Overview
R7FS5D97C3A01CFB#AA0 from Renesas Electronics is a 32-bit ARM Cortex-M4F-based microcontroller in the Synergy S5 Series, featuring 2 MB flash, 512 KB SRAM, and integrated security peripherals including AES-256, SHA-256, TRNG, and secure boot. It operates at up to 200 MHz, supports USB HS/FS, CAN FD, Ethernet MAC, and QSPI interface, and targets industrial HMI and secure IoT edge nodes.
For engineers reviewing the R7FS5D97C3A01CFB#AA0 datasheet, R7FS5D97C3A01CFB#AA0 pinout, R7FS5D97C3A01CFB#AA0 application, or R7FS5D97C3A01CFB#AA0 equivalent, key selection considerations include its dual-bank secure flash architecture, hardware-accelerated crypto engine, 176-pin LQFP package with configurable I/Os, and support for Renesas Synergy Software Package (SSP) v3.x with certified middleware.
Technical Context
This MCU implements an ARM Cortex-M4F core with FPU and MPU, coupled with a multi-layer AHB/APB bus matrix enabling concurrent peripheral access. Its system-level features include a 24-channel event link controller (ELC), 16-channel DMAC, and real-time OS-aware interrupt controller (NVIC) with 240 priority levels.
The device integrates a dedicated security subsystem with tamper detection, secure key storage, and hardware-enforced secure boot flow verified by ROM-based bootloader. Clock management includes dual PLLs (main and USB), FLL, and independent clock domains for low-power operation with seven power modes - including Deep Software Standby with RTC and 32 KB SRAM retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M4F @ up to 200 MHz with FPU and MPU - enables deterministic floating-point math and memory protection for safety-critical tasks. |
| Memory | 2 MB on-chip flash (dual-bank, ECC-protected) + 512 KB SRAM (32 KB retained in Deep Software Standby) - supports safe firmware updates and low-power data logging. |
| Security | AES-256/SHA-256/TRNG/Secure Boot - provides hardware-accelerated encryption, secure key generation, and immutable root-of-trust verification. |
| Connectivity | USB 2.0 HS/FS, CAN FD (up to 5 Mbps), 10/100 Ethernet MAC, QSPI x2 - enables high-speed wired edge connectivity with protocol flexibility. |
| Peripherals | 16-bit ADC (12 ch), 12-bit DAC (2 ch), 32-bit PWM (6 ch), 24-channel ELC, 16-channel DMAC - supports precise analog sensing, motor control, and event-driven low-latency I/O coordination. |
| Package | 176-pin LQFP (24 × 24 mm, 0.5 mm pitch) - compatible with standard PCB assembly processes and offers full I/O accessibility for complex industrial interfaces. |
Pinout & Package
176-pin LQFP (24 × 24 mm, 0.5 mm pitch), RoHS-compliant, with exposed thermal pad. Pin functions include multiplexed GPIO, analog inputs, clock inputs/outputs, reset, JTAG/SWD debug, USB DP/DM, CANH/CANL, RMII signals, QSPI DQ0–DQ7, and dedicated security pins (TAMPER, VDDA, VREFH/L).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P175 | Configurable GPIO / Peripheral Function Multiplexing | Each pin supports up to 8 alternate functions (e.g., UART, SPI, I²C, timer output); programmable pull-up/down, drive strength, and slew rate via PFS registers. |
| CLKIN / CLKOUT | External Crystal Input / System Clock Output | Accepts 1–20 MHz crystal for main PLL; CLKOUT can mirror PCLKB or PLL output for trace clock synchronization or external timing reference. |
| USB_DP / USB_DM | USB 2.0 High-Speed Differential Pair | Supports HS (480 Mbps) and FS (12 Mbps); internal PHY with suspend/resume detection and SOF generation - eliminates need for external transceiver in most designs. |
| TXD0 / RXD0 | UART Channel 0 Serial Interface | Dedicated full-duplex asynchronous communication port with fractional baud rate generator, FIFO, and LIN break detection - suitable for host diagnostics or sensor bridging. |
| TAMPER0–TAMPER3 | Physical Tamper Detection Inputs | Edge-triggered inputs monitored by security subsystem; any assertion clears secure key registers and forces secure boot revalidation - critical for anti-tamper compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Bank Secure Flash | Enables atomic firmware updates with rollback protection: one bank executes while the other is erased/programmed, verified by CRC and signature check before activation. |
| Hardware Crypto Engine | Offloads AES-256 encryption/decryption, SHA-256 hashing, and TRNG entropy generation from CPU - reduces latency and power vs. software-only implementations. |
| Event Link Controller (ELC) | Allows 24 peripherals to trigger each other without CPU intervention (e.g., ADC conversion completion → DMAC transfer → PWM period update) - achieves sub-microsecond deterministic response. |
| Deep Software Standby Mode | Retains 32 KB SRAM and RTC while consuming ≤1.8 µA - ideal for battery-powered edge nodes requiring periodic wake-up and sensor sampling without full reboot. |
| Secure Boot ROM | Immutable first-stage bootloader validates signed firmware image using ECDSA-P256 before loading into RAM - prevents execution of unauthorized or corrupted code at power-on. |
