“捷博 QCA4004 低功耗WIFI串口模块”详细介绍
1. Introduction
1.1 Overview
The QCA4004 is a single chip 1x1 802.11b/g/n MIMO solution optimized for low-power embedded applications with single-stream capability for both transmit and receive. Frame aggregation, reduced inter-frame spacing (RIFS), and half guard intervals provide improved throughput on the link. Additional 802.11n performance optimization, such as 802.11n frame aggregation (A-MPDU and A-MSDU), is provided by drivers that support SDIO bus transaction bundling (a form of bus aggregation) and low-overhead host assisted buffering (Rx A-MSDU and A-MPDU). These techniques can improve the performance and efficiency of applications involving large bulk data transfers (for example, file transfers or high-resolution video streaming). The typical data path consists of the host interface, mailbox DMA, AHB, memory controller, MAC, BB, and radio. The CPU drives the control path via register and memory access. External interfaces include USB LPM or SPI slave, reference clock, and front-end components, as well as optional connections such as UART, SPI/I2C, GPIO, JTAG. See the “System Block Diagram”
