Product details
Overview
R7F7016203AFP-C#BA3 from Renesas Electronics is a 32-bit RH850/F1K automotive-grade microcontroller featuring a dual-core lockstep CPU, 2 MB on-chip flash memory, 256 KB SRAM, and integrated CAN FD, LIN, and SENT interfaces. It supports ASIL-D functional safety per ISO 26262 and operates at up to 160 MHz with hardware ECC for memory protection. This MCU targets engine control units (ECUs) requiring high-integrity real-time processing.
For engineers reviewing the R7F7016203AFP-C#BA3 datasheet, R7F7016203AFP-C#BA3 pinout, R7F7016203AFP-C#BA3 application, or R7F7016203AFP-C#BA3 equivalent, key selection criteria include dual-core lockstep execution, ASIL-D compliance evidence, CAN FD timing budget, flash write endurance (100k cycles), and package thermal resistance in automotive under-hood environments.
Technical Context
The R7F7016203AFP-C#BA3 implements two synchronized RH850 G3KH CPU cores executing identical instructions with cycle-accurate comparison logic to detect divergence. It integrates a 12-bit ADC with 48 channels, 32-bit timer units (GPTA/GPTB), and a dedicated safety monitor (SFM) that independently validates core operation, memory integrity, and clock domain health.
Its peripheral set includes three CAN FD controllers supporting data rates up to 5 Mbps, one LIN controller, four SENT receivers, and a hardware security module (HSM) compliant with EVITA Medium. The device uses a 176-pin LQFP package with dedicated safety pins (e.g., SAFETY_RESET, SAFETY_CLKOUT) routed separately from functional I/O.

FAQ
What is the maximum operating junction temperature for R7F7016203AFP-C#BA3?
The R7F7016203AFP-C#BA3 is rated for a maximum junction temperature of 150°C, validated per AEC-Q100 Grade 1 qualification. This rating supports deployment in under-hood automotive environments where ambient temperatures reach 125°C and power dissipation must be managed via the exposed thermal pad and proper PCB copper pour design. Thermal derating curves are provided in the RH850/F1K Hardware User's Manual Rev.1.10.
Does R7F7016203AFP-C#BA3 support JTAG debugging in production mode?
No, R7F7016203AFP-C#BA3 disables JTAG access after secure boot completes and the debug lock bit is set. Production units use SWD (Serial Wire Debug) via the dedicated JP0 pins for post-deployment diagnostics, with authentication enforced by the integrated HSM. Full JTAG remains available only during development with unsecured flash and unlocked debug interface.
How many CAN FD channels does R7F7016203AFP-C#BA3 support, and what is their data rate capability?
The R7F7016203AFP-C#BA3 integrates three independent CAN FD controllers, each supporting nominal bit rates up to 1 Mbps and data phase bit rates up to 5 Mbps. All channels feature hardware message filtering, TX/RX FIFOs, and built-in protocol error counters-enabling concurrent communication with engine, transmission, and chassis networks without software overhead.
Is R7F7016203AFP-C#BA3 qualified to AEC-Q100, and which grade applies?
Yes, R7F7016203AFP-C#BA3 is qualified to AEC-Q100 Rev-G with Grade 1 rating (−40°C to +125°C ambient). This qualification covers stress tests including HTOL, TC, UHAST, and ESD, and is documented in Renesas' official AEC-Q100 certificate for the RH850/F1K family. The device also meets ISO 26262 ASIL-D requirements for systematic and random hardware failures.
What safety documentation is provided with R7F7016203AFP-C#BA3 for ISO 26262 compliance?
Renesas provides a complete ISO 26262 ASIL-D safety package for R7F7016203AFP-C#BA3, including Safety Manual, FMEDA report, safety analysis summary, diagnostic coverage metrics, and hardware/software interface specifications (HSI).
