ISPGDX80VA-3T100

Overview

The ISPGDX80VA-3T100 is a high-performance in-system programmable gate array from the ispDX family, featuring 80 macrocells and 256 user I/Os. It operates at supply voltages of 2.5V or 3.3V with a maximum system clock frequency of 240 MHz. The device utilizes Flash technology for non-volatile configuration retention, allowing unlimited reprogramming without external memory. It supports JTAG boundary scan testing and offers flexible global and local clocking resources to meet complex timing requirements.

Feature Summary

• Flash-based non-volatile configuration eliminates the need for external PROM devices
• Supports in-system programming via JTAG interface for rapid prototyping and field updates
• High-speed performance with dedicated global clock networks and flexible routing

Applications

• Complex logic replacement in industrial control systems
• Interface bridging between different voltage domains
• State machine implementation in communication equipment

Procurement Notes

Verify the specific suffix codes on the datasheet to confirm package type, temperature range, and lead-free status. Ensure the ordering part number matches the required speed grade and voltage specifications exactly. Cross-reference the manufacturer's official documentation for any recent revisions that may affect pin compatibility or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when non-volatile configuration and high I/O density are required in a compact TQFP package. Consider the 80 macrocell capacity against design complexity and verify that the 240 MHz maximum frequency meets timing constraints. Evaluate power consumption differences between 2.5V and 3.3V operation modes based on system power budget requirements.

Part Context

This device belongs to Lattice Semiconductor's ispDX family of Flash PLDs, designed for cost-sensitive applications requiring frequent reconfiguration. It bridges the gap between simple GALs and larger FPGA solutions, offering deterministic timing and easy integration into existing PCB layouts without additional configuration memory components.

Replacement Considerations

Direct replacements within the same family include ISPGDX80A variants with different speed grades or package options. Verify pin-to-pin compatibility and electrical specifications when substituting with other ispDX series parts. Consult the manufacturer's cross-reference guide for validated alternatives with similar macrocell counts and I/O configurations.
