New Espressif ESP32-S3 Microprocessor Supports AI Instructions for IoT Devices

Espressif ESP32-S3 Microprocessor

Addressing the rising needs of the AIoT (AI + IoT) market, ESP32-S3 from Espressif is a dual-core XTensa LX7 MCU that comes with 2.4 GHz WiFi 4 and Bluetooth 5 connectivity, expanded GPIO, AI-focused instructions, hardware-accelerated security features. Compared to its previous version of ESP32, this new MCU supports larger, high-speed octal SPI flash, and PSRAM with configurable data and instruction cache.

 

The device has 512 KB of internal SRAM and its Wi-Fi and Bluetooth-Low-Energy 5.0 connectivity provides long-range support. It has 44 programmable GPIOs and supports a rich set of peripherals. The vector instructions that provide acceleration for neural networks and signal processing loads make ESP32-S3 best suited for AI applications. Security features with an HMAC controller for message authentication, a Digital Signature (DS) module that provides hardware-accelerated message signing, secure boot capability that verifies the RSA-PSS signature of an application image before executing it are the notable features of the new MCU.

 

Additional encryption includes "Flash Encryption" for off-chip flash memory. "World Controller" peripheral makes fully-isolated execution environments possible, thereby isolating security-sensitive data tasks from the rest of the application.

 

Key Features and Specifications of ESP32-S3

  • CPU: Dual-core Tensilica LX7 up to 240 MHz with additional vector instructions for AI acceleration and ULP core to handle low power modes

 

  • Memory: 512 KB of internal SRAM

 

  • Storage: Octal SPI flash and PSRAM support (supports larger, high-speed devices compared to ESP32)

 

  • Wi-Fi + Bluetooth LE 5.0 Wireless Connectivity: 2.4 GHz 802.11 b/g/n Wi-Fi 4 with 40 MHz bandwidth support and Bluetooth Low Energy (BLE) 5.0 connectivity with long-range support, up to 2Mbps data rate.

 

  • Rich set of IO Peripherals: 44x programmable GPIOs (10 more than ESP32), SD/MMC host, SPI, I2C, PWM, UART, RMT (Remote Control), TWAI (Two-Wire Automotive Interface), ADC, DAC, I2S, USB OTG, Capacitive touch input, ULP (Ultra-Low-Power) core that supports multiple low-power modes in a variety of such use-cases.

 

  • Security: AES-XTS-based flash encryption, RSA-based secure boot, digital signature peripheral, and an HMAC module (similar to a secure element), “World Controller” peripheral that provides two fully-isolated execution environments and enables a trusted-execution environment or a privilege-separation scheme.

 

  • AI Acceleration Support: Additional support for vector instructions in the MCU, which provides acceleration for neural network computing and signal processing workloads. The software libraries for the above-mentioned optimized functions will become available very soon, in the form of updates to ESP-WHO and ESP-Skainet.

 

  • Mature Software Support: Supported by Espressif’s popular ESP-IDF platform that already powers millions of devices on the market. ESP-IDF comes with rigorous testing, regular updates, and an unparalleled support policy. Based on ESP-IDF’s mature software architecture, developers can easily build applications anew or migrate their own applications to the ESP32-S3 platform and continue working with the trusted ESP-IDF tools and APIs.

 

The new ESP32-S3 stands out in terms of connectivity, AI computing power, security, IO availability, and peripheral interfaces. The MCU will provide device manufacturers and developers with a cost-effective and easy-to-develop AIoT solution platform, for an enhanced experience of smart networking.

Hey There!

I noticed while looking over your website that it doesn't have a lot of articles...and that's almost certainly limiting the number of prospects (buyers, customers, clients) that find you online...

Maybe you just don't have the time to produce high-quality articles for your site? Or maybe you're just not sure what topics to write about...?

I have a unique strategy that I'd like to discuss with you...one that involves researching questions that people are asking every day on Google. Questions being asked by your ideal customer/client.

These questions are different/special because there are very few websites that answer these questions on the entire web...in fact, many times there are none that answer it.

That's where we come in. Our company writes articles that rank very quickly because there is virtually no competition.

Let's set up a meeting so I can show you more about our strategy, including examples of these "special questions" along with the traffic and rankings we are generating...I'll show you how we can provide content for your website that will gain you fast rankings, traffic and sales for your business.

I'm available this week to chat...let me know what day and time works best for you.

Thanks so much!
Shawna
