LCMXO640C-3M132C Equivalent & Substitute Parts

Part Overview

The LCMXO640C-3M132C is a MachXO Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation, featuring 640 logic elements, 101 I/O pins, and a 132-LFBGA, CSPBGA package. This device is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement continuity. The substitute part maintains identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Substitute Part Grouping Explanation

The LCMXO640C-3MN132C qualifies as a direct substitute based on the following criteria:

• Identical logic element count (640 cells) and I/O configuration (101 pins)
• Matching supply voltage range (1.71V ~ 3.465V)
• Identical operating temperature range (0°C ~ 85°C)
• Same package specification (132-LFBGA, CSPBGA with 8x8 footprint)
• Equivalent MSL rating (3, 168 Hours)
• Same ECCN and HTSUS classifications

The primary distinction is product status: the original part is obsolete, while the substitute is active. The substitute also demonstrates improved compliance posture with RoHS3 certification versus non-compliance in the original part.

Parameter Comparison

Engineering Selection Recommendations

The LCMXO640C-3MN132C is the appropriate selection for new designs and procurement activities. This part maintains full electrical and mechanical compatibility with the obsolete LCMXO640C-3M132C while offering active product status and RoHS3 compliance. The transition from non-compliant to RoHS3-compliant status aligns with current regulatory requirements and supply chain standards. Both parts share identical core specifications: 640 logic elements, 101 I/O pins, 1.71V to 3.465V supply voltage range, and 132-CSPBGA (8x8) package footprint. The substitute part is available in tray packaging, supporting standard manufacturing workflows.

Frequently Asked Questions (FAQ)

Q: Can LCMXO640C-3MN132C be used as a direct replacement for LCMXO640C-3M132C?

A: Yes. Both parts are identical in logic element count (640), I/O configuration (101 pins), supply voltage range (1.71V ~ 3.465V), operating temperature (0°C ~ 85°C), and package specification (132-LFBGA, CSPBGA). The substitute is the active equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance. LCMXO640C-3M132C is obsolete and RoHS non-compliant. LCMXO640C-3MN132C is active and RoHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are the package footprints identical?

A: Yes. Both parts use the 132-CSPBGA (8x8) package with identical pin configuration and PCB footprint. No layout modifications are required for substitution.

Q: What does the "N" in LCMXO640C-3MN132C indicate?

A: The "N" designation indicates the part meets RoHS3 compliance requirements and is available in standard tray packaging, distinguishing it from the obsolete variant.

Q: Is the MSL rating the same for both parts?

A: Yes. Both parts have MSL rating 3 with a 168-hour floor life requirement. Identical moisture handling and storage protocols apply.

Q: Can I use the obsolete part if inventory is available?

A: While the obsolete part is electrically and mechanically equivalent, the active substitute is recommended for new designs and long-term supply chain stability. RoHS3 compliance of the substitute also supports regulatory alignment.
