LC4032C-75TN44I

Overview

The LC4032C-75TN44I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 32 macrocells and 30 user I/O pins housed in a 44-pin TQFP package. The device operates on a 3.3 V supply with a maximum operating frequency of 400 MHz and a typical propagation delay of 7.5 ns. It utilizes EEPROM technology for non-volatile configuration, supporting In-System Programming (ISP). The component supports industrial temperature ranges and includes independent output enable controls for each I/O pin.

Feature Summary

• 32 Macrocells with enhanced logic capabilities
• 30 User I/O Pins with individual local OE control
• EEPROM-based non-volatile memory for ISP support
• Maximum Operating Frequency of 400 MHz

Applications

• Address decoding logic
• State machine implementation
• Bus interface bridging
• General-purpose digital logic replacement

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature range (-40°C to +85°C or +105°C depending on exact datasheet revision) against the commercial variant. Confirm the package marking and RoHS compliance status via the manufacturer's latest documentation before procurement.

Selection Notes

Select this model when 32 macrocells are sufficient for the design logic density. Ensure the 44-pin TQFP footprint matches the PCB layout. Compare against the LC4032V series if lower power consumption is required, as the 'C' variant may have different electrical characteristics compared to the 'V' series.

Part Context

This part belongs to the ispMACH 4000V/B/C/Z family of high-density PLDs. It serves as a successor to older GAL devices and offers reprogrammability advantages over fixed logic gates. The 'C' designation typically denotes a specific speed grade or temperature variant within the broader 4000V family architecture.

Replacement Considerations

Direct replacements include other parts within the LC4032V family such as LC4032V-75TN44I, provided the electrical parameters and pinout remain compatible. Verify that any substitute maintains the same EEPROM programming mechanism and voltage levels.
