FAQ
What is the maximum operating frequency of the R5F10DMDCLFB#12?
The R5F10DMDCLFB#12 supports a maximum system clock frequency of 32 MHz, achieved via its on-chip PLL operating from an external 1–20 MHz crystal or resonator. This frequency is fully supported across the full −40 °C to +85 °C temperature range and 1.8–5.5 V supply voltage, enabling deterministic real-time performance for CAN message handling and ADC sampling without derating.
Does the R5F10DMDCLFB#12 include an integrated CAN transceiver?
No, the R5F10DMDCLFB#12 integrates only the CAN protocol controller (CAN 2.0B compliant), not the physical layer transceiver. External CAN transceivers such as the RENESAS RAA100010 or TI SN65HVD23x must be used on the board to drive the CAN bus differential lines. The R5F10DMDCLFB#12 provides dedicated CAN0_TX and CAN0_RX pins (P10/P11) compatible with industry-standard transceivers.
How much data flash memory does the R5F10DMDCLFB#12 provide, and what is its endurance?
The R5F10DMDCLFB#12 includes 4 KB of on-chip data flash memory, rated for 100,000 write/erase cycles with built-in error correction code (ECC) and automatic wear leveling. This memory is electrically erasable in 128-byte blocks and is commonly used to store calibration data, device configuration, or firmware update metadata-ensuring long-term reliability in field-deployed R5F10DMDCLFB#12 applications.
What low-power modes are supported by the R5F10DMDCLFB#12?
The R5F10DMDCLFB#12 supports four low-power modes: HALT (CPU stopped, peripherals active), STOP (all clocks stopped except sub-clock for RTC), SNOOZE (CPU halted, selected peripherals like ADC and CAN remain operational), and DEEP STOP (minimal current draw with RAM retention). In SNOOZE mode, the R5F10DMDCLFB#12 achieves typical current consumption of 12 μA while maintaining CAN message reception and periodic ADC sampling.
Is the R5F10DMDCLFB#12 pin-compatible with other RL78/D1A 80-pin variants?
Yes, the R5F10DMDCLFB#12 shares identical pinout, package (LQFP80), and peripheral mapping with all other 80-pin RL78/D1A CAN variants-including R5F10DMECLFB#12, R5F10DMFCLFB#12, R5F10DMGCLFB#12, and R5F10DMJCLFB#12. This allows drop-in replacement across memory configurations without PCB redesign, provided the application firmware accommodates differences in flash/RAM size and optional features like extra timer channels.
