The R7F7010183AFP#KA4 operates at a maximum CPU frequency of 120 MHz using the RH850 G3KH core. This frequency is sustained under full load with junction temperature ≤125°C and supply voltage within the specified 4.5–5.5 V range. The R7F7010183AFP#KA4 achieves this performance with hardware branch prediction and 64 KB instruction cache, enabling consistent real-time execution for automotive control tasks.
Does the R7F7010183AFP#KA4 support ISO 26262 functional safety certification?
Yes, the R7F7010183AFP#KA4 is certified to ISO 26262 ASIL-B at the device level. Its safety mechanisms - including lockstep-capable CPU, memory protection unit (MPU), safety monitor unit (SMU), and ECC-protected memories - are documented in Renesas' FMEDA report and safety manual. The R7F7010183AFP#KA4 provides the foundational hardware elements required for ASIL-B system-level compliance in engine and transmission ECUs.
What communication interfaces are integrated into the R7F7010183AFP#KA4?
The R7F7010183AFP#KA4 integrates two CAN FD controllers (supporting up to 5 Mbps), three LIN controllers, two SENT receivers/transmitters, and one FlexRay v2.1A controller. All interfaces feature hardware timestamping, message filtering, and error counters. These peripherals are directly accessible via the crossbar switch, enabling concurrent high-bandwidth communication without CPU intervention - essential for R7F7010183AFP#KA4 deployment in domain controllers.
Is the R7F7010183AFP#KA4 pin-compatible with other RH850/F1KH variants?
The R7F7010183AFP#KA4 uses a 144-pin LQFP package with a defined pinout shared across the RH850/F1KH-D8 family. It is pin-compatible with R7F7010283AFP#KA4 (2 MB flash) and R7F7010193AFP#KA4 (FlexRay instead of LIN), allowing PCB reuse across memory- or interface-variant designs. However, R7F7010183AFP#KA4 is not pin-compatible with F1KM-series devices due to differing peripheral mappings and power domain assignments.
What security features does the R7F7010183AFP#KA4 include for firmware protection?
The R7F7010183AFP#KA4 includes an integrated Intelligent Cryptographic Unit (ICUMD) supporting AES-128/256, SHA-256, and RSA-2048 operations, plus a secure boot ROM that validates digital signatures before loading application firmware.
