FAQ

What is the maximum operating frequency of the R5F10BAGLSP#W5?

The R5F10BAGLSP#W5 supports a maximum CPU clock frequency of 32 MHz using its on-chip high-speed oscillator or external crystal. This frequency is achievable across the full operating voltage range (1.6 V to 5.5 V) and temperature range (−40 °C to +105 °C), enabling deterministic real-time execution for time-critical automotive control loops. The R5F10BAGLSP#W5 also supports sub-multiple clock division for peripheral modules to optimize power versus performance trade-offs.

Does the R5F10BAGLSP#W5 include an integrated CAN transceiver?

No, the R5F10BAGLSP#W5 integrates a CAN controller compliant with ISO 11898-1:2003 but requires an external CAN physical-layer transceiver (e.g., TJA1042 or SN65HVD230) for bus connection. Its P10 and P11 pins provide differential CAN TX and RX signals at CMOS logic levels, not bus-ready differential voltages. The R5F10BAGLSP#W5 does include a LIN physical layer driver on P12/P13, eliminating the need for an external LIN transceiver in most implementations.

Is the R5F10BAGLSP#W5 qualified for automotive applications?

Yes, the R5F10BAGLSP#W5 is AEC-Q100 Grade 2 qualified, rated for operation from −40 °C to +105 °C ambient temperature and validated for automotive body electronics applications including door modules, seat controls, and roof systems. It meets stringent requirements for thermal cycling, humidity resistance, and ESD immunity per AEC-Q100 Rev-G, and is manufactured in Renesas' IATF 16949-certified facilities. The R5F10BAGLSP#W5 is not intended for safety-critical powertrain or ADAS functions requiring ASIL certification.

What debug interface does the R5F10BAGLSP#W5 support?

The R5F10BAGLSP#W5 supports Renesas' on-chip debug interface via single-wire SWD (Serial Wire Debug), accessible through dedicated debug pins (RES# and P10/SWDIO). This enables full-speed program download, breakpoint setting, register inspection, and real-time variable monitoring without requiring external JTAG hardware. The R5F10BAGLSP#W5 debug interface is compatible with Renesas E2 Lite and E2 emulators, as well as third-party tools supporting ARM SWD protocol extensions for RL78.

How much user-accessible flash memory does the R5F10BAGLSP#W5 provide?

The R5F10BAGLSP#W5 provides 64 KB of on-chip flash memory, of which 63.5 KB is user-programmable. The remaining 0.5 KB contains factory-programmed boot code and security configuration data. Flash is organized in 1 KB blocks with individual erase capability, supports up to 100,000 write/erase cycles, and includes error correction circuitry to maintain data integrity over extended operation. The R5F10BAGLSP#W5 flash can be reprogrammed in-system via the on-chip debug interface or bootloader routines.
