LC4032V-75T48E

Overview

The LC4032V-75T48E 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 48-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, allowing for in-system programmability. The component is designed for surface-mount installation and functions within a standard commercial temperature range.

Feature Summary

• High-speed performance with 400 MHz maximum operating frequency
• EEPROM-based non-volatile configuration for instant power-up readiness
• Supports In-System Programmability (ISP) via JTAG interface
• 32 Macrocells providing flexible logic implementation

Applications

• Address decoding and bus bridging in embedded systems
• Translation between different voltage domains or logic families
• State machine implementation for control logic
• Replacement for legacy discrete logic gates

Procurement Notes

Verify the suffix 'E' against official Lattice documentation to confirm specific environmental or lead-free compliance status, as distributor listings may vary. Ensure the ordering part number matches the exact speed grade (-75) and package type (TQFP-48). Confirm moisture sensitivity level handling requirements during storage and assembly processes.

Selection Notes

Select this model when a moderate density CPLD with fast switching speeds is required. The 32 macrocell count suits simple control applications. Compare against the LA4032V series if automotive qualification (AEC-Q100) or extended temperature ranges are necessary, as the 'V' series typically denotes commercial grade specifications.

Part Context

This component belongs to the Lattice ispMACH 4000V family, which bridges the gap between low-density PLDs and high-density FPGAs. The family is characterized by its use of EEPROM technology, offering reprogrammability without the volatility associated with SRAM-based FPGAs. It serves as a drop-in replacement for many complex gate array applications.

Replacement Considerations

Direct pin-compatible alternatives within the same package include other members of the ispMACH 4000V family with similar macrocell counts. Verify that any substitute maintains the 7.5 ns speed grade and 3.3V I/O compatibility to ensure signal integrity in existing designs.
