ISPLSI2032-135LJ

Overview

The ISPLSI2032-135LJ is a high-density, in-system programmable complex programmable logic device (CPLD) from the Lattice ispLSI 2000E family. It features 32 I/O pins and 8 macrocells within a 44-pin PLCC package. The device utilizes advanced E2CMOS technology to provide non-volatile configuration with up to 100 erase/write cycles. Key electrical parameters include a maximum propagation delay of 7.5 ns and a maximum operating frequency of 133 MHz. It operates on a single 5V supply voltage ranging from 4.75V to 5.25V.

Feature Summary

• In-system programmability via IEEE 1149.1 compliant TAP interface
• Non-volatile E2CMOS technology supporting 100 erase/write cycles
• High-speed performance with 7.5 ns max propagation delay
• 32 I/O pins with 8 dedicated macrocells

Applications

• Address decoding and bus bridging
• State machine implementation
• Memory address translation
• Interface protocol conversion

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'LJ' corresponds to the 44-pin PLCC package variant. Check for end-of-life status as older CPLD families may have limited availability. Ensure design files are compatible with current Lattice development tools.

Selection Notes

Select this model for applications requiring moderate logic density with guaranteed non-volatility. Compare against the ispLSI 2032A series for potential timing improvements if higher speed is required. Consider pin count requirements carefully as the 32 I/O limit is fixed. Evaluate power consumption needs as static current varies by package type.

Part Context

This component belongs to the ispLSI 2000E family, representing an evolution of Lattice's early ISP CPLD architecture. It succeeded earlier GAL-based devices by offering reprogrammability without UV erasure. The family established standards for in-system programming that influenced subsequent FPGA and CPLD designs.

Replacement Considerations

The ISPLSI2032A-135LJ offers form and function compatibility with identical timing specifications. Verify package dimensions match exactly when substituting. No direct cross-brand equivalents exist due to proprietary E2CMOS architecture.
