Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific -150 speed grade and LT48 package variant matches design requirements. Check for lead-free packaging options if environmental compliance is necessary. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Complex Programmable Logic Devices Selection Notes

Select this model when 1000 PLD gates and 32 I/Os are required with 5V operation. The -150 grade provides 154 MHz performance suitable for moderate-speed synchronous designs. Compare against ispLSI 2032E for new designs as recommended by the manufacturer. Consider pin compatibility with the original ispLSI 2032 series if upgrading existing boards.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2000A family, which enhances the original ispLSI 2032 with 0.35 micron technology while maintaining form and function compatibility. It sits between the -135 and -180 speed grades in terms of performance characteristics. The LT48 suffix denotes the 48-lead Thin Quad Flat Package configuration.

Complex Programmable Logic Devices Replacement Considerations

The datasheet recommends using ispLSI 2032E for new designs. Direct functional replacements include other ispLSI 2032A variants with compatible timing specifications. Verify pinout compatibility when substituting with different speed grades or package types within the same family.
