LC4032C-5T44C

Overview

The LC4032C-5T44C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V/B/C/Z family. It features 32 macrocells, 36 logic blocks, and 30 user I/O pins within a 44-pin TQFP package. The device utilizes EEPROM technology for non-volatile configuration and supports In-System Programmability (ISP). Operating at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns, it functions within a commercial temperature range of 0°C to 90°C. Power specifications include a minimum supply voltage of 3V and a maximum of 3.6V.

Feature Summary

• ispMACH 4000 architecture with 32 macrocells and 36 logic blocks
• EEPROM-based non-volatile memory supporting In-System Programmability (ISP)
• Maximum operating frequency (fMAX) of 400 MHz
• Commercial temperature range support (0°C to 90°C)

Applications

• High-performance control applications
• Digital design boot loader execution
• Configuration data loading for Field Programmable Gate Arrays (FPGAs)
• Small-scale address decoding designs

Procurement Notes

Verify the specific suffix 'C' against official Lattice documentation to confirm the 1.8V core voltage variant. Ensure the 44-pin TQFP package matches the required footprint. Confirm that the commercial temperature grade (0°C to 90°C) meets the operational environment requirements before procurement.

Selection Notes

Select this component when a low-power CPLD solution with high-density logic resources is required. The 32-macrocell capacity suits moderate complexity designs. Verify that the 1.8V core voltage and 5V-tolerant I/O capabilities align with the system's power and interface standards.

Part Context

This part belongs to the ispMACH 4000V/B/C/Z family, which blends ispLSI 2000 and ispMACH 4A architectures. The 'C' designation typically indicates the 1.8V core voltage variant within this series, offering low dynamic power consumption while maintaining SuperFAST performance.

Replacement Considerations

Compatible substitutes within the same family include the LC4032V-5T44C (3.3V core) and LC4032B-5T44C (2.5V core), provided the system voltage levels are compatible. Other pin-compatible options in the 4032 series should be evaluated based on their specific voltage and temperature ratings.
