AT25DF512C-MAHN-T Equivalent & Substitute Parts

Part Overview

The AT25DF512C-MAHN-T is a 512Kbit Serial Peripheral Interface (SPI) FLASH memory IC manufactured by Renesas Electronics Corporation. This non-volatile memory device operates at 104 MHz with a supply voltage range of 1.65V to 3.6V and is housed in an 8-UDFN (2x3) surface mount package with exposed pad. The device is currently in active production status and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications, memory organization, interface protocol, and package configuration are maintained across the product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT25DF512C-MAHN-T is determined by strict equivalence in the following parameters:

• Memory capacity: 512Kbit
• Memory organization: 64K x 8 configuration
• Interface protocol: SPI
• Clock frequency: 104 MHz operation
• Supply voltage compatibility: 1.65V ~ 3.6V range
• Package configuration: 8-UDFN (2x3) with exposed pad
• Surface mount capability
• Operating temperature range: -40°C ~ 85°C
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

The AT25XE512C-MAHN-T meets all substitution criteria as a manufacturer-recommended equivalent from Renesas Electronics Corporation.

Parameter Comparison

Engineering Selection Recommendations

Both AT25DF512C-MAHN-T and AT25XE512C-MAHN-T are active production devices from Renesas Electronics Corporation with identical compliance certifications (ROHS3, REACH Unaffected, EAR99). Both devices maintain equivalent electrical specifications for memory capacity, organization, interface protocol, clock frequency, supply voltage range, and operating temperature range. The primary difference between these parts is write cycle timing: the AT25DF512C-MAHN-T specifies 8µs word write and 4.6ms page write cycles, while the AT25XE512C-MAHN-T specifies 12µs word write and 3ms page write cycles. Selection between these parts depends on application-specific write performance requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can AT25XE512C-MAHN-T replace AT25DF512C-MAHN-T in existing designs?

A: Yes, provided the application timing requirements accommodate the AT25XE512C-MAHN-T write cycle specifications (12µs word write, 3ms page write). All other electrical and mechanical parameters are equivalent.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 8-UDFN (2x3) surface mount package with exposed pad, ensuring mechanical and thermal compatibility.

Q: What is the significance of the write cycle time difference?

A: Write cycle time affects the duration required to complete individual word or page write operations. Applications with strict timing constraints must account for these differences during design validation.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both parts operate across the -40°C to 85°C temperature range, supporting industrial grade applications.

Q: Do both parts require identical handling and storage procedures?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
