This MCU targets real-time domain control units in advanced driver assistance systems (ADAS) and vehicle gateway modules.
For engineers reviewing the R7F701462EAFB-C#KA0 datasheet, R7F701462EAFB-C#KA0 pinout, R7F701462EAFB-C#KA0 application, or R7F701462EAFB-C#KA0 equivalent, key selection criteria include dual-core lockstep execution, hardware-based safety mechanisms (e.g., ECC on flash/RAM, BIST, error-correcting code), CAN FD with 5 Mbps data rate, Ethernet AVB timing accuracy (<1 µs jitter), and AEC-Q100 Grade 1 qualification for under-hood operation.
Technical Context
The R7F701462EAFB-C#KA0 implements two tightly coupled RH850 G3K CPU cores operating in lockstep mode with cycle-accurate comparison and fault detection logic. Its memory subsystem includes 2 MB of flash with 128-bit wide access, 256 KB of SRAM with ECC, and a 16 KB instruction cache with parity protection.
Peripheral integration includes a 12-channel GPTA timer with capture/compare, 12-bit ADC with 32 channels and hardware scan sequencing, 4x CAN FD controllers (ISO 11898-1:2015 compliant), 2x LINFlexD modules, and a 100BASE-T1 Ethernet MAC with AVB timestamping and traffic shaping support.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F701462EAFB-C#AA0 | Same die, but AEC-Q100 Grade 2 (−40°C to +105°C) and no Ethernet AVB support - lacks 100BASE-T1 MAC and AVB timestamping hardware. | Suitable for non-gateway ADAS modules where Ethernet connectivity is not required and ambient temperature stays below 105°C. | Select only when Ethernet AVB and extended temperature range are unnecessary; not suitable for zonal gateway or under-hood deployment. |
| TC397XP-160F300S-AC | Infineon AURIX™ TC397 with tri-core lockstep (2x TriCore + 1x PPU), 300 MHz, 8 MB flash, but no native 100BASE-T1 - requires external PHY and software AVB stack. | Higher compute throughput for complex AI inference at edge; broader toolchain support but higher BOM cost and larger footprint. | Prefer for applications demanding >200 MHz sustained performance and multi-core task partitioning beyond dual-lockstep; avoid if strict 176-pin LQFP layout or integrated AVB is mandatory. |
Compared with R7F701462EAFB-C#KA0, the R7F701462EAFB-C#AA0 omits Ethernet AVB and reduces temperature grade, while the TC397XP offers higher clock speed and memory but adds external PHY complexity and increases PCB area - making R7F701462EAFB-C#KA0 optimal for compact, safety-certified automotive gateways requiring integrated AVB.

FAQ
What is the maximum operating temperature range for R7F701462EAFB-C#KA0?
R7F701462EAFB-C#KA0 is qualified to AEC-Q100 Grade 1, supporting continuous operation from −40°C to +125°C ambient temperature. This rating covers under-hood applications such as engine control and powertrain modules where thermal stress is critical. The device includes on-die temperature sensors and thermal shutdown circuitry that triggers at 150°C junction temperature to protect against permanent damage.
Does R7F701462EAFB-C#KA0 support ISO 26262 ASIL-D certification out of the box?
R7F701462EAFB-C#KA0 provides the hardware foundation for ISO 26262 ASIL-D compliance, including dual-core lockstep CPU, ECC on flash and RAM, built-in BIST, and safety monitor peripherals. However, full ASIL-D certification requires system-level validation, safety software integration (e.g., SafeTI™ or Renesas FSP safety packages), and FMEDA analysis - R7F701462EAFB-C#KA0 itself is ASIL-D ready but not pre-certified as a standalone component.
How many CAN FD channels does R7F701462EAFB-C#KA0 integrate, and what is the maximum data rate?
R7F701462EAFB-C#KA0 integrates four independent CAN FD controllers compliant with ISO 11898-1:2015. Each channel supports arbitration bit rates up to 1 Mbps and data phase bit rates up to 5 Mbps. Hardware message filtering, FIFO buffering, and loopback self-test modes are included to reduce CPU overhead and accelerate diagnostic coverage in safety-critical networks.
Is Ethernet AVB support in R7F701462EAFB-C#KA0 implemented entirely in hardware?
Yes, R7F701462EAFB-C#KA0 includes a fully hardware-accelerated 100BASE-T1 Ethernet MAC with integrated AVB functionality - including IEEE 802.1Qat (SRP), 802.1BA (AVB), and precise hardware timestamping with <1 µs jitter. No external PHY is needed beyond a standard 100BASE-T1 transformer; the MAC handles traffic shaping, stream reservation, and time-synchronized packet injection without CPU intervention.
What debug and programming interfaces are supported by R7F701462EAFB-C#KA0?
R7F701462EAFB-C#KA0 supports JTAG (IEEE 1149.1) and SWD (Serial Wire Debug) interfaces for on-chip debugging, flash programming, and boundary scan testing. It also includes a dedicated serial programming mode using UART0 with bootloader support for field firmware updates. All debug interfaces feature configurable security locking to prevent unauthorized access to flash contents or register states.
