LAMXO640E-3TN100E

Overview

The LAMXO640E-3TN100E is an automotive-grade Field Programmable Gate Array (FPGA) from the LA-MachXO family, designed for control and bridging applications. It features 640 Look-Up Tables (LUTs), 6.0 Kbits of distributed RAM, and supports up to 74 I/Os in a 100-pin Lead-Free TQFP package (14x14 mm). The device operates with core voltages of 1.2V, 1.8V, 2.5V, or 3.3V. Key architectural elements include non-volatile instant-on configuration, TransFR™ in-field reconfiguration, and AEC-Q100 qualification.

Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• Non-volatile architecture enabling instant-on operation without external configuration memory
• TransFR™ technology allowing in-field logic updates while the system operates
• Flexible sysIO buffers supporting LVCMOS, LVTTL, PCI, LVDS, and other interface standards

Applications

• Glue logic implementation
• Bus bridging and interfacing
• Power-up control systems
• General-purpose control logic

Procurement Notes

Verify that the specific suffix '3' corresponds to the required speed grade and temperature range as defined in the LA-MachXO Automotive Family Data Sheet DS1003. Confirm package dimensions match the 100-pin TQFP specification. Ensure design tools support the specific voltage configurations (1.2V/1.8V/2.5V/3.3V) required by the target application.

Selection Notes

Select this device when transitioning from CPLDs to FPGAs is needed for low-capacity designs requiring non-volatile storage. The LA-MachXO640E offers density migration paths within the family. Consider the EBR SRAM availability in larger devices if significant embedded memory is required, as this model relies on distributed RAM.

Part Context

This component belongs to the LA-MachXO Automotive Family, which combines CPLD-like instant-on capabilities with FPGA flexibility. The family includes devices ranging from 256 to 2280 LUTs. The LA-MachXO640E sits in the mid-range of this portfolio, providing a balance of logic density and I/O count suitable for complex control tasks.

Replacement Considerations

Within the same family, the LAMXO256E/C offers lower density (256 LUTs), while the LAMXO1200E provides higher density (1200 LUTs) and additional PLLs. Verify pin compatibility and resource requirements before substituting.
