Key Parameters

Substitute Part Grouping Explanation

The R5F10WMFAFA#30 qualifies as an equivalent substitute based on the following alignment criteria:

Matching Parameters:

• Manufacturer: Renesas Electronics Corporation (same source)
• Core Size: 16-Bit (identical processor architecture class)
• Program Memory Size: 96KB (96K x 8) (identical capacity)
• Program Memory Type: FLASH (identical memory technology)
• Mounting Type: Surface Mount (identical assembly method)
• Operating Temperature: -40°C ~ 85°C (TA) (identical range)
• Package Footprint: 80-pin QFP format (14x14mm) (mechanically compatible)
• RoHS Status: ROHS3 Compliant (identical compliance)
• Moisture Sensitivity Level: 3 (168 Hours) (identical MSL rating)

Substitution Basis: Both devices share identical program memory capacity, core bit-width, temperature range, and compliance certifications. The 80-pin QFP package format ensures mechanical and electrical pin compatibility at the board level.

Parameter Comparison

Engineering Selection Recommendations

Both the DF36049HWV and R5F10WMFAFA#30 maintain Active product status with full RoHS3 and REACH compliance. Selection between these devices should be based on application-specific requirements:

The DF36049HWV remains the primary choice for designs requiring the H8/300H architecture with established firmware compatibility and legacy system integration.

The R5F10WMFAFA#30 serves as a qualified substitute when enhanced performance specifications are acceptable, including higher clock speed (24MHz vs. 20MHz), expanded RAM (6K x 8 vs. 4K x 8), higher-resolution analog conversion (12-bit vs. 8-bit), and extended voltage supply range (1.6V ~ 5.5V vs. 3V ~ 5.5V). The RL78 architecture provides additional connectivity options (LINbus, UART/USART, CSI) and peripheral features (DMA, LCD, LVD, POR) not present in the H8/300H variant.

Both devices share identical program memory capacity, core bit-width, temperature operating range, and compliance certifications, ensuring functional equivalence at the system level.

Frequently Asked Questions (FAQ)

Q: Are DF36049HWV and R5F10WMFAFA#30 pin-compatible?

A: Both devices use 80-pin QFP packages with 14x14mm footprints. The DF36049HWV uses 80-BQFP packaging while the R5F10WMFAFA#30 uses 80-LQFP packaging. Pin-level compatibility requires verification against the specific pinout diagrams for each device, as package variant designations may indicate different pin assignments.

Q: What are the key differences in memory configuration?

A: Both devices provide identical program FLASH memory at 96KB (96K x 8). The R5F10WMFAFA#30 offers increased RAM (6K x 8 vs. 4K x 8) and includes 4K x 8 EEPROM, while the DF36049HWV does not specify EEPROM capacity. These differences may impact applications requiring extended data storage or runtime memory allocation.

Q: Can I use R5F10WMFAFA#30 in a design originally specified for DF36049HWV?

A: Substitution requires firmware compatibility assessment. The DF36049HWV uses the H8/300H architecture while the R5F10WMFAFA#30 uses the RL78 architecture. These are distinct processor families with different instruction sets, requiring code recompilation and functional validation. Electrical and thermal characteristics are compatible within the specified operating ranges.

Q: What is the difference in operating voltage ranges?

A: The DF36049HWV operates from 3V to 5.5V, while the R5F10WMFAFA#30 operates from 1.6V to 5.5V. The R5F10WMFAFA#30 supports lower voltage operation, making it suitable for battery-powered or low-voltage applications where the DF36049HWV cannot be used.

Q: How do the analog conversion capabilities compare?

A: The DF36049HWV provides 8-channel 10-bit analog-to-digital conversion. The R5F10WMFAFA#30 provides 12-channel 10-bit conversion with higher resolution capability. Applications requiring higher analog precision or additional conversion channels may benefit from the R5F10WMFAFA#30.

Q: Are both devices suitable for industrial temperature applications?

A: Both devices operate across the identical temperature range of -40°C to 85°C (TA), meeting industrial and automotive temperature specifications. Both maintain RoHS3 compliance and identical moisture sensitivity levels (MSL 3, 168 hours), ensuring equivalent reliability in harsh environments.
