ESP32-C6 přichází s podporou Wi-Fi 6

Espressif Systems oznámilo nový hardware se jménem ESP32-C6. C6 v sobě skrývá novinku ve formě podpory Wi-Fi 6.

Wi-Fi 6 funguje na stejných frekvenčních rozsazích jako jeho předchůdci a to 2.4GHz a 5GHz, ale nabízí vylepšení v podobě vyšší rychlosti (jiná modulace), podpora zabezpečení WPA3 a 8 MIMO streamů.

Bohužel, ESP32-C6 není plnohodnotné zařízení a tak podporuje pásmo pouze 2.4GHz.

ESP32-C6 kromě vylepšené Wi-Fi části obsahuje i Bluetooth ve verzi 5. ESP32-C6 bude obsahovat pouze jedno jádro, ale bude to jádro RISC-V s frekvencí až 160 MHz.

Těšit se tak dále můžeme na 384 kB ROM a 400 kB SRAM, 22 GPIO, ADC, SPI, UART, I2C, I2C a také PWM.

„However, the 802.11ax standard used in ESP32-C6 contains a variety of extra features added to the current Wi-Fi standard, and we have carefully chosen those features that provide concrete benefits for IoT devices. ESP23-C6 supports the OFDMA (Orthogonal Frequency Division Multiple Access) mechanism for both uplink and downlink communications. It also supports MU-MIMO capability for downlink. Both of these techniques provide the ability to work with high efficiency and low latency in congested wireless environments. One more important feature of the 802.11ax standard is the Target Wake Time (TWT), which allows the devices to sleep for an extended time-period, with assistance from an 802.11ax-capable, Wi-Fi access point. This feature in ESP32-C6 will allow our customers to build battery-operated, connected devices that can last for years on battery, while staying connected throughout.

Espressif continues to safeguard the security of connected devices through hardware and software features. ESP32-C6 comes with RSA-3072-based secure boot, AES-128-XTS-based flash encryption, digital signature and an HMAC peripheral for identity protection, as well as cryptographic accelerators for improved performance. These features ensure that the devices built with ESP32-C6 can provide the desired level of security.„
