Substitute Part Grouping Explanation

Substitution eligibility for the PC28F00AM29EWHA is determined by the following critical parameters:

Memory Capacity & Organization: Must be 1Gbit with 128M x 8 or 64M x 16 configuration
Memory Technology: Must be FLASH - NOR type with parallel interface
Voltage Compatibility: Supply voltage range must encompass 2.7V ~ 3.6V
Operating Temperature Range: Must support -40°C ~ 85°C
Package Footprint: Physical dimensions and pin count must be compatible with 64-pin BGA packages
Compliance Standards: RoHS3 compliance and MSL rating must be maintained

The MT28EW01GABA1HPC-0SIT meets all substitution criteria as an active product from the same manufacturer with identical memory specifications, voltage requirements, and thermal operating range.

Engineering Selection Recommendations

The MT28EW01GABA1HPC-0SIT is a direct functional substitute for the obsolete PC28F00AM29EWHA. Both devices share identical memory capacity, organization, interface type, voltage specifications, and thermal operating range. The substitute part offers improved performance characteristics with faster access time (95ns vs 100ns) and write cycle time (60ns vs 100ns), making it a performance-compatible replacement.

The substitute part maintains full compliance with RoHS3 and REACH standards, with equivalent MSL rating. As an active product from Micron Technology Inc., the MT28EW01GABA1HPC-0SIT provides assured long-term availability and supply chain continuity compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can MT28EW01GABA1HPC-0SIT be used as a direct replacement for PC28F00AM29EWHA?

A: Yes. Both parts are 1Gbit parallel NOR Flash devices with identical memory organization (128M x 8, 64M x 16), voltage supply range (2.7V ~ 3.6V), and operating temperature range (-40°C ~ 85°C). The substitute part is pin-compatible and functionally equivalent.

Q: What are the differences between these two parts?

A: The primary differences are product status and performance timing. PC28F00AM29EWHA is obsolete, while MT28EW01GABA1HPC-0SIT is an active product. The substitute offers faster access time (95ns vs 100ns) and write cycle time (60ns vs 100ns). Both use 64-pin BGA packages with identical 11x13mm footprints.

Q: Are the package types compatible?

A: Yes. PC28F00AM29EWHA uses 64-FBGA packaging while MT28EW01GABA1HPC-0SIT uses 64-LBGA packaging. Both are 64-pin BGA packages with the same 11x13mm physical dimensions and pin pitch, making them mechanically and electrically compatible.

Q: Does the substitute part meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. Both carry MSL rating 3 (168 Hours). Compliance certifications are equivalent.

Q: Is the faster performance of the substitute part a concern?

A: No. The substitute part's faster access and write cycle times are backward-compatible improvements. Systems designed for the original 100ns timing will operate correctly with the faster 95ns/60ns substitute part.
