R5F100SLDFB#10 Equivalent & Substitute Parts

Part Overview

The R5F100SLDFB#10 is a 16-bit embedded microcontroller from Renesas Electronics Corporation, part of the RL78/G13 series. This device integrates 512KB of FLASH program memory, 32KB of RAM, and 8KB of EEPROM, operating at 32MHz with a supply voltage range of 1.6V to 5.5V. The microcontroller features 110 I/O pins and includes integrated connectivity options (CSI, I2C, LINbus, UART/USART) along with peripheral functions (DMA, LVD, POR, PWM, WDT). The device is housed in a 128-LFQFP surface mount package and maintains Active product status with ROHS3 compliance. Substitute parts are identified when identical electrical specifications, memory configurations, and package formats are maintained across different manufacturing batches or variant designations.

Substitute Part Grouping Explanation

Substitute parts for the R5F100SLDFB#10 are identified based on strict parametric equivalence within the RL78/G13 microcontroller family. The substitution logic is based on the following critical parameters that must remain identical:

Core Electrical Specifications:

• 16-bit RL78 core processor architecture
• 32MHz operating frequency
• 512KB FLASH program memory (512K x 8 configuration)
• 32KB RAM (32K x 8 configuration)
• 8KB EEPROM (8K x 8 configuration)
• 1.6V to 5.5V supply voltage range
• 110 I/O pins

Physical and Environmental Requirements:

• 128-LFQFP (14x20) package format
• Surface mount mounting type
• -40°C to 85°C operating temperature range
• Moisture Sensitivity Level 3 (168 Hours)

Compliance and Regulatory:

• ROHS3 compliance
• REACH Unaffected status
• Identical ECCN and HTSUS classifications

Parts designated with different suffix codes (#10, #30) represent manufacturing batch variations or packaging tray configurations that do not alter the electrical or functional characteristics of the microcontroller. All substitute parts maintain identical connectivity options (CSI, I2C, LINbus, UART/USART) and peripheral functions (DMA, LVD, POR, PWM, WDT).

Parameter Comparison

Engineering Selection Recommendations

All three parts—R5F100SLDFB#10, R5F100SLAFB#30, and R5F100SLDFB#30—are functionally equivalent and maintain Active product status from Renesas Electronics Corporation. Selection between these parts is based on availability and packaging batch designation rather than electrical or functional differences.

Compliance Considerations: All substitute parts maintain identical ROHS3 compliance, REACH Unaffected status, and regulatory classifications (ECCN: 3A991A2; HTSUS: 8542.31.0001). No compliance trade-offs exist between the main part and substitutes.

Inventory and Supply:

• R5F100SLDFB#10: 1123 Pcs available
• R5F100SLAFB#30: 1504 Pcs available
• R5F100SLDFB#30: 1103 Pcs available

Package and Handling: All parts are supplied in Tray packaging with identical Moisture Sensitivity Level 3 (168 Hours) requirements. Storage and handling protocols are uniform across all three designations.

Application Compatibility: Direct substitution is supported in all applications designed for the RL78/G13 microcontroller family with 512KB FLASH memory configuration. No firmware modifications or board-level design changes are required when switching between these parts.

Frequently Asked Questions (FAQ)

Q: Can R5F100SLAFB#30 be used as a direct replacement for R5F100SLDFB#10?

A: Yes. Both parts are parametrically equivalent RL78/G13 microcontrollers with identical core specifications, memory configuration (512KB FLASH, 32KB RAM, 8KB EEPROM), operating frequency (32MHz), I/O count (110), and 128-LFQFP package format. The suffix designation reflects manufacturing batch or packaging tray variation only.

Q: What is the difference between the #10 and #30 suffix codes?

A: The suffix codes indicate packaging batch or tray configuration designations from Renesas Electronics Corporation. These designations do not affect electrical performance, memory specifications, or functional capabilities of the microcontroller.

Q: Are all three parts suitable for the same PCB layout and footprint?

A: Yes. All three parts use the identical 128-LFQFP (14x20) surface mount package format. PCB footprints, land patterns, and assembly processes are interchangeable without modification.

Q: Do these parts require different handling or storage procedures?

A: No. All three parts maintain identical Moisture Sensitivity Level 3 (168 Hours) classification. Storage temperature, humidity control, and handling protocols are uniform across all designations.

Q: Can firmware developed for R5F100SLDFB#10 run on R5F100SLAFB#30 without modification?

A: Yes. Both parts implement the identical RL78 core processor architecture with identical memory organization and peripheral configuration. Firmware compiled for one part executes identically on the other without code changes.

Q: Are there any supply voltage or operating temperature differences between these parts?

A: No. All three parts operate across the identical voltage range (1.6V to 5.5V) and temperature range (-40°C to 85°C). Electrical specifications are fully equivalent.

Q: What connectivity and peripheral options are available on all three parts?

A: All three parts include identical connectivity interfaces (CSI, I2C, LINbus, UART/USART) and peripheral functions (DMA, LVD, POR, PWM, WDT). Integrated analog-to-digital conversion capability (26x8/10b) is present on all designations.

Q: Do these parts have different RoHS or REACH compliance status?

A: No. All three parts maintain identical ROHS3 compliance and REACH Unaffected status. Regulatory and environmental compliance is uniform across all substitute designations.
