It operates at 3.0–3.6 V supply and targets industrial control systems requiring deterministic real-time response and robust peripheral integration.
For engineers reviewing the R5F61648GN50BGV datasheet, R5F61648GN50BGV pinout, R5F61648GN50BGV application, or R5F61648GN50BGV equivalent, key selection criteria include its 144-pin LQFP package, 50 MHz operation with PLL clock generation, Flash endurance (10,000 write/erase cycles), and support for single-cycle instruction execution in Advanced Mode.
Technical Context
The R5F61648GN50BGV implements the H8SX CPU core with three operating modes-Normal, Middle, and Advanced-enabling configurable performance vs. power trade-offs. Its bus controller supports external memory expansion up to 16 MB with programmable wait-state control and burst transfer capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F61648GN50BGB | Same die, 100-pin LQFP package - 44 fewer I/O pins and no TPU channel 8–15 | Limited peripheral count restricts use in multi-axis motion control or high-channel-count data acquisition | Select when board space or I/O count constraints justify reduced feature set and lower cost |
| R5F61648GN64BGV | Same functional set, 144-pin LQFP with 64 MHz max clock - higher timing margin for complex ISR chains | Enables tighter control loop deadlines (e.g., <50 µs PMSM FOC) and faster communication throughput | Choose when application requires >50 MHz deterministic timing headroom or future frequency scalability |
Compared with R5F61648GN50BGV, R5F61648GN50BGB sacrifices I/O and TPU channels for compactness, while R5F61648GN64BGV delivers higher clock headroom without architectural change - both retain identical peripheral register maps and toolchain compatibility.

FAQ
What is the maximum operating frequency of the R5F61648GN50BGV?
The R5F61648GN50BGV supports a maximum CPU clock frequency of 50 MHz, achieved via its on-chip PLL using an external 1–10 MHz crystal or clock source. This frequency is fully supported across the specified industrial temperature range (−40°C to +85°C) and supply voltage (3.0–3.6 V), enabling sub-20 ns instruction cycle times for time-critical control tasks in the R5F61648GN50BGV.
Does the R5F61648GN50BGV include on-chip debug support?
Yes, the R5F61648GN50BGV integrates an on-chip debug interface compliant with Renesas E1/E20 emulators, supporting full-speed execution, breakpoint setting, and real-time register/memory inspection. No external JTAG adapter is required - debug access uses dedicated pins (MD0/MD1) and is enabled via boot-mode configuration, making it integral to development and field diagnostics for the R5F61648GN50BGV.
What Flash memory endurance and data retention specifications apply to the R5F61648GN50BGV?
The R5F61648GN50BGV specifies 10,000 write/erase cycles for its 512 KB on-chip Flash memory, with data retention guaranteed for 20 years at +85°C or 100 years at +25°C. These values are measured per block and validated per JEDEC JESD22-A117, ensuring predictable firmware update lifetime in deployed industrial systems using the R5F61648GN50BGV.
Can the R5F61648GN50BGV operate from a 3.3 V supply without level-shifting for its I/O pins?
Yes, the R5F61648GN50BGV is designed for 3.0–3.6 V operation, and all general-purpose I/O pins are 3.3 V tolerant with TTL-compatible input thresholds. No external level shifters are needed when interfacing with standard 3.3 V logic, sensors, or communication transceivers - simplifying design and improving signal integrity in systems built around the R5F61648GN50BGV.
Is the R5F61648GN50BGV qualified for automotive applications?
No, the R5F61648GN50BGV is rated for industrial-grade operation (−40°C to +85°C) and classified as "Standard" quality per Renesas' grading system. It is not AEC-Q100 qualified, lacks automotive-specific failure-in-time (FIT) data, and does not meet requirements for safety-critical vehicle subsystems. For automotive use, Renesas recommends RH850 or RL78/F1x families instead of the R5F61648GN50BGV.
