Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF36014GFYV is evaluated based on the following critical parameters:

• Package Compatibility: Both parts must use 48-LQFP (7x7) surface mount packaging to ensure PCB layout compatibility
• Voltage Supply Range: Substitute parts must operate within or encompass the 3V to 5.5V supply range
• I/O Pin Count: Minimum 30 I/O pins required for functional equivalence
• Program Memory: Minimum 32KB FLASH memory to support existing firmware
• Compliance Standards: RoHS3 compliance and MSL rating of 3 or better required
• Manufacturer: Renesas Electronics Corporation parts maintain design consistency and support continuity

The R5F523T3ADFL#30 qualifies as a substitute based on matching package type, exceeding memory specifications, maintaining voltage compatibility, and meeting all compliance requirements.

Engineering Selection Recommendations

The R5F523T3ADFL#30 is qualified as a direct substitute for the DF36014GFYV based on the following engineering criteria:

• Package Compatibility: Identical 48-LQFP (7x7) surface mount package ensures no PCB redesign is required
• Voltage Compliance: The substitute's 2.7V to 5.5V supply range encompasses the original 3V to 5.5V specification
• Memory Sufficiency: 64KB FLASH and 10KB RAM exceed the original 32KB FLASH and 2KB RAM, providing additional headroom for firmware expansion
• I/O Availability: 35 I/O pins exceed the required 30 pins, maintaining full functional compatibility
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring manufacturing and storage compatibility
• Product Status: Both parts are in active production with confirmed inventory availability
• Temperature Range: The substitute's extended operating temperature range (-40°C to 85°C) provides broader environmental coverage compared to the original (-20°C to 75°C)

Frequently Asked Questions (FAQ)

Q: Can the R5F523T3ADFL#30 be used as a direct replacement without PCB modifications?

A: Yes. Both parts use identical 48-LQFP (7x7) surface mount packaging with the same pin pitch and footprint, eliminating the need for PCB layout changes.

Q: What are the key differences between the DF36014GFYV and R5F523T3ADFL#30?

A: The substitute features a 32-bit processor architecture versus the original 16-bit design, operates at 40MHz instead of 20MHz, includes double the FLASH memory (64KB vs 32KB), and provides five additional I/O pins (35 vs 30). Both maintain identical package form factors and compliance certifications.

Q: Is firmware compatibility guaranteed when switching to the R5F523T3ADFL#30?

A: Firmware compatibility depends on application-specific code. While the substitute provides superior memory and processing capabilities, architectural differences between the H8/300H and RX processor families require code review and potential recompilation. Existing H8/300H assembly code may require adaptation.

Q: Are there any supply voltage considerations when using the substitute?

A: The substitute operates at 2.7V minimum versus the original 3V minimum. Applications designed for 3V to 5.5V operation remain fully compatible. The extended lower voltage limit provides additional design flexibility for battery-powered applications.

Q: Do both parts meet the same compliance and moisture sensitivity requirements?

A: Yes. Both parts are ROHS3 compliant with MSL rating 3 (168 Hours), ensuring identical manufacturing, storage, and handling requirements.

Q: What is the inventory status for both parts?

A: The DF36014GFYV has 819 units in stock. The R5F523T3ADFL#30 has 1570 units in stock, providing greater availability for high-volume production requirements.
