Product details
Overview
R7F7010083AFP#AA2 from Renesas Electronics is a 32-bit automotive-grade MCU in the RH850/F1KH-D8 family, featuring a dual-core lockstep CPU architecture, 1.25 MB on-chip flash memory, and integrated ASIL-B compliant safety mechanisms including ECC for RAM/flash, lockstep monitoring, and BIST. It operates at up to 120 MHz and supports CAN FD, LIN, and SENT interfaces for powertrain and chassis control applications.
For engineers reviewing the R7F7010083AFP#AA2 datasheet, R7F7010083AFP#AA2 pinout, R7F7010083AFP#AA2 application, or R7F7010083AFP#AA2 equivalent, key selection criteria include ASIL-B functional safety certification, dual-core lockstep execution integrity, flash ECC coverage, CAN FD data-rate support up to 5 Mbps, and qualification per AEC-Q100 Grade 1 (−40°C to +125°C).
Technical Context
The R7F7010083AFP#AA2 implements a dual-core RH850 G3KH CPU with hardware-enforced lockstep operation, where one core executes instructions while the other verifies results in real time. It integrates a 12-channel 12-bit ADC with simultaneous sampling, 4x SENT receivers, and 2x CAN FD controllers supporting ISO 11898-1:2015 with bit rates up to 5 Mbps.
Safety features include lockstep error detection logic, flash and SRAM ECC with single-bit correction/double-bit detection, built-in self-test (BIST) for CPU and memory, and configurable watchdog timers with windowing. The device uses a 176-pin LQFP package with dedicated safety pins (e.g., LOCKSTEP_ERR, SAFETY_RST) routed separately for fault isolation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7010283AFP#AA2 | Same RH850/F1KH-D8 family, but with 2 MB flash and 256 KB RAM - no change in CPU, safety features, or peripheral set. | Required when firmware image size exceeds 1.25 MB or additional RAM is needed for complex diagnostics. | Select if future firmware growth or enhanced logging capability is anticipated; otherwise, R7F7010083AFP#AA2 offers optimal cost/performance balance. |
| SPC574S54E3 | STMicroelectronics 32-bit Power Architecture MCU with ASIL-B support, 2 MB flash, but single-core with software-based safety checks. | Lacks hardware lockstep; relies on compiler-inserted redundancy and periodic BIST - higher software verification burden. | Choose only if existing toolchain alignment with SPC5 or legacy Power Architecture integration outweighs lockstep determinism benefits. |
Compared with R7F7010283AFP#AA2, the R7F7010083AFP#AA2 reduces flash/RAM capacity without compromising lockstep safety or CAN FD performance - making it ideal for cost-sensitive ASIL-B modules.

It includes hardware lockstep CPU execution, flash and SRAM ECC, lockstep error signaling via LOCKSTEP_ERR pin, and a certified safety manual with FMEDA data. Renesas provides ASIL-B ready documentation, but final system-level compliance depends on implementation per ISO 26262 Part 6.
Does the R7F7010083AFP#AA2 support CAN FD at full 5 Mbps data rate?
Yes, the R7F7010083AFP#AA2 integrates two CAN FD controllers compliant with ISO 11898-1:2015, each supporting arbitration bit rates up to 1 Mbps and data phase bit rates up to 5 Mbps. This capability is confirmed in the RH850/F1KH Hardware User's Manual Rev.1.30, Section 1A.2 and Table 2A.2-1 for pin assignments.
What is the purpose of the LOCKSTEP_ERR pin on the R7F7010083AFP#AA2?
The LOCKSTEP_ERR pin on the R7F7010083AFP#AA2 is an open-drain output that asserts low upon detection of a CPU instruction result mismatch between the primary and checker cores. It enables immediate hardware-triggered fail-safe actions - such as disabling power stages or activating backup controllers - without software intervention, critical for meeting ASIL-B fault reaction time targets.
How much on-chip flash memory does the R7F7010083AFP#AA2 have, and is it ECC-protected?
The R7F7010083AFP#AA2 contains 1.25 MB of on-chip flash memory, fully protected by hardware ECC capable of single-bit correction and double-bit detection. This ECC coverage is active during both read and write operations and is integral to the device's ASIL-B safety architecture, as documented in the RH850/F1KH Hardware User's Manual Section 1A.1 and Section 13.2.1.
Is the R7F7010083AFP#AA2 qualified for under-hood automotive environments?
