Getting Started with Espressif’s ESP32-C3-DevKITM-1 on Arduino IDE

Posted on 13 July, 2021 by Saumitra Jagdale

Espressif Systems ESP32-C3-DevKit M-1 is an extremely powerful board for your IoT applications. Driven by the ESP32-C3FN4 chip, this low-power, low-cost, Wifi-Bluetooth-enabled board has its own unique place in the ESP32 board line-up.

You can program your ESP32-C3-DevKITM-1 module in four ways:

ESP-IDF
Arduino IDE
Eclipse Plugin
VS Code Extension

Interfacing the ESP32-C3-DevKITM-1 on Arduino IDE provides us with the flexibility, compatibility, and reliability of a much simpler and easy-to-use UI also boosting the programming speed. In this article, we focus on the programming of ESP32-C3 with Arduino IDE.

Getting Started with Arduino IDE

Arduino IDE being highly popular and convenient to most programmers also has support for ESP boards. For that, you need to add the board’s Github repository to the IDE which can be found here.

For the ESP32-C3-DevKITM-1 board, you need to use the development release link:

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json

First, make sure that you have the latest version of the Arduino IDE installed on your computer. Here are the steps to interface ESP32-C3-DevKITM-1 on Arduino IDE.

Step1: In your Arduino IDE window, go to File menu -> Preferences

Step2: Once the preferences menu is open, Enter https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json in the Additional Boards Manager URLs field and hit OK.

Step3: Now go to the Boards Manager from the Tools menu.

Step4: In the Boards Manager, search esp32 by Espressif Systems. Install the latest 2.0.0 version.

Now, once the installation is complete, you can see the ESP32C3 Dev Module in the boards’ section of the Tools menu. Select it.

Now, under the File menu, in the examples section, you can see some inbuilt examples.

Select a proper port for your board with preferred settings. The port number of the board can be found using Device Manager on your PC.

Here, we executed an ESP32-> Time-> SimpleTime example which connects your board to a WiFi network to obtain and display the current date and time on the serial monitor. Enter your network’s SSID and password in the code. Just compile the sketch and then upload it to the board. Also, open the Arduino IDE’s Serial Monitor at a baud rate of 115200 to view the result.

Before uploading, put the ESP32C3 board in programming mode by long-pressing the boot button and simultaneously pressing the reset button once, and then releasing the boot button.

You can now build your own ESP32 C3 projects on Arduino IDE.

SK hynix Starts Mass Production of 1anm DRAM Using EUV Equipment

Posted on 12 July, 202112 July, 2021 by mixos

SK hynix Inc. announced that it has started this month mass production of the 8 Gigabit (Gb) *LPDDR4 mobile DRAM based on the 1anm, which is the fourth generation of the 10nm process technology.

* LPDDR4 (Low Power Double Data Rate 4): Low power DRAM for mobile devices. DDR refers to DRAM with the specifications that JEDEC standardized and the generation has advanced from one to four.

As the semiconductor industry classifies the 10nm DRAM products, naming them after the alphabets, the 1a technology is the fourth generation, following the first three generations of the 1x, 1y, and 1z. SK hynix plans to provide the latest mobile DRAM products to smartphone manufacturers from the second half of 2021.

This is the first time that SK hynix adopted the *EUV equipment for mass production after proving the stability of the cutting edge lithography technology through partial adoption for its 1ynm DRAM production.

* EUV (Extreme Ultraviolet): lithography technology that uses extreme ultraviolet

As technology migration continues to ultra-micro levels, an increasing number of semiconductor companies are adopting the EUV equipment for the photo process where circuit patterns are drawn on the wafer surfaces. Industry experts believe that a semiconductor company’s leadership in technology will depend on how it can fully take advantage of the EUV equipment. SK hynix plans to use the EUV technology for production of all its 1anm DRAM products going forward as it has proved the stability of the process.

SK hynix expects the new technology to bring an improvement in productivity, and further boost cost competitiveness. The company expects the 1anm technology to lead to a 25% increase in the number of DRAM chips produced from the same size of a wafer, compared with the previous 1znm node. SK hynix anticipates that the 1anm DRAM will also likely help alleviate the supply and demand conditions of the global markets following an increase in DRAM demand globally.

The new product stably runs 4266Mbps, the fastest transfer rate in a standard LPDDR4 mobile DRAM specification, and has reduced power consumption by 20%. It is a meaningful accomplishment for SK hynix as it aims to reduce carbon dioxide emission as part of its commitment to the environmental, social and governance (ESG) management.

SK hynix will apply its 1anm technology to its DDR5 products, the world’s first next-generation DRAM launched in October 2020, from early next year.

Cho Youngmann, Vice President at SK hynix, said that

“With improved productivity and cost competitiveness, the latest 1anm DRAM will not only help secure high profitability, but also solidify SK hynix’s status as a leading technology company with early adoption of the EUV lithography technology for mass production.”
