The PAN9520 from Panasonic is a 2.4 GHz Wi-Fi (802.11 b/g/n) embedded module that is based on the Espressif ESP32-S2 chipset. It has an integrated chip antenna and QSPI memory that enable the module to be used in a variety of stand-alone or host-controlled applications. The module has an integrated crystal that ensures connection performance over full temperature range and lifetime.
The PAN9520 combines a high-performance CPU, high-sensitivity wireless radio, baseband processor, MAC, encryption unit, ROM bootloader, chip-internal SRAM, and module-internal QSPI flash and PSRAM. It also has features like CCMP, TKIP, WAPI, WEP, BIP, and an AES accelerator for secure data connections.
The module delivers a data rate of up to 150 Mbps with 20/40 MHz channel bandwidth in the 2.4 GHz band. It has a Tx power of 19.5 dBm and has an Rx sensitivity of -97 dBm. The PAN9520 requires a DC supply of 3-3.6 V, consumes 310 mA of current in Tx mode and 68 mA of current in Rx mode. It can be controlled via SPI, I2S, I2C, ADC, DAC, UART, RMT, LCD, LED PWM, DVP 8/16 camera, and USB OTG interfaces.
The PAN9520 is available in an SMT module that measures 24 x 13 x 3.1 mm with an integrated chip antenna and is ideal for the integration of Wi-Fi connectivity into various electronic devices.
