GAL16V8D-20QPNI

Programmable Logic Device Pld Overview

The GAL16V8D-20QPNI is a discontinued high-performance E2CMOS PLD from the GAL16V8 series by Lattice Semiconductor. It features an 8-macrocell architecture with 16 inputs and 8 outputs in a 20-pin DIP package. The device supports registered, complex, and simple logic modes with a maximum propagation delay of 20 ns and a typical operating current of 45 mA for quarter-power variants. It utilizes Electrically Erasable floating gate technology allowing reprogramming and includes features like active pull-ups and register preload.

Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued by Lattice Semiconductor per Product Change Notification (PCN). No new units are manufactured or supplied by the original equipment manufacturer. Verification of availability should focus on third-party surplus distributors or alternative replacement components rather than direct procurement channels.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with specific PAL fuse maps or existing GAL16V8 designs is required. Note that the 'Q' suffix indicates Quarter Power consumption (approx. 45 mA typical), while 'I' denotes Industrial temperature range (-40°C to 85°C). Ensure design tools support the GAL16V8 device type for proper OLMC configuration.

Programmable Logic Device Pld Part Context

The GAL16V8D-20QPNI belongs to the GAL16V8 family, which emulates various 20-pin PAL architectures. The 'D' suffix specifies the High Performance E2CMOS process variant. This specific ordering code combines the industrial grade ('I'), quarter power consumption ('Q'), and plastic DIP packaging ('PN').

Programmable Logic Device Pld Replacement Considerations

As the device is discontinued, consider modern SPLD alternatives or low-power FPGAs from Lattice such as the MachXO series or iCE40 series for new designs. Verify pinout and logic density compatibility when migrating from the GAL16V8 architecture.
