ISPLSI2032-135LJI

Overview

The ISPLSI2032-135LJI is a high-density complex programmable logic device (CPLD) from the ispLSI 2000E series, manufactured by Lattice Semiconductor. It features 32 macrocells and 32 universal I/O pins within a 44-pin plastic leaded chip carrier (PLCC) package. The device operates with a maximum propagation delay of 13.5 ns and supports a supply voltage range of 4.75V to 5.25V. Key architectural elements include two dedicated input pins, three dedicated clock inputs, and one global output enable pin. It utilizes in-system programmability via the JTAG interface for flexible design implementation.

Feature Summary

• Supports in-system programmability through the JTAG interface for efficient design updates
• Features high-density architecture with 32 macrocells and universal I/O capabilities
• Includes dedicated global control signals such as dedicated clock and output enable inputs

Applications

• General-purpose digital logic replacement
• Address decoding and bus protocol conversion
• State machine implementation in embedded systems

Procurement Notes

Verify the specific suffix 'LJI' corresponds to the 44-pin PLCC package and commercial temperature grade. Confirm that the component is sourced from authorized distributors to ensure authenticity, as this part may be subject to obsolescence or lifecycle changes. Check for RoHS compliance status if required for modern manufacturing standards.

Selection Notes

Select this device when a moderate density CPLD with fast propagation delays is required for replacing discrete logic gates. The 13.5 ns speed grade offers a balance between performance and power consumption. Consider the 44-pin PLCC form factor for legacy socket compatibility or specific board layout constraints requiring through-hole mounting options.

Part Context

This component belongs to the ispLSI 2000E family, which provides non-volatile configuration memory allowing the device to retain its program without external storage. The family is designed for applications requiring rapid prototyping and final system integration with low power consumption characteristics typical of Lattice's CPLD portfolio.

Replacement Considerations

Direct substitutes include the ISPLSI2032-135LJ (same electrical specs, different package variant) or the ISPLSI2032A-135LJI (enhanced version). Cross-reference with other ispLSI 2000E devices like the 2032A series for functional equivalence.
