ISPLSI2032-135LT48

Overview

The ISPLSI2032-135LT48 is a Complex Programmable Logic Device (CPLD) from the ispLSI 2000A family, manufactured by Lattice Semiconductor. It features 32 macrocells and supports up to 32 I/O pins within a 48-pin TQFP package. The device operates at a maximum frequency of 167 MHz with a typical propagation delay of 10 ns. It utilizes EEPROM technology for non-volatile configuration and functions on a 5 V supply voltage. This component is designed for commercial temperature ranges between 0°C and +70°C.

Feature Summary

• 32 Macrocells with 8 Logic Array Blocks (LABs)
• EEPROM-based non-volatile memory
• 167 MHz maximum operating frequency
• 48-pin Thin Quad Flat Package (TQFP)

Applications

• General-purpose digital logic implementation
• Bus protocol conversion
• Address decoding and control logic

Procurement Notes

Verify current product status as the ispLSI 2000A series has been subject to discontinuation notices. Confirm availability through authorized distributors or secondary market suppliers. Ensure compliance with RoHS directives if required for specific manufacturing standards.

Selection Notes

Select this model when 32 macrocells are sufficient for the design complexity. The 10 ns delay meets requirements for moderate-speed synchronous logic. Consider the 5 V operating voltage compatibility with legacy systems. Evaluate pin count constraints against the 48-pin TQFP footprint.

Part Context

This part belongs to the ispLSI 2000A series, which succeeded earlier ispLSI 2000 devices. It offers improved performance over previous generations while maintaining backward compatibility with ispDesign EXpress software tools. The series was widely used in industrial and consumer electronics before being phased out.

Replacement Considerations

Direct replacements may be limited due to discontinuation. Review Lattice's ispMACH 4000V or ispMACH 5000Z families for modern alternatives. Verify pinout compatibility and logic density requirements when migrating to newer CPLD architectures.
