Product details
Overview
R5F61635D50FPV from Renesas Electronics is a 32-bit CISC microcontroller in the H8SX/1635 Group, featuring a 50 MHz maximum CPU clock, 512 KB on-chip Flash memory, and integrated peripherals including TPU, SCI, WDT, and DTC. It operates from a 3.0–3.6 V supply and targets industrial control and motor drive applications requiring deterministic real-time response.
For engineers reviewing the R5F61635D50FPV datasheet, R5F61635D50FPV pinout, R5F61635D50FPV application, or R5F61635D50FPV equivalent, key selection criteria include its 144-pin LQFP package, 50 MHz operation with 3.3 V core logic, Flash endurance of 10,000 write/erase cycles, and support for single-cycle instruction execution in Advanced Mode.
Technical Context
The R5F61635D50FPV implements the H8SX CPU core with three operating modes-Normal, Middle, and Advanced-enabling configurable performance vs. power trade-offs. It integrates a programmable pulse generator (PPG), 16-bit timer pulse unit (TPU) with 16 channels, and dual serial communication interfaces (SCI) supporting asynchronous and clock-synchronous protocols.
Its system architecture includes a bus controller (BSC) with wait-state control, clock pulse generator (CPG) supporting PLL-based frequency multiplication, and data transfer controller (DTC) for autonomous peripheral-to-memory transfers without CPU intervention-reducing interrupt overhead in high-throughput I/O scenarios.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F61635D60FPV | Same pinout and peripheral set, rated for 60 MHz max clock (vs. 50 MHz); higher power consumption at full speed | Required where loop bandwidth exceeds 25 kHz or multi-axis coordination demands tighter timing margins | Select when design requires >50 MHz deterministic timing headroom; verify thermal dissipation in 144-LQFP |
| R5F61633D50FPV | Identical package and clock rating, but reduced Flash (256 KB) and RAM (16 KB); lacks second SCI channel | Suitable for cost-sensitive single-protocol systems (e.g., standalone motor driver without diagnostics port) | Choose for simplified BOM where dual-SCI or large firmware image is unnecessary; no PCB change required |
Compared with R5F61635D50FPV, the R5F61635D60FPV offers higher compute headroom at the cost of thermal load, while the R5F61633D50FPV trades memory and interface depth for lower unit cost-both retain identical pinout, peripheral register maps, and toolchain compatibility.

FAQ
What is the maximum operating frequency of the R5F61635D50FPV?
The R5F61635D50FPV operates at a maximum CPU clock frequency of 50 MHz when powered at 3.3 V and within its specified temperature range. This frequency is achieved using the on-chip PLL with an external 1–10 MHz crystal or clock source. The R5F61635D50FPV maintains full peripheral functionality-including TPU, SCI, and ADC-at this speed, with timing validated per Renesas Hardware Manual Rev.2.00.
Does the R5F61635D50FPV support in-system programming (ISP)?
Yes, the R5F61635D50FPV supports in-system programming via its on-chip Flash memory using the dedicated FLCTL module and standard SCI bootloader protocol. Firmware updates can be performed through a single SCI interface without removing the R5F61635D50FPV from the target board, provided the application reserves protected boot-sector space and adheres to Renesas' Flash write/erase timing requirements.
What package type does the R5F61635D50FPV use?
The R5F61635D50FPV uses a 144-pin LQFP package with 0.5 mm lead pitch and a 20 mm × 20 mm body size (suffix FPV). It features an exposed thermal pad on the underside for enhanced heat dissipation, though the pad is electrically isolated and not connected to any internal ground or power plane. This package is compatible with standard reflow profiles for lead-free assembly.
How many serial communication interfaces does the R5F61635D50FPV integrate?
The R5F61635D50FPV integrates two independent Serial Communication Interface (SCI) modules, each supporting asynchronous (UART) and clock-synchronous (SPI-like) modes. Both SCIs feature programmable baud rates, framing error detection, and separate transmit/receive interrupt vectors-enabling simultaneous use for host communication and peripheral daisy-chaining without resource contention in the R5F61635D50FPV.
Is the R5F61635D50FPV qualified for automotive applications?
No, the R5F61635D50FPV is classified as a Standard-grade Renesas product intended for industrial applications such as PLCs, motor drives, and test equipment-not for automotive use. It lacks AEC-Q100 qualification, extended temperature range (−40°C to +125°C), or automotive-specific failure-in-time (FIT) data. For automotive designs, Renesas recommends the RH850 or RL78/F1x families instead of the R5F61635D50FPV.
