ACC1340

Overview

The ACC1340 is a fully integrated Wi-Fi radio single-chip solution supporting dual-band 2.4GHz and 5GHz operation. It implements IEEE 802.11a/b/g/n standards with hardware and embedded software for 802.11h Dynamic Frequency Selection (DFS). The device provides access to 24 DFS-supported 5GHz high-bandwidth channels, significantly expanding available spectrum compared to non-DFS alternatives. It integrates a 2.4GHz power amplifier to reduce external bill of materials. Security protocols include WAP, WAP2, WAPI, and WEP. The chip supports concurrent STA and Soft AP modes, enabling complex connection environments.

Feature Summary

• Supports Dynamic Frequency Selection (DFS) to unlock additional 5GHz bandwidth channels
• Integrates 2.4GHz power amplifier to minimize external component requirements
• Enables concurrent Station and Soft Access Point operational modes

Applications

• High-definition video streaming devices
• Uncompressed audio transmission systems
• Augmented reality applications
• Voice recognition interfaces

Procurement Notes

Verify the specific package variant against project requirements, as the component is available in 73-BGA and WLCSP configurations. Confirm that the target application environment complies with local regulations regarding DFS channel usage in the 5GHz band. Ensure firmware compatibility with the intended operating system, such as Linux, Android, or embedded RTOS platforms, prior to integration.

Selection Notes

Select this component when maximum available spectrum in the 5GHz band is critical for data-intensive applications. It is suitable for designs requiring reduced external BOM complexity due to the integrated 2.4GHz PA. Choose this IC over standard dual-band solutions if the application demands support for more than eight 5GHz channels through DFS implementation.
