FAQ
What is the maximum operating frequency of the R5F61642N50FPV?
The R5F61642N50FPV supports a maximum CPU clock frequency of 50 MHz when using the on-chip PLL with an external 12.5 MHz crystal (×4 multiplication). This frequency is fully supported across the full −40°C to +85°C operating range and enables sub-microsecond interrupt response times essential for motor control applications. The R5F61642N50FPV maintains timing compliance under worst-case voltage (3.0 V) and temperature conditions per its published AC characteristics.
Does the R5F61642N50FPV include on-chip debug support?
Yes, the R5F61642N50FPV integrates a full-featured on-chip debugging interface compliant with Renesas E1/E20 emulators. It supports real-time program execution control, hardware breakpoints, watchpoints, and memory/register access via the dedicated 10-pin JTAG connector (pins 119–128). This capability allows full firmware validation and field diagnostics without requiring external ICE hardware - a key advantage for R5F61642N50FPV-based industrial controllers.
What package type and thermal characteristics does the R5F61642N50FPV use?
The R5F61642N50FPV is supplied in a 128-pin LQFP package (FP-128P-M05) with an exposed thermal pad. Its junction-to-ambient thermal resistance (θJA) is 35°C/W under standard JEDEC 2-layer board conditions. The exposed pad must be soldered to a minimum 200 mm² copper pour with ≥4 thermal vias to achieve rated 1.2 W power dissipation. This thermal design is validated for continuous operation at 50 MHz in sealed industrial enclosures up to +85°C ambient.
Can the R5F61642N50FPV execute code directly from Flash memory?
Yes, the R5F61642N50FPV supports XIP (eXecute-In-Place) from its 256 KB on-chip Flash memory without requiring code copy to RAM. The Flash interface includes prefetch buffer and cache-like acceleration to sustain 50 MHz core throughput with zero wait states for sequential execution. This capability simplifies boot architecture and reduces RAM usage - a critical feature for R5F61642N50FPV deployments in resource-constrained edge controllers.
What is the Flash endurance and data retention specification for the R5F61642N50FPV?
The R5F61642N50FPV Flash memory is rated for 10,000 write/erase cycles per block and guarantees data retention of 20 years at +85°C or 100 years at +25°C. Each 1 KB sector can be erased independently, enabling robust firmware update schemes with dual-bank rollback. These specifications are verified per JEDEC JESD22-A117 and are integral to the R5F61642N50FPV qualification for industrial equipment with >10-year service life.
