Headquartered in Shanghai, China, Espressif designs, manufactures and sells the ESP series, which specializes in IoT applications, as chips and his modules. Previously, Tensilica’s Xtensa CPU was used, but this time, ESP32-C3 using RISC-V was introduced for volume zone application as a successor to ESP8266, which is one of the most shipped products. .. The RISC-V core of the ESP32-C3 operates at a maximum clock speed of 160MHz. With 22 configurable GPIOs, 400 KB of internal RAM, and low power mode support, it can be used in many use cases for wirelessly connected devices. There are multiple variations with availability to use external flash. By supporting high temperature operation, it is ideal for use cases such as industrial and lighting, but it can also be applied to a wide range of applications such as smart homes, industrial automation, healthcare and home appliances.
Three types of chips have been announced this time: ESP32-C3, ESP32-C3FN4, and ESP32-C3FH4. All are packaged in a 5mm * 5mm QFN32. The ESP32-C3 does not have a built-in flash and has an operating temperature range of -40 ° C to 105 ° C. As a multi-die chip with a built-in 4MB QPI flash in a 5mm * 5mm QFN32, ESP32-C3FN4 with an operating temperature range of -40 ° C to 85 ° C and ESP32-C3FN4 with an operating temperature range of -40 ° C to 105 ° C is offered.
The two modules announced this time are the high-density mounting type ESP32-C3-MINI-1 announced last year and the normal mounting type (photo) ESP32-C3-WROOM-02. With a 53-pin 13.2mm x 16.6mm x 2.4mm package, the ESP32-C3-MINI-1 is pin compatible with the ESP-WROOM-02 / 02D module of the volume zone product ESP8266. With a 19-pin 18mm x 20mm x 3.2mm package, the ESP32-C3-WROOM-02 is a general purpose Wi-Fi and Bluetooth LE module with a rich peripheral set. In this announcement, only the built-in antenna version was announced, and there is no module with an IPEX terminal.

It is said.
ESP32 is a product that Espressif introduced a new style to the embedded system in 2015 with various ideas and mounting technologies. Power consumption is reduced by a finer process than conventional MCUs. We responded to the demands of the IoT era by creating a Wi-Fi module that has both a TCP / IP stack and an MCU function. Equipped with a large mask ROM library, APIs are prepared for users to realize various wireless communication functions with a high degree of freedom using this mask ROM, large internal RAM, and external flash. It is worth noting that RISC-V is being adopted in the main products of modules that are becoming widely used in the IoT industry. .. Manufactured using the TSMC process 40nm process.
