ISPLSI81080V-90LB492

Overview

The ISPLSI81080V-90LB492 is a Complex Programmable Logic Device (CPLD) belonging to the ispLSI 8000V series. It features 1080 macrocells and operates at a maximum system clock frequency of 90 MHz, indicated by the -90 speed grade. The device utilizes a 492-ball Ball Grid Array (BGA) package for high-density interconnect capabilities. It supports in-system programming via the JTAG interface, allowing for field updates without removal from the circuit board. The component is designed for high-performance logic applications requiring non-volatile configuration storage.

Feature Summary

• Supports in-system programmability for flexible design iterations and field updates
• Utilizes Flash-based technology for non-volatile configuration retention
• Features high-density macrocell architecture for complex logic implementation

Applications

• High-speed digital signal processing interfaces
• System controller logic in embedded platforms
• Address decoding and bus bridging in industrial systems

Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance for this specific part number. Confirm package integrity and date codes upon receipt. Ensure ESD protection protocols are followed during handling due to the BGA form factor. Cross-reference the manufacturer's official documentation for any recent lifecycle changes or obsolescence notices before finalizing procurement orders.

Selection Notes

Select this component when a high pin count and significant logic capacity are required in a single package. The 492-ball BGA footprint necessitates careful PCB layout considerations for thermal management and signal integrity. Compare against lower density variants if power consumption or board space is constrained, ensuring the 90 MHz performance meets the target system timing requirements.

Part Context

This device is part of Lattice Semiconductor's ispLSI 8000V family, which represents high-density CPLDs. The family is known for combining Flash memory technology with high-performance logic blocks. This specific model serves as a drop-in replacement for older GAL and PAL devices in legacy designs while offering greater flexibility and reprogrammability.

Replacement Considerations

Compatible substitutes include the ISPLSI81080V-125LB492 for slower speed grades and the ISPLSI81080V-60LB272 for different package options. Verify pin compatibility and I/O voltage levels when substituting. Check for updated packaging suffixes that may affect mechanical dimensions or lead finish specifications.
