The market trend of smart phones has always emphasized the high-speed processing core and complete peripheral functions, while the body and style also need to be thin and stylish. Therefore, in terms of market demand and project development cycle, how to achieve a balance between rapid development and functional integrity is the success factor for the product to occupy the market preferentially. In the past, WiFi, Bluetooth and GPS were all Distributed individual IC components are introduced into the entire hardware platform by design engineers. It is not only necessary to eliminate mutual interference of individual components, but also to pursue overall performance in a small and complicated space, which is really a difficult task. Implementing multiple functions directly on a single chip is the best solution.

The industry's latest 4-in-1 wireless module:
Pinjia Group selected AcSiP Inc. to launch the industry's latest product number S501 4 in 1 (WiFi b/g/n + Bluetooth 4.0 + GPS + FM Radio Rx) wireless module, this wireless module uses Is the MediaTek Inc. MT6628Q single chip, as a portable device market for smart phones, tablet computers, etc., the S501 is now mass-produced and shipped globally, together with MediaTek Inc. Android smart phone platform (MT6575/MT6577), it is the main weapon for the smart phone market.
AcSiP Inc. launched the S501, a 4-in-1 wireless module that integrates WiFi 802.11 b/g/n, Bluetooth, GPS (Global Positioning System) and FM Rx functions. The smallest packaged product dramatically reduces printed circuit board area and simplifies design resources.
Small package fits thin and light design
The S501 wireless module supports the wireless link function of the Android platform, enabling wireless devices such as smart phones, tablet computers, portable media players (PMPs), game consoles, and personal navigation devices (PNDs).
AcSiP Inc. is one of the few 4-in-1 wireless link modules that offer a wide range of mobile communication terminals. The S501 mobile communication terminal requires specifications and performance, including ultra-low power consumption to extend standby time and small. The package conforms to the thin and light mobile phone design, and the high cost performance can promote the popularization of the WiFi wireless communication market. The S501 can accelerate the time to market of the customer terminal products.
The development progress is relatively smooth
Pinjia Group believes that it is difficult to develop wireless modules that integrate WiFi, Bluetooth, GPS and FM functions. Therefore, compared to MediaTek Inc., there are related patent technologies in the past, plus AcSiP Inc. .) Focus on the development and design of wireless modules, so S501 will be better for the client development than the industry.
Lock smart phone S501 --- 4 in 1 plan to fire
AcSiP Inc. introduces S501 with MediaTek Inc.'s MT6628Q chip, which is highly integrated with Wi-Fi, Bluetooth, GPS and FM Radio to provide superior performance and high-end specifications for smart models. Mainstream products such as mobile phones, tablet computers, portable media players (PMPs), game consoles, and personal navigation devices (PDNs) have wireless link capabilities; in addition, advanced and sophisticated radio coexistence algorithms and hardware design architectures are optimized for synchronizing voice and data. And audio/video transmission quality; and it uses the world's smallest package, which can significantly reduce PCB layout area and simplify design resources.
At the same time, the exclusive Symphony software package from MediaTek also supports all advanced wireless link functions on the Android operating system. The Bluetooth software can provide up to 15 profiles covering most users' situations.
MediaTek is one of the few manufacturers in the industry to offer a four-in-one wireless link single chip for use in a variety of mobile communication terminals. The MT6628Q is fully compliant with the stringent requirements of mobile communication terminals for specifications and performance, including ultra-low power consumption to extend standby time. The small package is designed to meet the design of thin and light mobile phones, and is cost-effective to promote the popularity of WiFi-enabled wireless communication terminals.
The 4-in-1 wireless module technology threshold is quite high. Although Broadcom has successfully opened the distance from competitors with integrated chips, it has not been able to launch a 4-in-1 module that integrates GPS. The reason is that the GPS signal is quite weak, although the frequency and Wi- Fi, Bluetooth 2.4GHz is different, but requires a relatively high sensitivity to successfully receive GPS signals, the industry must also solve the problem of Wi-Fi, Bluetooth signal interference, and the interference of various technologies on the GPS signal, resulting in The difficulty of integration has improved a lot.
System block diagram
The S501 is based on MediaTek Inc.'s MT6628Q chip as the main core, and adds matching lines between WiFi and Bluetooth and GPS respectively, enabling WiFi to share a single antenna with Bluetooth and GPS, which can be used for antennas with insufficient space in smart phones. In addition, WiFi and Bluetooth and GPS independent antennas can be used, which are flexible and flexible.
The S501 needs to provide two sets of oscillation sources. One is the precise requirement for GPS. The TCXO (Temperature Compensate X'tal (crystal) Oscillator) temperature-compensated crystal oscillator has a frequency of 26MHz. The other is 32.768KHz for the back-end system. As a sleep state to wake up the S500M.
