LC4032B-75TN44C

Overview

The LC4032B-75TN44C is a Complex Programmable Logic Device (CPLD) from the ispMACH 4000V/B/C/Z family, manufactured by Lattice Semiconductor. It features 32 macrocells and 36 logic blocks within a 44-pin Thin Quad Flat Package (TQFP). The device supports in-system programmability via EEPROM technology and includes JTAG boundary scan capabilities. Key electrical parameters include a maximum operating frequency of 111 MHz, a propagation delay of 7.5 ns, and an I/O count of 30 lines with 2 dedicated inputs. It operates on a supply voltage range of 3.0 V to 3.6 V and functions within a commercial temperature range of 0 °C to 90 °C.

Feature Summary

• High-performance CPLD architecture with 32 macrocells and 36 logic blocks.
• In-system programmability using non-volatile EEPROM memory technology.
• Supports JTAG boundary scan for testing and debugging.
• Maximum operating frequency of 111 MHz with 7.5 ns propagation delay.

Applications

• Digital signal processing interfaces requiring high-density logic.
• System control logic for embedded processors.
• Protocol conversion and bus bridging applications.
• General-purpose digital logic replacement in industrial equipment.

Procurement Notes

Verify the specific suffix '75TN44C' against official Lattice documentation to confirm package type, speed grade, and temperature rating. Ensure compliance with RoHS standards if required by the application environment. Confirm that the design toolchain supports the ispMACH 4000V/B/C/Z family for programming and configuration.

Selection Notes

Select this component when a moderate density of logic resources (32 macrocells) is required with fast switching speeds. The TQFP-44 package is suitable for surface-mount assembly where space is constrained but through-hole options are unavailable. Consider the 3.3V/2.5V/1.8V I/O flexibility if interfacing with multiple voltage domains.

Part Context

This part belongs to the ispMACH 4000V/B/C/Z family, which offers super-fast performance and high density. The 'B' variant typically denotes specific process or feature enhancements over earlier versions like the 'V'. The family is known for supporting both 3.3V and lower voltage operations, providing versatility in system design.

Replacement Considerations

Direct replacements within the same family include LC4032B-75TN44I for industrial temperature ranges. Cross-family upgrades may involve the LC4000 series, though pinouts and logic densities must be verified. Always check for updated datasheets as older components may have end-of-life notices.
