LC4032C-75T48C

Overview

The LC4032C-75T48C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000C family. It features 32 macrocells and operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns. The device utilizes EEPROM technology for non-volatile configuration, supporting in-system programmability. It functions within a supply voltage range of 3.0 V to 3.6 V and is housed in a 48-pin TQFP package. The component supports independent output enable control and includes 36 logic blocks for high-density design implementation.

Feature Summary

• ispMACH 4000C architecture with 32 macrocells and 36 logic blocks
• EEPROM-based non-volatile memory enabling in-system reprogrammability
• Maximum operating frequency of 400 MHz with 7.5 ns propagation delay
• Independent output enable control per I/O pin

Applications

• High-speed interface bridging
• Address decoding and state machine implementation
• System controller logic replacement

Procurement Notes

Verify the specific suffix 'C' against the manufacturer's current datasheet to confirm pinout compatibility and electrical characteristics relative to other variants in the LC4032 series. Ensure the TQFP-48 package availability aligns with project requirements. Confirm RoHS compliance status through official documentation prior to procurement.

Selection Notes

Select this component when a non-volatile CPLD solution is required to replace complex discrete logic or gate arrays. The 32 macrocell count is suitable for moderate complexity designs requiring deterministic timing. Consider the 7.5 ns speed grade if system timing margins allow; faster grades are available in the same family if higher performance is necessary.

Part Context

This part belongs to the Lattice ispMACH 4000C family, which succeeded the earlier ispMACH 4000A series. The family is characterized by its use of EEPROM technology, allowing for unlimited reprogramming cycles without the need for UV erasure. This generation offers improved performance and density compared to previous iterations while maintaining low power consumption profiles.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other speed grades from the LC4032V or LC4032Z families, provided the timing specifications meet the design requirements. Verify that the target replacement maintains the same EEPROM configuration method and voltage levels.
