1. introduction
1.1 overview
the 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 ues 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”

referred to ipc/jedec standard.
peak temperature : <250°c
number of times : ≤2 times
4.3 patch wifi modules installed before the notice:
wifi module installed note:
1. please press 1 : 1 and then expand outward proportion to 0.7 mm, 0.12 mm thickness when open a stencil
2. take and use the wifi module, please insure the electrostatic protective measures.
3. reflow soldering temperature should be according to the customer the main size of the products, such as the temperature set at 250 + 5 ℃ for the mid motherboard.
about the module packaging, storage and use of matters needing attention are as follows:
1. the module of the reel and storage life of vacuum packing: 1). shelf life: 8 months, storage environment conditions: temperature in: < 40 ℃, relative humidity: < 90% r.h.
2. the module vacuum packing once opened, time limit of the assembly:
card: 1) check the humidity display value should be less than 30% (in blue), such as: 30% ~ 40% (pink), or greater than 40% (red) the module have been moisture absorption.
2.) factory environmental temperature humidity control: ≦ 30% ℃, ≦ 60% r.h..
3). once opened, the workshop the preservation of life for 168 hours.
3. once opened, such as when not used up within 168 hours:
1). the module must be again to remove the module moisture absorption.
2). the baking temperature: 125 ℃, 8 hours.
3.) after baking, put the right amount of desiccant to seal packages.
