ISPLSI 2032E-180LJ44

Complex Programmable Logic Devices Overview

The ispLSI 2032E-180LT44 is a high-density, in-system programmable complex programmable logic device (CPLD) manufactured by Lattice Semiconductor. It features 1000 PLD gates, 32 universal I/O pins, and 32 registers within a single Megablock architecture. The device utilizes E2CMOS technology to achieve a maximum operating frequency of 180 MHz with a propagation delay of 5.0 ns. It supports non-volatile reprogrammability via IEEE 1149.1 JTAG and offers user-selectable 3.3V or 5V I/O levels in the 48-pin TQFP package.

Complex Programmable Logic Devices Feature Summary

• High Density Logic: Contains 1000 PLD gates, 32 I/O pins, and 32 registers organized into eight Generic Logic Blocks (GLBs).
• E2CMOS Technology: Provides non-volatile reprogrammability with 10,000 erase/reprogram cycles and low power consumption through unused product term shutdown.
• In-System Programmability: Supports ISP via the IEEE 1149.1 JTAG Test Access Port for rapid prototyping and field updates.
• Flexible I/O Configuration: The 48-pin package allows user-selectable 3.3V or 5V I/O supply voltages and PCI-compatible outputs.

Complex Programmable Logic Devices Applications

• Glue logic replacement in digital systems combining structured designs and random logic.
• Address decoding and state machine implementation utilizing wide input gating capabilities.
• Prototyping and field-upgradeable logic circuits requiring non-volatile reconfiguration.
• Systems requiring mixed voltage interfaces with 3.3V and 5V compatibility.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix '180' corresponds to the required 180 MHz performance specification. Confirm the package type 'T44' matches the design footprint requirements. Ensure the ordering suffix aligns with the commercial temperature range indicated by the blank grade designation. Cross-reference the datasheet revision date against current manufacturing notices.

Complex Programmable Logic Devices Selection Notes

Select this component when a high-density CPLD with 1000+ gates and non-volatile reprogrammability is required. The -180 speed grade provides a balance between performance and power consumption compared to faster variants. Consider the 48-pin TQFP package if mixed 3.3V/5V I/O operation is necessary, as the 44-pin variant lacks this feature. Evaluate the 3.5 ns typical propagation delay against system timing constraints.

Complex Programmable Logic Devices Part Context

The ispLSI 2032E series represents an evolution of the earlier ispLSI 2032 family, offering upward compatibility while introducing enhanced features like user-selectable I/O voltages in specific packages. The -180 variant sits within the commercial speed grades, positioned below the -200 and -225 options. This device belongs to the SuperFAST High Density PLD line, designed for applications needing the flexibility of FPGAs with the ease of use of traditional PLDs.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2032E-180LJ44 serves as a functional equivalent for the 44-pin PLCC package variant. For direct pin-to-pin replacement in existing 44-pin footprints, verify the -180LJ44 part number. Note that the 48-pin TQFP version offers additional I/O voltage flexibility not present in the 44-pin configuration.
