ISPLSI81080V-60LB272

Overview

The ISPLSI81080V-60LB272 is a high-performance Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's ispLSI 8000 family. It features 8,100 usable system gates and supports up to 240 macrocells for complex logic implementation. The device operates with a maximum propagation delay of 6.0 ns and utilizes a 5-volt supply voltage. It is housed in a 272-pin Low Profile Ball Grid Array (LPBGA) package, providing extensive I/O capabilities suitable for high-density digital control applications requiring reliable non-volatile configuration.

Feature Summary

• High density architecture with 8,100 usable system gates and 240 macrocells
• Fast switching speed with a maximum propagation delay of 6.0 ns
• Non-volatile configuration using E²CMOS technology for instant-on operation
• Supports 5-volt I/O interfaces compatible with legacy systems

Applications

• High-speed digital signal processing controllers
• Complex interface bridging between disparate bus protocols
• Industrial automation logic control units
• Telecommunications equipment protocol conversion

Part Context

This component belongs to the ispLSI 8000 series, representing Lattice's advanced CPLD technology utilizing E²CMOS process nodes. Unlike volatile FPGAs, this family integrates non-volatile memory directly on the die, eliminating the need for external configuration PROMs. The 81080 variant serves as a mid-to-high density solution within this lineage, balancing gate count with pin availability for robust system integration.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to specific package and timing constraints. Engineers should evaluate newer Lattice MachXO or CrossLink families for modern low-power alternatives, though these require design adaptation. Legacy support for the ispLSI 8000 series should be verified with the manufacturer regarding long-term availability and lifecycle status.
