Overview
R7FS1JA783A01CNE#BA0 from Renesas Electronics is a 32-bit Arm® Cortex®-M23-based microcontroller in the Synergy S1 Series, featuring 1 MB Flash, 256 KB SRAM, and integrated AES-256/SHA-256 cryptographic accelerators. It operates at up to 48 MHz, supports USB Full-Speed Device, CAN FD, and includes 12-bit ADC with 24 channels - deployed in industrial HMI, smart sensors, and secure edge node applications.
For engineers reviewing the R7FS1JA783A01CNE#BA0 datasheet, R7FS1JA783A01CNE#BA0 pinout, R7FS1JA783A01CNE#BA0 application, or R7FS1JA783A01CNE#BA0 equivalent, key selection criteria include its TrustZone-enabled security architecture, CAN FD timing compliance (ISO 11898-1:2015), USB device stack readiness, and support for SSP v3.x firmware integration in resource-constrained embedded designs.
Technical Context
The R7FS1JA783A01CNE#BA0 implements Arm TrustZone for Armv8-M to isolate secure/non-secure firmware execution domains, with dedicated secure boot ROM and hardware key storage. Its system clock tree integrates FLL and PLL for precise frequency synthesis across USB, CAN FD, and peripheral bus domains.
Peripheral integration includes a 12-bit SAR ADC with hardware averaging and window comparison, dual 16-bit general-purpose timers with quadrature encoder input, and a configurable serial interface supporting UART, SPI, I²C, and LIN modes - all accessible via PFS register-controlled pin multiplexing.
