ISPLSI 1016-80LT44

Complex Programmable Logic Devices Overview

The ispLSI 1016-80LT44 is a discontinued high-density programmable logic device (PLD) from Lattice Semiconductor, housed in a 44-pin Thin Quad Flat Package (TQFP). It utilizes non-volatile E2CMOS technology and supports 5-Volt in-system programming. The device architecture comprises 16 Generic Logic Blocks (GLBs), providing 96 registers and 32 universal I/O pins alongside four dedicated inputs. Key electrical specifications include a maximum operating frequency of 80 MHz and a worst-case propagation delay of 15 ns under commercial temperature conditions.

Complex Programmable Logic Devices Procurement Notes

All devices in the ispLSI 1016 family are officially discontinued. Product Change Notifications (PCNs #13-10 and #05A-10) confirm that manufacturing has ceased. Verification of current product status should reference these PCNs rather than standard distributor availability lists.

Complex Programmable Logic Devices Selection Notes

This specific part number denotes the -80 speed grade (80 MHz fmax) in a TQFP package. Designers requiring higher performance should consider the -60 or -110 variants if timing permits, though all remain discontinued. Industrial (-I) and Military (/883) grades offer different temperature ranges but share identical logical functionality.

Complex Programmable Logic Devices Part Context

The ispLSI 1016 represents an early generation of in-system programmable PLDs from Lattice Semiconductor. It bridges the gap between simple GALs and complex FPGAs by offering field-reprogrammable logic density. The device was widely used before the industry shifted toward FPGA-centric architectures.

Complex Programmable Logic Devices Replacement Considerations

Public confirmed substitute part numbers: None. The datasheet explicitly states all devices are discontinued without listing direct functional replacements within the same series.
