Wireless Connectivity

This Wi-Fi 6 support is optimized for IoT devices, and the SoC supports a 20MHz bandwidth for 802.11ax mode, and a 20/40MHz bandwidth for 802.11b/g/n mode. The 802.11ax mode supports features like OFDMA, MU-MIMO which help to provide reliable and low latency connection, Target Wake Time function which can enable ultra-low power applications. Additionally, Bluetooth 5 (LE) radio supports long-range operation through advertisement extension and coded PHY. It also supports 2 Mbps of high throughput PHY. The SoC shall also support the BLE-Mesh 1.1 protocol.

System and Memory

In terms of CPU, ESP32-C61 has a single-core, 32-bit RISC-V microcontroller that can be clocked up to 160 MHz It has a 320KB on-chip SRAM, a 256KB ROM, and works with Quad SPI flash. Notably, the SoC introduces support for PSRAM with Quad SPI of up to 120MHz, offering developers to focus on application development without worrying about memory optimizations. The larger memory availability also provides better future proofing for upgrades.

Security

In continuation of Espressif’s philosophy, ESP32-C61 places a strong emphasis on affordable security, incorporating features such as secure boot, flash and PSRAM encryption, and cryptographic accelerators. It also has ECDSA based Digital Signature Peripheral in hardware, safeguarding private keys from software access. The addition of Trusted Execution Environment (TEE) using Access Permission Management (APM) hardware block and Physical Memory Protection (PMP) provides flexibility in application security management.

Optimized Peripherals

ESP32-C61 encompasses standard microcontroller peripherals like I2C, I2S, SPI, UART, LED-PWM, ADC, Timers, and DMA. Specialized peripherals include the Event Task Matrix for automation-triggered tasks and the Zero-crossing comparator for easy zero-crossing detection.

ESP32-C61 will be supported through Espressif’s mature IoT Development Framework (ESP-IDF), so that our customers can benefit from their familiarity with our field-proven platform that already powers millions of connected devices. The ESP-Matter-SDK will also include the support for ESP32-C61 for creating Matter enabled products. With the availability of PSRAM, the ease of development as well as the applications which can be supported on this unique product is unparallel. For the customers who would like to use ESP32-C61 as a communication’s co-processor with an external host, ESP-Hosted and ESP-AT firmware will also be available.
