Product details
Overview
R7FS5D97E3A01CFC#AA0 from Renesas Electronics is a 32-bit ARM Cortex-M4F-based microcontroller in the Synergy S5 Series, featuring 3MB flash, 512KB SRAM, and integrated hardware encryption (AES-256, SHA-256, TRNG). It supports USB 2.0 FS host/device, CAN FD, Ethernet MAC, and operates at up to 240 MHz for real-time industrial HMI and secure gateway applications.
For engineers reviewing the R7FS5D97E3A01CFC#AA0 datasheet, R7FS5D97E3A01CFC#AA0 pinout, R7FS5D97E3A01CFC#AA0 application, or R7FS5D97E3A01CFC#AA0 equivalent, key selection criteria include its dual-bank flash for safe firmware updates, TrustZone-enabled secure boot, and 10/100 Ethernet with IEEE 1588 timestamping support - critical for time-sensitive industrial networking.
Technical Context
This MCU implements an ARM Cortex-M4F core with FPU and DSP extensions, coupled with a multi-layer AHB/APB bus matrix enabling concurrent access to peripherals including dual QSPI interfaces, SDHI, and 16-bit ADC with hardware averaging. Its system architecture includes a dedicated security subsystem (SCE7) compliant with FIPS PUB 140-2 Level 1.
The device integrates a full-featured Ethernet MAC with MII/RMII PHY interface support, CAN FD controller with bit rate switching up to 5 Mbps, and USB 2.0 FS transceiver with internal PHY - all independently clocked and DMA-capable to offload CPU bandwidth in protocol-rich edge nodes.

FAQ
What is the maximum operating frequency of the R7FS5D97E3A01CFC#AA0?
The R7FS5D97E3A01CFC#AA0 operates at a maximum core frequency of 240 MHz using its on-chip PLL, derived from either an external crystal (1–20 MHz) or internal FLL. This frequency is fully supported across industrial temperature range (−40°C to +85°C) with appropriate voltage scaling (VDD = 3.3 V ±10%). The R7FS5D97E3A01CFC#AA0 maintains timing compliance under worst-case process/voltage/temperature corners per Renesas datasheet AC characteristics.
Does the R7FS5D97E3A01CFC#AA0 support secure boot with cryptographic verification?
Yes, the R7FS5D97E3A01CFC#AA0 implements hardware-enforced secure boot using its SCE7 security module. It verifies ECDSA-signed firmware images stored in flash against immutable public keys programmed into the device during manufacturing. The R7FS5D97E3A01CFC#AA0 performs this check before releasing the Cortex-M4F core from reset, ensuring only authenticated code executes - a requirement for IEC 62443-3-3 compliance.
Can the R7FS5D97E3A01CFC#AA0 run both CAN FD and Ethernet simultaneously without performance degradation?
Yes, the R7FS5D97E3A01CFC#AA0 supports concurrent CAN FD (up to 5 Mbps) and 10/100 Ethernet operation using independent DMA channels and dedicated bus arbitration. Benchmarks show <2% CPU utilization overhead when both peripherals sustain full-rate traffic - enabled by its multi-layer AHB/APB interconnect and hardware queue management in each peripheral's controller. The R7FS5D97E3A01CFC#AA0 maintains deterministic latency for time-critical CAN FD frames even during Ethernet packet bursts.
What development tools are officially supported for the R7FS5D97E3A01CFC#AA0?
Renesas officially supports the R7FS5D97E3A01CFC#AA0 with e2 studio IDE, Synergy Software Package (SSP) v3.x, and the Synergy Development Environment (SDE). Hardware tools include the SK-S5D9 starter kit and J-Link-based debug probes compatible with SWD interface. The R7FS5D97E3A01CFC#AA0 is also validated with IAR Embedded Workbench and Arm Keil MDK, with BSPs and HAL drivers provided in SSP.
Is the R7FS5D97E3A01CFC#AA0 qualified for automotive applications?
No, the R7FS5D97E3A01CFC#AA0 is rated for industrial temperature range (−40°C to +85°C) and classified as "Standard" grade per Renesas quality policy - intended for industrial automation, building control, and consumer infrastructure. It is not AEC-Q100 qualified nor designed for automotive powertrain or ADAS systems. For automotive use, Renesas recommends RH850 or RA8 series devices instead of the R7FS5D97E3A01CFC#AA0.
