FAQ

What is the maximum operating frequency of the R7F7016203AFP-C#AA3?

The R7F7016203AFP-C#AA3 operates at a maximum CPU frequency of 160 MHz. This clock speed is achieved using an internal PLL with support for external crystal (1–20 MHz) or clock input. The dual-core lockstep architecture maintains timing determinism at this frequency, making R7F7016203AFP-C#AA3 suitable for hard real-time automotive control loops such as fuel injection timing and ignition spark control.

Does the R7F7016203AFP-C#AA3 support ISO 26262 functional safety certification?

Yes, the R7F7016203AFP-C#AA3 is designed to support ISO 26262 ASIL-B compliance. It includes hardware safety features such as dual-core lockstep execution, Safety Monitor (SWM), ECC on flash and SRAM, MPU with 16 regions, and fail-safe interrupt controller (FSI). These mechanisms are documented in Renesas' Functional Safety Manual for RH850/F1K, enabling systematic development of ASIL-B software on R7F7016203AFP-C#AA3 without requiring external safety co-processors.

How many CAN FD interfaces does the R7F7016203AFP-C#AA3 integrate?

The R7F7016203AFP-C#AA3 integrates two fully independent CAN FD controllers compliant with ISO 11898-1:2015. Each supports arbitration bit rates up to 1 Mbps and data bit rates up to 5 Mbps. Both controllers feature message RAM with configurable FIFOs, loopback modes for self-test, and built-in CRC and bit-stuffing logic - essential for R7F7016203AFP-C#AA3 deployment in high-bandwidth automotive networks like powertrain and chassis domains.

What type of analog-to-digital converter is included in the R7F7016203AFP-C#AA3?

The R7F7016203AFP-C#AA3 includes a 12-bit successive approximation register (SAR) ADC with 48 input channels. It supports simultaneous sampling across up to four groups, programmable conversion sequences, and hardware-triggered conversions synchronized with timer events. This ADC architecture delivers the precision and timing control required by R7F7016203AFP-C#AA3 in engine air-fuel ratio sensing, throttle position monitoring, and exhaust gas temperature measurement.

Is the R7F7016203AFP-C#AA3 pin-compatible with other RH850/F1K variants?

Yes, the R7F7016203AFP-C#AA3 is pin-compatible with other members of the RH850/F1K 176-pin LQFP family, including R7F7016204AFP-C#AA3 and R7F7016202AFP-C#AA3. All share identical mechanical footprint, power pin allocation, and primary peripheral pin assignments (CAN FD, SENT, ADC, etc.). This allows scalable memory selection - for example, upgrading from R7F7016203AFP-C#AA3 (2 MB flash) to R7F7016204AFP-C#AA3 (4 MB flash) - without PCB redesign.
