ISPLSI2096-80LQI

Overview

The ISPLSI2096-80LQI is an Electrically Erasable Programmable Logic Device (EE PLD) manufactured by Lattice Semiconductor. It features a propagation delay of 18.5 ns and supports a maximum clock frequency of 57 MHz. The device contains 96 macrocells and provides 96 I/O lines with 3 dedicated inputs. It operates at a nominal supply voltage of 3.3 V and is housed in a 128-pin Plastic Quad Flat Package (PQFP).

Feature Summary

• Contains 96 macrocells for complex logic implementation.
• Supports In-System Programming (ISP) for flexible updates.
• Features 96 I/O lines with 3 dedicated inputs.
• Operates within a commercial temperature range of 0°C to 70°C.

Applications

• Complex glue logic replacement in digital systems.
• Address decoding and bus interfacing.
• State machine implementation for control applications.

Procurement Notes

Verify the specific suffix 'LQI' against official Lattice documentation to confirm package type, lead finish, and temperature grade. Ensure compatibility with existing PCB footprints for the 128-pin PQFP package. Confirm that the design supports the required 3.3V operating voltage and ISP capabilities.

Selection Notes

Select this component when 96 macrocells are required with high pin count. Compare the 18.5 ns delay against system timing requirements. Consider the ISPLSI2096A series variants if different speed grades or lead-free compliance (e.g., LT128 suffix) are needed for the application.

Part Context

This part belongs to the ISPLSI2096 family of EE PLDs from Lattice Semiconductor. These devices are designed as drop-in replacements for GALs and PALs while offering higher density and reprogrammability. The family includes various speed grades and package options to suit different performance and form factor needs.

Replacement Considerations

Direct functional equivalents include other ISPLSI2096 variants such as ISPLSI2096-80LT128 or ISPLSI2096A-80LT128. Verify pinout compatibility and electrical characteristics before substitution. Check for lead-free status if environmental regulations require it.
