For engineers reviewing the R7FS3A17C3A01CFB#AA0 datasheet, R7FS3A17C3A01CFB#AA0 pinout, R7FS3A17C3A01CFB#AA0 application, or R7FS3A17C3A01CFB#AA0 equivalent, this page delivers verified specifications, package mapping to 144-pin LQFP (20 mm × 20 mm, 0.5 mm pitch), functional pin roles, safety-certifiable peripherals (ECC SRAM, IWDT, CAC), and direct alternatives for migration or second-sourcing.
Technical Context
This MCU implements an Armv7E-M architecture with DSP extensions and single-precision FPU, supporting deterministic real-time execution up to 48 MHz. It integrates dual watchdogs (WDT and independent IWDT), memory protection via 8-region MPU, and hardware-accelerated security including AES128/256, GHASH, and TRNG.
The system combines high-resolution analog (ADC14 with 26 channels, DAC12, ACMPLP ×2, OPAMP ×4) with flexible connectivity: 6× SCI (UART/IIC/SPI), 3× I2C, 2× SPI, CAN 2.0B, QSPI, SDHI, SSIE, and USBFS with on-chip transceiver and Battery Charging 1.2 compliance - all coordinated via Event Link Controller (ELC) for CPU-free peripheral interaction.
