LC4032V-75T44I

Overview

The LC4032V-75T44I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 32 macrocells and supports up to 32 I/O pins within a 44-pin TQFP package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns. It utilizes an EEPROM non-volatile memory technology for configuration storage, enabling in-system programmability. The component is designed for surface-mount installation and functions within a supply voltage range of 3.0 V to 3.6 V.

Feature Summary

• 32 Macrocells with 36 logic blocks
• In-system programmability via ISP interface
• EEPROM-based non-volatile configuration
• 400 MHz maximum operating frequency

Applications

• General-purpose digital logic replacement
• Bus protocol bridging
• Address decoding and control logic
• Simple state machine implementation

Procurement Notes

Verify the suffix 'I' indicates industrial temperature range (-40°C to +85°C) rather than commercial grade. Confirm package marking and date codes against current Lattice production notices. Ensure ESD precautions are followed during handling due to moisture sensitivity level 3 classification.

Selection Notes

Select this model when 32 macrocells are sufficient for the design complexity. The 7.5 ns speed grade offers a balance between performance and power consumption. Compare against LC4032V-5 variants if faster switching speeds are required, or LC4032V-10 variants for lower cost applications with relaxed timing constraints.

Part Context

This part belongs to the ispMACH 4000V series, which succeeded earlier ispMACH 4000 devices. The 'V' suffix denotes the specific voltage and feature set variant within the 4000 family. It serves as a drop-in replacement for legacy CPLDs in designs requiring moderate density and low power consumption.

Replacement Considerations

Direct pin-compatible substitutes include other speed grades within the LC4032V family, such as LC4032V-5T44I or LC4032V-10T44I, provided timing requirements allow. Cross-family replacements require schematic review.
