Panasonic has released a new 2.4 GHz 802.11b/g/n embedded Wi-Fi module with all security features required for compliance with WPA2 and WPA3-Personal Wi-Fi security standards. The new PAN9520 is based on the Espressif ESP32-S2 microcontroller, which includes a high-performance 32-bit Xtensa LX7 CPU, a high sensitivity wireless radio, a baseband processor, bootloader and 320 kb of SRAM. An encryption unit supports a range of security and encryption protocols, including CCMP, TKIP, WAPI, WEP, BIP, and AES.
The integrated crystal ensures connection performance over the entire temperature range and lifetime. Tomislav Tipura, Wireless Connectivity Product Manager at Panasonic Industry mentioned that although the PAN9520 is one of the smallest modules on the market, it offers a rich set of peripherals. This set comprises full-speed USB OTG, SPI, UART, I²C and many more. Tipura further summarizes that being a fully integrated module, the PAN9520 can be implemented quickly and easily into end-product designs - with or without a host controller.
The module includes Flash memory, a 40 MHz crystal oscillator and a chip antenna. Panasonic offers two variants with either 2 MB PSRAM and 4 MB Flash or no PSRAM and 1 MB Flash. The PAN9520 supports access point mode and station mode in parallel, allowing simultaneous Wi-Fi connections to smart devices and home network routers.
Using the Espressif IoT Integrated Development Framework (ESP-IDF), engineers can develop software for a wide range of applications, and access numerous software examples which can be used to speed up development.
