Programmable Logic Device Pld Procurement Notes

Verify the specific suffix QJ corresponds to the 20-pin PLCC package configuration. Confirm that the 3.3V operating voltage aligns with system power requirements, as this variant differs from standard 5V versions. Ensure design tools support the E2CMOS technology for proper programming and erasure cycles. Check for lead-free compliance status if required by project specifications.

Programmable Logic Device Pld Selection Notes

Select this component when a reprogrammable alternative to fixed gate arrays is needed without increasing power consumption. The 3.3V interface allows integration into mixed-voltage systems alongside 5V TTL components. Consider the 15ns delay for timing-critical paths requiring moderate speed. The zero-power feature makes it suitable for applications where standby current reduction is a priority over raw performance metrics.

Programmable Logic Device Pld Part Context

This part belongs to the GAL16V8 family of Simple Programmable Logic Devices (SPLDs). It utilizes Electrically Erasable CMOS technology, distinguishing it from traditional fuse-based PLDs. The series offers flexibility for prototyping and final production runs due to its reprogrammability. Lattice Semiconductor positions these devices as cost-effective solutions for replacing discrete logic gates in embedded designs.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements within the same family include GAL16V8D-15QJ for standard voltage applications. For lower power variants, consider GAL16LV8ZD-15QI or GAL16LV8ZD-15QNI depending on the package type. Verify that the replacement maintains the 20-pin PLCC footprint and compatible logic function mapping.
