Substitute Part Grouping Explanation

The MX29GL256FUT2I-11G can be substituted with MX29GL256FLT2I-90Q based on the following criteria:

Matching Parameters (Substitution Basis):

• Memory capacity: 256Mbit
• Memory organization: 32M x 8
• Interface type: Parallel
• Technology: FLASH - NOR
• Supply voltage range: 2.7V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• Package: 56-TFSOP
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 3 (168 Hours)

Differentiating Parameter:

• Access time: MX29GL256FUT2I-11G operates at 110 ns, while MX29GL256FLT2I-90Q operates at 90 ns

The substitute part offers faster access time, making it compatible with applications designed for the original part while providing improved performance margin.

Parameter Comparison

Engineering Selection Recommendations

Both MX29GL256FUT2I-11G and MX29GL256FLT2I-90Q are active products from Macronix with identical RoHS3 compliance and REACH unaffected status. The MX29GL256FLT2I-90Q substitute provides equivalent functionality with improved access time performance (90 ns versus 110 ns), making it suitable for applications where the original part is unavailable. Both components maintain identical electrical characteristics, thermal operating range, and physical packaging, ensuring direct compatibility at the board level. Selection between these parts depends solely on availability and timing requirements, with no functional limitations introduced by substitution.

Frequently Asked Questions (FAQ)

Q: Can MX29GL256FLT2I-90Q replace MX29GL256FUT2I-11G in existing designs?

A: Yes. Both parts share identical memory capacity, organization, interface type, voltage specifications, temperature range, and physical package dimensions. The substitute part operates at faster access time (90 ns versus 110 ns), which is compatible with designs specified for the original 110 ns part.

Q: What is the primary difference between these two parts?

A: The access time and write cycle time differ. MX29GL256FUT2I-11G operates at 110 ns, while MX29GL256FLT2I-90Q operates at 90 ns. All other electrical and mechanical parameters are identical.
