ISPLSI-3160-70LB272

Overview

The ISPLSI-3160-70LB272 is a Complex Programmable Logic Device (CPLD) from the Lattice ispLSI 3000 family. It features 20 macrocells and utilizes In-System Programmability with a minimum of 10,000 program/erase cycles. The device operates in a 272-pin Ball Grid Array (BGA) package and supports a maximum propagation delay of 15 nanoseconds.

Feature Summary

• Supports In-System Programmability for flexible design updates without removing the component from the circuit board.
• Features high-density logic architecture suitable for complex digital control applications.

Applications

• Digital signal processing systems
• Interface bridging between different protocol standards
• Complex state machine implementations

Procurement Notes

Verify the specific suffix LB272 to confirm the 272-pin BGA package configuration. Ensure the speed grade matches the 70ns designation for timing requirements. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Check for active production status to ensure long-term availability.

Selection Notes

Select this component when a moderate logic density with guaranteed In-System Programmability is required. The 272-pin BGA package offers high pin count for complex interconnects. Consider the 15ns delay specification against system clock speeds. Evaluate power consumption characteristics relative to other CPLD families for thermal management.
