FAQ
What is the maximum operating frequency of the R5F61653RN50FPV?
The R5F61653RN50FPV supports a maximum CPU clock frequency of 50 MHz. This is achieved using the on-chip clock pulse generator (CPG) with an external crystal or clock source applied to the CLKIN pin. The device does not require an external PLL; internal frequency multiplication is handled by the CPG's prescaler and divider circuits. At 50 MHz, the R5F61653RN50FPV delivers single-cycle instruction execution in Advanced Mode, enabling tight real-time control loops.
Does the R5F61653RN50FPV include on-chip debug support?
Yes, the R5F61653RN50FPV integrates an on-chip debugging interface compliant with the Renesas E10A-USB and E20 emulators. It supports full hardware breakpoints, watchpoints, and real-time trace via the dedicated debug port (TCK/TMS/TDO/TDI pins). This allows non-intrusive firmware validation, live register inspection, and step-through debugging without requiring external JTAG adapters beyond standard Renesas tools.
What is the endurance rating of the on-chip data flash in the R5F61653RN50FPV?
The R5F61653RN50FPV includes 4 KB of on-chip data flash rated for 10,000 write/erase cycles with built-in ECC for bit-error correction. Each write operation requires sector erasure (512-byte minimum), and the data flash supports byte-level programming after erase. This specification is validated per Renesas' H8SX/1653R Group reliability testing and is documented in the device's Electrical Characteristics section.
Can the R5F61653RN50FPV operate from a 3.3 V supply without level-shifting for I/O?
Yes, the R5F61653RN50FPV is specified for 3.0 V to 3.6 V operation, making it fully compatible with standard 3.3 V logic families. All general-purpose I/O pins are 5 V tolerant only in input mode; output levels swing rail-to-rail within the VCC range. No external level shifters are needed when interfacing with 3.3 V peripherals, though pull-up resistors should be referenced to VCC (not 5 V) to avoid latch-up.
Is the R5F61653RN50FPV pin-compatible with other devices in the H8SX/1653R Group?
Yes, the R5F61653RN50FPV shares identical pin assignment, package dimensions, and electrical characteristics with other 100-pin LQFP variants in the H8SX/1653R Group-including R5F61653MN50FPV and R5F61653RN40FPV. Pin compatibility extends to power, reset, clock, and all peripheral signal mappings, enabling drop-in replacement across speed grade and temperature grade variants without PCB revision.
