Product details
Overview
R5F61664RD50FPV from Renesas Electronics is a 32-bit CISC microcontroller in the H8SX/1664R Group, featuring 256 KB on-chip Flash memory, 16 KB RAM, and a maximum operating frequency of 50 MHz. It integrates a 16-bit timer pulse unit (TPU), serial communications interface (SCI), watchdog timer (WDT), and programmable pulse generator (PPG), targeting embedded control applications requiring deterministic real-time response and integrated peripheral flexibility.
For engineers reviewing the R5F61664RD50FPV datasheet, R5F61664RD50FPV pinout, R5F61664RD50FPV application, or R5F61664RD50FPV equivalent, this device serves as a drop-in option within the H8SX/1664R family for industrial motor control, HVAC system management, and programmable logic controller (PLC) I/O modules where Flash endurance, interrupt latency, and peripheral co-processing capability are critical selection criteria.
Technical Context
The R5F61664RD50FPV implements the H8SX CPU core with three operating modes-Normal, Middle, and Advanced-supporting instruction execution at up to 50 MHz via an internal PLL clock generator. It includes a bus controller (BSC) with configurable wait-state control and external bus interface supporting 8/16-bit data width and address multiplexing.
Peripheral integration includes four independent SCI channels with asynchronous/full-duplex operation, a 16-bit TPU with input capture/output compare and PWM generation, and a data transfer controller (DTC) enabling autonomous memory-to-peripheral transfers without CPU intervention-reducing interrupt overhead in high-throughput sensor or actuator interfaces.

FAQ
What is the maximum operating frequency of the R5F61664RD50FPV?
The R5F61664RD50FPV operates at a maximum frequency of 50 MHz, achieved via its internal PLL clock pulse generator (CPG) when driven by an external crystal or oscillator in the 1–10 MHz range. This frequency is fully supported across the specified industrial temperature range (−40°C to +85°C) and 3.0–5.5 V supply voltage, and is documented in the H8SX/1664R Hardware Manual Rev.2.00.
Does the R5F61664RD50FPV support CAN bus communication?
No, the R5F61664RD50FPV does not include a built-in CAN controller or transceiver interface. Its communication peripherals consist of four SCI channels supporting asynchronous serial protocols (e.g., RS-232/485), but no CAN FD, CAN 2.0, or LIN controllers. CAN functionality requires an external transceiver and software-driven bit-banging or a companion CAN controller IC.
What package type and pin count does the R5F61664RD50FPV use?
The R5F61664RD50FPV uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) designated by the FPV suffix. This package includes dedicated power/ground pairs, separate analog and digital supply pins, and supports all primary peripherals-including TPU, SCI, PPG, and DTC-as confirmed in the H8SX/1664R Group Hardware Manual pin assignment tables.
Is the R5F61664RD50FPV qualified for automotive applications?
No, the R5F61664RD50FPV is classified as a Renesas "Standard" quality grade device, intended for industrial, office, and consumer equipment-not automotive or safety-critical systems. It lacks AEC-Q100 qualification, extended temperature support beyond +85°C, or fault-tolerant features required for automotive ECUs, as stated in Renesas' quality grade documentation.
How much on-chip Flash and RAM does the R5F61664RD50FPV provide?
The R5F61664RD50FPV integrates 256 KB of on-chip Flash memory (rated for 100,000 write/erase cycles) and 16 KB of SRAM. These memory resources are mapped into the H8SX linear address space and support in-application programming (IAP) for field firmware updates, as detailed in the R5F61664RD50FPV's memory map section of the Hardware Manual.
