The Panasonic PAN9520 is a 2.4 GHz 802.11 b/g/n embedded Wi-Fi module based on Espressif's ESP32-S2. This highly integrated, low power, single-core Wi-Fi microcontroller SoC incorporates a high-performance Xtensa® 32-bit LX7 CPU. It is also designed for security and cost efficiency while maintaining high performance.
Panasonic's PAN9520 with integrated chip antenna and QSPI memory.
The integrated chip antenna and QSPI memory make the PAN9520 suitable for a wide range of stand-alone and host-controlled applications. It is one of the smallest devices on the market (24 mm x 13 mm x 3.1 mm) and enables a wide range of peripherals via interfaces such as full-speed USB OTG, SPI, UART, and I2C, among others. The module is available either as a 4 MB Flash version with 2 MB PSRAM or as a 1 MB Flash version without PSRAM. Application areas include building automation, medical technology, and robotics, as well as smart city infrastructures. The Panasonic PAN9520 is available at www.rutronik24.com.
Panasonic combines a high-performance CPU, a baseband processor (BB), a high-sensitivity wireless radio, a ROM bootloader, and a medium access controller (MAC) in the PAN9520. It also contains an encryption unit, chip-internal SRAM as well as module-internal QSPI flash, and PSRAM (4 MB flash version). The module guarantees a secure data connection thanks to BIP, CCMP, TKIP, WAPI, WEP, and an AES accelerator. The integrated quartz ensures connection performance over the entire service life and at a temperature range from -40 °C to 85 °C. Simultaneous support of Access Point and Station Mode ensures easy setup of multiple Wi-Fi connections from the module to smart devices and home network routers.
The Espressif Integrated Development Framework (ESP-IDF) enables the development of software for a wide range of applications using a large selection of program examples.
