FAQ
What is the maximum operating frequency of the R7F7017643AFP-C#KA1 CPU core?
The R7F7017643AFP-C#KA1 features a single RH850G3KH2.0 core rated for up to 240 MHz operation. This frequency is achieved using PLL0 with SSCG and supported by MainOSC (8–24 MHz) or HS IntOSC (8 MHz) inputs. The core maintains one-cycle instruction execution for basic operations, enabling deterministic real-time response in automotive control loops.
Does the R7F7017643AFP-C#KA1 support CAN-FD communication?
Yes, the R7F7017643AFP-C#KA1 integrates 8 channels of RS-CANFD interface compliant with ISO 11898-1:2015. Each channel supports data rates up to 5 Mbps, FD frame formats, and hardware CRC calculation. The peripheral includes dedicated message RAM, filtering, and error counters - eliminating need for external CAN-FD transceivers in most implementations.
What safety certifications apply to the R7F7017643AFP-C#KA1?
The R7F7017643AFP-C#KA1 is developed as a Safety Element out of Context (SEooC) per ISO 26262:2018 Part 3. It includes hardware safety mechanisms such as ECC on Code Flash, Data Flash, Local RAM, Retention RAM, Global RAM, CSIH, RS-CANFD, and FLXA; clock monitors (CLMA); and voltage supervisors (LVI, CVM). These features support ASIL-B system integration with documented FMEDA data available from Renesas.
How does the Low Power Sampler (LPS) function on the R7F7017643AFP-C#KA1?
The LPS in R7F7017643AFP-C#KA1 operates independently of the CPU core to poll up to 32 GPIOs or ADC channels at programmable intervals. It triggers interrupts only upon state change or threshold crossing, reducing average current consumption to sub-μA levels during deep sleep modes like DeepSTOP. This enables always-on functionality in battery-powered modules without compromising runtime.
Is the R7F7017643AFP-C#KA1 pin-compatible with other RH850/F1KM-S2 variants in 176-pin LQFP?
Yes, all RH850/F1KM-S2 176-pin LQFP variants - including R7F7016483AFP-C, R7F7016493AFP-C, and R7F7017643AFP-C#KA1 - share identical mechanical pinout and power/ground assignments. However, peripheral enablement (e.g., PWM-Diag count, ADC channels, serial interface count) varies by part number and must be validated against the specific device's register map and initialization code.
