LC4032B-5TN44I

Overview

The LC4032B-5TN44I is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000V/B/C/Z family, manufactured by Lattice Semiconductor. It features 32 macrocells and supports In-System Programmability via JTAG. The device operates with a supply voltage range of 3V to 3.6V and utilizes EEPROM technology for non-volatile configuration storage. Packaged in a 44-pin Thin Quad Flat Package (TQFP), it provides 30 user I/O pins. The component is designed for commercial temperature ranges and offers high-performance logic capabilities suitable for various digital control applications.

Feature Summary

• 32 Macrocells with 36 Logic Blocks
• In-System Programmability (ISP) via JTAG
• EEPROM Non-Volatile Memory Technology
• 44-Pin TQFP Surface Mount Package

Applications

• Digital logic replacement
• Bus bridging and protocol conversion
• Address decoding and control logic

Procurement Notes

Verify the specific suffix 'B' indicates the 2.5V core voltage variant within the ispMACH 4000 family. Confirm package dimensions match the 10x10mm footprint specification for the 44-TQFP. Ensure design tools support the ispMACH 4000 architecture for programming and simulation.

Selection Notes

Select this model when 32 macrocells are sufficient for the design complexity. The 5ns propagation delay rating suits moderate-speed synchronous designs. Verify that the 3.3V I/O tolerance requirements align with the system interface voltages.

Part Context

This part is part of the ispMACH 4000 series, which blends ispLSI 2000 and ispMACH 4A architectures. The 'B' designation typically refers to the 2.5V core voltage version, distinct from the 3.3V (V) or 1.8V (C) variants in the same density class.

Replacement Considerations

Compatible replacements include other members of the ispMACH 4000 family such as LC4032V-5TN44I or LC4032Z-5TN44I, provided the core voltage and I/O standards are compatible.
