Product details
Overview
R7F7010464AFP-C#AA4 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring 2 MB flash memory, 256 KB RAM, and dual-core lockstep CPU architecture for ASIL-D functional safety compliance. It integrates CAN FD, LIN, FlexRay, and Ethernet AVB interfaces, and operates at up to 160 MHz with hardware-based ECC on both flash and SRAM. It is deployed in engine control units (ECUs) requiring real-time deterministic execution and ISO 26262-certified safety mechanisms.
For engineers reviewing the R7F7010464AFP-C#AA4 datasheet, R7F7010464AFP-C#AA4 pinout, R7F7010464AFP-C#AA4 application, or R7F7010464AFP-C#AA4 equivalent, this page delivers verified technical context, validated pin assignments, confirmed safety features, and cross-referenced alternatives aligned with automotive powertrain and chassis control design requirements.
Technical Context
The R7F7010464AFP-C#AA4 implements a dual-core RH850 G3KH CPU with lockstep monitoring and integrated Safety Support Unit (SSU) supporting hardware-assisted fault detection, memory BIST, and end-to-end data path protection. It includes a 12-bit ADC with 48 channels, 4x 32-bit timer units (GPT), and a dedicated Motor Control Timer (MFT).
Its peripheral set includes two CAN FD controllers (ISO 11898-1:2015 compliant), one FlexRay v2.1A controller with dual-channel support, and an IEEE 802.3av-compliant Ethernet AVB interface with hardware time synchronization (gPTP). All safety-critical peripherals are accessible via dedicated safety channels with independent clock domains.
Key Specifications

Pinout & Package
This device is housed in a 176-pin LQFP package (24 mm × 24 mm, 0.5 mm pitch) with exposed thermal pad, optimized for automotive under-hood thermal management and EMI resilience.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7010464AFP-C#AA1 | Same die, identical core/peripheral configuration, but qualified to AEC-Q100 Grade 2 (−40°C to +105°C) instead of Grade 1 (−40°C to +125°C). | Suitable for cabin or non-under-hood applications where ambient temperature does not exceed +105°C. | Select when thermal margin allows reduced qualification grade to lower cost; not interchangeable in under-hood ECU deployments. |
| TC377TP-64F200N-DC | Infineon AURIX™ TC3xx tri-core architecture; 200 MHz, 4 MB flash, but lacks native Ethernet AVB and uses different safety compiler toolchain. | Used in chassis control where FlexRay/CAN dominance outweighs need for Ethernet sensor aggregation. | Choose when existing AURIX toolchain investment exists or when higher flash density is prioritized over gPTP-capable Ethernet. |
Compared with R7F7010464AFP-C#AA4, the AA1 variant trades extended temperature range for cost savings in less thermally demanding zones, while the TC377 offers greater raw compute headroom but requires re-architecting Ethernet-dependent timing workflows and safety validation artifacts.

FAQ
What is the maximum junction temperature rating for R7F7010464AFP-C#AA4?
The R7F7010464AFP-C#AA4 is qualified to AEC-Q100 Grade 1 with a maximum junction temperature of +150°C. This rating is validated across its full operating voltage range (4.5 V to 5.5 V) and supports continuous operation in under-hood environments where ambient temperatures reach +125°C, provided PCB thermal design maintains θJA ≤ 28°C/W.
Does R7F7010464AFP-C#AA4 support hardware-based cryptographic acceleration?
Yes, the R7F7010464AFP-C#AA4 includes an integrated Intelligent Cryptographic Unit (ICUMD) supporting AES-128/256, SHA-256, RSA-2048, and ECC-256 with DMA-assisted operation. This enables secure boot, OTA firmware authentication, and encrypted CAN FD message payloads without consuming CPU cycles - a capability confirmed in the RH850/F1KH ICUMD User's Manual (R01UH0705EJxxxx).
What debug interface does R7F7010464AFP-C#AA4 use, and is JTAG supported?
R7F7010464AFP-C#AA4 uses the standard RH850 E1/E20 debug interface via dedicated pins (TCK, TMS, TDI, TDO, TRST_N, and TDOEN), fully compatible with Renesas E2 emulator and CS+ IDE. JTAG is supported for boundary scan and real-time trace, but SWD is not implemented - debug access requires the E1/E20 probe and RH850-specific debug firmware version 3.05 or later.
Can R7F7010464AFP-C#AA4 operate with a single 5 V supply, or are multiple rails required?
R7F7010464AFP-C#AA4 requires three independent supply domains: VDD50 (4.5–5.5 V) for I/O and core logic, VDD33 (3.0–3.6 V) for analog peripherals including ADC and comparators, and VDD15 (1.4–1.6 V) for CPU core and PLL. These must be supplied simultaneously and sequenced per the hardware manual's power-on timing diagram - no single-rail operation is supported.
Is Ethernet AVB support in R7F7010464AFP-C#AA4 limited to 100BASE-T1, or does it include 1000BASE-T capability?
R7F7010464AFP-C#AA4 supports only IEEE 802.3av 100BASE-T1 (single-pair automotive Ethernet) with integrated gPTP timestamping and traffic shaping. It does not implement 1000BASE-T PHY logic or MAC extensions - 1000BASE-T requires external PHY and is outside the scope of the on-chip Ethernet controller as defined in the RH850/F1KH Hardware User's Manual Rev.1.30.
