Product details
Overview
R7FS5D97C3A01CLK#AC0 from Renesas Electronics is a 32-bit ARM Cortex-M4F-based microcontroller in the Synergy S5 Series, featuring 2 MB flash, 512 KB SRAM, integrated AES-256/SHA-256/TRNG security engines, and dual CAN FD interfaces. It operates at up to 240 MHz, supports industrial temperature range (−40°C to +105°C), and targets secure, real-time embedded control in industrial automation and connected edge devices.
For engineers reviewing the R7FS5D97C3A01CLK#AC0 datasheet, R7FS5D97C3A01CLK#AC0 pinout, R7FS5D97C3A01CLK#AC0 application, or R7FS5D97C3A01CLK#AC0 equivalent, key selection considerations include its dual CAN FD support with time-triggered communication capability, hardware-accelerated cryptographic execution, and integrated Ethernet MAC with IEEE 1588 timestamping - all critical for deterministic industrial networking and secure firmware updates.
Technical Context
The R7FS5D97C3A01CLK#AC0 implements a dual-bank flash architecture enabling safe over-the-air (OTA) updates with zero downtime via bank swapping. Its system clock tree integrates an on-chip FLL and PLL, supporting precise clock generation from internal RC or external crystal sources (1–20 MHz).
Peripheral subsystems include a 12-bit ADC with 16 channels and 1 μs conversion time, three 32-bit general-purpose timers with quadrature encoder input, and a flexible serial interface (FSI) supporting SPI/I²C/UART modes with independent baud rate generators per channel.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS5D97E3A01CLK#AC0 | Same die, but with 4 MB flash and identical peripherals - no change in pinout, timing, or voltage specs. | Required where larger OTA image storage or extended bootloader partitioning is needed. | Select when future firmware growth exceeds 2 MB or dual-bank update requires >1 MB per bank. |
| R7FA6M5BH3CFC#AA0 | RA6M5 series (Cortex-M33), 1 MB flash, single CAN FD, no Ethernet MAC - different security IP (TrustZone instead of Synergy SSP). | Suitable for cost-sensitive, non-Ethernet edge nodes requiring PSA Level 2 certification. | Choose for lower BOM cost and Arm TrustZone-based security if IEEE 1588 or dual CAN FD is not required. |
Compared with R7FS5D97C3A01CLK#AC0, the R7FS5D97E3A01CLK#AC0 offers double flash capacity without layout or firmware changes, while the R7FA6M5BH3CFC#AA0 trades Ethernet and dual CAN FD for Arm TrustZone isolation and lower power - making it viable only where network determinism and bandwidth are relaxed.

FAQ
What is the maximum operating frequency of the R7FS5D97C3A01CLK#AC0?
The R7FS5D97C3A01CLK#AC0 operates at a maximum CPU frequency of 240 MHz using its on-chip PLL. This frequency is achievable with proper power supply decoupling and thermal management within the specified industrial temperature range (−40°C to +105°C). The R7FS5D97C3A01CLK#AC0 supports dynamic clock scaling to reduce power consumption during low-activity periods without compromising real-time responsiveness.
Does the R7FS5D97C3A01CLK#AC0 support secure boot from factory default?
Yes, the R7FS5D97C3A01CLK#AC0 includes a one-time-programmable (OTP) secure boot ROM that validates the digital signature of the initial bootloader using a factory-programmed public key. This immutable root-of-trust ensures only authenticated firmware executes at power-on. The R7FS5D97C3A01CLK#AC0 also supports user-configurable boot source selection (flash, QSPI, or SD card) with signature verification enforced for each path.
What Ethernet capabilities does the R7FS5D97C3A01CLK#AC0 provide?
The R7FS5D97C3A01CLK#AC0 integrates a full IEEE 802.3-compliant 10/100 Mbps Ethernet MAC with hardware support for IEEE 1588-2008 (v2) Precision Time Protocol, including timestamping of sync, delay_req, and pdelay_req messages at the MAC layer. It does not include a physical layer (PHY); an external 10/100BASE-TX PHY must be used. The R7FS5D97C3A01CLK#AC0 supports MII and RMII interfaces with configurable clock outputs.
Can the R7FS5D97C3A01CLK#AC0 perform over-the-air (OTA) firmware updates safely?
Yes, the R7FS5D97C3A01CLK#AC0 supports safe OTA updates via its dual-bank flash architecture. New firmware images are written to the inactive bank while the current version runs from the active bank. Upon successful verification, the R7FS5D97C3A01CLK#AC0 performs an atomic bank swap at reset - ensuring no invalid state or partial update can execute. This mechanism is managed by the Synergy Software Package (SSP) bootloader.
What development tools are officially supported for the R7FS5D97C3A01CLK#AC0?
Renesas officially supports the E2 Studio IDE with Synergy Software Package (SSP) v3.x for the R7FS5D97C3A01CLK#AC0. Hardware debugging uses the Segger J-Link PRO or Renesas E2 Lite emulator via SWD interface. The S5D5-DB Development Board (YRDKSN5D5) provides full evaluation of all peripherals, including Ethernet, CAN FD, and crypto acceleration. The R7FS5D97C3A01CLK#AC0 is also supported in IAR Embedded Workbench and Arm Keil MDK.
