LC4032V-10T48I

Overview

The LC4032V-10T48I is a complex programmable logic device (CPLD) belonging to the ispMACH 4000V family. It features 32 macrocells and supports up to 26 user I/Os within a 48-pin Thin Quad Flat Package (TQFP). The device operates with a maximum propagation delay of 10 ns and includes non-volatile configuration memory (NVCM) for instant-on functionality. Electrical specifications include a supply voltage range of 2.7 V to 3.6 V, with static current consumption as low as 5 mA. The architecture utilizes high-speed CMOS technology to deliver reliable performance in embedded control applications.

Feature Summary

• Non-volatile Configuration Memory (NVCM) enables instant-on operation without external configuration devices.
• High-density architecture providing 32 macrocells and up to 26 flexible I/O pins.
• Fast switching speed with a maximum propagation delay of 10 ns.
• Supports multiple package options including TQFP, suitable for space-constrained designs.

Applications

• Embedded system controller replacement
• Address/data bus multiplexing
• Protocol conversion interfaces

Procurement Notes

Verify the specific suffix 'T48I' confirms the 48-pin TQFP package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to ordering. Ensure the part number matches the exact revision required for your design compatibility.

Selection Notes

Select this component when non-volatile storage is required to eliminate external configuration flash memory. Compare macrocell count against project logic requirements; the LC4032V offers 32 macrocells. Verify pin count sufficiency for interface needs. Consider the 10 ns speed grade if timing constraints are tight. Evaluate package availability in TQFP format for PCB layout compatibility.

Part Context

This device is part of the Lattice ispMACH 4000V family, designed for cost-sensitive, high-volume applications requiring small form factors. It succeeds earlier ispMACH 4000 variants with improved power efficiency and density. The family is widely used in consumer electronics and industrial automation where low power and instant-on capabilities are critical.

Replacement Considerations

Direct replacements within the same family include LC4032V-10TN48I (same package, different temperature grade if applicable) or LC4032ZE-10T48I (Enhanced version). Cross-family migration to ispMACH AXP may require schematic redesign due to architectural differences.
