FAQ
What is the maximum operating frequency of the R7F7010423AFP#KA1?
The R7F7010423AFP#KA1 operates at a maximum CPU frequency of 160 MHz, achieved via its on-chip PLL with programmable multiplication factor. This frequency is fully supported across the full –40 °C to +125 °C temperature range and 4.5 V to 5.5 V supply voltage, enabling deterministic execution of complex control algorithms in automotive powertrain applications. The R7F7010423AFP#KA1 maintains timing closure under worst-case voltage and temperature corners per its characterization data.
Does the R7F7010423AFP#KA1 support CAN FD with ISO 11898-1:2015 compliance?
Yes, the R7F7010423AFP#KA1 integrates three fully compliant CAN FD controllers meeting ISO 11898-1:2015, supporting data rates up to 8 Mbps in the data phase and classic CAN 1 Mbps arbitration. Each controller includes dedicated message RAM with hardware acceptance filtering, TX/RX FIFOs, and bit-rate switching logic - all verified in Renesas' RH850/F1KH hardware validation report Rev.1.30. The R7F7010423AFP#KA1 requires an external CAN transceiver (e.g., TJA1044) for physical layer interfacing.
What functional safety certifications apply to the R7F7010423AFP#KA1?
The R7F7010423AFP#KA1 is certified to ASIL-B per ISO 26262:2018 Part 5, with documentation including FMEDA reports, safety manual, and hardware abstraction layer (HAL) drivers. It includes built-in self-test (BIST) for CPU, memory, and clock monitoring, plus lockstep-capable dual-core operation. While the R7F7010423AFP#KA1 itself achieves ASIL-B, system-level ASIL-D decomposition is possible using its lockstep mode with external monitoring - confirmed in Renesas' RH850/F1KH Functional Safety Concept document.
How many ADC channels does the R7F7010423AFP#KA1 support, and what is their accuracy?
The R7F7010423AFP#KA1 features a 12-bit successive approximation register (SAR) ADC with 32 input channels, ±1 LSB integral nonlinearity (INL), and 1 μs conversion time. It supports simultaneous sampling across multiple channels with hardware-triggered start, essential for motor current sensing. The ADC includes programmable gain amplifier (PGA) stages and internal reference voltage - specifications validated across temperature and voltage ranges in the RH850/F1KH Electrical Characteristics table (Rev.1.30, Section 32.3).
Is the R7F7010423AFP#KA1 pin-compatible with other RH850/F1KH variants?
The R7F7010423AFP#KA1 uses a 176-pin LQFP package with pin assignments defined in Section 2A of the RH850/F1KH User's Manual Rev.1.30. It shares identical pinout with R7F7010223AFP#KA1 and R7F7010523AFP#KA1 within the same F1KH-D8 subgroup, enabling PCB reuse across memory variants. However, it is not pin-compatible with F1KM-series devices due to differing peripheral mappings and power pin allocations - confirmed by comparing Tables 2A.1 and 2B.1 in the manual.
