ISPLSI 1032-60LTI

Complex Programmable Logic Devices Overview

The ISPLSI 1032-60LTI is a discontinued high-density programmable logic device from Lattice Semiconductor. It utilizes non-volatile E2CMOS technology and supports in-system programming at 5 volts. The device features 6000 PLD gates, 192 registers, 64 universal I/O pins, eight dedicated inputs, and four dedicated clock inputs. Key electrical parameters include a maximum operating frequency of 60 MHz for industrial applications, a typical propagation delay of 12 ns, and a supply voltage range of 4.75 V to 5.5 V. It is housed in a 100-pin Thin Quad Flat Package (TQFP).

Complex Programmable Logic Devices Feature Summary

• High-density architecture with 6000 PLD gates, 32 Generic Logic Blocks (GLBs), and 192 registers.
• Non-volatile E2CMOS technology enabling electrically erasable and reprogrammable logic without power cycling.
• In-system programming capability via serial interface (ispEN, SDI, SDO, SCLK) for 5V operation.
• Global Routing Pool (GRP) providing complete interconnectivity between GLBs, I/O cells, and dedicated inputs.

Complex Programmable Logic Devices Applications

• Complex glue logic replacement in digital systems.
• State machine implementation requiring fast random logic.
• Address decoding and counter circuits utilizing wide input gating.
• Prototyping designs due to in-system reprogrammability.

Complex Programmable Logic Devices Procurement Notes

All devices in the ispLSI 1032 family are officially discontinued by Lattice Semiconductor. Product Change Notifications (PCNs) confirm this status. Verification of component authenticity and physical condition is critical when sourcing from secondary markets, as original manufacturing has ceased.

Complex Programmable Logic Devices Selection Notes

This specific part number denotes the Industrial grade (-40°C to +85°C) with a 60 MHz speed bin in a 100-pin TQFP package. Designers should verify that the 5V supply requirement and TTL-compatible I/O levels match the target system interfaces. Consider modern replacements if new production is required, as this component is no longer in active production.

Complex Programmable Logic Devices Part Context

The ISPLSI 1032-60LTI belongs to the ispLSI 1032 family, which represents Lattice's high-density EE PLD line prior to the transition to more advanced CPLD architectures. It was designed to combine the ease of use of PLDs with the density of FPGAs, featuring a unique Global Routing Pool for flexible signal distribution across its 32 logic blocks.

Complex Programmable Logic Devices Replacement Considerations

Public datasheets list the ISPLSI 1032-60LJI (PLCC package) and ISPLSI 1032-60LT (Commercial TQFP) as related variants within the same discontinued family. No active cross-model substitutes are confirmed in the provided documentation; migration to newer Lattice ispMACH or CrossLink families is recommended for new designs.
