LAMXO1200E-3TN100E

Overview

The LAMXO1200E-3TN100E is an automotive-grade Field Programmable Gate Array (FPGA) from the LA-MachXO family, qualified to AEC-Q100 standards. It features 1200 Look-Up Tables (LUTs), 6.25 Kbits of distributed RAM, and one Embedded Block RAM (EBR) block providing 9.2 Kbits of SRAM. The device operates at a core voltage of 1.2V and supports up to 73 I/O pins in a 100-pin TQFP package. Key architectural elements include one sysCLOCK PLL for clock management and non-volatile Flash memory enabling instant-on configuration without external components.

Feature Summary

• AEC-Q100 Qualified: Tested and qualified for automotive applications with extended temperature ranges.
• Non-Volatile Instant-On: Internal Flash memory allows power-up in microseconds without external configuration chips.
• Flexible I/O Support: sysIO buffers support LVCMOS 1.2/1.5/1.8/2.5/3.3V, LVTTL, PCI, LVDS, and other standards.
• TransFR Reconfiguration: Enables in-field logic updates while the system remains operational.

Applications

• Glue logic replacement in automotive control units
• Bus bridging and interface translation
• Power-up control and sequence management
• General-purpose I/O expansion

Procurement Notes

Verify that the specific suffix 'E' corresponds to the intended temperature grade and packaging variant as defined in the official LA-MachXO Automotive Family Data Sheet. Confirm that the design tool version supports the specific device architecture and constraints for the TN100 package.

Selection Notes

Select this device when 1200 LUTs are required alongside AEC-Q100 qualification. Note that the E-series variants typically operate at a 1.2V core voltage, whereas C-series variants may support higher voltages; verify voltage requirements against the system design. Ensure the 100-pin TQFP package fits the PCB footprint constraints.

Part Context

This component belongs to the LA-MachXO automotive family, which bridges the gap between CPLDs and low-capacity FPGAs. It combines the non-volatile, instant-on characteristics of CPLDs with the flexible logic density and embedded memory resources typical of FPGAs, specifically tailored for rugged automotive environments.

Replacement Considerations

Cross-reference with other LA-MachXO devices such as LAMXO640E or LAMXO2280E if logic density or I/O count requirements differ. Verify pin compatibility if migrating between different package options within the same family.
