP20, TSSOP20, SSOP20, QFN20 and in SOP8 package with reduced pins. The table below summarizes an actual comparison of these chips. MG82F6D17 is much faster and feature-rich than its competitors. MG82F617A is equipped with 16KB Flash (with configurable Flash mapping for AP, IAP and ISP), 1KB DATA RAM (256B + 768B XRAM), CPU frequency up to 32MHz, Direct Memory Access (DMA), four 16bit Timers/Counters, 8 PWM channels with up to 96MHz, 8 Channel ADC with 12bit resolution and 800Ksps sampling rate, 2x UART, SPI, TWI RTC and many more features. Megawin’s MG82F6D17 is a low-cost microcontroller based on an advanced 1T 8051 core. The one that we will be using in this tutorial is MG82F6D17A which comes in the TSSOP20 package as shown below. The Megawin MG82F6D17 is a 20-pin Microcontroller that is available in both SMD and through-hole packages. Do note that these are retail prices and it will further be low when purchasing in high quantities. And here in India, at the time of writing this article the cheapest of all is MG82F6D17 priced at ~Rs.50, followed by STM8S003 at ~Rs.90, and then N76E003 priced at Rs.95. But regardless, these controllers should share the same level of price with a minimum price difference. Since all our readers are from a different geographic zone and the prices of the microcontrollers are highly fluctuating, it’s hard to compare them in terms of cost. And you can find features comparison of low-cost microcontrollers in the below table. Now arguably, which is the best low-cost microcontroller that is currently available in the market? To find that out we have compared the popular low-cost microcontroller STM8S003 from ST Microelectronics and N76E003 from Nuvoton Technology against the MG82F6D17 of Nuvoton. For this tutorial, we will be using an 8051 1T core microcontroller with an impressive list of features and attractive pricing namely the MG82F6D17 microcontroller.ĭifference between Megawin (MG82F6D17), Nuvoton (N76E003), and ST (STM8S003) Low cost Microcontrollers That includes their 8051 mcus based on 1T,12T/6T cores and with or without USB interface, And ARM Cortex_M0 based microcontrollers. Megawin has multiple product lines with them.
