ISPLSI 2032A-180LTN48

Complex Programmable Logic Devices Overview

The ispLSI 2032A-180LTN48 is a high-density, in-system programmable logic device (PLD) manufactured by Lattice Semiconductor. It utilizes advanced 0.35-micron E2CMOS technology to deliver a maximum operating frequency of 180 MHz with a propagation delay of 5.0 ns. The component features 1000 PLD gates, 32 universal I/O pins, two dedicated inputs, and 32 registers organized into eight Generic Logic Blocks (GLBs). It supports non-volatile reprogrammability via ISP at 5V, includes three dedicated clock pins, and offers programmable output slew rate control for noise reduction.

Complex Programmable Logic Devices Feature Summary

• Non-volatile EEPROM architecture allowing electrically erasable and reprogrammable logic
• In-System Programmability (ISP) enabling field updates without removal from the board
• Flexible pin placement and enhanced pin locking capabilities within a 48-pin TQFP package

Complex Programmable Logic Devices Applications

• Address decoding and bus interface logic
• State machine implementation
• Fast counter circuits
• Glue logic replacement in digital systems

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lead-free status as indicated by the 'N' suffix in the part number. Check current product lifecycle status, as specific speed grades within this family may have discontinuation notices. Ensure programming equipment supports the ISP protocol for functional verification upon receipt.

Complex Programmable Logic Devices Selection Notes

Select the -180 speed grade when designs require a maximum operating frequency of 180 MHz. The LT48 suffix indicates a 48-pin Thin Quad Flat Package (TQFP); verify footprint compatibility against the datasheet pinout diagram. This device operates strictly at 5V; ensure system voltage levels match the recommended operating conditions. Consider the ispLSI 2032E series for new designs if higher performance or mixed-voltage I/O support is required.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2032/A family, which serves as an enhancement over the original ispLSI 2032 using 0.35-micron technology. It maintains form and function compatibility with previous generations while offering improved manufacturing yields. The device represents a bridge between traditional PLDs and FPGAs, combining ease of use with high density.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2032E series is functionally upward compatible and recommended for new designs. Verify that any substitute device matches the 48-pin TQFP package dimensions and pin configuration to ensure mechanical interchangeability.
