LFXP2-40E-5F484C

Field Programmable Gate Array Overview

The LFXP2-40E-5F484C is a member of the LatticeXP2 family, featuring 40 K logic cells and internal Flash configuration memory for instant-on operation. It includes up to 885 Kbits of sysMEM embedded block RAM and 83 Kbits of distributed RAM. The device integrates eight sysDSP blocks with 18x18 multipliers and four analog PLLs. It supports DDR/DDR2 interfaces up to 200 MHz and LVDS at 600 Mbps. Packaged in a 484-pin FineLine BGA (FBGA) with a 0.8 mm pitch, it operates within an extended temperature range.

Field Programmable Gate Array Feature Summary

• Instant-on capability via non-volatile internal Flash configuration memory
• Support for live updates using TransFR technology and secure AES encryption
• Integrated sysMEM backup functionality to preserve data during power loss
• High-performance DSP blocks optimized for multiply and accumulate operations

Field Programmable Gate Array Applications

• Industrial control systems requiring low cost and high volume
• Telecommunications infrastructure equipment
• Consumer electronics with space constraints
• Automotive display and interface applications

Field Programmable Gate Array Procurement Notes

Verify the specific suffix codes against official Lattice documentation to confirm package type, pin count, and operating temperature range. Ensure the component matches the required RoHS compliance status and lead-free specifications for your manufacturing process. Cross-reference the date code and lot number with the manufacturer's traceability records to validate authenticity and production history before integration into supply chains.

Field Programmable Gate Array Selection Notes

Select this model when system requirements demand instant-on functionality without external configuration flash. The 40 K LUT density suits moderate complexity designs needing significant embedded memory. Consider the FBGA-484 package only if board real estate allows for the associated footprint and thermal dissipation needs. Verify that the I/O voltage levels and drive strengths meet the interface specifications of connected peripherals.

Field Programmable Gate Array Part Context

This part belongs to the LatticeXP2 family, which bridges the gap between small CPLDs and larger FPGAs. It targets high-volume, cost-sensitive markets by combining FPGA flexibility with Flash-based non-volatility. The family is designed for applications where power consumption, physical size, and immediate operational readiness are critical design constraints.

Field Programmable Gate Array Replacement Considerations

Direct replacements include other devices from the LatticeXP2 family such as the LFXP2-30 or LFXP2-17, provided logic resources are sufficient. Upgrades may involve the LatticeECP3 series for higher performance or the iCE40 UltraPlus for lower power, though these require architectural adaptation.
