LC4032V-75TN44C

Overview

The LC4032V-75TN44C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 32 macrocells and 36 logic array blocks, housed in a 44-pin TQFP package with 30 user I/Os. The device operates at a maximum frequency of 400 MHz with a maximum propagation delay of 7.5 ns. It supports In-System Programming via EEPROM technology and functions within a commercial temperature range of 0°C to +90°C on a 3.3 V supply.

Feature Summary

• High performance: 400 MHz max frequency and 7.5 ns propagation delay
• In-System Programmability using non-volatile EEPROM memory
• Commercial temperature range operation (0°C to +90°C)
• Supports JTAG boundary scan for testing

Applications

• General-purpose digital logic replacement
• Interface bridging between different voltage domains
• State machine implementation in embedded systems

Procurement Notes

Verify RoHS compliance status as sources indicate detailed compliance data is available but not explicitly confirmed as lead-free in all summaries. Confirm Moisture Sensitivity Level (MSL 3) requirements for surface mount assembly processes. Ensure the specific suffix 'C' denotes the commercial temperature grade suitable for 0°C to +90°C operation.

Selection Notes

Select this model when 32 macrocells are sufficient for the design logic density. Choose the TN44 package for surface-mount applications requiring 30 accessible I/O pins. Verify that the 7.5 ns speed grade meets the timing constraints of the target system clock. Consider the industrial variant if operation below 0°C is required.

Part Context

This component belongs to the Lattice ispMACH 4000V series, designed for high-density, low-power CPLD applications. It serves as a successor to earlier ispMACH families, offering improved performance and flexibility through its advanced architecture while maintaining compatibility with existing development tools.

Replacement Considerations

Direct pin-compatible replacements within the same package include other members of the LC4032V family with different speed grades or temperature ratings, such as LC4032V-10TN44C. Cross-family migration may require schematic and layout adjustments.
