Serial Flash is ideal match for FPGA applications
NexFlash spiFlash serial Flash memories have been qualified for use with Xilinx's new SpartanT-3E field-programmable gate array (FPGA) family.
The W684386 also delivers the industry's best idle channel noise and return loss performance - benchmarks which VoIP-system makers are making a priority to reduce.
Optimised for short-loop applications, the W684386 targets the VoIP equipment market, including products such as high-density VoIP gateways, analogue telephone adapters, voice-enabled DSL and cable modems, IP-PBX, FTTX systems and set-top boxes.
"As port densities on VoIP equipment increase dramatically with each generation, system designers are looking for a flexible solution with excellent price and performance benchmarks", says Ike Saeed, Vice President of Marketing of Winbond's Mixed Signal Product Centre.

Serial Flash boasts fastest interface
Quad-SPI architecture allows for greater than six times the performance of the current generation of serial Flash memories and offers a true code-execution alternative to parallel-NOR Flash.
"The W684386 fills this need with a robust four-channel design that not only reduces system cost but also improves the clarity of the VoIP signals".
The W684386 leverages Winbond's proprietary codec/SLCC architecture, combining four programmable codecs that enable the device to support a comprehensive set of signalling capabilities for telephone line supervision and control, offload processor overhead and offer designers a user-friendly signal-processing environment.
The W684386's four-channel SLCC block supports programmable impedance matching and trans-hybrid balancing ensuring that worldwide compliance can be supported from a single hardware configuration.
The W684386 also incorporates programmable DC/DC controllers, which allow power consumption optimisation on a per channel basis.
The device can also support higher-density architectures with external ringing and centralised power options.
Winbond's proprietary codec/SLCC is protected by US Patent 7,260,212 issued on 21st August 2007.
The W684386 is available now in a 128-QFP package, at US $4.50 (10,000-unit quantities), with full production scheduled for Q2.
Three evaluation boards are available, each featuring a different DC/DC architecture option (per-channel inductor-based, single transformer-based or external battery/external ringing architecture).
Each evaluation board features Winbond's user-friendly PC-based graphical user interface.
Samples and evaluation boards are available now from local Winbond sales offices and the company's authorised representatives.
