Reduce Total System Cost in Portable Applications Using Zero-Power CPLDs

Traditionally, portable system designers have used ASICs and ASSPs to implement memory interfaces, I/O expansion, power-on sequencing, discrete logic functions, display, and other functions in portable systems. Cost limitations, power and cooling restrictions, and board space requirements often limit the use of programmable logic devices in these applications. Today, however, innovations in CPLDs in power reduction, cost optimization, and small form-factor packaging allow programmable logic devices to replace or augment ASICs, ASSPs, and discrete devices in portable applications.
