LC4032V-75TN48C

Overview

The LC4032V-75TN48C 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 48-pin TQFP package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns. It supports system-in-system programmability via EEPROM technology and functions within a supply voltage range of 3.0 V to 3.6 V. The component is rated for an operating temperature range of 0°C to +90°C.

Feature Summary

• 32 Macrocells and 36 Logic Array Blocks for flexible logic implementation
• System-in-system programmability using non-volatile EEPROM technology
• High performance with 400 MHz maximum frequency and 7.5 ns typical delay
• Single power supply operation between 3.0 V and 3.6 V

Applications

• Interface bridging between different voltage domains or protocols
• Address decoding and control logic generation
• State machine implementation for sequential control
• Replacement for legacy GALs and PALs in existing designs

Procurement Notes

Verify the specific suffix 'C' against the manufacturer's current datasheet to confirm the commercial temperature grade (0°C to +90°C). Ensure the 48-TQFP package dimensions match the target PCB footprint. Confirm RoHS compliance status as indicated in the latest product specifications before finalizing procurement.

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. Consider the LA4032V variant if an extended industrial temperature range (-40°C to +125°C) is required instead of the commercial grade specified by the 'C' suffix.

Part Context

This component belongs to the Lattice ispMACH 4000V series, designed for low-power CPLD applications. It serves as a successor to older GAL devices, offering reprogrammability and higher density than standard PLDs while maintaining compatibility with traditional design flows.

Replacement Considerations

The LA4032V-75TN48E is an electrically similar alternative within the same family but typically offers an extended industrial temperature range. Verify pinout compatibility and thermal requirements when substituting.
