FAQ
What is the maximum operating frequency of the R5F10DLDCJFB#12?
The R5F10DLDCJFB#12 operates at a maximum CPU clock frequency of 32 MHz, achievable using the high-speed on-chip oscillator (HOCO), an external crystal (up to 20 MHz with PLL multiplication), or an external resonator. This frequency supports real-time control loops with sub-100 μs latency and meets timing requirements for CAN FD pre-scaling and 12-bit ADC sampling at 1 MSps.
Does the R5F10DLDCJFB#12 include built-in CAN transceiver functionality?
No, the R5F10DLDCJFB#12 integrates a CAN 2.0B protocol controller but requires an external CAN transceiver (e.g., TJA1042 or SN65HVD230) for physical layer signaling. Its CAN0TX and CAN0RX pins are CMOS-level digital outputs/inputs compatible with industry-standard transceivers, and the MCU handles message filtering, buffering, and error handling in hardware.
What package type and pin count does the R5F10DLDCJFB#12 use?
The R5F10DLDCJFB#12 uses a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. This package matches the R5F10DLD and R5F10DLE variants in the RL78/D1A family and supports standard reflow soldering profiles per J-STD-020. Pin compatibility is confirmed across all 64-pin CAN-enabled D1A devices.
How much embedded flash and RAM does the R5F10DLDCJFB#12 provide?
The R5F10DLDCJFB#12 provides 128 KB of on-chip flash memory for program storage and 8 KB of SRAM for runtime data. Additionally, it includes 2 KB of data flash memory configured for EEPROM emulation with 100,000 write/erase cycles and automatic wear leveling - eliminating the need for external nonvolatile memory in most applications.
Is the R5F10DLDCJFB#12 qualified for automotive applications?
Yes, the R5F10DLDCJFB#12 is manufactured under Renesas' "High Quality" grade and qualified to AEC-Q100 Grade 2 (−40°C to +105°C). It supports functional safety features including clock frequency monitor, RAM parity checking, and BIST - making it suitable for automotive body electronics such as door modules, seat controllers, and lighting ECUs compliant with ISO 26262 ASIL-B requirements.
