Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-100) matches the required 100 MHz performance specification. Confirm the LT176 package designation corresponds to the 176-pin Thin Quad Flat Package. Ensure design tools support the E2CMOS technology for programming and verification.

Complex Programmable Logic Devices Selection Notes

Select this component when 6000 gate density and 128 I/Os are required. The -100 speed grade is suitable for applications needing 100 MHz operation. Choose between 3.3V or 5V I/O configurations based on system voltage requirements. The 176-pin TQFP package is appropriate for surface-mount assembly.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2128E family, which offers upward compatibility with the earlier ispLSI 2128 devices. It is designed to combine the ease of use of PLDs with the flexibility of FPGAs. The device provides non-volatile reprogrammability and supports both synchronous and asynchronous clocking schemes.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2128E-100LT176 is functionally compatible with the ispLSI 2128 series. Designers migrating from older PLDs should verify pin locking capabilities and timing constraints. No direct cross-model substitutes are listed in the provided documentation.
