Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix against the manufacturer's current portfolio, as legacy CPLD families may have discontinued variants. Confirm that the 388-ball BGA package availability aligns with current production status. Ensure design tools support the ispLSI 5000VA series for programming and simulation. Check for any environmental compliance certifications required for the specific batch.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require high pin counts (up to 288) and dense logic resources within a single chip. The 388-pin BGA package is suitable for PCB-efficient layouts but requires appropriate footprint design. Consider the 7.5 ns delay for timing-critical paths and utilize the dedicated clock pins (CLK0-CLK3) for synchronous designs. Evaluate power consumption estimates based on the number of active product terms and switching frequency.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 5000VA family, which expands upon the previous ispLSI 5000V architecture with enhanced interconnect structures for optimal pin locking. The 5384VA variant represents the highest density option in this specific generation, offering 384 macrocells. It serves as a bridge between traditional GALs and modern FPGAs, providing non-volatile configuration without the complexity of SRAM-based devices.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to the proprietary SuperWIDE architecture. Cross-reference with other ispLSI 5000VA models like the 5256VA for lower density needs. Verify compatibility with existing programming hardware and software tools before substituting.
