Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F701382EAFP-C#KA2 | Same RH850/P1M-E family, identical pinout and lockstep architecture, but with 2 MB flash and 256 KB RAM | Suitable for mid-tier powertrain ECUs where reduced memory footprint is acceptable | Select when BOM cost sensitivity outweighs need for full 3 MB flash capacity and extended diagnostic logging buffer |
| TC397XP-160F300N DC | AURIX™ TC3xx tri-core architecture (2x TriCore + 1x Cortex-M7), 300 MHz, 8 MB flash, no native SENT/PSI5 hardware | Targeted at high-end ADAS and zonal controllers requiring higher compute throughput and Ethernet TSN | Choose when application demands >200 MHz real-time performance and requires Ethernet TSN stack support over CAN FD |
Compared with R7F701383EAFP-C#KA2, the R7F701382EAFP-C#KA2 offers identical safety architecture and peripheral set at lower memory density, while the TC397XP provides higher compute bandwidth but requires external SENT/PSI5 interface ICs and lacks native lockstep dual-core verification.

FAQ
What is the maximum operating frequency of the R7F701383EAFP-C#KA2?
The R7F701383EAFP-C#KA2 operates at a maximum frequency of 160 MHz under specified voltage and temperature conditions. This frequency is achieved using its on-chip PLL with programmable multiplication ratio and supports dynamic voltage/frequency scaling for thermal management. The dual-core lockstep operation maintains timing integrity at this speed, and all peripherals-including CAN FD, ADC, and timers-are fully synchronized to this clock domain. The R7F701383EAFP-C#KA2 datasheet specifies setup/hold margins validated across automotive temperature range (−40°C to 125°C).
Does the R7F701383EAFP-C#KA2 support ISO 26262 ASIL-D certification out of the box?
The R7F701383EAFP-C#KA2 is designed to meet ISO 26262 ASIL-D requirements and includes hardware safety mechanisms such as dual-core lockstep execution, PE Guard, IPG, and SEG. However, full ASIL-D certification depends on system-level integration, software safety analysis, and tool qualification-none of which are provided by the R7F701383EAFP-C#KA2 alone. Renesas supplies safety manuals, FMEDA reports, and diagnostic software libraries to support customer certification efforts for the R7F701383EAFP-C#KA2.
How many CAN FD channels does the R7F701383EAFP-C#KA2 integrate?
The R7F701383EAFP-C#KA2 integrates five independent CAN FD controllers compliant with ISO 11898-1:2015 and SAE J2284-4. Each channel supports data rates up to 5 Mbps, flexible data field lengths (up to 64 bytes), and built-in protocol handling including automatic retransmission, error confinement, and loopback self-test modes. These five channels are accessible via dedicated TX/RX pins and can operate concurrently without CPU intervention using the integrated DMA controller in the R7F701383EAFP-C#KA2.
What type of package does the R7F701383EAFP-C#KA2 use?
The R7F701383EAFP-C#KA2 uses a 176-pin LQFP package (24 mm × 24 mm, 0.5 mm pitch) with an exposed thermal pad on the underside for enhanced heat dissipation. This package meets AEC-Q100 Grade 1 qualification (−40°C to +125°C ambient) and supports standard surface-mount assembly processes. Pin assignments-including power, ground, I/O, and debug interfaces-are documented in the RH850/P1M-E User's Manual Hardware, and the R7F701383EAFP-C#KA2 shares pin compatibility with other members of the RH850/P1M-E family in the same package variant.
Does the R7F701383EAFP-C#KA2 include hardware support for SENT and PSI5 sensor interfaces?
Yes, the R7F701383EAFP-C#KA2 includes dedicated hardware blocks for both SENT (SAE J2716) and PSI5 (ISO 21810) protocols. It supports up to four SENT receivers with timestamping and CRC validation, and two PSI5 receivers with configurable frame timing, wake-up detection, and multi-drop addressing. These interfaces operate independently of the CPU core, enabling low-latency sensor data acquisition with minimal firmware overhead. This hardware acceleration is confirmed in the RH850/P1M-E User's Manual and applies specifically to the R7F701383EAFP-C#KA2.
