LC4032ZC-75TN48I

Overview

The LC4032ZC-75TN48I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000Z family. It features 32 macrocells and supports up to 32 I/O pins in a TQFP-48 package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns. It utilizes EEPROM technology for non-volatile configuration, allowing for in-system programmability. The component is designed for industrial temperature ranges, supporting reliable operation in demanding electronic environments.

Feature Summary

• ispMACH 4000Z architecture with 32 macrocells
• EEPROM-based non-volatile memory for instant-on functionality
• Supports in-system programmability via JTAG or dedicated programming pins
• TQFP-48 surface-mount package suitable for space-constrained designs

Applications

• Address decoding and bus bridging in embedded systems
• State machine implementation for control logic
• Interface translation between different voltage domains
• General-purpose digital logic replacement

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature range variant when sourcing. Confirm the package type matches the required PCB footprint. Ensure the design tool suite supports the ispMACH 4000Z family for successful compilation and programming. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this model when non-vatile storage is required to eliminate external configuration memory. Compare against the V-series variants if lower cost is prioritized over specific Z-family features. Ensure the 32 macrocell density meets the logic requirements without excessive waste. Verify that the 7.5 ns delay specification satisfies the timing constraints of the target application.

Part Context

This part belongs to the ispMACH 4000Z family, which integrates high-performance CPLD logic with on-chip EEPROM. It serves as a successor to earlier volatile CPLD families, offering improved power efficiency and simplified system design by removing the need for external configuration devices. The 48-pin TQFP package provides a balance of I/O count and physical size.

Replacement Considerations

Direct pin-to-pin replacements may include other members of the ispMACH 4000Z family with similar I/O counts, such as the LC4032V-75TN48I, provided the temperature grade and specific electrical characteristics are compatible. Always verify logic capacity and timing parameters before substitution.
