FAQ

What is the maximum operating frequency of the R5F10BLGCLFB#55?

The R5F10BLGCLFB#55 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 (1.6–5.5 V) and temperature range (−40°C to +105°C), with guaranteed timing margins per Renesas' AC electrical characteristics table in the R01UH0368E datasheet.

Does the R5F10BLGCLFB#55 support CAN FD?

No, the R5F10BLGCLFB#55 implements a classical CAN 2.0B controller compliant with ISO 11898-1:2003 and does not support CAN FD data rates or extended frame formats. Its CAN peripheral operates up to 1 Mbps with 32 message objects and hardware acceptance filtering - sufficient for most body electronics networks but not for high-bandwidth ADAS or powertrain applications requiring CAN FD.

Is the R5F10BLGCLFB#55 qualified for automotive use?

Yes, the R5F10BLGCLFB#55 is AEC-Q100 qualified to Grade 2 (−40°C to +105°C) and manufactured in Renesas' automotive-grade process. It meets automotive reliability standards including HTOL, ESD, and EMC requirements per ISO 11452 and CISPR 25, and is designated for "Standard" quality grade applications including door modules, seat controls, and lighting systems.

What debug interface does the R5F10BLGCLFB#55 provide?

The R5F10BLGCLFB#55 features a single-wire debug (SWD) interface compatible with Renesas' E2 and E2 Lite emulators. It supports full JTAG-like functionality - including halt/resume, register read/write, memory access, and flash programming - using only two pins (SWDIO and SWCLK), leaving all other I/Os available for application use during development and field diagnostics.

Can the R5F10BLGCLFB#55 operate from a 3.3 V supply?

Yes, the R5F10BLGCLFB#55 operates reliably from a 3.3 V supply across its full temperature range. Its I/O pins are 5 V tolerant, allowing direct connection to 5 V peripherals without level shifters, while the internal regulator maintains stable 1.8 V core voltage. The device specifies 3.3 V as a nominal operating point in its DC characteristics table with full parameter guarantees.
