Product details
Overview
R7FS5D97E3A01CFB#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 hardware including AES-256, SHA-256, TRNG, and secure boot. It operates at up to 200 MHz, supports USB 2.0 FS/HS, CAN FD, Ethernet MAC, and QSPI interface, and targets industrial HMI, gateway, and secure edge node applications.
For engineers reviewing the R7FS5D97E3A01CFB#AA0 datasheet, R7FS5D97E3A01CFB#AA0 pinout, R7FS5D97E3A01CFB#AA0 application, or R7FS5D97E3A01CFB#AA0 equivalent, this page provides verified package mapping (LQFP-176), confirmed peripheral integration (CAN FD + Ethernet MAC + USB HS), real-time OS support via SSP, and validated alternative options for migration or dual-sourcing.
Technical Context
The R7FS5D97E3A01CFB#AA0 implements a dual-bank Flash architecture with background operation and ECC protection, enabling safe over-the-air updates. Its system clock tree integrates an on-chip FLL, PLL, and multiple clock sources-including external crystal (1–20 MHz), internal RC oscillators, and fractional dividers-for precise timing control across peripherals.
Security is enforced through a dedicated Secure Crypto Engine (SCE7) supporting key wrapping, secure key storage, and tamper detection. The MCU includes a configurable interrupt controller (ICU) with 256 priority levels, nested vector handling, and low-latency wake-up from deep sleep modes (ULP, Deep Software Standby).
