FAQ

What is the maximum clock frequency supported by the R5F64175DFD#UB?

The R5F64175DFD#UB supports a maximum CPU clock frequency of 64 MHz, achieved via its on-chip PLL frequency synthesizer with main clock oscillator input. At this frequency, the device achieves a minimum instruction execution time of 15.625 ns, enabling hard real-time response in motor control and automotive communication tasks. The datasheet confirms this rating applies to the D-version (-40°C to +85°C) under VCC = 3.0 to 5.5 V.

Does the R5F64175DFD#UB include an integrated CAN transceiver?

No, the R5F64175DFD#UB integrates only the CAN protocol controller (ISO 11898-1 compliant with 32 mailboxes), not the physical layer transceiver. It requires an external CAN transceiver such as the TJA1050 or SN65HVD230 connected to P8_2 (CAN0OUT) and P8_3 (CAN0IN). The MCU provides CAN wake-up capability via the CAN0WU signal on P8_3.

How many analog-to-digital converter channels does the R5F64175DFD#UB support?

The R5F64175DFD#UB supports 34 channels of 10-bit analog-to-digital conversion, as confirmed in Table 1.1 for the 144-pin package. These include AN_0 to AN_7 (P10_0–P10_7), AN0_0 to AN0_7 (P0_0–P0_7), AN2_0 to AN2_7 (P2_0–P2_7), and AN15_0 to AN15_7 (P15_0–P15_7). All channels integrate sample-and-hold functionality for accurate acquisition of fast-changing signals.

Is the R5F64175DFD#UB pin-compatible with other R32C/117 Group devices?

Yes, the R5F64175DFD#UB shares identical pinout and electrical characteristics with all other 144-pin LQFP variants in the R32C/117 Group (e.g., R5F64176DFD#UB, R5F64177DFD#UB), including identical function mapping for CAN, UART, A/D, and timer peripherals. This allows direct substitution within the same package footprint when upgrading flash/RAM capacity or operating frequency.

What debug interface does the R5F64175DFD#UB support?

The R5F64175DFD#UB supports on-chip debug via the standard JTAG interface, as documented in Section 1.3 of the datasheet. It enables full boundary-scan testing, real-time trace, flash programming, and breakpoint-based debugging without requiring external emulators. The debug circuitry is integrated into the R32C/100 Series CPU core and operates across the full −40°C to +85°C temperature range.
