Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'LT44' corresponds to the 44-pin TQFP package configuration. Confirm whether the component requires commercial or industrial temperature grade designation based on system requirements. Check current product status as some devices in this family have been discontinued; consult official documentation for availability and potential obsolescence notices before procurement.

Complex Programmable Logic Devices Selection Notes

Select the ispLSI 2032A-150LT44 when designs require 1000 PLD gates with a 10 ns propagation delay. Ensure the application utilizes a 5V supply voltage compatible with TTL levels. Consider the 44-pin TQFP package constraints for PCB layout. Verify that the design fits within the 32 macrocell capacity and utilizes the available dedicated clock and input resources effectively.

Complex Programmable Logic Devices Part Context

The ispLSI 2032A series represents an enhancement over the original ispLSI 2032, maintaining full form and function compatibility while leveraging advanced 0.35-micron E2CMOS technology. This generation offers improved performance metrics and manufacturing yields. The device is part of the ispLSI 2000 family, designed to bridge the gap between simple PLDs and complex FPGAs, offering field-programmable flexibility with PLD-like speed.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2032E is recommended for new designs instead of the ispLSI 2032A series. The ispLSI 2032A is fully form and function compatible with the original ispLSI 2032, allowing for direct pin-for-pin substitution if upgrading from the earlier version. Verify timing specifications match when replacing with other speed grades in the same package.
