PZ3960N

PZ3960N Technical Summary

Overview

The PZ3960N is a high-density SRAM-based Complex Programmable Logic Device (CPLD) from Philips Semiconductors, belonging to the CoolRunner® family. It is designed to deliver high-speed performance with deterministic pin-to-pin timing while maintaining low power consumption. The device leverages the patented Fast Zero Power (FZP) design technique, which enables it to achieve true pin-to-pin timing delays of 7.5ns and standby currents as low as 100 microamps without relying on power-down schemes like 'turbo bits.' By utilizing a cascaded chain of pure CMOS gates instead of conventional sense amplifier methods, the PZ3960N significantly reduces both standby and dynamic power consumption compared to competing CPLDs.
