Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7010424AFP-C#AA2 | Same package and pinout; adds 512 KB additional SRAM and second FlexRay channel | Required for complex brake-by-wire systems needing dual FlexRay domains | Select when >384 KB RAM or dual FlexRay is mandatory; otherwise R7F7010423AFP-C#AA2 offers optimal cost/performance balance |
| SPC5744PFK1AKLQ1 | Power Architecture e200z4 core, 180 MHz, 2 MB flash, 384 KB RAM, but no SENT or ICUMD hardware accelerator | Lacks native SENT interface and cryptographic hardware; relies on software AES/SHA | Choose only if existing SPC5 toolchain and AUTOSAR stack are already deployed; R7F7010423AFP-C#AA2 provides superior security and sensor interface integration |
Compared with R7F7010424AFP-C#AA2, the R7F7010423AFP-C#AA2 reduces BOM cost by omitting redundant SRAM and FlexRay while retaining full ASIL-B compliance and SENT support.

Does R7F7010423AFP-C#AA2 support AUTOSAR-compliant MCAL drivers?
Yes, R7F7010423AFP-C#AA2 is fully supported by Renesas' official AUTOSAR 4.3 MCAL stack, including drivers for CAN FD, LIN, SENT, ADC, DIO, GPT, ICU, and ETH. The MCAL package includes configuration tools compatible with ETAS ISOLAR-A and Vector DaVinci Configurator, and has been validated with EB tresos and Green Hills INTEGRITY AUTOSAR OS.
What debug interface does R7F7010423AFP-C#AA2 use, and is JTAG available?
R7F7010423AFP-C#AA2 uses the standard RH850 Debug Interface (RDI) over JTAG, supporting IEEE 1149.1 boundary scan and full real-time debugging via Renesas E2 emulator. JTAG pins (TCK, TMS, TDI, TDO, TRST) are multiplexed on Port 0 pins and require proper termination and routing per Renesas Hardware Design Guide Rev.1.30 Section 2A.2. SWD is not supported.
Can R7F7010423AFP-C#AA2 execute code from RAM, and what is the boot process?
Yes, R7F7010423AFP-C#AA2 supports XIP (eXecute-In-Place) from flash and also allows copying and executing application code from SRAM. Boot begins from on-chip ROM bootloader, which validates flash signature using ICUMD before transferring control to user application at 0x0000_0000. Secure boot can be enabled via fuse settings to enforce signed firmware images.
Is there hardware support for SENT protocol decoding in R7F7010423AFP-C#AA2?
Yes, R7F7010423AFP-C#AA2 includes dedicated SENT receiver hardware (SENTRX module) compliant with SAE J2716 rev 2010.
