GAL20V8 is a high-performance E2CMOS PLD (programmable logic device) from Lattice Semiconductor Corp. It has a maximum propagation delay of 5 ns and a maximum operating frequency of 166 MHz. The device uses UltraMOS advanced CMOS technology, with power consumption 50% to 75% lower than that of bipolar devices. Typical current for low-power devices is 75mA, and typical current for quarter-power devices is 45mA. In addition, the device has active pull-ups on all pins, reconfigurable logic, reprogrammable cells, 100% tested / 100% yields, high-speed electrical erasure (<100ms), and 20-year data retention.
The GAL20V8 is a high‑performance E?CMOS programmable logic device featuring up to 5 ns maximum propagation delay, active pull‑ups on all pins, and reprogrammable cells with 20‑year data retention. It supports three global Output Logic Macrocell (OLMC) modes—simple, complex, and registered—and can emulate a wide range of PAL architectures.
The document provides detailed electrical characteristics, pin configurations for DIP and PLCC packages, timing tables for commercial and industrial grades, and mode‑specific configuration rules, including clock and output‑enable pin assignments.
| Maximum propagation delay (Tpd) | 5 ns |
