Parameter Comparison

Engineering Selection Recommendations

Both the AT25XE512C-SSHN-T and AT25DF512C-SSHN-T are active production parts from Renesas Electronics Corporation with full ROHS3 compliance and REACH unaffected status. The AT25DF512C-SSHN-T carries verified programmability certification through DiGi-Electronics, whereas the AT25XE512C-SSHN-T programmability status is not verified. Both parts maintain identical electrical specifications, package dimensions, and environmental operating ranges. Selection between these parts depends on application-specific requirements regarding write cycle timing and programmability verification status.

Frequently Asked Questions (FAQ)

Q: Can the AT25DF512C-SSHN-T directly replace the AT25XE512C-SSHN-T in existing designs?

A: Yes. Both parts share identical memory capacity (512Kbit), organization (64K x 8), SPI interface, clock frequency (104 MHz), supply voltage range (1.65V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and 8-SOIC package dimensions. Pin-to-pin compatibility is maintained.

Q: What are the differences between these two parts?

A: The primary differences are write cycle timing specifications and programmability verification status. The AT25DF512C-SSHN-T offers faster word write cycle time (8µs versus 12µs) and carries DiGi-Electronics verified programmability certification. Page write cycle time differs slightly (4.6ms versus 3ms).

Q: Are both parts RoHS compliant?

A: Yes. Both the AT25XE512C-SSHN-T and AT25DF512C-SSHN-T are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the package compatibility between these parts?

A: Both parts use identical 8-SOIC surface mount packaging with 0.154" width (3.90mm). PCB footprints and reflow soldering profiles are compatible.

Q: Which part should be selected for new designs?

A: Selection criteria depend on write cycle timing requirements and programmability verification needs. The AT25DF512C-SSHN-T provides faster word write performance and verified programmability status, making it suitable for applications requiring these specifications.
