Product details
Overview
R5F61664MN50FPV from Renesas Electronics is a 32-bit CISC microcontroller in the H8SX/1664M Group, featuring a 50 MHz maximum CPU clock, 512 KB on-chip Flash memory, and integrated peripherals including TPU, SCI, I²C, and WDT. It operates from a 3.0–3.6 V supply and targets industrial control and embedded automation systems requiring deterministic real-time response.
For engineers reviewing the R5F61664MN50FPV datasheet, R5F61664MN50FPV pinout, R5F61664MN50FPV application, or R5F61664MN50FPV equivalent, this page delivers verified package mapping (LQFP-100), confirmed peripheral register sets, Flash endurance (10⁴ write/erase cycles), operating temperature range (−40°C to +85°C), and validated alternative MCUs for migration paths in legacy H8SX-based designs.
Technical Context
The R5F61664MN50FPV implements the H8SX core with three operating modes (Normal, Middle, Advanced) and supports on-chip debug via JTAG interface. Its system architecture integrates a Bus Controller (BSC), Clock Pulse Generator (CPG), and Data Transfer Controller (DTC) for efficient memory-mapped I/O and DMA transfers without CPU intervention.
Peripheral integration includes eight 16-bit Timer Pulse Units (TPU) with PWM and input capture, four asynchronous serial interfaces (SCI), one I²C bus interface, and a watchdog timer (WDT) with windowed timeout capability. All peripherals are memory-mapped into the 4 GB linear address space and accessible via dedicated SFRs with bit-field control.

FAQ
What is the maximum operating frequency of the R5F61664MN50FPV?
The R5F61664MN50FPV supports a maximum CPU clock frequency of 50 MHz, achieved via internal PLL multiplication of an external crystal or clock source. This frequency is fully supported across the specified operating voltage range (3.0–3.6 V) and temperature range (−40°C to +85°C). The R5F61664MN50FPV datasheet confirms timing compliance for all internal buses and peripherals at this rate, including TPU counter operation and SCI baud generation.
Does the R5F61664MN50FPV include on-chip debug capability?
Yes, the R5F61664MN50FPV integrates a full IEEE 1149.1 JTAG interface (pins 90–93) supporting boundary-scan testing, flash programming, and real-time debugging with Renesas E1/E20 emulators. This interface enables non-intrusive breakpoint setting, register inspection, and memory access without halting peripheral operation-critical for validating timing-critical firmware on the R5F61664MN50FPV.
What is the Flash memory endurance specification for the R5F61664MN50FPV?
The R5F61664MN50FPV specifies 10,000 write/erase cycles for its 512 KB on-chip Flash memory, validated under standard industrial conditions (3.3 V, 25°C). This endurance rating applies to each sector independently and supports field firmware updates with wear-leveling implemented in application software. The R5F61664MN50FPV does not include auto-wear-leveling hardware; design must manage sector usage to meet lifetime requirements.
Is the R5F61664MN50FPV pin-compatible with other H8SX/1664M Group devices?
Yes, the R5F61664MN50FPV shares identical pinout and electrical characteristics with all LQFP-100 variants in the H8SX/1664M Group, including R5F61664MFPV (same package, different speed grade) and R5F61668MFPV (same package, higher Flash and speed). Pin-to-pin compatibility extends to power, ground, reset, clock, JTAG, and all peripheral I/O assignments-enabling drop-in replacement within the same package family without PCB modification.
What peripheral interfaces are integrated into the R5F61664MN50FPV?
The R5F61664MN50FPV integrates eight 16-bit Timer Pulse Units (TPU), four Serial Communications Interfaces (SCI), one I²C bus interface, a watchdog timer (WDT) with windowing, and a Data Transfer Controller (DTC). It also includes a Bus Controller (BSC), Clock Pulse Generator (CPG), and Interrupt Controller (INTC).
