Engineering Selection Recommendations

The AT28C64E-15PI is classified as obsolete and does not comply with RoHS requirements. Both substitute parts, AT28C64B-15PU and X28HC64PZ-12, are active and comply with ROHS3 standards. For engineering selection where RoHS compliance or product lifecycle status is mandatory, the substitutes are appropriate based solely on the data provided.

Frequently Asked Questions (FAQ)

Q1: What criteria determine a compatible substitute for the AT28C64E-15PI?
A1: Compatibility is established by matching memory size, memory organization, technology (EEPROM), interface (Parallel), voltage supply, access time, package/case type, and mounting style.

Q2: Are the substitute parts supplied in the same 28-DIP package as AT28C64E-15PI?
A2: Yes, all listed substitutes (AT28C64B-15PU, X28HC64PZ-12) utilize the 28-DIP package with the same mechanical dimensions specified.

Q3: Is there any difference in RoHS compliance between the main component and substitutes?
A3: The AT28C64E-15PI is RoHS non-compliant, while both AT28C64B-15PU and X28HC64PZ-12 are ROHS3 compliant.

Q4: Do substitute parts cover the same operating temperature range?
A4: AT28C64B-15PU matches the -40°C to 85°C range. X28HC64PZ-12 supports 0°C to 70°C.

Q5: Are electrical parameters like memory size, organization, and interface consistent among all alternatives?
A5: Yes, all substitutes provide 64Kbit memory, 8K x 8 organization, non-volatile EEPROM technology, and parallel interface functionality.
