ISPLSI8600V-90LB492

Overview

The ISPLSI8600V-90LB492 is a high-density Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's ispLSI 8000 family. It features 1,024 macrocells and supports up to 352 I/O pins within a 492-ball Ball Grid Array (BGA) package. The device utilizes E² CMOS technology to achieve maximum operating frequencies of 225 MHz with a propagation delay of 3.5 ns. It offers in-system programmability via JTAG and supports mixed-voltage I/O standards including 3.3V and 5V operation.

Feature Summary

• High-density architecture with 1,024 macrocells for complex logic implementation
• SuperFAST performance enabling high-speed data processing at 225 MHz
• In-system programmability allowing field updates without desoldering
• Mixed-voltage I/O support for interfacing with diverse system components

Applications

• High-speed interface bridging between disparate system buses
• Complex glue logic replacement in industrial control systems
• Address decoding and state machine implementation in telecommunications equipment
• Prototyping and final production designs requiring reprogrammability

Procurement Notes

Verify the specific suffix codes on the component marking against official Lattice documentation to confirm voltage grade, temperature range, and lead-free status. Ensure compatibility with your programming hardware, as ispLSI devices require specific JTAG adapters or universal programmers supporting the ispJTAG protocol. Confirm package integrity upon receipt, as BGA packages are sensitive to mechanical stress during handling and storage.

Selection Notes

Select this device when design requirements exceed the capacity of lower-density CPLDs but do not necessitate the complexity of an FPGA. The 1,024 macrocell count provides substantial logic resources while maintaining deterministic timing characteristics typical of PLDs. Consider the 492-ball BGA package constraints regarding PCB real estate and thermal management capabilities during the layout phase.

Part Context

This component belongs to the ispLSI 8000 family, representing Lattice's high-performance CPLD lineage. It combines the ease of use and fast system speed of PLDs with the density and flexibility of field-programmable gate arrays. The family is known for its SuperFAST global interconnect and wide input gating capabilities, making it suitable for demanding digital logic applications.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to the specific macrocell count and package configuration. Review Lattice's upward compatibility matrix; however, migration to newer families like MachXO3 or iCE40 UltraPlus typically requires schematic and bitstream redesign rather than simple substitution.
