Renesas R7F7016233AFP-C#KA3

Overview

R7F7016233AFP-C#KA3 from Renesas Electronics is a 32-bit RH850/F1K automotive microcontroller with 3MB on-chip flash memory, 384KB RAM, and dual-lockstep CPU core for ASIL-D functional safety compliance. It integrates CAN FD (up to 5 channels), LIN, Ethernet AVB, and hardware security module (HSM) supporting AES-128/256, SHA-256, and RSA-2048. Used in automotive ADAS domain controllers requiring real-time deterministic execution and ISO 26262-compliant safety mechanisms.

For engineers reviewing the R7F7016233AFP-C#KA3 datasheet, R7F7016233AFP-C#KA3 pinout, R7F7016233AFP-C#KA3 application, or R7F7016233AFP-C#KA3 equivalent, key selection criteria include ASIL-D certification status, dual-core lockstep configuration, CAN FD channel count, flash ECC coverage, and HSM cryptographic acceleration support.

Technical Context

The R7F7016233AFP-C#KA3 implements a dual-core RH850 G3KH CPU executing in lockstep mode with automatic fault detection and error signaling via dedicated safety monitor. Its memory subsystem includes 3MB of flash with 100% single-bit error correction and double-bit error detection (SECDED), plus 384KB of SRAM with parity protection and ECC-enabled access paths.

Peripherals are safety-managed through redundant clock domains, independent watchdog timers (WDT and SWDT), and memory protection units (MPU) enforcing strict address space isolation between safety-critical and non-safety partitions. The integrated HSM operates as a physically isolated secure enclave with dedicated bus interface and tamper-resistant key storage.
