ISPLSI 2032A-80LT44I

Complex Programmable Logic Devices Overview

The ispLSI 2032A-80LT44I is a high-density programmable logic device from the Lattice Semiconductor ispLSI 2000A family. It features 1000 PLD gates, 32 I/O pins, and 32 registers within a single Megablock architecture. Built on advanced 0.35-micron E2CMOS technology, it supports in-system programming via ISP with a maximum operating frequency of 84 MHz (fmax) and a propagation delay of 15 ns. The device operates at 5V, offers non-volatile reprogrammability, and includes three dedicated clock inputs and one global output enable pin.

Complex Programmable Logic Devices Procurement Notes

Verify product status as select devices in this series have been discontinued per Product Change Notification #09-10. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics. Ensure the LT44 suffix corresponds to the 44-pin TQFP package required for the specific PCB footprint.

Complex Programmable Logic Devices Selection Notes

Select the -80 speed grade for designs requiring an 84 MHz maximum toggle frequency. The LT44 suffix indicates a 44-pin Thin Quad Flat Package (TQFP). For industrial temperature ranges (-40°C to +85°C), ensure the 'I' suffix is included in the part number. Verify that the 5V supply voltage matches the system requirements, as the core is not 3.3V compatible.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2000A family, which enhances the original ispLSI 2000 series with 0.35-micron technology while maintaining form and function compatibility. The ispLSI 2032A serves as a direct upgrade to the ispLSI 2032, offering improved performance metrics and manufacturing yields while retaining the same pinout and logical structure.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2032E series is recommended for new designs due to enhanced features. Direct functional equivalents include the ispLSI 2032-80LT44I. Lead-free variants such as the ispLSI 2032A-80LTN44I are available for RoHS compliance.
