R7F7016523ABG-C#HC1 is qualified to AEC-Q100 Grade 1 (−40°C to +125°C), meeting automotive reliability and stress-test requirements for under-hood applications. This qualification covers the full device including CPU, memory, and all integrated peripherals. The R7F7016523ABG-C#HC1 part number explicitly denotes this Grade 1 automotive qualification in its suffix.
Does R7F7016523ABG-C#HC1 support CAN FD with ISO 11898-1:2015 compliance?
Yes, R7F7016523ABG-C#HC1 integrates four fully compliant CAN FD controllers supporting ISO 11898-1:2015, including arbitration-phase bit rates up to 1 Mbps and data-phase bit rates up to 5 Mbps. Each controller includes dedicated message RAM, filtering, and loopback test modes - all verified in Renesas' RH850/F1K Hardware User's Manual Rev.1.10.
How does the lockstep mechanism work in R7F7016523ABG-C#HC1?
R7F7016523ABG-C#HC1 employs hardware-synchronized dual RH850 G3KH cores that execute identical instructions in parallel. A dedicated comparator checks register and bus outputs every cycle; any mismatch triggers a safety interrupt and asserts the SAFETY_ERR pin. This architecture is integral to the R7F7016523ABG-C#HC1's ASIL-B certification and documented in the RH850/F1K Hardware manual Section 1.1.
What is the maximum operating frequency of R7F7016523ABG-C#HC1?
R7F7016523ABG-C#HC1 operates at a maximum CPU frequency of 120 MHz, achieved via its on-chip PLL with configurable dividers. This frequency is guaranteed across the full −40°C to +125°C temperature range and under all specified voltage conditions (VCC = 4.5 V to 5.5 V). The R7F7016523ABG-C#HC1 datasheet confirms this rating in its DC and AC characteristics tables.
Does R7F7016523ABG-C#HC1 include hardware support for SENT sensor interfaces?
Yes, R7F7016523ABG-C#HC1 includes two dedicated hardware SENT receivers compliant with SAE J2716 Rev 3.0. These modules perform pulse-width measurement, frame synchronization, and CRC validation without CPU intervention - a feature confirmed in the RH850/F1K Hardware User's Manual Section 2.11.2 and uniquely implemented in the R7F7016523ABG-C#HC1 variant.
