2 Overview
Product Specification Rev. 1.1 Page 6
2 Overview
The PAN9420 is a 2.4 GHz 802.11 b/g/n embedded Wi-Fi module with integrated stack and API
that minimizes firmware development and includes a full security suite. The module is
specifically designed for highly integrated and cost-effective applications. The module includes
a fully shielded case, integrated crystal oscillators, and a chip antenna.
The module combines a high-performance CPU, high-sensitivity wireless radio, baseband
processor, medium access controller, encryption unit, boot ROM with patching capability,
internal SRAM, and in-system programmable flash memory. The module’s integrated memory is
available to the application for storing web content such as HTML pages or image data.
Parallel support of access point and infrastructure mode allows easy setup of simultaneous
Wi-Fi connections from the module to smart devices and home network routers.
The pre-programmed Wi-Fi SoC firmware enables client (STA), micro access point (uAP), and
Ad-hoc mode (Wi-Fi Direct) applications. With the transparent mode, raw data can be sent from
the UART to the air interface to smart devices, web servers, or PC applications.
The PAN9420 supports Over-the-Air firmware updates. In order to make use
of this feature, the customer needs to ensure that the appropriate
preconditions are fulfilled and that a suitable environment is provided,
particularly with regard to:
•Module configuration
•Utilization of the related module interface commands
•Server infrastructure and application
Please refer to the Panasonic website for related documents 6.2.2 Product Information.
