LC4032ZC-5TN48I

Overview

The LC4032ZC-5TN48I is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000Z family, manufactured by Lattice Semiconductor. It features 32 macrocells and 36 logic array blocks within a 48-pin Thin Quad Flat Package (TQFP). The device supports In-System Programmability (ISP) via EEPROM technology and operates with a supply voltage range of 1.8V to 3.6V. It provides 46 user I/O pins and has a maximum propagation delay of 5ns. The component is rated for industrial temperature applications, functioning reliably between -40°C and +105°C.

Feature Summary

• ispMACH 4000Z architecture with 32 macrocells and 36 LABs
• In-System Programmability (ISP) using non-volatile EEPROM memory
• Industrial temperature range operation (-40°C to +105°C)
• Supports 1.8V, 2.5V, and 3.3V supply voltages

Applications

• High-speed interface bridging in industrial automation systems
• Address decoding and control logic in embedded controllers
• State machine implementation for communication protocols
• Replacement for legacy GAL devices in existing hardware designs

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +105°C) against the manufacturer's datasheet. Confirm package type is TQFP-48. Check current production status as older CPLD families may have end-of-life implications. Ensure programming tools support the ispMACH 4000Z series.

Selection Notes

Select this model when an industrial-grade CPLD with ISP capability is required. Compare the 32 macrocell capacity against design complexity requirements. Verify that the 48-pin TQFP footprint fits the PCB layout constraints. Consider power consumption differences between 1.8V and 3.3V operation modes based on system battery or supply limitations.

Part Context

This part belongs to the ispMACH 4000Z family, which offers high performance and density for complex logic applications. The 'Z' variant typically denotes enhanced speed and lower power characteristics compared to previous generations like the V or C series. It serves as a drop-in replacement for many GAL and PAL devices while offering significantly higher logic density and reprogrammability.

Replacement Considerations

Direct pin-compatible replacements within the same family include other LC4032Z variants with different speed grades (e.g., LC4032ZC-5TN48C for commercial temperature). Cross-family migration to newer Lattice platforms requires schematic and code verification.
