ISPLSI 2032A-80LJ44

Complex Programmable Logic Devices Overview

The ispLSI 2032A-80LJ44 is a high-density complex programmable logic device (CPLD) manufactured by Lattice Semiconductor. It features 1000 PLD gates, 32 universal I/O pins, two dedicated inputs, and three dedicated clock inputs. Built on advanced 0.35-micron E2CMOS technology, the device supports in-system programming with non-volatile EEPROM storage. The -80 speed grade provides a maximum operating frequency of 84 MHz and a typical propagation delay of 10.0 ns. It operates within a supply voltage range of 4.75V to 5.25V and utilizes a 44-pin PLCC package.

Complex Programmable Logic Devices Feature Summary

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required speed grade (-80) and package type (LJ44). Check for lead-free variants if environmental compliance is mandatory. Ensure design tools support the legacy ispLSI 2032A family for successful compilation and programming.

Complex Programmable Logic Devices Selection Notes

Select the ispLSI 2032A-80LJ44 when designs require up to 32 I/Os and moderate speed performance around 84 MHz. Compare against the -110 or -135 grades if higher frequencies are needed. Consider the -80LJN44 variant for lead-free assembly requirements. Verify that the 5V-only ISP capability aligns with system programming infrastructure constraints.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2000A family, which enhances the original ispLSI 2032 with improved density and performance while maintaining form and function compatibility. The 2032A series represents a transition point in Lattice's CPLD portfolio, utilizing 0.35-micron technology before subsequent generations introduced lower voltage options.

Complex Programmable Logic Devices Replacement Considerations

The datasheet explicitly recommends using the ispLSI 2032E for new designs. Direct pin-to-pin replacements within the same package may include other speed grades like the ispLSI 2032A-110LJ44, provided timing requirements are met. No alternative part numbers are listed as direct functional substitutes in the provided documentation.
