LC4032ZC-75T48E

Overview

The LC4032ZC-75T48E is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000Z family manufactured by Lattice Semiconductor. It features 32 macrocells and supports up to 32 user I/O pins within a TQFP-48 surface-mount package. The device operates on a 3.3V supply voltage with a maximum operating frequency of 400 MHz and a typical propagation delay of 7.5 ns. It utilizes non-volatile EEPROM technology for configuration storage, enabling in-system programmability without external memory components.

Feature Summary

• ispMACH 4000Z architecture with 32 macrocells and 36 logic blocks
• In-system programmability via JTAG or serial programming
• EEPROM-based non-volatile configuration storage
• Supports 3.3V, 2.5V, and 1.8V I/O standards

Applications

• Address decoding and bus bridging
• State machine implementation
• Logic replacement for discrete gate arrays
• Interface translation between different voltage domains

Procurement Notes

Verify the specific suffix 'E' against official Lattice documentation to confirm if it denotes an extended temperature range or specific environmental compliance status not covered by standard commercial variants. Ensure the TQFP-48 package availability matches current manufacturing schedules. Confirm RoHS compliance details directly with the manufacturer or authorized distributors prior to procurement.

Selection Notes

Select this component when a design requires moderate logic density with low power consumption and non-volatile configuration. Compare the 32 macrocell capacity against the LC4032V series to determine if the enhanced features of the Z family, such as improved performance or additional I/O flexibility, are necessary for the specific application requirements.

Part Context

This part belongs to the ispMACH 4000Z family, which represents an evolution of the popular ispMACH 4000V series. The Z family offers improvements in speed and power efficiency while maintaining compatibility with existing design tools and pinouts where applicable. It serves as a drop-in replacement for legacy GAL devices in many applications requiring higher complexity.

Replacement Considerations

Check for direct cross-references within the ispMACH 4000Z family, such as the LC4032ZC-75T48C for commercial temperature variants. Verify pinout compatibility if substituting with older V-series parts, noting potential differences in I/O drive strength or configuration options.
