ISPLSI3256E-70LQA

Overview

The ISPLSI3256E-70LQA is a Complex Programmable Logic Device (CPLD) belonging to the Lattice ispLSI 3000 family. It features a 15 ns maximum propagation delay time and operates within a commercial temperature range of 0°C to 70°C. The component utilizes a 304-ball Ball Grid Array package with an exposed pad, specifically identified as a 304-BFQFP configuration. This device provides high-density logic capabilities suitable for complex digital design implementations.

Feature Summary

• Supports high-speed logic operations with a maximum propagation delay of 15 nanoseconds
• Designed for commercial applications operating between 0°C and 70°C ambient temperatures
• Utilizes a 304-ball BGA package structure for compact system integration

Applications

• Complex digital logic implementation in embedded systems
• System replacement for legacy designs using the ispLSI 3256E series footprint
• High-density programmable logic solutions requiring fast switching speeds

Procurement Notes

Verify that the specific suffix 'LQA' corresponds to the 304-ball BFQFP package variant rather than other pin counts like LB320 or LQA variants with different thermal profiles. Confirm the manufacturer is Lattice Semiconductor Corporation and check for RoHS compliance status if required by your assembly process. Ensure the part number matches the exact electrical specifications for the 70 speed grade.

Selection Notes

Select this component when a 15 ns delay specification is mandatory for timing-critical paths within a commercial temperature environment. The 304-ball package requires appropriate PCB layout considerations for ball grid array soldering. Consider this part if existing designs utilize the ispLSI 3256E architecture and require a direct functional equivalent with verified compatibility.

Part Context

This CPLD belongs to the widely adopted ispLSI 3000 family, known for its non-volatile SRAM-based technology. The family offers flexibility for prototyping and production runs. The ISPLSI3256E variant represents a specific density level within this lineage, providing a balance of logic resources and I/O count for mid-range complexity applications.

Replacement Considerations

The ISPLSI3256E-70LQA is fully compatible with systems designed around the ispLSI 3256E series footprint and electrical parameters. It fits seamlessly into existing designs without modification.
