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 320kbytes 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. “Although the PAN9520 is one of the smallest modules on the market, it offers a rich set of peripherals,” said Tomislav Tipura, Wireless Connectivity Product Manager at Panasonic Industry. This set comprises full-speed USB OTG, SPI, UART, I²C and many more.

“Being a fully integrated module, the PAN9520 can be implemented quickly and easily into end-product designs - with or without a host controller.”

It includes Flash memory, a 40MHz crystal oscillator and a chip antenna. Panasonic Industry 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 WiFi 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.
