FAQ
What is the maximum operating frequency of the R5F61648AN50FPV?
The R5F61648AN50FPV supports a maximum CPU clock frequency of 50 MHz when operating within its specified 3.0–3.6 V supply range and −40°C to +85°C temperature envelope. This frequency is achieved using the on-chip PLL with an external crystal or clock input feeding the CPG module. The R5F61648AN50FPV maintains full peripheral functionality-including TPU, SCI, and DTC-at this speed without throttling or feature disablement.
Does the R5F61648AN50FPV include on-chip debug capability?
Yes, the R5F61648AN50FPV integrates a full on-chip debug system (OCDS) compliant with Renesas' standard debug protocol. It supports hardware breakpoints, real-time trace, and register visibility via dedicated debug pins (BKGD, TRST, etc.). This enables non-intrusive firmware validation and field diagnostics without requiring external emulators-critical for validating R5F61648AN50FPV-based control logic in safety-critical deployments.
What package type and pin count does the R5F61648AN50FPV use?
The R5F61648AN50FPV is supplied in a 144-pin LQFP package measuring 20 mm × 20 mm with 0.5 mm lead pitch. This package provides full access to all integrated peripherals-including 16 TPU channels, 4 SCI interfaces, external bus signals (AD0–AD15), and 128 general-purpose I/O pins-and is qualified for industrial reflow soldering per J-STD-020 MSL3 guidelines.
How much Flash memory does the R5F61648AN50FPV have, and what is its endurance rating?
The R5F61648AN50FPV contains 512 KB of on-chip Flash memory rated for 10,000 write/erase cycles under standard industrial conditions (3.3 V, 25°C). This endurance specification is verified per Renesas' qualification testing and supports frequent firmware updates in field-deployed R5F61648AN50FPV systems such as remote diagnostic gateways and adaptive motor controllers.
Is the R5F61648AN50FPV suitable for automotive applications?
No-the R5F61648AN50FPV is classified as a "Standard" quality grade device per Renesas' product categorization and is intended for industrial, office, and consumer equipment-not automotive or safety-critical transportation systems. Its qualification excludes AEC-Q100 stress testing and automotive temperature range (−40°C to +125°C); for automotive use, Renesas recommends RH850 or RL78/F1x series instead of the R5F61648AN50FPV.
