Product details
Overview
R7F7016934AFP-C#KA1 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring dual-core lockstep CPU architecture, 4 MB on-chip flash memory, and ASIL-D compliance per ISO 26262 for safety-critical powertrain and chassis control applications. It integrates a 200 MHz core clock, 512 KB SRAM, and hardware safety mechanisms including ECC on flash/SRAM, BIST, and lockstep monitoring.
For engineers reviewing the R7F7016934AFP-C#KA1 datasheet, R7F7016934AFP-C#KA1 pinout, R7F7016934AFP-C#KA1 application, or R7F7016934AFP-C#KA1 equivalent, key selection considerations include its dual-lockstep execution mode, integrated CAN FD (up to 5 channels), Ethernet AVB support, and AEC-Q100 Grade 1 qualification for under-hood deployment.
Technical Context
The R7F7016934AFP-C#KA1 implements a dual-core RH850G3K-H CPU with hardware-enforced lockstep operation, where one core executes instructions while the other verifies results in real time. It supports full ASIL-D fault detection coverage via dedicated safety monitor logic, memory built-in self-test (MBIST), and flash ECC with error correction and notification.
It integrates multiple domain-specific peripherals: five CAN FD controllers with flexible data-rate support up to 5 Mbps, one 100BASE-T1 Ethernet AVB interface with time-sensitive networking (TSN) readiness, and a 12-bit SAR ADC with 48 channels and hardware trigger synchronization. All critical peripherals are safety-monitored and accessible via dedicated safety channels.
