ISPLSI 2096VE-135LT128I

Complex Programmable Logic Devices Overview

The ispLSI 2096VE-135LT128I is a high-density, 3.3V in-system programmable logic device manufactured by Lattice Semiconductor. It features 4000 PLD gates, 96 I/O pins, and 96 registers organized into 24 Generic Logic Blocks (GLBs). The -135 speed grade provides a maximum operating frequency of 135 MHz with a typical propagation delay of 7.5 ns. Packaged in a lead-free 128-pin TQFP, it supports IEEE 1149.1 boundary scan testing and offers open-drain output options for flexible bus interfacing.

Complex Programmable Logic Devices Feature Summary

• High-performance E²CMOS technology with 135 MHz max frequency and 7.5 ns propagation delay
• In-system programmability via Boundary Scan Test Access Port (TAP)
• 96 I/O pins with individually programmable open-drain or totem-pole outputs
• Three dedicated clock input pins and two dedicated global OE pins

Complex Programmable Logic Devices Applications

• Complex state machine implementations
• Address decoding and wide input gating applications
• Bus arbitration and wired-OR logic interfaces
• Mixed-voltage system interfacing with standard 5V TTL devices

Complex Programmable Logic Devices Procurement Notes

Verify the ordering suffix LT128I corresponds to the Industrial temperature range (-40°C to +85°C) and Lead-Free 128-Pin TQFP package. Confirm that the -135 speed grade meets the specific timing requirements of the target design, as faster grades like -250 are recommended for new designs.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring high density with low power consumption due to unused product term shutdown. Ensure the design utilizes the Global Routing Pool for interconnectivity. Consider the -250 grade if higher performance is needed, as it is specified for new designs.

Complex Programmable Logic Devices Part Context

This device belongs to the ispLSI 2096VE family, which is functionally and pinout compatible with the older ispLSI 2096V series. It serves as a drop-in replacement for legacy designs while offering enhanced features like in-system programmability and lower voltage operation.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements include other speed grades within the same package, such as ispLSI 2096VE-200LT128I or ispLSI 2096VE-250LT128I. For lead-free commercial variants, consider ispLSI 2096VE-135LTN128.
