Engineering Selection Recommendations

The MT28EW01GABA1LPC-0SIT is a direct functional equivalent for the obsolete PC28F00AM29EWLA. Selection is based on:

Identical memory capacity, organization, and parallel interface architecture
Matching voltage supply and operating temperature specifications
Identical package footprint and surface mount compatibility
Full compliance with ROHS3 and REACH requirements
Active product status with current manufacturing availability
Improved performance characteristics (95 ns access time, 60 ns write cycle time) that maintain backward compatibility with systems designed for the original 100 ns specification

Frequently Asked Questions (FAQ)

Q: Can MT28EW01GABA1LPC-0SIT be used as a direct replacement for PC28F00AM29EWLA?

A: Yes. Both parts share identical memory capacity (1Gbit), organization (128M x 8, 64M x 16), parallel interface, voltage supply (2.7V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and 64-LBGA package footprint. The substitute part has faster access and write cycle times, which are compatible with designs specified for the original part.

Q: Are there package differences between these parts?

A: No. Both parts use the 64-LBGA (11x13) package with surface mount technology. PCB layout and footprint requirements are identical.

Q: What is the product status difference?

A: The PC28F00AM29EWLA is obsolete and no longer manufactured. The MT28EW01GABA1LPC-0SIT is an active product with current manufacturing and inventory availability.

Q: Do voltage and temperature specifications match?

A: Yes. Both parts operate at 2.7V to 3.6V supply voltage and function across the -40°C to 85°C temperature range. No power supply or thermal design modifications are required.

Q: Are compliance certifications equivalent?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting identical environmental and regulatory requirements.

Q: What are the performance differences?

A: The MT28EW01GABA1LPC-0SIT has improved timing specifications: 95 ns access time versus 100 ns, and 60 ns write cycle time versus 100 ns. These faster characteristics are backward compatible with systems designed for the original part.
