Product details
Overview
R7FS1JA783A01CFJ#AA0 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 2.0 FS device mode, and targets secure industrial HMI and sensor-edge applications with its configurable safety peripherals and TrustZone®-enabled secure boot.
For engineers reviewing the R7FS1JA783A01CFJ#AA0 datasheet, R7FS1JA783A01CFJ#AA0 pinout, R7FS1JA783A01CFJ#AA0 application, or R7FS1JA783A01CFJ#AA0 equivalent, key selection criteria include its dual-bank Flash for safe firmware updates, hardware TRNG, 12-bit ADC with 16 channels, and support for IEC 61508 SIL2-ready functional safety features.
Technical Context
This MCU implements Arm TrustZone for Armv8-M to isolate secure and non-secure execution environments, with dedicated secure boot ROM and immutable root-of-trust. Its system architecture includes a 48 MHz PLL clock generator, multiple low-power modes (including deep software standby with RTC wake-up), and a configurable interrupt controller supporting 96 NVIC inputs.
The peripheral set integrates USB 2.0 FS PHY, 4-channel 16-bit PWM timers, 2x I²C (with SMBus support), 3x SPI, 4x UART/SCI, and a 12-bit SAR ADC with hardware averaging and window comparison - all accessible via the Renesas Synergy Software Package (SSP) with certified middleware stacks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS1JA782A01CFJ#AA0 | Same S1JA family, but 512 KB Flash, 128 KB SRAM, no USB PHY - lacks integrated USB physical layer and half memory capacity. | Suitable for cost-sensitive sensor nodes without USB connectivity or smaller firmware footprints. | Select when USB device functionality is unnecessary and BOM cost reduction is prioritized over field-upgrade flexibility. |
| R7FA6M2AF3CFP#AA0 | RA6M2 series (Cortex-M4F), 1 MB Flash, 256 KB SRAM, USB HS host/device, FPU - higher performance, floating-point unit, and USB host capability. | Better suited for complex motor control or audio processing where DSP math or USB host peripherals (e.g., flash drives) are required. | Choose when application demands floating-point computation, USB host support, or higher clock speed (>48 MHz), accepting larger footprint and power budget. |
Compared with R7FS1JA782A01CFJ#AA0, the R7FS1JA783A01CFJ#AA0 adds USB device PHY and doubles memory - enabling secure OTA and richer HMI.
