LAMXO640E-3TN144E

Overview

The LAMXO640E-3TN144E is an automotive-grade Field Programmable Gate Array (FPGA) from the LA-MachXO family, qualified to AEC-Q100 standards. It features 640 Look-Up Tables (LUTs), 6 Kbits of distributed RAM, and supports a maximum operating frequency of 500 MHz. The device operates within a voltage range of 1.71 V to 3.465 V and includes 113 I/O pins in a TQFP-144 package. Designed for instant-on applications, it utilizes non-volatile memory for configuration without external components.

Feature Summary

• AEC-Q100 Qualified: Tested and qualified for automotive reliability requirements.
• Non-Volatile Architecture: Provides instant-on capability with no external configuration memory required.
• TransFR™ Technology: Enables in-field logic updates while the system remains operational.
• Flexible I/O Support: Includes sysIO buffers compatible with LVCMOS, LVTTL, PCI, LVDS, and other standards.

Applications

• Glue logic replacement
• Bus bridging and interfacing
• Power-up control systems
• Control logic implementation

Procurement Notes

Verify the specific suffix 'C' against the manufacturer's current documentation to confirm if it denotes a commercial temperature grade variant or a specific packaging option, as datasheet naming conventions may vary. Ensure the design tool version supports the LA-MachXO family for proper synthesis and place-and-route operations.

Selection Notes

Select this component when AEC-Q100 qualification is mandatory for the target application. The 640 LUT density is suitable for moderate complexity control tasks. Verify that the TQFP-144 package dimensions fit the PCB layout constraints and that the 113 available I/O pins meet the interface requirements.

Part Context

This part belongs to the LA-MachXO Automotive Family, which combines CPLD-like instant-on capabilities with FPGA flexibility. The family is optimized for applications traditionally addressed by low-capacity FPGAs and CPLDs, offering high security and reconfigurability on a single chip.
