ISPLSI5384VA-70LB388I

Overview

The ISPLSI5384VA-70LB388I is a Complex Programmable Logic Device (CPLD) from the ispLSI 5000VA series manufactured by Lattice Semiconductor. It features 384 macrocells and supports up to 296 I/O pins within a 388-pin BGA package. The device operates on a single 3.3V supply voltage with a typical propagation delay of 7.5 ns. It utilizes non-volatile EEPROM technology for configuration storage, allowing for instant-on functionality without external memory. The component is designed for high-density logic applications requiring robust performance in industrial and commercial environments.

Feature Summary

• High-density architecture with 384 macrocells and 18,000 usable gates
• Supports up to 296 user I/O pins for complex system integration
• Non-volatile EEPROM configuration ensures instant power-up operation
• Single 3.3V supply voltage operation with low power consumption

Applications

• High-speed digital signal processing interfaces
• Protocol conversion and bridging in telecommunications equipment
• Complex glue logic replacement in industrial control systems
• Address decoding and bus buffering in embedded computing platforms

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range (-40°C to +85°C). Confirm the 388-pin Ball Grid Array (BGA) footprint requirements during PCB design. Check current availability status as older CPLD families may have limited stock or end-of-life implications. Ensure programming tools support the ispLSI 5000VA series architecture.

Selection Notes

Select this model when designs require high pin counts and moderate speed with non-volatile configuration. Compare against the standard commercial grade variant if industrial temperature ratings are not required. Consider the 388-pin BGA package constraints for board space and thermal management. Verify that the 3.3V I/O levels match the target system interface voltages.

Part Context

This component belongs to the ispLSI 5000VA family, representing an evolution in Lattice's CPLD portfolio with enhanced performance and lower power compared to previous generations. It serves as a high-capacity solution for replacing discrete logic and smaller PLDs in dense electronic assemblies. The VA series emphasizes reliability and ease of use through its integrated non-volatile configuration technology.

Replacement Considerations

Direct pin-to-pin replacements within the same package and speed grade should be prioritized. Evaluate other members of the ispLSI 5384VA family for different speed grades or temperature ranges. Cross-reference with newer Lattice FPGA families if additional DSP or memory resources are needed, though architectural differences require redesign.
