FAQ
What is the maximum operating temperature range for the R7F7017623AFP-C#KA1?
The R7F7017623AFP-C#KA1 is qualified for operation from –40°C to +105°C ambient temperature, meeting AEC-Q100 Grade 2 requirements. This range supports deployment in engine bay-proximate body control modules and interior modules exposed to cabin temperature extremes. The device includes on-die thermal monitoring via Core Voltage Monitors (CVM) and Low-Voltage Indicator (LVI) to trigger safe shutdown if limits are exceeded. R7F7017623AFP-C#KA1 maintains full specification compliance across this range without derating.
Does the R7F7017623AFP-C#KA1 support CAN-FD, and how many channels are available?
Yes, the R7F7017623AFP-C#KA1 integrates 8 independent RS-CANFD channels compliant with ISO 11898-1:2015, supporting data rates up to 5 Mbps and payloads up to 64 bytes. Each channel features programmable bit timing, hardware message filtering, FIFO buffering, and error counters. These channels are fully supported in the RH850/F1KM-S2 peripheral set and validated in Renesas' R01DS0442EJ0100 datasheet Section 1B.2. R7F7017623AFP-C#KA1 does not support Classic CAN-only mode; CAN-FD is the native protocol.
Is the R7F7017623AFP-C#KA1 pin-compatible with other RH850/F1KM-S2 variants in 144-pin LQFP?
Yes, the R7F7017623AFP-C#KA1 shares identical pinout, electrical characteristics, and mechanical dimensions with all other 144-pin LQFP RH850/F1KM-S2 devices including R7F7016463AFP-C and R7F7016473AFP-C. Pin assignments for power, reset, clocks, JTAG, CAN, LIN, ADC, and GPIO are functionally consistent across the family. However, peripheral enablement (e.g., ETNB, MEMC) and flash/RAM size differ - firmware and safety configuration must be validated per part number. R7F7017623AFP-C#KA1 requires no PCB redesign when substituting within the same package variant.
What debug and trace capabilities does the R7F7017623AFP-C#KA1 provide?
The R7F7017623AFP-C#KA1 supports on-chip debug (OCD) via JTAG and boundary scan (IEEE 1149.1), enabling full visibility into CPU state, memory, and peripheral registers during development. It lacks trace RAM (not supported in 2 MB flash variants per R01DS0442EJ0100 Section 1B.4), so real-time instruction trace is unavailable. Debug features include hardware breakpoints, watchpoints, and secure debug authentication via ICUMD. For production diagnostics, R7F7017623AFP-C#KA1 provides RESETOUT signaling and FOUT clock output for external test equipment synchronization.
How does the R7F7017623AFP-C#KA1 implement functional safety per ISO 26262?
The R7F7017623AFP-C#KA1 is developed as a Safety Element out of Context (SEooC) per ISO 26262-2:2018, with documented FMEDA, safety manual, and hardware safety assessment. Key mechanisms include ECC on Code/Data Flash and all RAM types, CLMA clock monitors for PLL/MainOSC/HS IntOSC, CVM for core voltage supervision, and MPU/IPG/PEG for memory and peripheral access control. All safety features are independently verifiable and configurable via dedicated registers. R7F7017623AFP-C#KA1 achieves ASIL-B capability when integrated into a properly architected system with appropriate software safety layers.
