FAQ
What is the maximum operating frequency of the R5F10DMGCJFB#56G?
The R5F10DMGCJFB#56G supports a maximum CPU operating frequency of 32 MHz using its on-chip high-speed oscillator or external crystal. This frequency is achievable across the full 1.6–5.5 V supply range and −40 °C to +85 °C ambient temperature, with timing margins verified per Renesas RL78/D1A Hardware User's Manual Rev.1.20. The R5F10DMGCJFB#56G maintains instruction cycle consistency at all supported frequencies without software throttling.
Does the R5F10DMGCJFB#56G support CAN FD?
No, the R5F10DMGCJFB#56G implements two CAN 2.0B controllers compliant with ISO 11898-1:2003, supporting data rates up to 1 Mbps with standard and extended frame formats. It does not support CAN FD features such as flexible data-rate switching or increased payload size. For CAN FD capability, Renesas offers the RH850/F1K series or RA6T2 MCU family - the R5F10DMGCJFB#56G is designed specifically for legacy CAN-based automotive and industrial networks.
What debug interfaces are supported by the R5F10DMGCJFB#56G?
The R5F10DMGCJFB#56G supports Renesas E1 and E20 on-chip debug emulators via the dedicated FINE (Fast In-Circuit Emulator) interface, which uses a 6-pin SWD-compatible connector. It does not support JTAG. Debug capabilities include full breakpoint control, real-time variable watch, flash programming, and low-power mode entry/exit tracing. The R5F10DMGCJFB#56G requires no external debug circuitry beyond the standard FINE header connection.
Is the R5F10DMGCJFB#56G qualified for automotive applications?
The R5F10DMGCJFB#56G is rated for industrial temperature range (−40 °C to +85 °C) and classified as "Standard" grade per Renesas quality policy, intended for applications including industrial robots, test equipment, and office automation. While widely used in automotive body electronics, it is not AEC-Q100 qualified. For AEC-Q100 Grade 2 (−40 °C to +105 °C) automotive applications, Renesas recommends the RL78/F14 or RL78/F13 series - the R5F10DMGCJFB#56G serves best in non-safety-critical vehicle subsystems where qualification is not mandated.
What is the flash endurance specification for the R5F10DMGCJFB#56G?
The R5F10DMGCJFB#56G specifies 10,000 write/erase cycles for its 256 KB on-chip flash memory, with data retention guaranteed for 20 years at +85 °C and 100 years at +25 °C. Block erase granularity is 128 bytes, enabling fine-grained firmware updates. These values are measured per JEDEC JESD22-A117 and confirmed in Renesas RL78/D1A datasheet documentation - the R5F10DMGCJFB#56G does not support wear leveling or ECC correction in hardware.
