ISPLSI 1016-60LT44

Complex Programmable Logic Devices Overview

The ispLSI 1016-60LT44 is a discontinued high-density programmable logic device from Lattice Semiconductor, manufactured in a 44-pin Thin Quad Flat Package (TQFP). It utilizes E2CMOS technology for non-volatile reprogrammability and supports 5-Volt in-system programming. The device architecture comprises 16 Generic Logic Blocks (GLBs), providing 96 registers, 32 universal I/O pins, four dedicated inputs, and three dedicated clock inputs. Key electrical specifications include a maximum operating frequency of 60 MHz and a propagation delay of 20 ns.

Complex Programmable Logic Devices Feature Summary

• High-density architecture with 2000 PLD gates and 96 registers
• Non-volatile E2CMOS technology enabling in-system reprogramming
• Global Routing Pool (GRP) for complete interconnectivity between logic elements
• Three dedicated clock input pins with flexible clock distribution network

Complex Programmable Logic Devices Applications

• Replacement for complex glue logic in digital systems
• Implementation of state machines and address decoders
• Construction of wide-input gating for counters
• Field-programmable structured designs requiring reconfigurability

Complex Programmable Logic Devices Procurement Notes

All devices in the ispLSI 1016 family are officially discontinued as per Product Change Notification PCN#05A-10. No new production units are available from Lattice Semiconductor. Verification of component authenticity is critical when sourcing from secondary markets due to the long-standing end-of-life status.

Complex Programmable Logic Devices Selection Notes

Designers should evaluate modern Lattice FPGA or CPLD families for new projects, as the ispLSI series is obsolete. The -60 speed grade specifies a 60 MHz maximum frequency and 20 ns propagation delay. Ensure replacement components support the required 5V supply voltage and TQFP-44 footprint if maintaining legacy board layouts.

Complex Programmable Logic Devices Part Context

The ispLSI 1016 belongs to the first generation of in-system programmable high-density PLDs offering non-volatile logic and interconnect reconfiguration. It was designed to combine the ease of use of PLDs with the density of FPGAs. The LT44 suffix specifically denotes the commercial grade variant housed in a 44-pin TQFP package.
