ISPLSI 2064A-125LT100

Complex Programmable Logic Devices Overview

The Lattice Semiconductor ISPLSI2064A-125LT100 is a high-density, in-system programmable logic device (PLD) from the ispLSI 2000AFamily. It features 2000 PLD gates, 64 macro cells, and 64 I/O pins within a 100-pin TQFP package. Built on advanced 0.35 micron E2CMOS technology, it operates at a maximum frequency of 125 MHz with a propagation delay of 7.5 ns. The device supports non-volatile reprogramming, TTL-compatible inputs/outputs, and includes three dedicated clock pins and two global output enable pins for flexible system design.

Complex Programmable Logic Devices Feature Summary

• High Density Logic: Contains 2000 PLD gates, 64 macro cells, and 16 Generic Logic Blocks (GLBs).
• High Performance: Achieves fmax = 125 MHz and tpd = 7.5 ns using 0.35 micron E2CMOS technology.
• In-System Programmability: Supports ISP via 5V only, allowing reprogramming without removal from the PCB.
• Flexible I/O Configuration: Features 64 universal I/O pins, four dedicated inputs, and three dedicated clock inputs.

Complex Programmable Logic Devices Applications

• Complex glue logic replacement in digital systems.
• State machine implementation requiring fast global interconnect.
• Address decoding and counter applications utilizing wide input gating.
• Prototyping designs prior to ASIC or FPGA migration.

Complex Programmable Logic Devices Procurement Notes

Verify component status as select devices in this family have been discontinued per PCN #02-06. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics. Ensure lead-free packaging options are specified if required by assembly processes. Check moisture sensitivity levels for handling requirements.

Complex Programmable Logic Devices Selection Notes

Select the -125 speed grade for designs requiring 125 MHz operation and 7.5 ns propagation delay. Choose the LT100 suffix for the 100-pin Thin Quad Flat Package. Consider the LJN84 variant if an 84-pin PLCC form factor is needed instead. Verify voltage compatibility as the device requires a 5V supply with TTL-level signaling.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2000AFamily, which is fully form and function compatible with the earlier ispLSI 2064 series. The 'A' designation indicates enhancements via advanced 0.35 micron E2CMOS technology while maintaining identical timing specifications and packaging options compared to its predecessor.

Complex Programmable Logic Devices Replacement Considerations

For new designs, Lattice recommends using the ispLSI 2064E series. Direct functional replacements include other parts within the ispLSI 2064/A family with matching speed grades and package types, such as ISPLSI2064A-125LJ84 for PLCC packages.
