ISPLSI 2128VE-100LB208

Complex Programmable Logic Devices Overview

The ispLSI 2128VE-100LB208 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 100-pin TQFP package. The device operates at a supply voltage of 3.3V with a maximum operating frequency of 135 MHz and a propagation delay of 4 ns. It utilizes E2CMOS technology for non-volatile reprogrammability and includes three dedicated clock inputs, eight dedicated input pins, and full IEEE 1149.1 boundary scan testability.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific speed grade suffix matches design timing requirements. Check for lead-free packaging compliance if required by assembly standards. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells and 28 I/Os are sufficient for the design. The -100 speed grade provides a 4 ns propagation delay suitable for moderate-speed applications. Consider the -250 variant if higher frequencies up to 250 MHz are required. Ensure the 100-pin TQFP package fits the PCB footprint constraints.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2128VE family, which offers 100% functional and pinout compatibility with the older ispLSI 2128V series. The VE series introduces enhanced performance and lower voltage operation while maintaining architectural similarities. It serves as a bridge between traditional PLDs and FPGAs, offering density with ease of use.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other variants within the ispLSI 2128VE family, such as the -135 or -250 speed grades, provided package and I/O counts match. The legacy ispLSI 2128V is functionally compatible but lacks the improved speed and voltage specifications of the VE series.
