Migration to 90nm 5V Async SRAMs

Cypress started qualifying its 90nm technology asynchronous SRAMs in early 2006. These products, offered in 1.8V, 3.3V and 5V ranges, have best-in-class specs and are form-, fit- and functionally compatible with the older technology products (130nm technology and earlier). They are drop-in replacements for the existing devices and there would be no application issues when migrating from the older generation products. Hence, Cypress strongly encourages its customers to migrate to 90nm technology products. This application note discusses the migration of 5V asynchronous SRAMs from existing technology (250nm and earlier) to 90nm technology.
