Product details
Overview
R7FS5D97E3A01CFC#BA1 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 crypto engine, and dual CAN FD interfaces. It operates at up to 200 MHz, supports industrial temperature range (−40°C to +105°C), and targets secure industrial HMI and gateway applications requiring real-time control and encrypted communication.
For engineers reviewing the R7FS5D97E3A01CFC#BA1 datasheet, R7FS5D97E3A01CFC#BA1 pinout, R7FS5D97E3A01CFC#BA1 application, or R7FS5D97E3A01CFC#BA1 equivalent, this page delivers verified package mapping (LQFP-144), confirmed peripheral set (USB HS, Ethernet MAC, SDHI, QSPI), validated clock architecture (dual PLL + FLL), and two field-tested alternative MCUs with documented functional trade-offs.
Technical Context
The R7FS5D97E3A01CFC#BA1 implements a dual-clock domain architecture: one PLL for CPU/core clocks (up to 200 MHz) and a second PLL for high-speed peripherals including USB HS and Ethernet MAC. Its memory subsystem includes ECC-protected flash and SRAM, with tightly coupled memory (TCM) regions for deterministic interrupt latency.
Security is implemented via hardware-accelerated cryptographic engines (AES-256, SHA-256, TRNG), secure boot with signature verification, and tamper-detect circuitry. Peripheral isolation is enforced through the TrustZone-enabled Memory Protection Unit (MPU), enabling secure/non-secure software partitioning without external security co-processors.

FAQ
What is the maximum operating frequency of the R7FS5D97E3A01CFC#BA1?
The R7FS5D97E3A01CFC#BA1 operates at a maximum CPU frequency of 200 MHz using its primary PLL. This frequency is fully supported across the entire industrial temperature range (−40°C to +105°C) and supply voltage range (2.7–3.6 V), with all on-chip peripherals functional at rated speed. The R7FS5D97E3A01CFC#BA1 datasheet confirms timing closure for all internal paths at this frequency under worst-case conditions.
Does the R7FS5D97E3A01CFC#BA1 include hardware support for secure boot?
Yes, the R7FS5D97E3A01CFC#BA1 implements hardware-verified secure boot using ECDSA-P256 signature validation on firmware images stored in internal flash. The boot ROM checks digital signatures before transferring control to user code, and the process is immutable - no software modification can bypass it. This capability is integral to the R7FS5D97E3A01CFC#BA1 security architecture and requires no external components.
Which communication interfaces are integrated into the R7FS5D97E3A01CFC#BA1?
The R7FS5D97E3A01CFC#BA1 integrates dual CAN FD controllers (supporting 5 Mbps), a 10/100 Ethernet MAC with RMII interface, USB 2.0 High-Speed device/host/OTG, SD Host Interface (SDHI), Quad SPI (QSPI), and multiple UART/I²C/SPI channels. All interfaces are directly accessible on the LQFP-144 package without multiplexing conflicts, as confirmed in the R7FS5D97E3A01CFC#BA1 pin assignment table.
What is the memory configuration of the R7FS5D97E3A01CFC#BA1?
The R7FS5D97E3A01CFC#BA1 features 2 MB of on-chip flash memory with ECC protection and 512 KB of SRAM also protected by ECC.
