Wolfson Microelectronics has announced that applications processor vendor ZiiLABS has selected the WM8350 stereo CODEC with integrated power management for inclusion on both its ZMS-05 System Module for embedded devices and its Zii EGG StemCell Computer, the first market-ready handheld Plaszma platform.
The WM8350 is one of Wolfson's successful family of power management solutions, which are compatible with leading multimedia application processors. It features an integrated high fidelity audio CODEC and power management subsystem that delivers high performance audio and

extended battery life at a reduced system cost. Coupled with ZiiLABS' media-rich processortechnology, the WM8350 enables the creation of new and exciting high performance designs, whilst significantly

reducing power consumption, system cost, design challenges, manufacturing complexity and time-to-market. In the case of the WM8350, the savings can be up to 25 percent on the device bill of

materials (BOM) and up to 50 percent on the board footprint.



Wolfson is delighted to be working with ZiiLABS. The WM8350 provides

a highly integrated solution without compromising on audio

performance, a perfect fit for ZiiLABS' platforms and processors,

comments Jess Brown, power management product line manager at Wolfson.

Successful portable consumer electronics products are increasingly

differentiated through enhanced, high performance multimedia user

experiences, in ever smaller sizes with longer battery life. Working

with Wolfson offers processor vendors such as ZiiLABS the ideal

companion technology and an innovative product architecture optimised

to help the designer meet these demands.



The ZMS-05 is a fully programmable, media-rich applications processor

capable of delivering high performance HD video, 2D/3D graphics and

multimedia capabilities within a low power environment. The ZMS-05

System Module, incorporating the ZMS-05 and WM8350, comes in a

production-ready SODIMM form factor simplifying customer base board

developments. Based on the ZMS-05, the Zii EGG handheld StemCell

Computer, offers an energy efficient handheld platform featuring a

multi touch display, GPS, forward and rear facing cameras, Bluetooth,

HDMI, full size SD card slot, 256MB RAM, 16/32GB Flash Memory and Wi-Fi.



We have chosen the WM8350 because of Wolfson's world-class expertise

in audio and power management mixed-signal design. Wolfson has

provided excellent application support throughout the project,

something that has been an essential component in our decision to work

with them, comments Tim Lewis, Marketing Director at ZiiLABS. The

WM8350 and ZMS-05 processor form a powerful combination that will help

designers differentiate their products with media-rich applications at

the lowest possible power consumption. Both the WM8350 and ZiiLABS'

ZMS-05 are highly integrated devices that help shorten system design

times and reduce the requirement for additional components, whilst

delivering a superb, non-compromised multimedia experience.



The WM8350 functions include a high performance, low power audio CODEC

with advanced mixing capability that delivers excellent 98dB SNR

performance. The device also features on-chip clock generation, six DC-

DC converters, four LDO voltage regulators, a lithium battery charger,

two white LED drivers and an auxiliary analogue to digital converter

(ADC), all inside a compact 7x7mm BGA package.
