ISPLSI 5384VA-125LB272

Complex Programmable Logic Devices Overview

The ispLSI 5384VA-125LB272 is a high-density, in-system programmable complex programmable logic device (CPLD) from Lattice Semiconductor. It utilizes E2CMOS technology to provide non-volatile configuration with 18,000 PLD gates and 384 macrocells organized into twelve Generic Logic Blocks (GLBs). The device operates on a single 3.3V supply while supporting user-selectable 3.3V or 2.5V I/O levels. Key electrical specifications include a maximum operating frequency of 125 MHz and a typical propagation delay of 7.5 ns. It features a SuperWIDE architecture with 32-input GLBs and supports up to 288 I/O pins via Ball Grid Array packages.

Complex Programmable Logic Devices Feature Summary

• SuperWIDE Architecture: Features 384 macrocells distributed across twelve 32-register GLBs with a Global Routing Pool for efficient interconnects.
• High Performance: Achieves fmax of 125 MHz with a propagation delay of 7.5 ns using E2CMOS technology.
• Flexible I/O: Supports user-selectable 3.3V or 2.5V output levels with independent VCCIO control, compatible with 5V TTL devices.
• In-System Programmability: Allows reprogramming via IEEE 1149.1 JTAG interface without removing the device from the PCB.

Complex Programmable Logic Devices Applications

• Complex state machine implementations requiring fast counters and address decoders.
• Bus bridging and protocol conversion between different voltage domains.
• Address decoding and memory interface logic in embedded systems.
• General-purpose digital logic replacement for legacy discrete logic circuits.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm package integrity and pin compatibility before integration. Check for specific product change notifications regarding manufacturing updates. Ensure design tools support the legacy ispLSI 5000VA family for programming and simulation.

Complex Programmable Logic Devices Selection Notes

Select this model when 384 macrocells and high-speed performance are required. The -125 speed grade is suitable for applications needing 125 MHz operation. The LB272 suffix indicates a 272-ball BGA package. Consider the -I variant if industrial temperature range (-40°C to +85°C) is necessary compared to the commercial grade. Verify I/O voltage requirements to utilize the flexible VCCIO feature effectively.

Complex Programmable Logic Devices Part Context

This device belongs to the ispLSI 5000VA family, which succeeded the ispLSI 5000 series. It shares architectural similarities with the ispLSI 2000 and ispMACH 4A families but offers higher density. The family is characterized by its non-volatile EEPROM technology and in-system programmability, targeting high-volume consumer and industrial electronics where reconfigurability reduces time-to-market.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same package and pinout are limited due to the discontinued status of the ispLSI 5000VA line. Functional equivalents may require redesigning the board layout. Consider migrating to modern Lattice MachXO or CrossLink-N families for new designs, though pinouts will differ significantly.
