“As mobile devices grow in complexity, designers are hard pressed to pack additional functionality and intelligence into smaller footprints,” said QuickLogic’s senior solutions marketing manager, Howard Li. “By delivering our ArcticLink CSSP platform in WLCSP form, we allow handset OEMs and ODMs to address all their connectivity needs in the smallest possible area.”
ArcticLink is part of QuickLogic’s Customer Specific Standard Product (CSSP) offering. It combines hard-wired building blocks such as Hi-Speed USB 2.0 On-The-Go, SD, SDIO, MMC and CE-ATA, with an ultra-low power programmable fabric for implementing custom functions.
QuickLogic customises the fabric, usually in a matter of days or weeks. Fabricating the CSSP then requires only electrical programming of a stock wafer.
WLCSP eliminates the area overhead of conventional BGA packaging. It is achieved with a standard die by fabricating an additional metal redistribution layer to re-route the I/O lines from the perimeter bonding pads to an array. It then 'bumps' (adds solder balls to) the array, making it ready for customers to use in conventional surface-mount fabrication processes.
