GAL16V8D-15LJN

Programmable Logic Device Pld Overview

The GAL16V8D-15LJN is a discontinued Simple Programmable Logic Device (SPLD) manufactured by Lattice Semiconductor. It utilizes high-performance E2CMOS technology to provide a maximum propagation delay of 15 ns and a maximum operating frequency of 45.5 MHz. The device features an electrically erasable floating gate architecture, allowing for reprogrammability with over 100 erase/write cycles and data retention exceeding 20 years. It contains eight output logic macrocells (OLMCs) capable of emulating various PAL architectures through configurable modes. The component is housed in a 20-pin Plastic Leadless Chip Carrier (PLCC) package.

Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued by Lattice Semiconductor pursuant to Product Change Notification PCN#13-10. No new units are available from the manufacturer or authorized distributors. Verification of availability should be restricted to secondary market sources or inventory held by third-party suppliers.

Programmable Logic Device Pld Selection Notes

Designers requiring this specific logic density and speed should note that the GAL16V8D-15LJN is obsolete. Selection of replacement components must account for the transition from legacy PLD technology to modern FPGA or CPLD solutions. Compatibility checks for pinout and logic emulation capabilities are required when migrating existing designs.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents a generation of generic array logic devices designed to replace discrete bipolar logic gates. The 'D' suffix indicates the use of E2CMOS technology, distinguishing it from earlier non-erasable versions. This family was widely used for system integration before the prevalence of complex programmable logic devices.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation due to the discontinuation status. Designers should consult current Lattice product portfolios for modern equivalents.
