ISPLSI81080V-60LB272I

Overview

The ISPLSI81080V-60LB272I is a complex programmable logic device (CPLD) from Lattice Semiconductor's ispLSI 8000 family. It features 8,192 usable macrocells and supports up to 272 general-purpose I/Os. The device operates with a maximum propagation delay of 60 ns and requires a 3.3 V supply voltage. It utilizes non-volatile in-system programmable Flash technology, allowing for unlimited reprogramming without removal from the circuit. The component is housed in a 272-pin FineLine BGA package.

Feature Summary

• 8,192 macrocells with high-density architecture
• Up to 272 user I/O pins for extensive connectivity
• Non-volatile Flash memory enabling infinite reprogrammability
• Supports in-system programming (ISP) via JTAG or dedicated pins

Applications

• High-density system control and interface bridging
• Complex glue logic replacement in industrial equipment
• Address decoding and bus arbitration in computing systems
• Protocol conversion between legacy and modern interfaces

Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to confirm temperature range and package variant. Ensure that the ordering information matches the exact speed grade and pinout requirements for the target design. Cross-reference part numbers with official distributor catalogs to avoid obsolete stock.

Selection Notes

Select this model when designs require a large number of macrocells and I/Os within a single CPLD solution. Compare against smaller density devices if fewer resources are sufficient to reduce cost. Consider the 60 ns speed grade relative to system clock requirements. Evaluate package availability for the 272-pin BGA form factor during initial design phases.

Part Context

This component belongs to the ispLSI 8000 series, representing a high-performance generation of CPLDs. It succeeds earlier GAL-based architectures by offering significantly higher density and non-volatile configuration storage. The series is designed for applications demanding robust logic capacity and flexible I/O configurations without the complexity of FPGA development flows.

Replacement Considerations

Direct replacements include other members of the ispLSI 8000 family with equivalent or higher macrocell counts. Verify pin compatibility before substituting with different package options within the same logical family. Check for updated revisions from the manufacturer regarding pinout changes or enhanced features.
