Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-80) corresponds to the required 84 MHz maximum frequency and 10-15 ns propagation delay. Confirm the LT44 suffix indicates the 44-pin Thin Quad Flat Package (TQFP). Check current product status as some variants in this family may be discontinued; consult official ordering information for availability.

Complex Programmable Logic Devices Selection Notes

Select the ispLSI 2032A-80LT44 when 1000 PLD gates and 32 I/Os are sufficient for the design. Ensure the system voltage is 5V, as this device uses a 5V programmable logic core. Consider the -80 speed grade if the application requires a maximum toggle frequency around 84 MHz. For new designs, verify if the ispLSI 2032E series is recommended instead.

Complex Programmable Logic Devices Part Context

The ispLSI 2032A is an enhanced version of the ispLSI 2032, built on 0.35-micron technology while maintaining form and function compatibility. It belongs to the ispLSI 2000A family of high-density PLDs. The 'LT44' designation specifically refers to the commercial grade 44-pin TQFP package variant.

Complex Programmable Logic Devices Replacement Considerations

The datasheet explicitly recommends using the ispLSI 2032E for new designs. The original ispLSI 2032 is fully compatible but lacks the 0.35-micron enhancement. Discontinued parts in this family may require checking with Rochester Electronics for inventory.
