LC4032ZE-5TN48C

Overview

The LC4032ZE-5TN48C 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 TQFP, it offers a typical standby current of 11.3 µA and supports JTAG In-System Programming.

Feature Summary

• Integrates 32 macrocells with SuperFAST performance up to 400 MHz
• Features 1.8V core voltage for low dynamic power and 5V tolerant I/Os
• Supports JTAG In-System Programming (ISP)
• Available in 48-pin TQFP package suitable for surface mount applications

Applications

• General-purpose logic replacement
• Bus bridging and protocol conversion
• Address decoding and control logic
• Interface adaptation between different voltage domains

Procurement Notes

Verify the specific suffix 'ZE' against official Lattice documentation to confirm automotive qualification status and temperature range extensions compared to standard commercial variants. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification. Confirm pinout compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when 32 macrocells are sufficient for the design logic requirements. The 5ns speed grade provides adequate timing margins for most synchronous designs operating below 400 MHz. Consider the 48-pin TQFP package constraints regarding available routing space and thermal dissipation capabilities within the target enclosure.

Part Context

This part belongs to the ispMACH 4000ZE family, which blends ispLSI 2000 and ispMACH 4A architectures. The ZE series typically denotes extended temperature or automotive-grade variants within the broader ispMACH 4000 product line, offering high density and predictable timing through global and output routing pools.

Replacement Considerations

Direct replacements include other members of the ispMACH 4000ZE family such as LC4032ZE-5T100C for increased I/O count in larger packages. Cross-family migration to ispMACH 4000V or Z series requires verification of pinout retention and voltage level compatibility.
