LC4032ZC-75T48C

Overview

The LC4032ZC-75T48C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000ZE family. It features 32 macrocells and supports up to 32 user I/Os within a 48-pin TQFP package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns. It utilizes non-volatile EEPROM technology for configuration storage, allowing for in-system programmability and multiple reprogramming cycles. The component is designed for surface-mount installation and functions within a standard commercial temperature range.

Feature Summary

• 32 Macrocells with 36 logic blocks for flexible digital logic implementation
• Non-volatile EEPROM memory architecture enabling instant-on functionality
• Supports In-System Programmability (ISP) via JTAG interface
• Maximum operating frequency of 400 MHz with 7.5 ns typical delay

Applications

• Address decoding and bus bridging in embedded systems
• Translation between different voltage domains or logic families
• State machine implementation for control logic
• Replacement for legacy discrete logic gates in space-constrained designs

Procurement Notes

Verify the specific suffix 'ZC' against official Lattice documentation to confirm it denotes the commercial temperature grade variant. Ensure that the required programming hardware, such as the PN-T48 socket adapter, is compatible with the target desktop programmer model before procurement.

Selection Notes

Select this component when non-volatile configuration is required to eliminate external flash memory dependencies. The 400 MHz performance ceiling suits moderate-speed synchronous designs. Verify that the 48-pin TQFP footprint aligns with the PCB layout constraints and that the 32 available I/O pins meet the interface requirements.

Part Context

This part belongs to the ispMACH 4000ZE series, which integrates high-performance CPLD logic with fast, non-volatile EEPROM technology. This family is engineered to replace complex gate arrays and PALs, offering higher density and lower power consumption compared to previous generations while maintaining ease of use through ISP capabilities.

Replacement Considerations

Direct pin-to-pin replacements within the same package may include other variants from the LC4032V or LC4032ZE series, provided the speed grade and temperature rating match the design requirements. Cross-referencing the specific logic block count and I/O distribution is necessary to ensure functional equivalence.
