Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-180) matches the required 180 MHz performance specification. Confirm the package type (LT128 indicates 128-pin TQFP) aligns with board layout requirements. Ensure the industrial temperature grade (I) is suitable for the intended operating environment range of -40°C to +85°C.

Complex Programmable Logic Devices Selection Notes

Select this model when pinout compatibility with the legacy ispLSI 2096V/2096VE series is required but higher density is needed. Consider the -225 speed grade if designs demand lower propagation delays (4.0 ns). Evaluate power consumption estimates based on active product terms and switching frequency using the provided ICC equation.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2000VE family of SuperFAST PLDs. It serves as a bridge between traditional PLDs and FPGAs, offering FPGA-like density with PLD ease of use. The device is designed for applications needing rapid prototyping and field updates through its in-system programmable architecture.

Complex Programmable Logic Devices Replacement Considerations
