Product details
Overview
R7F7016863AFP-C#KA1 from Renesas Electronics is a 32-bit RH850/F1K automotive microcontroller featuring a dual-core lockstep CPU, 4 MB on-chip flash memory, 512 KB RAM, and integrated CAN FD, LIN, and SENT interfaces. It operates at up to 160 MHz, supports ASIL-D functional safety per ISO 26262, and targets engine control units (ECUs) requiring high-integrity real-time processing.
For engineers reviewing the R7F7016863AFP-C#KA1 datasheet, R7F7016863AFP-C#KA1 pinout, R7F7016863AFP-C#KA1 application, or R7F7016863AFP-C#KA1 equivalent, key selection criteria include dual-core lockstep execution, ASIL-D certification evidence, CAN FD bandwidth (5 Mbps), flash ECC protection, and 160 MHz real-time interrupt latency under safety monitor supervision.
Technical Context
The R7F7016863AFP-C#KA1 implements two synchronized RH850G3K cores executing identical instructions with cycle-accurate comparison; mismatch triggers a safety interrupt and system reset. Its memory subsystem includes 4 MB flash with single-bit error correction and double-bit error detection (SEC-DED), plus 512 KB SRAM with parity checking and lockstep shadow RAM for safety-critical data.
Peripheral integration includes three CAN FD controllers (ISO 11898-1:2015 compliant), four LIN v2.2 controllers, eight SENT receivers, and a 12-bit ADC with 48 channels and hardware scan sequencing - all accessible via dedicated safety monitors and configurable error injection test modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon AURIX TC397XP | Tri-core architecture (2x TriCore + 1x Cortex-M7); 8 MB flash; no native SENT support | Targets higher-complexity ADAS domains; requires external SENT decoder IC | Select when needing >4 MB flash or Cortex-M7 co-processing; verify SENT interface compatibility |
| NXP S32K344 | Single Arm Cortex-M7 core with lockstep option; 4 MB flash; integrated SENT; ASIL-D certified | Lower gate count and power; optimized for mid-tier ECUs with reduced peripheral count | Select for cost-sensitive ASIL-D applications where dual RH850 cores are not required |
Compared with R7F7016863AFP-C#KA1, the TC397XP offers greater flash capacity but lacks native SENT, while the S32K344 provides comparable ASIL-D capability in a smaller footprint but with single-core lockstep - making R7F7016863AFP-C#KA1 optimal for legacy RH850 ecosystem migration and high-channel SENT sensor integration.

FAQ
What safety certifications does the R7F7016863AFP-C#KA1 support?
The R7F7016863AFP-C#KA1 is designed to meet ISO 26262 ASIL-D requirements. It includes dual-core lockstep CPU, memory SEC-DED ECC, safety monitor IP, and built-in self-test (BIST) features. Renesas provides safety manuals, FMEDA reports, and hardware abstraction layers to support customer certification efforts - though final ASIL-D validation remains the responsibility of the end-system integrator using R7F7016863AFP-C#KA1.
Does the R7F7016863AFP-C#KA1 support CAN FD at full 5 Mbps?
Yes, the R7F7016863AFP-C#KA1 supports CAN FD with bit rates up to 5 Mbps on all three integrated CAN FD controllers. Each channel complies with ISO 11898-1:2015 and supports flexible data phase lengths, CRC polynomial selection, and automatic retransmission - enabling high-bandwidth diagnostics and real-time control messaging in modern vehicle networks using R7F7016863AFP-C#KA1.
What is the purpose of the VDDSAF and VSSSAF pins on the R7F7016863AFP-C#KA1?
The VDDSAF and VSSSAF pins provide an isolated power and ground domain exclusively for the R7F7016863AFP-C#KA1's safety monitor, lockstep comparison logic, and error reporting circuitry. This separation prevents fault propagation from the main power domain and ensures independent operation of safety-critical functions - a mandatory requirement for ASIL-D compliance when using R7F7016863AFP-C#KA1 in automotive safety systems.
Can the R7F7016863AFP-C#KA1 execute user code from RAM?
Yes, the R7F7016863AFP-C#KA1 supports executing code from its 512 KB on-chip SRAM, including lockstep shadow RAM. This capability enables secure over-the-air (OTA) firmware updates and runtime algorithm loading. However, execution from RAM bypasses flash ECC protection, so critical safety routines must remain in flash - a design constraint explicitly documented in the R7F7016863AFP-C#KA1 hardware manual.
How many SENT receivers does the R7F7016863AFP-C#KA1 integrate?
The R7F7016863AFP-C#KA1 integrates eight hardware SENT receivers, each supporting standard SENT frame formats (single/dual nibble, fast/slow channel) and configurable time quantum. These operate independently of the CPU, allowing simultaneous acquisition from multiple pressure, temperature, or position sensors - a key feature distinguishing R7F7016863AFP-C#KA1 from non-SENT-capable RH850 variants.
