Product details
Overview
R7FS3A17C2A01CLK#BC0 from Renesas Electronics is a 32-bit ARM Cortex-M4F-based microcontroller in the Synergy S3 Series, featuring 1 MB Flash, 256 KB SRAM, integrated FPU, and hardware AES/SHA/ECDSA security accelerators. It operates at up to 48 MHz, supports USB 2.0 FS, CAN FD, and multiple serial interfaces (SCI, SPI, I²C), and targets secure industrial HMI and sensor gateway applications.
For engineers reviewing the R7FS3A17C2A01CLK#BC0 datasheet, R7FS3A17C2A01CLK#BC0 pinout, R7FS3A17C2A01CLK#BC0 application, or R7FS3A17C2A01CLK#BC0 equivalent, this page delivers verified package mapping (LQFP-100), confirmed peripheral set (USB + CAN FD + 12-bit ADC), real-time clock with calendar function, and validated alternative options for migration or second sourcing.
Technical Context
The R7FS3A17C2A01CLK#BC0 implements a dual-bus AHB/APB architecture with tightly coupled memory for deterministic interrupt latency. Its system includes a 48 MHz PLL with fractional divider, independent low-power modes (SNOOZE, DEEP-SLEEP), and a configurable interrupt controller supporting 128 vectorized IRQs with priority grouping.
Security is enforced via TrustZone-enabled memory protection unit (MPU), tamper detection pins, and dedicated cryptographic engine supporting AES-128/256, SHA-256, and ECDSA signature generation/verification - all operating without CPU intervention. The device integrates a 12-bit, 1.0 MSps ADC with hardware averaging and window comparison.
