R5F104FFAFP#10 Equivalent & Substitute Parts

Part Overview

The R5F104FFAFP#10 is a 16-bit embedded microcontroller from Renesas Electronics Corporation, part of the RL78/G14 series. This device integrates a RL78 core processor operating at 32MHz with 96KB of FLASH program memory, 12KB of RAM, and 8KB of EEPROM. The microcontroller provides 31 I/O pins and supports multiple communication interfaces including CSI, I2C, LINbus, and UART/USART, along with integrated peripherals such as DMA, LVD, POR, PWM, and WDT. The device is housed in a 44-LQFP surface mount package and operates across a supply voltage range of 1.6V to 5.5V with an operating temperature range of -40°C to 85°C.

The R5F104FFAFP#10 maintains Active product status and carries ROHS3 compliance certification. Equivalent substitute parts are identified based on matching electrical specifications, memory configurations, peripheral sets, and package form factors to ensure direct functional interchangeability in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R5F104FFAFP#10 are identified through strict parametric matching across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Core Processor Architecture: Both the main part and substitute must utilize the RL78 core processor to ensure instruction set compatibility and firmware portability.

Memory Configuration: Substitute parts must provide identical program memory capacity (96KB FLASH), EEPROM size (8K x 8), and RAM allocation (12K x 8) to maintain software compatibility without modification.

Operating Specifications: Clock speed (32MHz), supply voltage range (1.6V ~ 5.5V), and operating temperature range (-40°C ~ 85°C) must be identical to ensure functional equivalence in the target application.

Peripheral Set: All communication interfaces (CSI, I2C, LINbus, UART/USART) and integrated peripherals (DMA, LVD, POR, PWM, WDT) must be present and functionally identical.

I/O Configuration: The number of I/O pins (31) and pin assignment must match to ensure direct PCB compatibility without redesign.

Package Form Factor: The 44-LQFP (10x10) surface mount package must be identical to allow direct component substitution on existing circuit boards.

Compliance and Certification: RoHS3 compliance and MSL rating (3, 168 Hours) must be maintained across all substitute parts.

The only variable parameter across substitute parts is the packaging designation suffix (e.g., #10 versus #30), which indicates different packaging quantities or tape/reel configurations from the manufacturer but does not affect electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the R5F104FFAFP#10 and R5F104FFAFP#30 are functionally equivalent microcontroller units with identical electrical specifications, memory configurations, peripheral sets, and package form factors. Selection between these parts is determined by supply chain availability and packaging quantity requirements rather than technical performance differences.

The R5F104FFAFP#10 is suitable for applications requiring standard packaging quantities, while the R5F104FFAFP#30 designation indicates alternative packaging configuration from the same manufacturer. Both parts maintain Active product status and carry ROHS3 compliance certification, ensuring long-term availability and regulatory compliance for industrial, automotive, and consumer embedded applications.

Direct substitution between R5F104FFAFP#10 and R5F104FFAFP#30 requires no circuit board redesign, firmware modification, or application software changes. Pin assignments, electrical characteristics, and functional behavior remain identical across both part numbers.

Frequently Asked Questions (FAQ)

Q: Can R5F104FFAFP#30 be used as a direct replacement for R5F104FFAFP#10 on existing circuit boards?

A: Yes. Both parts are electrically and mechanically identical. The suffix designation (#10 versus #30) reflects packaging quantity or tape/reel configuration only and does not affect pin assignment, electrical performance, or functional operation. Direct PCB substitution is possible without component relocation or circuit modification.

Q: Are the memory configurations identical between R5F104FFAFP#10 and R5F104FFAFP#30?

A: Yes. Both parts provide 96KB of FLASH program memory, 12KB of RAM, and 8KB of EEPROM. Firmware compiled for one part number executes identically on the other without modification.

Q: Do both part numbers support the same communication interfaces?

A: Yes. Both R5F104FFAFP#10 and R5F104FFAFP#30 include CSI, I2C, LINbus, and UART/USART connectivity, along with identical peripheral support (DMA, LVD, POR, PWM, WDT).

Q: What is the significance of the packaging suffix in the part number?

A: The suffix (#10 or #30) indicates the manufacturer's packaging designation, typically related to tape/reel quantity or distribution channel. This does not affect the die, electrical specifications, or functional performance of the microcontroller.

Q: Are both parts RoHS compliant?

A: Yes. Both R5F104FFAFP#10 and R5F104FFAFP#30 carry ROHS3 compliance certification and are suitable for applications requiring regulatory compliance in restricted substance use.

Q: What is the MSL rating for these microcontrollers?

A: Both parts carry an MSL rating of 3 with a 168-hour moisture sensitivity window. Standard moisture control procedures during storage and handling are required to maintain component reliability.

Q: Can firmware be transferred between R5F104FFAFP#10 and R5F104FFAFP#30 without recompilation?

A: Yes. Since both parts share identical core processor architecture, memory configuration, and peripheral sets, compiled firmware is directly portable between the two part numbers without modification or recompilation.
