Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix '100' corresponds to the 100 MHz fmax requirement. Confirm the 'LJ' suffix indicates the standard lead-based 100-pin TQFP package; for lead-free requirements, select the 'LTN' or 'LJN' variants. Ensure the design environment supports the ispLSI architecture, as the datasheet recommends the ispLSI 1032EA for new designs.

Complex Programmable Logic Devices Selection Notes

Select this component when a non-volatile, reprogrammable solution with high I/O density is required. The 100LJ variant provides a 7.5 ns tpd suitable for moderate-speed synchronous designs. Consider the ispLSI 1032EA if enhanced features or newer manufacturing processes are preferred for new projects. Verify power consumption estimates based on the number of active product terms and nets.

Complex Programmable Logic Devices Part Context

The ispLSI 1032E belongs to Lattice's high-density PLD family, bridging the gap between simple CPLDs and FPGAs. It offers the ease of use of PLDs with the flexibility of structured FPGA-like interconnects via the Global Routing Pool. This specific part is a functional superset of the earlier ispLSI 1032, adding global output enable pins for improved system control.

Complex Programmable Logic Devices Replacement Considerations

The datasheet explicitly advises using the ispLSI 1032EA for new designs. Direct pin-compatible replacements within the same speed grade and package are limited within the immediate family without verifying electrical parameter compatibility.
