Product details
Overview
R7F7010493AFP-C#KA4 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring 2 MB flash, 256 KB RAM, and dual-lockstep CPU cores for ASIL-D functional safety compliance. It integrates CAN FD (up to 5 channels), Ethernet AVB, LIN, and hardware security module (ICUMD) for secure boot and cryptographic acceleration. Designed for powertrain and chassis control units requiring high-integrity real-time execution.
For engineers reviewing the R7F7010493AFP-C#KA4 datasheet, R7F7010493AFP-C#KA4 pinout, R7F7010493AFP-C#KA4 application, or R7F7010493AFP-C#KA4 equivalent, key selection criteria include ASIL-D certification evidence, dual-core lockstep timing behavior, flash ECC coverage depth, ICUMD cryptographic algorithm support (AES-128/256, SHA-256, RSA-2048), and CAN FD data-rate capability up to 5 Mbps.
Technical Context
The R7F7010493AFP-C#KA4 implements a dual-core RH850 G3KH CPU with hardware-enforced lockstep operation, where one core executes instructions while the other verifies results cycle-by-cycle. It includes integrated memory protection units (MPU), error-correcting code (ECC) on both flash and SRAM, and a dedicated safety monitor (SFM) that independently validates CPU and memory subsystem health.
Its peripheral set is architected for automotive domain controllers: five CAN FD controllers with time-triggered communication support, a 100BASE-T1 Ethernet MAC with AVB timestamping, and an intelligent cryptographic unit (ICUMD) with dedicated DMA and side-channel resistant execution for secure boot, key provisioning, and OTA update authentication.

Pinout & Package
Package: 176-pin LQFP (24 mm × 24 mm, 0.5 mm pitch), moisture sensitivity level (MSL) 3, RoHS-compliant, automotive-grade (AEC-Q100 Grade 1, −40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_1P2 | Digital core supply (1.2 V) | Must be decoupled with ≥10 µF ceramic + 100 nF near pin; voltage tolerance ±3% for lockstep stability. |
| VDD_3P3 | I/O and peripheral supply (3.3 V) | Supplies CAN transceivers, Ethernet PHY interface, and GPIO; requires separate regulation from VDD_1P2. |
| RESETn | Active-low reset input | Asynchronous, level-sensitive; must be held low ≥100 µs after VDD_1P2 and VDD_3P3 stabilize to guarantee safe initialization. |
| CLKIN | External crystal oscillator input | Accepts 8–20 MHz fundamental-mode crystal; feeds PLL for 240 MHz core clock generation with jitter <1 ps RMS. |
| ETH_MDIO / ETH_MDC | Ethernet management interface | IEEE 802.3-compliant MDIO/MDC pair for PHY register access; operates at ≤2.5 MHz with 3.3 V tolerant I/O. |
| CANFD0_TX / CANFD0_RX | Channel 0 CAN FD transceiver interface | Differential pair routed as controlled-impedance (120 Ω) trace; requires external CAN transceiver (e.g., TJA1044T). |
Key Features
| Feature | Design Value |
|---|---|
| Dual-core lockstep monitoring | Hardware-synchronized comparison of instruction execution and data paths; detects transient faults within ≤10 ns latency. |
| Flash ECC with background correction | Corrects single-bit errors during normal program execution without CPU stall; logs uncorrectable multi-bit errors to safety status register. |
| ICUMD secure boot enforcement | Verifies signature of boot image using embedded public key; blocks execution if hash mismatch or certificate chain invalidation occurs. |
| Time-triggered CAN FD scheduling | Hardware-based transmission scheduling with guaranteed jitter <50 ns; supports synchronized frame transmission across all 5 CAN FD channels. |
| Integrated Ethernet AVB stack offload | Hardware timestamping and traffic shaping logic reduces CPU load by ~35% vs. software-only AVB implementation. |

FAQ
What is the maximum operating temperature range certified for R7F7010493AFP-C#KA4?
The R7F7010493AFP-C#KA4 is qualified per AEC-Q100 Grade 1, with a certified operating junction temperature range of −40°C to +125°C. This rating is validated through accelerated stress testing including HTOL (High Temperature Operating Life) and TC (Temperature Cycling), ensuring reliability in under-hood automotive environments where ambient temperatures may reach 105°C.
Does R7F7010493AFP-C#KA4 support JTAG debugging in production mode?
Yes, R7F7010493AFP-C#KA4 retains full JTAG debug capability via pins JP0_TCK, JP0_TDI, JP0_TDO, and JP0_TMS even in secured production mode. However, debug access requires valid authentication keys programmed into the ICUMD fuse bank; unauthorized attempts trigger permanent debug lock and erase of sensitive registers.
How is functional safety compliance documented for R7F7010493AFP-C#KA4?
R7F7010493AFP-C#KA4 is supported by a complete ISO 26262:2018 ASIL-D safety package, including FMEDA reports, safety manual (R01UH0622EJxxxx), hardware safety analysis summary, and diagnostic software library (Renesas Safety Package v3.2). All documentation is publicly accessible via Renesas' Automotive Safety Hub with customer registration.
What Ethernet standards does R7F7010493AFP-C#KA4 natively support?
R7F7010493AFP-C#KA4 integrates a 100BASE-T1 Ethernet MAC with native support for IEEE 802.1Qav (AVB) stream reservation, IEEE 802.1Qbv (time-aware shaper), and IEEE 1722 (AVB transport protocol). It does not include a PHY; external 100BASE-T1 PHY (e.g., Marvell 88Q2112) must be used with MII/RMII interface routing.
Can R7F7010493AFP-C#KA4 execute secure over-the-air (OTA) updates?
Yes, R7F7010493AFP-C#KA4 supports secure OTA updates via its ICUMD cryptographic engine. The device verifies digital signatures (ECDSA P-256) and decrypts payloads (AES-256-GCM) in hardware before writing to flash. Secure boot ensures only authenticated firmware images are executed, preventing rollback or tampering during update deployment.
