Product details
Overview
R7FS1JA783A01CNF#BA0 from Renesas Electronics is a 32-bit Arm® Cortex®-M23-based microcontroller in the Synergy S1JA Group, featuring 1 MB Flash, 256 KB SRAM, and integrated AES-256/SHA-256 cryptographic accelerators. It operates at up to 48 MHz, supports USB 2.0 FS device mode, and targets secure industrial sensing and HMI edge nodes requiring certified firmware integrity.
For engineers reviewing the R7FS1JA783A01CNF#BA0 datasheet, R7FS1JA783A01CNF#BA0 pinout, R7FS1JA783A01CNF#BA0 application, or R7FS1JA783A01CNF#BA0 equivalent, this page delivers verified package mapping (LQFP-100), confirmed peripheral set (12-bit ADC ×2, 16-bit PWM ×2, SCI ×6), security features (TRNG, secure boot ROM), and real-world substitution guidance against functionally aligned alternatives.
Technical Context
The R7FS1JA783A01CNF#BA0 implements TrustZone® for Armv8-M to isolate secure and non-secure execution states, with hardware-enforced memory protection and secure boot enforced by immutable ROM code. Its system clock tree integrates FLL, PLL, and multiple independent clock domains for peripheral gating and low-power operation.
It includes a dedicated Secure Crypto Engine supporting AES-256 ECB/CBC/CTR/GCM, SHA-256, and RSA-2048 signature verification - all accessible only from the secure state. The MCU integrates 12-bit SAR ADCs with hardware averaging and window comparison, plus dual 16-bit timer units supporting complementary PWM output with dead-time insertion.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS1JA782A01CNF#BA0 | Same S1JA family, but 512 KB Flash and 128 KB SRAM; identical peripheral set and security engine. | Suitable for cost-sensitive designs with smaller firmware footprint and reduced RAM requirements. | Select when application firmware fits within 512 KB and does not require dual-bank OTA or large sensor buffers. |
| R7FA6M2AF3CFP#AA0 | RA6M2-based (Cortex-M4F), 1 MB Flash, 256 KB SRAM, no TrustZone, includes FPU and higher clock (100 MHz). | Better suited for floating-point math (e.g., predictive maintenance algorithms) but lacks hardware-enforced secure state isolation. | Choose when computational throughput outweighs mandatory hardware security partitioning; requires external crypto SW stack. |
Compared with R7FS1JA783A01CNF#BA0, the R7FS1JA782A01CNF#BA0 offers identical security and peripherals at lower memory cost, while the R7FA6M2AF3CFP#AA0 trades TrustZone for higher performance and FPU - making it appropriate for algorithm-heavy but less security-critical edge analytics.

FAQ
Does R7FS1JA783A01CNF#BA0 support USB host functionality?
No, R7FS1JA783A01CNF#BA0 implements only USB 2.0 Full-Speed device mode with integrated PHY and endpoint FIFOs. It lacks OTG or host controller logic, so it cannot enumerate as a USB host or support peripheral attachment like keyboards or flash drives. For host capability, consider RA6Mx-series MCUs with USB host stack support.
What debug interfaces are supported by R7FS1JA783A01CNF#BA0?
R7FS1JA783A01CNF#BA0 supports Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins, compliant with ARM CoreSight standards. It does not support JTAG. Debug access is gated by secure boot policy: non-secure debug is disabled unless explicitly enabled in secure state configuration, preserving firmware confidentiality during development and field service.
Is R7FS1JA783A01CNF#BA0 qualified for automotive applications?
No, R7FS1JA783A01CNF#BA0 is rated for industrial temperature range (−40°C to +105°C) and classified as "Standard" quality grade per Renesas documentation. It is not AEC-Q100 qualified and lacks automotive-specific features such as enhanced ESD immunity or extended qualification testing required for under-hood or safety-critical vehicle systems.
Can R7FS1JA783A01CNF#BA0 execute code directly from RAM?
Yes, R7FS1JA783A01CNF#BA0 supports XIP (execute-in-place) from Flash and also allows loading and executing application code from its 256 KB SRAM. This is used for time-critical routines, secure boot verification, or dynamic firmware patching - subject to MPU configuration and TrustZone memory region permissions.
What is the maximum resolution and sampling rate of the ADC in R7FS1JA783A01CNF#BA0?
R7FS1JA783A01CNF#BA0 integrates two independent 12-bit SAR ADCs, each capable of up to 1.1 MSPS aggregate sampling rate when using hardware triggers and continuous conversion mode. Resolution remains fixed at 12 bits; oversampling or hardware averaging can improve effective resolution but does not increase native bit depth.
