R5F100SLAFB#10 Equivalent & Substitute Parts

Part Overview

The R5F100SLAFB#10 is a 16-bit embedded microcontroller from Renesas Electronics Corporation, part of the RL78/G13 series. This Surface Mount device integrates 512KB FLASH program memory, 32KB RAM, and 8KB EEPROM within a 128-LFQFP package. The microcontroller operates at 32MHz with a supply voltage range of 1.6V to 5.5V and includes integrated connectivity interfaces (CSI, I2C, LINbus, UART/USART) and peripheral functions (DMA, LVD, POR, PWM, WDT). The device maintains Active product status and is ROHS3 compliant. Substitute parts are identified to provide design flexibility when the primary part number becomes unavailable or when inventory requirements necessitate alternative sourcing from the same product family.

Substitute Part Grouping Explanation

Substitute parts for the R5F100SLAFB#10 are identified based on parametric equivalence within the RL78/G13 microcontroller family. Substitution is valid when all critical electrical and mechanical parameters remain identical across the device variants. The following parameters determine substitution eligibility:

Core Electrical Parameters:

• Core Processor: RL78
• Core Size: 16-Bit
• Speed: 32MHz
• Program Memory: 512KB FLASH
• RAM: 32K x 8
• EEPROM: 8K x 8
• Voltage Supply: 1.6V ~ 5.5V
• Data Converters: A/D 26x8/10b
• Number of I/O: 110
• Connectivity: CSI, I2C, LINbus, UART/USART
• Peripherals: DMA, LVD, POR, PWM, WDT
• Operating Temperature: -40°C ~ 85°C

Mechanical Parameters:

• Mounting Type: Surface Mount
• Package / Case: 128-LQFP
• Supplier Device Package: 128-LFQFP (14x20)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)
• REACH Status: REACH Unaffected

The identified substitutes R5F100SLAFB#30 and R5F100SLDFB#30 maintain complete parametric alignment with the primary part number across all electrical, mechanical, and compliance specifications. Differences in part number suffixes (#10, #30) reflect packaging tray configurations and do not alter functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—R5F100SLAFB#10, R5F100SLAFB#30, and R5F100SLDFB#30—are functionally equivalent and maintain Active product status from Renesas Electronics Corporation. Each device is ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory requirements for embedded microcontroller applications.

Selection between these part numbers is determined by packaging tray configuration and inventory availability rather than functional or electrical differences. The suffix designation (#10 or #30) indicates the specific tray packaging variant supplied by the manufacturer. All three variants are suitable for direct substitution in designs requiring a 16-bit RL78 microcontroller with 512KB FLASH memory, 32KB RAM, and the specified peripheral feature set.

The 128-LFQFP (14x20) package format is consistent across all variants, ensuring identical PCB footprint and assembly compatibility. Moisture Sensitivity Level 3 (168 Hours) applies uniformly, requiring standard handling and storage protocols for all three part numbers.

Frequently Asked Questions (FAQ)

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

A: Yes. Both part numbers are parametrically equivalent RL78/G13 microcontrollers with identical electrical specifications, memory configuration, peripheral set, and 128-LFQFP package format. The suffix difference (#10 versus #30) reflects packaging tray configuration only and does not affect device functionality or performance.

Q: What is the difference between R5F100SLAFB#30 and R5F100SLDFB#30?

A: Both devices are parametrically equivalent with identical core processor, memory, speed, connectivity, and peripheral specifications. The difference in the part number designation (SLA versus SLD) reflects internal Renesas product line categorization but does not result in functional or electrical differences relevant to circuit design or application performance.

Q: Are all three part numbers compatible with the same PCB layout?

A: Yes. All three part numbers use the 128-LFQFP (14x20) package format with 110 I/O pins in identical pin configuration. PCB footprint, trace routing, and assembly processes are interchangeable across R5F100SLAFB#10, R5F100SLAFB#30, and R5F100SLDFB#30.

Q: Do these microcontrollers require different firmware or programming procedures?

A: No. All three part numbers are based on the same RL78 core processor architecture with identical instruction set, memory organization, and peripheral register mapping. Firmware developed for one part number executes identically on the others without modification.

Q: What is the significance of the Moisture Sensitivity Level 3 rating?

A: MSL 3 (168 Hours) indicates the device can be exposed to ambient conditions of 30°C and 85% relative humidity for up to 168 hours before soldering without risk of moisture-induced defects. Standard handling, storage, and assembly protocols for MSL 3 components apply uniformly to all three part numbers.

Q: Are there any compliance or certification differences between these part numbers?

A: No. All three devices carry identical ROHS3 compliance and REACH unaffected status. Environmental and regulatory certifications are uniform across R5F100SLAFB#10, R5F100SLAFB#30, and R5F100SLDFB#30.

Q: Can these microcontrollers operate across the full -40°C to 85°C temperature range?

A: Yes. All three part numbers are rated for operation across the -40°C to 85°C (TA) temperature range with identical electrical performance specifications maintained throughout this range.

Q: What supply voltage range is supported by these devices?

A: All three microcontrollers operate with a supply voltage range of 1.6V to 5.5V (Vcc/Vdd). This wide voltage range supports both low-power battery-operated applications and standard 3.3V or 5V logic level systems.
