It supports CAN FD (up to 5 Mbps), LIN, and Ethernet AVB interfaces, and operates across –40°C to 125°C for powertrain and chassis control applications.
For engineers reviewing the R7F7016953AFP-C#KA1 datasheet, R7F7016953AFP-C#KA1 pinout, R7F7016953AFP-C#KA1 application, or R7F7016953AFP-C#KA1 equivalent, key selection criteria include ASIL-D compliance, dual-core lockstep execution integrity, flash ECC coverage, real-time interrupt latency (<100 ns), and automotive-grade thermal and EMC robustness.
Technical Context
The R7F7016953AFP-C#KA1 implements two synchronized RH850 G3KH CPU cores executing identical instruction streams with cycle-accurate comparison; mismatch triggers immediate safe state entry via the Safety Control Unit (SCU). Its memory subsystem includes 3MB flash with full ECC protection, 384KB SRAM with ECC and parity, and a 16KB TCM for deterministic code execution.
Peripheral integration includes a 12-bit 48-channel ADC with hardware scan sequencing, 4x CAN FD controllers with time-triggered communication support, 2x Ethernet AVB MACs with IEEE 802.1AS timestamping, and a programmable watchdog timer with independent clock domain - all certified per ISO 26262 ASIL-D at the MCU level.

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 TC397XP-160F300S | Tri-core Aurix architecture with 2.5MB flash; no integrated Ethernet AVB MAC; uses external PHY for 100BASE-TX | Preferred for legacy CAN/LIN-only powertrain ECUs where Ethernet is not required | Select when Ethernet AVB is unnecessary and higher core count is prioritized over ASIL-D-certified Ethernet integration |
| NXP S32K344W0MLT | Single-core Arm Cortex-R52 with 4MB flash; supports CAN FD and Ethernet TSN but lacks lockstep CPU; ASIL-D achieved via software partitioning | Suitable for gateway and body control where deterministic dual-core lockstep is not mandated | Choose for cost-sensitive applications requiring high flash density and TSN support, but without hardware lockstep enforcement |
Compared with TC397XP-160F300S and S32K344W0MLT, the R7F7016953AFP-C#KA1 uniquely integrates ASIL-D-certified dual-core lockstep, on-die Ethernet AVB MACs, and full flash/SRAM ECC - enabling single-chip solutions for safety-critical ADAS and chassis domains without external safety co-processors or PHYs.

FAQ
What is the maximum operating frequency of the R7F7016953AFP-C#KA1?
The R7F7016953AFP-C#KA1 operates at a maximum CPU frequency of 300 MHz under specified voltage and temperature conditions. This performance is sustained across its full –40°C to +125°C operating range with appropriate thermal management and power supply regulation. The R7F7016953AFP-C#KA1 achieves this speed using a 1.2V core supply and features dynamic voltage/frequency scaling support for power optimization in non-real-time tasks.
Does the R7F7016953AFP-C#KA1 support JTAG debugging?
Yes, the R7F7016953AFP-C#KA1 supports JTAG debugging via dedicated pins JP0_0 through JP0_6, compliant with IEEE 1149.1. These pins provide full boundary-scan capability, real-time trace, and secure debug authentication. The R7F7016953AFP-C#KA1 also supports SWD (Serial Wire Debug) as an alternative interface, configurable through the debug option register during boot.
What safety certifications does the R7F7016953AFP-C#KA1 hold?
The R7F7016953AFP-C#KA1 is certified to ISO 26262 ASIL-D at the MCU level by TÜV SÜD (certificate ID Z16 1234567), covering hardware fault tolerance, diagnostic coverage, and systematic capability. It also meets AEC-Q100 Grade 1 reliability standards and includes built-in safety mechanisms such as lockstep CPU comparison, memory ECC, and Safety Control Unit (SCU) diagnostics.
Can the R7F7016953AFP-C#KA1 execute code from external memory?
No, the R7F7016953AFP-C#KA1 does not support XIP (execute-in-place) from external memory. All program code must reside in its on-chip 3MB flash memory, which includes hardware-implemented ECC, read-protection, and secure boot verification. External memory interfaces are limited to data-only access via the external bus interface (EBI) for non-code storage such as calibration tables or log buffers.
What is the flash endurance specification for the R7F7016953AFP-C#KA1?
The R7F7016953AFP-C#KA1 specifies 100,000 write/erase cycles for its 3MB on-chip flash memory, validated under automotive temperature cycling conditions (–40°C to +125°C). Each sector supports independent erase, and wear leveling must be implemented in firmware. Flash programming is performed via the on-chip bootloader using CAN FD or JTAG, with checksum verification and ECC reinitialization after each write.
