For engineers reviewing the R7F7010184AFP-C#KA4 datasheet, R7F7010184AFP-C#KA4 pinout, R7F7010184AFP-C#KA4 application, or R7F7010184AFP-C#KA4 equivalent, key selection criteria include ASIL-B functional safety compliance, dual-core lockstep execution integrity, CAN FD interface timing, flash endurance (100k write/erase cycles), and operating junction temperature range (–40°C to +150°C).
Technical Context
The R7F7010184AFP-C#KA4 implements a dual-core RH850 G3KH CPU in lockstep mode with hardware-based comparison logic and error signaling via dedicated safety interrupt lines. It integrates a multi-channel DMA controller supporting scatter-gather transfers and peripheral-to-peripheral chaining without CPU intervention.
Its safety architecture includes memory protection units (MPU) with configurable regions, runtime self-test (RTS) for CPU core and bus interconnects, and independent clock domain monitoring for system and peripheral clocks. The device uses a 5V-tolerant I/O structure compatible with 3.3V core logic and supports voltage supervision across VCC, VDD, and AVCC rails.

Each supports arbitration bit rates up to 1 Mbps and data bit rates up to 5 Mbps, with programmable bit timing, automatic retransmission, and CRC-17/CRC-21 calculation. The R7F7010184AFP-C#KA4 CAN FD modules include built-in loopback modes for self-test and support both classic CAN and FD frames on the same bus without protocol translation. All CAN FD features are accessible via the RH850 G3KH peripheral library included in Renesas' e2 studio IDE.
How is functional safety implemented in R7F7010184AFP-C#KA4 for ASIL-B compliance?
R7F7010184AFP-C#KA4 achieves ASIL-B compliance through hardware-enforced dual-core lockstep execution, SEC-DED SRAM, ECC-protected flash, memory protection units (MPU), windowed watchdog timers, clock domain monitoring, and built-in self-test (BIST) for CPU and bus interconnects. Its safety manual documents 98.7% diagnostic coverage for CPU and memory subsystems, and all safety mechanisms are independently verified per ISO 26262 Part 5. The R7F7010184AFP-C#KA4 includes dedicated safety interrupt outputs and failsafe state entry logic that meets ASIL-B fault reaction requirements.
What is the flash endurance specification for R7F7010184AFP-C#KA4?
R7F7010184AFP-C#KA4 guarantees 100,000 write/erase cycles for its 1.5 MB on-chip flash memory across the full operating temperature range (–40°C to +150°C). This endurance rating is validated per JEDEC JESD22-A117 and includes margin for wear leveling algorithms implemented in Renesas' Flash API. The flash supports page erase (256 bytes), sector erase (4 KB), and full chip erase, with typical program time of 50 µs per 128-bit word. All R7F7010184AFP-C#KA4 flash operations are protected by ECC and monitored for programming errors in real time.
Is R7F7010184AFP-C#KA4 pin-compatible with other RH850/F1KH variants?
R7F7010184AFP-C#KA4 is pin-compatible with the R7F7010284AFP-C#KA4 (2 MB flash) and R7F7010084AFP-C#KA4 (1 MB flash) in the same 144-pin LQFP package. All share identical pin functions, electrical characteristics, and mechanical footprint. However, it is not pin-compatible with RH850/F1KM series devices due to differences in peripheral mapping and safety signal routing. Pin compatibility is confirmed in Renesas' RH850/F1KH Pin Function User's Manual Rev.1.30, Section 2A.2.
