Product details
Overview
R7FS5D97E3A01CFC#AA1 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 FPU, and hardware-accelerated AES-256/SHA-256 cryptographic engine. It supports USB 2.0 FS, CAN FD, multiple UART/SPI/I²C interfaces, and operates at up to 240 MHz for real-time industrial HMI and secure edge node applications.
For engineers reviewing the R7FS5D97E3A01CFC#AA1 datasheet, R7FS5D97E3A01CFC#AA1 pinout, R7FS5D97E3A01CFC#AA1 application, or R7FS5D97E3A01CFC#AA1 equivalent, key selection considerations include its dual-bank flash architecture for safe OTA updates, TrustZone-enabled secure boot, 12-bit ADC with 1 MSps sampling, and support for Renesas Synergy Software Package (SSP) v3.x with certified middleware.
Technical Context
This MCU implements an ARMv7E-M architecture with tightly coupled memory (TCM), configurable cache (I-Cache/D-Cache), and a multi-layer AHB/APB bus matrix enabling concurrent peripheral access. Its system control includes programmable voltage regulators, multiple clock sources (PLL, FLL, LOCO, HOCO, MOCO), and a sophisticated power management unit supporting 11 low-power modes including Deep Software Standby with RTC wake-up.
The peripheral set integrates a 24-channel event link controller (ELC) for deterministic interrupt-free signal chaining, a 32-channel DMA controller with scatter-gather support, and a high-precision 32-bit PWM timer (GPT) with dead-time insertion and complementary output - all synchronized via shared clock domains and configurable gating.
