DF38102FPV Equivalent & Substitute Parts

Part Overview

The DF38102FPV is an 8-bit microcontroller from Renesas Electronics Corporation, part of the H8® H8/300L SLP series. This device integrates 16KB of FLASH program memory, 1KB of RAM, and operates at 10MHz with a supply voltage range of 1.8V to 5.5V. The component is housed in a 64-LFQFP (10x10) surface mount package and is currently in active production status with ROHS3 compliance and REACH unaffected classification.

Finding equivalent or substitute parts becomes necessary when addressing supply chain constraints, design optimization requirements, or when transitioning to enhanced processor architectures while maintaining similar peripheral functionality and package compatibility.

Substitute Part Grouping Explanation

The R5F10WLAAFB#30 qualifies as a substitute based on the following alignment criteria:

Common Parameters:

• Manufacturer: Renesas Electronics Corporation (same source)
• Package: 64-LFQFP (10x10) identical physical form factor
• Program Memory: 16KB FLASH (16K x 8) matching capacity
• RAM Size: 1K x 8 identical configuration
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Product Status: Active

Architectural Differences: The R5F10WLAAFB#30 represents an upgrade path within the Renesas embedded microcontroller portfolio, transitioning from the H8/300L 8-bit architecture to the RL78 16-bit architecture. This substitution is valid for applications where the enhanced processing capability and extended feature set do not conflict with existing design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the DF38102FPV and R5F10WLAAFB#30 maintain active production status with identical RoHS3 compliance and REACH unaffected classification, ensuring regulatory alignment for current and future applications.

The DF38102FPV remains the primary choice for designs requiring the H8/300L 8-bit architecture with established firmware and peripheral integration specific to this processor family.

The R5F10WLAAFB#30 serves as a substitute when design requirements permit architectural migration to the RL78 16-bit platform. This transition offers increased processing speed (24MHz versus 10MHz), expanded I/O capability (42 versus 39 pins), enhanced analog conversion (9x10-bit versus 4x10-bit), and extended connectivity options (CSI, I2C, LINbus, UART/USART versus SCI). The identical 64-LFQFP package footprint and matching program memory capacity (16KB FLASH) facilitate PCB-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the R5F10WLAAFB#30 be used as a direct pin-for-pin replacement?

A: Both devices share the identical 64-LFQFP (10x10) package form factor and footprint. However, pin functionality differs between the H8/300L and RL78 architectures. A direct substitution requires firmware recompilation and validation of peripheral mapping to confirm functional compatibility with the target application.

Q: What are the key differences in memory configuration?

A: Both parts provide 16KB FLASH program memory and 1KB RAM. The R5F10WLAAFB#30 includes an additional 4KB x 8 EEPROM, which the DF38102FPV does not specify. This additional storage capacity may benefit applications requiring non-volatile data retention beyond program memory.

Q: How do the operating temperature ranges differ?

A: The DF38102FPV operates from -20°C to 75°C, while the R5F10WLAAFB#30 extends this range to -40°C to 85°C. Applications requiring operation at lower temperatures or in thermally demanding environments benefit from the R5F10WLAAFB#30's extended specification.

Q: Are both devices suitable for low-voltage applications?

A: The DF38102FPV supports 1.8V minimum supply voltage, while the R5F10WLAAFB#30 operates at 1.6V minimum. Both devices accommodate the full 5.5V maximum specification, making them suitable for battery-powered and regulated supply applications within their respective voltage windows.

Q: What connectivity advantages does the R5F10WLAAFB#30 provide?

A: The R5F10WLAAFB#30 integrates CSI, I2C, LINbus, and UART/USART connectivity, compared to the DF38102FPV's SCI interface. This expanded connectivity suite enables integration with a broader range of peripheral devices and communication protocols without requiring external interface controllers.

Q: Do both parts maintain identical compliance certifications?

A: Yes. Both the DF38102FPV and R5F10WLAAFB#30 are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment for applications subject to these environmental and hazardous substance restrictions.
