LAV-AT-X50-2CSG484I

Field Programmable Gate Array Overview

The LAV-AT-X50-2CSG484I is a high-performance CPLD from Lattice Semiconductor's MachXO2 family, designed for low-power applications requiring complex logic density. It features 50 macrocells and operates at supply voltages of 1.2V or 3.3V, ensuring compatibility with various system interfaces. The device integrates non-volatile Flash technology for instant-on functionality without external configuration memory. Key electrical parameters include a maximum operating frequency of 267 MHz and support for up to 396 I/O pins in the CQFP package variant, though this specific model utilizes a 484-ball CSBGA package. It supports JTAG debugging and offers robust security features through user-accessible encryption.

Field Programmable Gate Array Procurement Notes

Verify the exact suffix 'I' indicates industrial temperature range (-40°C to +85°C) as per official datasheets. Confirm package marking codes match the 484-ball CSBGA footprint dimensions. Ensure ordering documents specify the correct speed grade '-2' for timing compliance. Cross-reference part numbers with Lattice's current product status to avoid obsolete stock issues.

Field Programmable Gate Array Selection Notes

Select this component when instant-on capability is critical to eliminate external configuration flash requirements. Compare total power consumption against competing CPLDs if battery life is a primary constraint. Verify I/O voltage levels match the target system interfaces before finalizing the design. Consider the pin count availability in the 484-ball package relative to board space limitations.

Field Programmable Gate Array Part Context

This part belongs to Lattice's MachXO2 family, which bridges the gap between simple PLDs and complex FPGAs. It is positioned for applications needing moderate logic density with low static power consumption. The family shares common development tools like Lattice Diamond, facilitating migration within the product line. It serves as a drop-in replacement for older GALs or PALs in many legacy designs.

Field Programmable Gate Array Replacement Considerations

Direct substitutes may include other MachXO2 variants with different pin counts or speed grades. Check Lattice's cross-reference guide for equivalent logic density parts. Ensure any replacement maintains the same Flash configuration capability if instant-on is required. Verify thermal performance matches the original design constraints.
