ISPLSI 2032A-180LTN44

Complex Programmable Logic Devices Overview

The ispLSI 2032A-180LTN44 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 within a lead-free 44-pin Thin Quad Flat Package (TQFP). Built on advanced 0.35-micron E²CMOS technology, the device supports in-system programming via ISP™ with a maximum operating frequency of 180 MHz and a typical propagation delay of 5.0 ns. It operates on a 5V supply voltage range of 4.75V to 5.25V.

Complex Programmable Logic Devices Feature Summary

• High Density Logic: Contains 1000 PLD gates organized into eight Generic Logic Blocks (GLBs) with 32 registers and a Global Routing Pool for complete interconnectivity.
• High Performance: Achieves a maximum operating frequency of 180 MHz with a typical propagation delay of 5.0 ns using 0.35 micron E²CMOS technology.
• In-System Programmability: Supports non-volatile, electrically erasable reprogramming via ISP™ at 5V, allowing for field updates and reduced prototyping time.
• Flexible I/O Configuration: Features 32 I/O pins with individually programmable slew rates to minimize switching noise, plus dedicated clock and input pins.

Complex Programmable Logic Devices Applications

• Address decoding and bus bridging in embedded systems
• State machine implementation for industrial control
• Fast counter applications requiring wide input gating
• Glue logic replacement in mixed-signal designs

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and lead-free compliance upon receipt. Check for discontinuation notices as some variants may be obsolete; consult official ordering guides for current availability status before finalizing procurement plans.

Complex Programmable Logic Devices Selection Notes

Select the -180 speed grade for designs requiring up to 180 MHz operation. Ensure the design fits within the 1000 gate limit and 32 register capacity. Verify that the 5V I/O voltage levels match system requirements, as the device is not inherently 3.3V tolerant without specific configuration. Consider the TQFP-44 package dimensions for PCB layout constraints.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2000A family, which offers form and function compatibility with the original ispLSI 2032 series while utilizing improved 0.35-micron technology. The 'LTN' suffix indicates a lead-free 44-pin TQFP package, distinguishing it from standard plastic or PLCC variants within the same electrical specification group.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2032E series is recommended for new designs due to enhanced performance features. Direct pin-compatible replacements within the same family include other speed grades like the ispLSI 2032A-150LTN44, provided timing requirements are relaxed accordingly.
