ISPLSI3192-70LB272

Overview

The ISPLSI3192-70LB272 is a Complex Programmable Logic Device (CPLD) from the ispLSI 5000V family, manufactured by Lattice Semiconductor. It features 192 I/O pins and utilizes a 272-ball Ball Grid Array (BGA) package with dimensions of 27x27 mm. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports system-in-programmability for in-system configuration. Key electrical parameters include a maximum propagation delay of 7.5 ns and a logic capacity of 384 macrocells.

Feature Summary

• High-density architecture with 384 macrocells and 18,000 usable gates
• System-in-Package capability allowing reprogramming after soldering
• 272-ball BGA package (27x27 mm) optimized for high pin count applications
• CMOS technology supporting 3.0 V to 3.6 V power supply

Applications

• High-speed interface bridging in telecommunications equipment
• Complex glue logic replacement in industrial control systems
• Address decoding and bus buffering in embedded computing platforms

Procurement Notes

This component is identified as a discontinued product within the Lattice portfolio. Verification of availability requires checking authorized distributors for remaining stock or obsolete inventory. Designers should confirm the final status through official Lattice channels before initiating procurement processes.

Selection Notes

Select this model when a CPLD solution with over 300 macrocells and extensive I/O connectivity is required. The 70 speed grade indicates suitability for moderate-to-high frequency digital logic operations. Ensure the design accommodates the specific 272-ball BGA footprint and thermal requirements associated with this package type.

Part Context

The ISPLSI3192-70LB272 belongs to the ispLSI 5000V series, representing an evolution of Lattice's CMOS CPLD technology. This series introduced System-in-Package functionality, distinguishing it from earlier non-volatile PLDs that required off-board programming. It serves as a bridge between low-density PLDs and higher-end FPGAs.

Replacement Considerations

As a discontinued part, direct replacements are limited. Review Lattice's MachXO or CrossLink families for modern FPGA alternatives with comparable I/O counts. Verify pin compatibility and logic density against current available devices to ensure functional equivalence.
