Product details
Overview
R7F7010173AFP#KA2 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring a dual-core lockstep CPU, 1.5 MB on-chip flash memory, 128 KB SRAM, and integrated ASIL-B compliant safety mechanisms including ECC for memory, BIST, and windowed watchdog timers. It supports CAN FD (up to 5 Mbps), LIN, and SENT interfaces, and targets engine control units (ECUs) requiring functional safety certification per ISO 26262 ASIL D.
For engineers reviewing the R7F7010173AFP#KA2 datasheet, R7F7010173AFP#KA2 pinout, R7F7010173AFP#KA2 application, or R7F7010173AFP#KA2 equivalent, key selection criteria include dual-core lockstep execution integrity, ASIL-D ready safety architecture, CAN FD timing compliance, flash endurance (100k write/erase cycles), and qualification per AEC-Q100 Grade 1 (−40°C to +125°C).
Technical Context
The R7F7010173AFP#KA2 implements a dual-core RH850 G3KH CPU executing in lockstep mode with real-time comparison logic to detect transient faults; it includes dedicated safety monitor circuits that validate instruction execution, data path integrity, and memory access consistency across both cores. Its memory subsystem integrates ECC protection for both flash and SRAM, with automatic error correction and fault injection test support via built-in self-test (BIST) engines.
Peripheral integration includes a 12-bit ADC with 32-channel multiplexing, 4x 32-bit timer units supporting PWM generation and input capture, and a multi-channel DMA controller with scatter-gather capability. All safety-critical peripherals are connected to the Safety Management Unit (SMU), which enforces runtime monitoring, error logging, and fail-safe state transitions per ISO 26262 requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7010293AFP#KA2 | 2 MB flash, 192 KB SRAM, same package and pinout; adds second FlexRay channel and enhanced SMU features | Targeted at higher-complexity chassis domain controllers requiring dual FlexRay and extended diagnostic coverage | Select when >1.5 MB flash or dual FlexRay is required; otherwise R7F7010173AFP#KA2 offers optimal cost/performance balance |
| SPC574SNC1AKKU | Power Architecture e200z4 dual-core, 2 MB flash, AEC-Q100 Grade 1, but lacks native CAN FD and uses different safety IP (SafeAssure) | Used in legacy powertrain platforms where Power Architecture toolchain and SPC5 ecosystem are established | Choose only if existing SPC5 software investment or specific Power Architecture compatibility is mandatory |
Compared with R7F7010293AFP#KA2, the R7F7010173AFP#KA2 reduces flash capacity and removes one FlexRay channel to lower BOM cost while retaining full ASIL-D capability and CAN FD performance; versus SPC574SNC1AKKU, it delivers native CAN FD support, tighter timing control, and Renesas' RH850 safety IP stack optimized for ISO 26262 tool qualification.

FAQ
What is the maximum operating frequency of the R7F7010173AFP#KA2?
The R7F7010173AFP#KA2 operates at a maximum CPU frequency of 120 MHz under nominal conditions (VDD = 3.3 V, TA = 25°C). Its PLL supports configurable multiplication ratios to derive this clock from external crystal sources ranging from 4 to 20 MHz. The device maintains timing compliance across its full AEC-Q100 Grade 1 temperature range (−40°C to +125°C), with derating applied above 105°C ambient per Renesas' thermal specifications. This frequency enables deterministic execution of ASIL-D safety routines within strict deadline constraints.
Does the R7F7010173AFP#KA2 support CAN FD, and what data rates are achievable?
Yes, the R7F7010173AFP#KA2 integrates three independent CAN FD controllers compliant with ISO 11898-1:2015. Each controller supports arbitration bit rates up to 1 Mbps and data phase bit rates up to 5 Mbps, with programmable sample points, TDC offset, and transceiver delay compensation. The hardware supports automatic protocol switching between Classical CAN and CAN FD frames, CRC-17 for FD and CRC-15 for Classical CAN, and flexible data length up to 64 bytes. These capabilities are validated in Renesas' RH850/F1KH hardware user manual Rev.1.30.
What safety certifications does the R7F7010173AFP#KA2 target?
The R7F7010173AFP#KA2 is designed to support ISO 26262 ASIL D compliance at the system level. It includes integrated safety mechanisms such as dual-core lockstep CPU execution, ECC for flash and SRAM, hardware BIST, windowed watchdog timers, and a dedicated Safety Management Unit (SMU) with error logging and fail-safe state control. While the IC itself is not "certified," Renesas provides certified safety libraries, FMEDA reports, and hardware safety manuals enabling customers to achieve ASIL D decomposition in end applications like engine ECUs and brake control units.
What is the flash endurance specification for the R7F7010173AFP#KA2?
The R7F7010173AFP#KA2 specifies 100,000 write/erase cycles for its 1.5 MB on-chip flash memory, verified per JEDEC JESD22-A117 stress testing methodology. Each sector supports independent erasure, and wear leveling must be implemented in firmware. Flash programming is performed in 128-byte pages with verify-on-write enabled by default. Endurance applies across the full operating temperature range (−40°C to +125°C), with data retention guaranteed for 20 years at 125°C and 40 years at 85°C per Renesas' reliability documentation.
Is the R7F7010173AFP#KA2 pin-compatible with other RH850/F1KH variants?
The R7F7010173AFP#KA2 uses a 144-pin LQFP package identical in footprint and pin assignment to other RH850/F1KH-D8 variants including R7F7010293AFP#KA2 and R7F7010163AFP#KA2. Pin compatibility is confirmed in Section 2A.1 (Pin Connection Diagram) and Table 2A.1 (Pin Description) of the RH850/F1KH User's Manual Rev.1.30. However, functional differences exist - for example, R7F7010293AFP#KA2 adds a second FlexRay channel - so PCB reuse requires verification of peripheral enablement and register mapping in software.
