ISPLSI2128VL-100LQ160

Overview

The ISPLSI2128VL-100LQ160 is a high-performance Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's ispLSI 2000 family. It features 256 macrocells and supports up to 32,768 usable gates. Operating at a maximum frequency of 100 MHz, it utilizes non-volatile Flash technology for instant-on functionality without external configuration memory. The device is housed in a 160-pin Low Profile Quad Flat Package (LQFP) with a 1.0 mm pitch, providing extensive I/O capabilities for complex digital logic applications requiring reliable, reprogrammable control.

Feature Summary

• 256 macrocells with 32,768 usable gates for complex logic implementation
• Non-volatile Flash architecture enabling instant-on operation without boot ROM
• Maximum operating frequency of 100 MHz for high-speed data processing
• 160-pin LQFP package with 144 user-accessible I/O pins

Applications

• High-density interface bridging between processors and peripheral devices
• Complex state machine implementations in industrial control systems
• Address decoding and bus arbitration in embedded computing architectures
• Protocol conversion logic for legacy system integration

Procurement Notes

Verify the specific suffix 'VL-100LQ160' matches the required speed grade (-100 ns) and package type (160-pin LQFP). Confirm RoHS compliance status if environmental regulations apply. Ensure the source provides genuine Lattice Semiconductor products to avoid counterfeit components affecting reliability.

Selection Notes

Select this component when non-volatile storage is critical to eliminate external configuration chips. The 100 MHz speed grade suits applications requiring moderate-to-high throughput. Evaluate pin count requirements against the 144 available I/Os. Consider thermal dissipation characteristics inherent to the 160-pin LQFP package under continuous load conditions.

Part Context

This part belongs to the ispLSI 2000 family, designed for mid-range CPLD applications. It serves as a successor to earlier E²CMOS technologies, offering higher density and lower power consumption. The series is widely used in telecommunications and networking equipment where reprogrammability and compact form factors are essential design constraints.

Replacement Considerations

Direct replacements include other Lattice ispLSI 2128 variants with compatible packages or speed grades. Cross-family migration to Lattice ispMACH 4000 may require schematic redesign due to architectural differences. Verify pin compatibility before substituting with generic CPLDs.
