Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10DPFJFB#V2 | Same 100-pin LQFP package and RL78/D1A core, but with 384 KB flash and no CAN controller | Suitable for non-networked control nodes where CAN is unnecessary and flash budget is constrained | Select when CAN interface is not required and lower code density suffices |
| R5F10DMGJFB#V2 | 80-pin LQFP variant with identical 512 KB flash, 32 KB RAM, and 1-ch CAN, but fewer I/O pins (64 vs. 82) | Preferred for space-constrained designs where full 100-pin I/O count is not needed | Choose for compact layouts where reduced pin count aligns with peripheral requirements |
Compared with R5F10DPEJFB#V2, R5F10DPFJFB#V2 removes CAN capability to reduce cost and complexity in standalone control applications, while R5F10DMGJFB#V2 retains full feature parity in a smaller 80-pin footprint - enabling layout optimization without sacrificing memory or communication capability.

FAQ
What is the maximum operating frequency of the R5F10DPEJFB#V2?
The R5F10DPEJFB#V2 operates at up to 32 MHz using its on-chip high-speed oscillator or an external crystal. This frequency is fully supported across the entire 1.6–5.5 V supply range and ambient temperature range of −40°C to +105°C, ensuring deterministic real-time performance in automotive and industrial environments where the R5F10DPEJFB#V2 is deployed.
Does the R5F10DPEJFB#V2 include hardware support for functional safety standards?
Yes, the R5F10DPEJFB#V2 includes multiple hardware features aligned with ISO 26262 ASIL-B requirements: built-in self-test (BIST) for flash and RAM, clock frequency monitor (CFM), windowed watchdog timer (WDT), and parity/ECC protection on critical memory blocks. These capabilities are documented in Renesas' Functional Safety Manual for RL78/D1A and directly implemented in the R5F10DPEJFB#V2 silicon.
How many CAN channels does the R5F10DPEJFB#V2 support?
The R5F10DPEJFB#V2 supports exactly one CAN 2.0B-compliant channel, as confirmed in the RL78/D1A User's Manual Hardware Rev.1.10 Section 1.4.7 and pin function tables. This single CAN interface is routed to P10 (CAN0TX) and P11 (CAN0RX) and supports bit rates up to 1 Mbps with programmable sample points and loopback testing mode.
What is the purpose of the REGC pin on the R5F10DPEJFB#V2?
The REGC pin on the R5F10DPEJFB#V2 connects to an external 1.0 µF ceramic capacitor that stabilizes the output of the on-chip voltage regulator. This capacitor is mandatory for proper operation of the internal SMVDD domain and must be placed within 3 mm of the REGC and SMVDD0 pins per Renesas' layout guidelines in the RL78/D1A Hardware Manual Section 2.2.19.
Is the R5F10DPEJFB#V2 pin-compatible with other RL78/D1A 100-pin variants?
Yes, the R5F10DPEJFB#V2 shares identical pinout and package dimensions with other 100-pin RL78/D1A devices including R5F10DPFJFB#V2, R5F10DPGJFB#V2, and R5F10TPJJFB#V2. All use the same 100-pin LQFP footprint and maintain consistent signal assignments for power, reset, debug, and core peripherals - enabling drop-in replacement within the same family where feature sets align.
