ISPLSI 2128VE-100LTN176

Complex Programmable Logic Devices Overview

The ispLSI 2128VE-100LTN176 is a high-density, in-system programmable logic device manufactured by Lattice Semiconductor. It features 6000 PLD gates, 128 macrocells, and 28 I/O pins within a 176-pin TQFP package. The device operates at a maximum frequency of 100 MHz with a typical propagation delay of 7.5 ns. It utilizes 3.3V E2CMOS technology for non-volatile reprogrammability via IEEE 1149.1 boundary scan. Key architectural elements include 32 Generic Logic Blocks (GLBs), three dedicated clock inputs, and eight dedicated input pins.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-100) matches the required 100 MHz operating frequency. Confirm the -LTN176 suffix corresponds to the lead-free 176-pin TQFP package. Check current availability status as this component may be subject to discontinuation notices from the manufacturer.

Complex Programmable Logic Devices Selection Notes

Select the -100 speed grade if the design requires a maximum operating frequency of 100 MHz. Ensure the 176-pin TQFP package fits the PCB footprint constraints. Consider the -250 variant if higher performance up to 250 MHz is needed, or the -135 variant for lower power consumption at 135 MHz.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2128VE family, which offers 100% functional and pinout compatibility with the older ispLSI 2128V devices. The VE series introduces enhanced performance through E2CMOS technology while maintaining the same logical structure and programming interface.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other speed grades within the same package, such as ispLSI 2128VE-135LTN176 or ispLSI 2128VE-250LTN176. For legacy compatibility, the non-V version ispLSI 2128V-100LTN176 is functionally equivalent but lacks the improved speed characteristics.
