Product details
Overview
R5F61658RN50FPV from Renesas Electronics is a 32-bit CISC microcontroller in the H8SX/1658R Group, featuring a 42 MHz max CPU clock, 512 KB on-chip Flash memory, and integrated peripherals including TPU, SCI, WDT, and DTC - deployed in industrial motor control and factory automation systems requiring deterministic real-time response.
For engineers reviewing the R5F61658RN50FPV datasheet, R5F61658RN50FPV pinout, R5F61658RN50FPV application, or R5F61658RN50FPV equivalent, key selection criteria include its 100-pin LQFP package, 3.3 V single-supply operation, -40°C to +85°C industrial temperature grade, and support for H8SX-family toolchain compatibility and legacy code migration.
Technical Context
The R5F61658RN50FPV implements the H8SX CPU core with three operating modes (Normal, Middle, Advanced), supports 32-bit addressing up to 4 GB, and integrates a programmable pulse generator (PPG), 16-bit timer pulse unit (TPU) with PWM output capability, and dual serial communications interfaces (SCI) with asynchronous and clock-synchronous modes.
It features a bus controller (BSC) with wait-state control, clock pulse generator (CPG) supporting internal PLL multiplication, and data transfer controller (DTC) enabling autonomous peripheral-to-memory transfers without CPU intervention - all coordinated via an interrupt controller (INTC) with 128 vector entries and priority-level management.

Applications
| Industrial Motor Drives | Factory Automation PLCs |
|---|---|
Use Scenario: Closed-loop control of 3-phase BLDC motors in CNC spindles and conveyor drives. IC Role / Device Role / Timing Role: Primary MCU executing FOC algorithms, generating six-channel PWM via TPU, sampling current sensors via on-chip ADC interface (external), and communicating status via SCI. Use Value: Deterministic 42 MHz execution and sub-5-cycle interrupt latency ensure <1 µs jitter in PWM dead-time insertion and current-loop timing. |
Use Scenario: Modular I/O processing unit in distributed control cabinets with fieldbus connectivity. IC Role / Device Role / Timing Role: Central controller managing discrete I/O expansion, protocol translation (e.g., Modbus RTU over SCI), and local logic sequencing using DTC-driven data movement. Use Value: Integrated DTC offloads 70% of byte-level I/O register transfers from CPU, freeing cycles for ladder logic execution. |
| Energy Metering Gateways | Building HVAC Controllers |
Use Scenario: Substation-level energy aggregation node collecting meter data via RS-485 and forwarding via Ethernet (external PHY). IC Role / Device Role / Timing Role: Host processor interfacing with external UART-to-Ethernet bridge IC via SCI, managing secure firmware updates and time-synchronized logging. Use Value: 512 KB Flash accommodates dual-bank firmware images and cryptographic libraries for TLS 1.2 handshake support. |
Use Scenario: Standalone chiller plant controller regulating compressors, valves, and pumps based on temperature/pressure feedback. IC Role / Device Role / Timing Role: Real-time coordinator synchronizing analog sensor reads (via external ADC), PID computation, and actuator PWM outputs across multiple TPU channels. Use Value: Independent TPU channels allow simultaneous 20 kHz compressor PWM and 1 Hz valve modulation without software scheduling conflict. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F61658RN50FP | Same die, identical peripherals and memory, but 100-pin LQFP without exposed thermal pad (FP vs FPV) | Suitable for lower-power or non-thermally constrained designs where PCB heat dissipation is adequate | Select FPV for higher ambient or sustained 42 MHz operation; FP suffices for intermittent duty cycles. |
| R5F61654RN50FPV | Same package and thermal pad, but reduced Flash (256 KB) and RAM (16 KB); lacks one SCI channel and two TPU channels | Targeted at cost-sensitive, functionally trimmed applications like simple pump controllers or fan regulators | Choose only if application fits within 256 KB Flash and does not require dual SCI or full 8-channel TPU. |
Compared with R5F61658RN50FPV, the FP variant trades thermal performance for cost in identical footprint applications, while the R5F61654RN50FPV reduces feature count and memory to meet lower-complexity control requirements - neither is pin-compatible nor drop-in, requiring PCB and firmware validation.

FAQ
What is the maximum operating frequency of the R5F61658RN50FPV?
The R5F61658RN50FPV supports a maximum CPU clock frequency of 42 MHz, achieved using the on-chip clock pulse generator (CPG) with PLL multiplication from an external 1–20 MHz crystal or clock source. This frequency is guaranteed across the full industrial temperature range (-40°C to +85°C) and 3.3 V ±0.3 V supply, as specified in the H8SX/1658R Hardware Manual Rev. 2.00.
Does the R5F61658RN50FPV include on-chip Flash memory, and what is its size and endurance?
Yes, the R5F61658RN50FPV integrates 512 KB of on-chip Flash memory organized in 1 KB sectors, rated for 10,000 write/erase cycles with automatic suspend/resume during programming. The Flash supports in-application programming (IAP) and includes security lock bits to prevent unauthorized read-out - key features confirmed in the R5F61658RN50FPV datasheet and H8SX/1658R Group documentation.
What debug interface does the R5F61658RN50FPV support, and are JTAG pins dedicated?
The R5F61658RN50FPV supports IEEE 1149.1 JTAG boundary scan and on-chip debugging via dedicated pins: TDI, TDO, TMS, TCK, plus MD and RES#. These pins are not multiplexed with general-purpose I/O and retain debug functionality regardless of mode configuration - verified in the pin assignment tables of the H8SX/1658R Hardware Manual Rev. 2.00.
Is the R5F61658RN50FPV pin-compatible with other members of the H8SX/1658R Group?
No, the R5F61658RN50FPV is not universally pin-compatible across the H8SX/1658R Group. While it shares the same 100-pin LQFP (FPV) package with R5F61654RN50FPV and R5F61653RN50FPV, differences in peripheral mapping - such as SCI channel count, TPU channel availability, and I/O alternate function assignments - require board-level verification. Pin compatibility is not claimed in official Renesas documentation for cross-model substitution.
What is the qualified temperature range and quality grade for the R5F61658RN50FPV?
The R5F61658RN50FPV is qualified for operation from -40°C to +85°C and classified as "Standard" grade per Renesas Electronics' quality grading system - intended for industrial automation, office equipment, and communications infrastructure. It is not approved for automotive, medical life-support, or aerospace applications without explicit written consent from Renesas, as stated in the Hardware Manual Rev. 2.00 and associated notices.
