It operates at up to 32 MHz, supports 1.6–5.5 V supply, and includes 12-bit ADC (24 channels), 16-bit timer arrays, and low-power SNOOZE mode. It targets automotive body electronics and industrial control nodes requiring robust serial communication.
For engineers reviewing the R5F10DMEJFB#V2 datasheet, R5F10DMEJFB#V2 pinout, R5F10DMEJFB#V2 application, or R5F10DMEJFB#V2 equivalent, key selection criteria include CAN channel count, flash endurance (100k write/erase cycles), operating temperature range (−40°C to +105°C), and compliance with AEC-Q100 Grade 2 for automotive use.
Technical Context
The R5F10DMEJFB#V2 implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions and a 3-stage pipeline. It integrates a single CAN 2.0B controller with message objects, FIFO buffer, and automatic retransmission-configured via dedicated CAN registers (CAN0CTL, CAN0MBS).
Its memory subsystem includes on-chip 128 KB flash (with block erase and page programming), 4 KB data flash (for EEPROM emulation), and 8 KB SRAM. Power management features include HALT, STOP, and SNOOZE modes, with wake-up from CAN interrupt or external pin in ≤3.5 µs.

FAQ
What is the maximum operating frequency of the R5F10DMEJFB#V2?
The R5F10DMEJFB#V2 operates at a maximum clock frequency of 32 MHz. This speed is achieved using the on-chip high-speed oscillator or an external crystal/resonator. At 32 MHz, the RL78 core executes instructions with predictable timing, enabling deterministic CAN frame handling and real-time response to interrupts. The R5F10DMEJFB#V2 maintains full functionality-including ADC sampling and timer capture-across its entire 1.6–5.5 V supply range at this frequency.
Does the R5F10DMEJFB#V2 support AEC-Q100 qualification?
Yes, the R5F10DMEJFB#V2 is qualified to AEC-Q100 Grade 2, covering operation from −40°C to +105°C. This qualification confirms its suitability for automotive body electronics applications such as door modules, seat controllers, and lighting units. The R5F10DMEJFB#V2 undergoes stress testing including HTOL, TC, and ESD per AEC-Q100 Rev G, and its qualification status is documented in Renesas' official reliability reports-not inferred from family-level data.
How many CAN interfaces does the R5F10DMEJFB#V2 include?
The R5F10DMEJFB#V2 includes one fully compliant CAN 2.0B controller (CAN0), with dedicated TX/RX pins (P20/P21), 32 message objects, hardware FIFO, and automatic retransmission. It supports both standard and extended identifiers and operates at bit rates up to 1 Mbps. No second CAN channel is present-this distinguishes it from the pin-compatible R5F10DMFJFB#V2, which adds CAN1. The R5F10DMEJFB#V2's single CAN interface is sufficient for most body-control network nodes.
What type of nonvolatile memory is available on the R5F10DMEJFB#V2?
The R5F10DMEJFB#V2 integrates 128 KB of on-chip flash memory for program code and 4 KB of dedicated data flash for parameter storage. The data flash supports 100,000 write/erase cycles and is managed via Renesas' Flash Self-Programming (FSP) library. Unlike general flash, this 4 KB region is optimized for frequent updates-enabling EEPROM-like usage for calibration data, device configuration, or event logs without external memory. The R5F10DMEJFB#V2 does not include true EEPROM or FRAM.
Is the R5F10DMEJFB#V2 pin-compatible with other RL78/D1A 80-pin variants?
Yes, the R5F10DMEJFB#V2 shares the same 80-pin LQFP package and pinout with all RL78/D1A 80-pin CAN variants-including R5F10DMDJFB#V2, R5F10DMFJFB#V2, R5F10DMGJFB#V2, and R5F10DMJJFB#V2. Pin functions for power, reset, clocks, CAN0TX/CAN0RX, and all port I/O are identical across these parts. Differences lie in internal resources (e.g., flash size, RAM, CAN channel count), not pin assignment-allowing drop-in replacement within the same variant group when design margins permit.
