ISPLSI2128VL-150LT176

Overview

The ISPLSI2128VL-150LT176 is a high-density Complex Programmable Logic Device (CPLD) from the ispLSI 2000VE family. It features 128 macrocells, 32 Logic Array Blocks (LABs), and 28 I/O pins housed in a 176-pin TQFP package. The device supports system-level in-system programmability via EEPROM technology and operates at maximum frequencies up to 150 MHz with a propagation delay of 4 ns.

Feature Summary

• Supports in-system programming for flexible design updates without removal from the circuit board
• Provides high-density logic resources through an architecture of 128 macrocells and 32 LABs
• Features superfast performance characteristics suitable for high-speed digital control applications

Applications

• High-speed interface bridging between disparate system components
• Complex glue logic replacement in industrial control systems
• Address decoding and bus arbitration in embedded computing architectures

Procurement Notes

Verify the specific suffix LT176 confirms the 176-pin Thin Quad Flat Package variant. Confirm the VL speed grade corresponds to the required 150 MHz operational frequency for your target application timing constraints. Ensure the manufacturer source is Lattice Semiconductor or an authorized distributor to guarantee component authenticity and traceability.

Selection Notes

Select this component when designs require moderate logic density with guaranteed high-speed performance. The 128-macrocell capacity offers a balance between resource utilization and pin count. Consider the TQFP-176 package if surface-mount assembly with accessible peripheral pins is preferred over ball grid array options.

Part Context

This part belongs to the ispLSI 2000VE series, representing a generation of CMOS EEPROM-based CPLDs designed for high-performance applications. These devices utilize Lattice's proprietary SuperFast architecture to deliver low power consumption while maintaining fast signal propagation delays across complex logic functions.

Replacement Considerations

Direct replacements within the same family include the ISPLSI2128V-150LT176. Verify that any substitute maintains identical pinout compatibility and electrical specifications to ensure seamless integration into existing hardware layouts.
