LAMXO2280E-3TN144E

Overview

The LAMXO2280E-3TN144E is an automotive-grade Field Programmable Gate Array (FPGA) from the LA-MachXO family, qualified to AEC-Q100 standards. It features 2280 Look-Up Tables (LUTs), 7.5 Kbits of distributed RAM, and 27.6 Kbits of Embedded Block RAM (EBR). The device includes two sysCLOCK Phase Locked Loops (PLLs) for clock management and supports a maximum operating frequency of 500 MHz. It operates within a voltage range of 1.2V to 3.3V and functions across an industrial temperature range of -40°C to +125°C. Packaged in a 144-pin TQFP with 113 available I/Os, it offers instant-on capabilities without external configuration memory.

Feature Summary

• AEC-Q100 Qualified: Tested and qualified for automotive applications ensuring reliability under harsh conditions.
• Instant-On Non-Volatile Architecture: Powers up in microseconds with no external configuration memory required.
• High Logic Density: Contains 2280 LUTs, 27.6 Kbits EBR, and two PLLs for complex control and bridging tasks.
• TransFR Reconfiguration: Supports in-field logic updates while the system remains operational.

Applications

• Glue logic replacement in automotive electronic control units.
• Bus bridging and interfacing between different protocol domains.
• Power-up control and sequence management systems.
• General-purpose control logic for automotive sensors and actuators.

Procurement Notes

Verify that the specific ordering suffix corresponds to the required package and temperature grade. Confirm that the design tool version supports the LA-MachXO family for proper synthesis and place-and-route. Ensure compliance with AEC-Q100 requirements if the application mandates automotive qualification certification.

Selection Notes

Select this device when high logic density is required alongside automotive qualification. Compare against lower-density variants like the LAMXO640 if resource usage is minimal. Consider the 144-pin TQFP package constraints regarding pin count and thermal dissipation. Verify that the 1.2V core voltage requirement aligns with the system power budget.

Part Context

This component belongs to the LA-MachXO Automotive Family, designed to bridge the gap between CPLDs and low-capacity FPGAs. It combines non-volatile instant-on capabilities with FPGA flexibility. The family targets applications traditionally served by CPLDs, such as glue logic and bus interfacing, but adds reconfigurability and higher performance suitable for evolving automotive electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers migrating from other families should verify pin compatibility and logic density equivalence using official Lattice migration guides or selection tools.
