LC4032ZE-4TN48C

Overview

The LC4032ZE-4TN48C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000ZE family, manufactured by Lattice Semiconductor. It features 32 macrocells and operates with a maximum frequency of 400 MHz. The device utilizes a 1.8V core voltage for low dynamic power consumption while supporting 5V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces. Packaged in a 48-pin Thin Quad Flat Package (TQFP), it supports JTAG In-System Programming. The component is designed for applications requiring high performance and density migration within a compact form factor.

Feature Summary

• Integrates 32 macrocells with SuperFAST performance up to 400 MHz
• Supports 5V tolerant I/Os for LVCMOS 3.3, LVTTL, and PCI interfaces
• Features 1.8V core voltage for low dynamic power consumption
• Includes Global Routing Pool and Output Routing Pool for timing predictability

Applications

• High-density logic replacement in industrial control systems
• Interface bridging between 5V and 3.3V domains
• Address decoding and bus buffering in embedded systems

Procurement Notes

Verify the specific suffix 'ZE' against official Lattice documentation to confirm automotive temperature range qualification (-40°C to +130°C junction temperature). Ensure the TQFP-48 package matches the target PCB footprint. Confirm RoHS compliance status via the manufacturer's current datasheet revision.

Selection Notes

Select this model when 32 macrocells are sufficient for the design logic requirements. The 4ns speed grade offers a balance between performance and power. Consider the 48-pin TQFP package constraints regarding pin count versus available I/O needs. Verify that the 1.8V core supply is available in the target system architecture.

Part Context

This part belongs to the ispMACH 4000ZE family, which blends ispLSI 2000 and ispMACH 4A architectures. The family provides solutions for low-power, high-performance CPLD applications. The ZE variant specifically targets automotive and industrial environments requiring extended temperature ranges compared to standard commercial grades.

Replacement Considerations

Direct pin-to-pin replacements within the same family include LC4032Z-4TN48C (commercial grade) or LC4032V-4TN48C (different speed/package characteristics). Verify temperature ratings and electrical specifications before substituting.
