ISPLSI-3160-125LQ

Overview

The ISPLSI-3160-125LQ is a high-density In-System Programmable Logic Device (ISPLD) belonging to the ispLSI 3000A family manufactured by Lattice Semiconductor Corporation. This component integrates up to 4,000 system gates within a single chip, providing substantial logic density for complex digital designs. It features non-volatile Flash technology that allows for unlimited in-system programming and reprogramming cycles without requiring removal from the circuit board. The device supports standard JTAG interfaces for testability and configuration, ensuring robust design verification and field updates.

Feature Summary

• Supports unlimited in-system programming via Flash memory technology
• Integrates up to 4,000 system gates for high-density logic applications
• Features full IEEE 1149.1 boundary scan compliance for testability
• Enables rapid prototyping and design iteration through reprogrammability

Applications

• Complex digital control systems requiring high gate counts
• Prototyping and development of custom logic circuits
• Industrial automation and instrumentation logic replacement
• Test fixtures and boundary scan implementation

Procurement Notes

Verify the specific suffix codes on the component marking against official Lattice documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with existing JTAG programming infrastructure. Confirm that the source document explicitly lists this part number as an active or supported product, as older ispLSI families may have transitioned to end-of-life status.

Selection Notes

Select this component when designs require higher logic density than lower-end ispLSI models but do not necessitate the complexity of FPGA architectures. Consider the 125 ns speed grade if timing constraints allow for slower propagation delays. Evaluate the need for non-volatile storage versus volatile FPGA solutions based on power consumption and boot-up time requirements.

Part Context

This device is part of the ispLSI 3000A series, which represents a generation of high-performance PLDs designed to bridge the gap between simple GALs and complex FPGAs. The series is known for its ease of use, predictable timing, and ability to replace multiple discrete logic components in a single package, simplifying PCB layout and reducing bill of materials.

Replacement Considerations

Direct replacements include other members of the ispLSI 3000A family with equivalent or higher gate counts, such as the ISPLSI-3256 or ISPLSI-3384, provided pin compatibility is verified. Cross-family migration to ispMACH 4000V/Z may be considered for similar functionality with different I/O characteristics.
