LC4032V-10T44I

Overview

The LC4032V-10T44I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 32 macrocells and supports up to 30 I/O lines within a 44-pin Thin Quad Flat Package (TQFP). The device operates with a maximum clock frequency of 156 MHz and includes system-in-programmability capabilities. It utilizes a non-volatile configuration memory, allowing for instant-on functionality without external configuration devices.

Feature Summary

• 32 Macrocells with high-density logic architecture
• Supports up to 156 MHz system clock frequency
• System-in-programmable via JTAG interface
• Non-volatile configuration memory for instant-on operation

Applications

• General-purpose digital logic replacement
• Address/data bus decoding
• Interface bridging between different voltage domains
• Control logic for embedded systems

Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity upon receipt. Check moisture sensitivity level (MSL 3) requirements for storage and handling. Ensure ESD protection measures are in place during assembly. Validate pin compatibility with existing PCB footprints before procurement.

Selection Notes

Select this model when 32 macrocells are sufficient for the design complexity. The TQFP-44 package offers a balance of I/O count and board space. Consider the -10 speed grade if timing constraints require propagation delays consistent with the 10 ns variant. Verify voltage supply requirements match the target application's power rails.

Part Context

This component belongs to the ispMACH 4000V family, designed for low-power, high-performance CPLD applications. It serves as a successor to earlier ispMACH series, offering improved performance and lower power consumption while maintaining pin-to-pin compatibility with select legacy parts.

Replacement Considerations

Direct pin-compatible replacements may include other members of the ispMACH 4000V family with similar macrocell counts. Verify electrical characteristics and package dimensions before substitution. Cross-reference with Lattice's official obsolescence notices for alternative recommendations.
