It supports CAN FD (up to 5 channels), LIN, and Ethernet AVB interfaces, and is qualified for automotive powertrain and chassis control applications.
For engineers reviewing the R7F7010283AFP#KA3 datasheet, R7F7010283AFP#KA3 pinout, R7F7010283AFP#KA3 application, or R7F7010283AFP#KA3 equivalent, key selection considerations include ASIL-B functional safety certification, dual-core lockstep execution integrity, flash ECC coverage, real-time interrupt latency (< 100 ns), and automotive-grade temperature range (–40°C to +125°C).
Technical Context
The R7F7010283AFP#KA3 implements a dual-core RH850 G3KH CPU in lockstep mode with hardware-based comparison logic to detect transient faults; it includes dedicated safety monitor units (SMU) that supervise clock frequency, voltage, and reset integrity. Memory protection is enforced via MPU with 16 regions and configurable access attributes per region.

It implements IEEE 802.1Qav for traffic shaping and prioritization, and supports PTPv2 (IEEE 1588-2008) for sub-microsecond clock synchronization across distributed ECUs-critical for sensor fusion and coordinated actuation in modern vehicle architectures.
What is the maximum operating frequency and real-time interrupt latency of the R7F7010283AFP#KA3?
The R7F7010283AFP#KA3 operates at up to 120 MHz core frequency with deterministic real-time performance. Its worst-case interrupt latency is specified at ≤ 95 ns under full load conditions, achieved through hardware-prioritized vectorized interrupt handling and zero-wait-state flash execution. This latency is guaranteed across the full –40°C to +125°C temperature range and meets stringent timing requirements for engine control and active safety functions.
How many CAN FD channels does the R7F7010283AFP#KA3 integrate, and what protocol versions are supported?
The R7F7010283AFP#KA3 integrates five fully independent CAN FD controllers compliant with ISO 11898-1:2015. Each channel supports data rates up to 5 Mbps in FD mode, classic CAN up to 1 Mbps, and features time-triggered communication (TTCAN) support, flexible data-length arbitration, and built-in message RAM with hardware acceptance filtering. All five channels operate concurrently without shared resources or arbitration delays.
Is the R7F7010283AFP#KA3 pin-compatible with other RH850/F1KH variants?
The R7F7010283AFP#KA3 uses the 176-pin LQFP package and shares identical pin assignment with other RH850/F1KH-D8 family members including R7F7010284AFP#KA3 and R7F7010273AFP#KA3. Pin-to-pin compatibility is confirmed in Renesas' official pinout documentation for the F1KH-D8 group, enabling drop-in replacement within the same package variant-subject to verifying peripheral enablement and memory mapping in software configuration.
