LC4032ZC-5TN48C

Overview

The LC4032ZC-5TN48C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000Z family. It features 32 macrocells, 36 logic array blocks, and 44 I/O pins in a 48-pin TQFP package. The device supports In-System Programmability via EEPROM technology and operates within a commercial temperature range of 0°C to 90°C. Key electrical parameters include a maximum operating frequency of 400 MHz, a propagation delay of 5 ns, and a supply voltage range of 1.8V to 3.6V.

Feature Summary

• ispMACH 4000Z architecture with 32 macrocells and 36 LABs
• In-System Programmability using non-volatile EEPROM memory
• High performance: 400 MHz max frequency and 5 ns propagation delay
• Supports 1.8V, 2.5V, and 3.3V supply voltages

Applications

• Address decoding and bus bridging
• State machine implementation
• Protocol conversion
• Glue logic replacement

Procurement Notes

Verify the specific suffix 'Z' against official Lattice documentation to confirm voltage compatibility and feature set differences compared to standard V or B series devices. Ensure the TN48 package type matches the target PCB footprint requirements. Confirm the '-5' speed grade corresponds to the required 5 ns timing constraints for the design.

Selection Notes

Select this component when designs require In-System Programmability without volatile configuration memory. The 32 macrocell count suits moderate complexity logic applications. Verify that the 44-pin TQFP package fits the available board space and that the 0°C to 90°C commercial temperature range meets environmental specifications.

Part Context

This part belongs to the ispMACH 4000Z family, which extends the high-performance capabilities of the 4000V/B/C families. The Z series typically offers enhanced power efficiency and support for lower voltage operations down to 1.8V, distinguishing it from earlier generations in the same macrocell count class.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other variants from the ispMACH 4000 family, such as the LC4032V or LC4032B series, provided their speed grades and voltage ranges meet the design requirements.
