Product details
Overview
R7F7010333AFE#KA4 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring dual-core lockstep CPU, ASIL-B functional safety compliance, 1.5 MB on-chip flash, 192 KB SRAM, and integrated CAN FD, LIN, and SENT interfaces. It targets engine control units (ECUs), transmission control modules, and chassis domain controllers requiring high-integrity real-time processing.
For engineers reviewing the R7F7010333AFE#KA4 datasheet, R7F7010333AFE#KA4 pinout, R7F7010333AFE#KA4 application, or R7F7010333AFE#KA4 equivalent, key selection criteria include ASIL-B certification status, dual-core lockstep execution integrity, flash ECC coverage, CAN FD data rate support up to 5 Mbps, and qualified operation at 125°C ambient.
Technical Context
The R7F7010333AFE#KA4 implements a dual-core RH850G3K-H CPU with hardware-enforced lockstep comparison and error detection logic, supporting ISO 26262 ASIL-B compliance without external safety monitor. It integrates a dedicated Safety Support Core (SSC) for runtime diagnostics including memory BIST, clock monitoring, and watchdog supervision.
Peripherals include two CAN FD controllers (ISO 11898-1:2015 compliant), four LIN v2.2 controllers, six SENT receivers, and a 12-bit ADC with 32-channel multiplexing and hardware trigger synchronization - all accessible via configurable I/O ports with programmable drive strength and fail-safe pull-up/pull-down options.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Dual RH850G3K-H cores in lockstep mode; enables real-time fault detection with zero-latency comparison and automatic core isolation on mismatch. |
| Flash Memory | 1.5 MB on-chip flash with ECC protection, 128-bit wide access, and background erase capability - supports A/B swap firmware updates without interruption. |
| RAM | 192 KB SRAM with SECDED ECC, partitioned into safety-critical (64 KB) and application (128 KB) regions with MPU-based access control. |
| CAN FD Interface | 2x CAN FD controllers supporting data rates up to 5 Mbps and protocol compliance per ISO 11898-1:2015 - includes built-in bit-rate switching and flexible data length configuration. |
| Operating Temperature | -40°C to +125°C ambient; qualified per AEC-Q100 Grade 1 with extended life test validation at maximum junction temperature. |
| Safety Certification | ISO 26262 ASIL-B compliant; includes integrated Safety Support Core (SSC), memory BIST, clock domain monitors, and lockstep error reporting via dedicated interrupt vector. |

Pinout & Package
Package: 144-pin LQFP (20 mm × 20 mm, 0.5 mm pitch), moisture sensitivity level MSL3, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main power supply (3.3 V) | Supplies core logic and most peripherals; requires local 10 µF + 100 nF decoupling per power domain. |
| VDDA | Analog power supply (3.3 V) | Isolated analog rail for ADC, reference voltage, and analog comparators; must be filtered separately from digital VDD. |
| RESET | Active-low reset input | Asynchronous reset assertion resets all internal registers and state machines; held low for ≥100 µs ensures full initialization. |
| CLKIN | External crystal oscillator input | Accepts 8–20 MHz fundamental-mode crystal; internal oscillator circuit provides stable 200 MHz system clock after PLL lock. |
| CAN0_TX / CAN0_RX | CAN FD differential signal pair | Direct connection to external CAN transceiver; supports bit rates up to 5 Mbps with programmable sample point and propagation delay compensation. |
| AD00–AD31 | ADC input channels | Configurable as single-ended or differential inputs; each mapped to dedicated analog front-end with programmable gain and offset calibration registers. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-core lockstep execution | Hardware-monitored identical instruction execution across two RH850G3K-H cores with immediate fault flagging and safe state entry on divergence. |
| Integrated Safety Support Core (SSC) | Dedicated RISC-based safety monitor running independent diagnostics: memory BIST, clock frequency verification, and watchdog timer cross-check. |
| Flash with ECC and secure boot | 1.5 MB flash with single-bit error correction/double-bit error detection, plus hardware-accelerated SHA-256 and AES-128 for secure firmware authentication. |
| CAN FD with protocol offload | Two CAN FD controllers with hardware message filtering (32 filters per channel), TX/RX FIFOs, and automatic retransmission - reduces CPU load by >70% vs. software-implemented stacks. |
| SENT receiver with time-stamp capture | Six SENT receivers supporting standard (SAE J2716) and custom protocols; each captures rising/falling edge timestamps with 10 ns resolution for sensor diagnostics. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7010293AFE#KA4 | Same RH850/F1KH-D8 family but with 1 MB flash, 128 KB SRAM, and one fewer CAN FD channel. | Targeted at cost-sensitive ECUs where reduced memory and single CAN FD suffice (e.g., throttle control modules). | Select when BOM cost reduction is prioritized over future firmware scalability and multi-bus redundancy. |
| SPC5744PFK1AKLQ1 | STMicroelectronics SPC574xP series; Power Architecture e200z4 dual-core, 2 MB flash, ASIL-B certified, but no integrated SENT receivers. | Used in powertrain gateways requiring high CAN/LIN throughput but relying on external SENT interface ICs. | Choose when legacy Power Architecture toolchain compatibility or higher flash density outweighs need for on-die SENT sensor integration. |
Compared with R7F7010333AFE#KA4, the R7F7010293AFE#KA4 offers lower memory and peripheral count at reduced cost, while the SPC5744PFK1AKLQ1 provides larger flash and different architecture but requires external components for SENT functionality - making R7F7010333AFE#KA4 optimal for compact, sensor-rich ASIL-B domains.
