Overview

The CoolRunner XPLA3 (eXtended Programmable Logic Array) family of CPLDs is targeted for low power systems that include portable, handheld, and power sensitive applications. Each member of the CoolRunner XPLA3 family includes Fast Zero Power (FZP) design technology that combines low power and high speed. With this design technique, the CoolRunner XPLA3 family offers true pin-to-pin speeds of 5.0 ns, while simultaneously delivering power that is less than 56 μW at standby without the need for "turbo bits" or other power down schemes. By replacing conventional sense amplifier methods for implementing product terms (a technique that has been used in PLDs since the bipolar era) with a cascaded chain of pure CMOS gates, the dynamic power is also substantially lower than any other CPLD. CoolRunner devices are the only TotalCMOS PLDs, as they use both a CMOS process technology and the patented full CMOS FZP design technique. The FZP design technique combines fast nonvolatile memory cells with ultra-low power SRAM shadow memory to deliver the industry’s lowest power 3.3V CPLD family.
