R5F104FHAFP#10 Equivalent & Substitute Parts

Part Overview

The R5F104FHAFP#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 192KB of FLASH program memory, 8KB EEPROM, and 20KB RAM. The microcontroller features 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 industrial temperature range of -40°C to 85°C.

The R5F104FHAFP#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. Substitute identification ensures design continuity when primary part availability is constrained.

Substitute Part Grouping Explanation

Substitute parts for the R5F104FHAFP#10 are identified through parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following matching criteria:

Core Processor Architecture: Both the main part and substitute maintain the RL78 core processor within the RL78/G14 series, ensuring instruction set compatibility and firmware portability.

Memory Configuration: Identical program memory capacity (192KB FLASH), EEPROM size (8K x 8), and RAM allocation (20K x 8) guarantee functional equivalence in code storage and runtime data handling.

Operating Specifications: Matching clock speed (32MHz), supply voltage range (1.6V ~ 5.5V), and temperature operating range (-40°C ~ 85°C) confirm electrical interchangeability.

Peripheral Integration: Identical connectivity interfaces (CSI, I2C, LINbus, UART/USART) and peripheral features (DMA, LVD, POR, PWM, WDT) ensure functional feature parity.

Package and I/O: Both parts utilize the 44-LQFP (10x10) surface mount package with 31 I/O pins, providing mechanical and pinout compatibility.

Compliance and Certification: Both parts maintain ROHS3 compliance, identical MSL rating (3), and matching REACH and ECCN classifications.

The substitute part R5F104FHAFP#30 differs only in packaging designation (tray variant), representing a distribution channel variant rather than a functional or electrical difference.

Parameter Comparison

Engineering Selection Recommendations

The R5F104FHAFP#30 is a direct parametric equivalent to the R5F104FHAFP#10. Both parts maintain Active product status within the Renesas RL78/G14 microcontroller family and carry identical ROHS3 compliance certification. The parts are functionally interchangeable across all electrical, memory, peripheral, and package specifications.

Selection between these parts is determined by packaging and supply chain considerations rather than technical performance criteria. The R5F104FHAFP#10 and R5F104FHAFP#30 designations reflect distribution packaging variants (tray configurations), with no impact on device functionality, performance, or reliability characteristics.

Both parts satisfy identical design requirements for 16-bit embedded applications requiring 192KB FLASH memory, 32MHz operation, and industrial temperature range operation. Inventory availability and procurement lead times are the primary factors influencing part selection between these equivalent options.
