ISPLSI2096-125LQ

Overview

The ISPLSI2096-125LQ is an Electrically Erasable Programmable Logic Device (EE PLD) manufactured by Lattice Semiconductor. It features a 128-pin Plastic Quad Flat Package (PQFP) with a maximum propagation delay of 12.5 ns and a maximum clock frequency of 80 MHz. The device contains 96 macrocells, 3 dedicated inputs, and 96 I/O lines. It operates at a nominal supply voltage of 3.3 V and supports In-System Programming (ISP). The architecture utilizes CMOS technology for low power consumption.

Feature Summary

• 96 Macrocells with 3 dedicated inputs and 96 I/Os
• Maximum propagation delay of 12.5 ns
• Supports In-System Programming (ISP)
• 128-pin PQFP package

Applications

• Complex logic replacement in industrial control systems
• Address decoding and bus interfacing
• State machine implementation in communication protocols

Procurement Notes

Verify the specific speed grade suffix (e.g., -125) against official Lattice documentation to confirm the 12.5 ns timing specification. Ensure the package type matches the required 128-pin PQFP form factor. Confirm RoHS compliance status as legacy variants may differ from current production runs.

Selection Notes

Select this component when a high-density PLD with 96 macrocells is required for designs needing 3.3V operation and ISP capabilities. Compare the 12.5 ns delay against system timing requirements. Consider pin count compatibility if replacing older CPLD designs in existing PCB footprints.

Part Context

This part belongs to the ispLSI 2000V family of EE PLDs. It serves as a high-performance alternative to traditional gate arrays, offering non-volatile configuration and reprogrammability. The family is designed for applications requiring moderate logic density with fast signal propagation.

Replacement Considerations

Direct pin-to-pin replacements within the same family include ISPLSI2096-100LQ (faster speed) or ISPLSI2096-150LQ (slower speed). Verify electrical characteristics and timing constraints before substituting.
