Complex Programmable Logic Devices Procurement Notes

Verify component authenticity and physical condition upon receipt. Confirm the part number matches the specific speed grade (-80) and package type (TQFP-176). Check for lead-free markings if required by environmental standards. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring high pin count and moderate speed within a dense PLD architecture. The -80 speed grade provides an 81 MHz operating frequency suitable for many synchronous applications. Ensure the design accommodates the 5V power supply requirement and utilizes the available dedicated clock inputs for optimal timing performance.

Complex Programmable Logic Devices Part Context

This device belongs to the ispLSI 2128/A family, which offers form and function compatibility with the original ispLSI 2128 but incorporates advanced 0.35 micron technology. The 'A' suffix denotes these enhancements while maintaining identical timing specifications and packaging options as the predecessor series.

Complex Programmable Logic Devices Replacement Considerations

Lattice recommends using the ispLSI 2128E for new designs instead of the 2128A series. Verify if legacy inventory from Rochester Electronics is available if direct replacement is necessary.
