The RA6W1 from Renesas is a Wi-Fi 6 SoC that operates in the 2.4 GHz and 5 GHz bands. It is designed as a standalone solution for low-power IoT applications requiring Wi-Fi connectivity. This SoC is based on the Armv8-M architecture and integrates a 160 MHz Arm Cortex-M33 core with 704 KB of on-chip SRAM and 256 KB of ROM, along with clock management, power management, security functions, and multiple interfaces. It supports Wi-Fi Station and Soft AP modes using 20 MHz channels, with Bluetooth coexistence support. This chip provides a transmit output power of 18.5 dBm and a receiver sensitivity of -96.9 dBm.
The RA6W1 includes an integrated secure crypto engine that supports encryption algorithms such as AES, DES/3DES, CHACHA, SHA-1/224/256, RSA, DH, and ECC for secure Wi-Fi communication. This wireless SoC provides a comprehensive networking software stack, including a TCP/IP stack with socket APIs. It can be controlled remotely via a rich set of interfaces, including SPI, I2C, I2S, eMMC, and UART. It requires a DC supply of 1.8 to 3.6 V and consumes 61 mA of current. This chip is available either in an FCQFN package measuring 5.6 x 6.4 x 0.4 mm or in a WLCSP package measuring 3.471 x 4.065 x 0.424 mm.
