Product details
Overview
R5F52317ADFM#50 from Renesas is a 32-bit RXv2 microcontroller with 384 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 54 MHz (88.56 DMIPS) with integrated FPU, 12-bit A/D converter (24 channels), 12-bit D/A converter (2 channels), and capacitive touch sensing unit (24 channels). It targets industrial HMI, sensor nodes, and embedded control systems requiring real-time performance, low-power operation, and secure firmware execution.
For engineers reviewing the R5F52317ADFM#50 datasheet, R5F52317ADFM#50 pinout, R5F52317ADFM#50 application, or R5F52317ADFM#50 equivalent, this MCU delivers deterministic real-time response via ELC event linking, hardware-accelerated AES encryption (TSIP-Lite), USB 2.0 full-speed device/OTG support, and IEC60730-compliant self-test functions for safety-critical firmware deployment.
Technical Context
The R5F52317ADFM#50 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle instruction execution at 54 MHz. Its memory subsystem includes no-wait SRAM access, ROM accelerator-assisted flash execution, and background operation (BGO) for data flash programming without CPU stall.
Peripheral integration centers on deterministic timing: ELC enables interrupt-free inter-module triggering (e.g., MTU timer start → A/D conversion), while the MPU enforces memory protection for secure RTOS partitioning. The TSIP-Lite engine supports AES-128/256 in GCM/CBC modes with true random number generation and key protection against physical tampering.

It supports isochronous transfers, BC1.2 battery charging detection, and internal USB power regulation-allowing operation without external VCC_USB supply when VCC is 4.0–5.5 V. The R5F52317ADFM#50 does not include CAN or SD host interfaces, distinguishing it from higher-variant members of the RX231 family.
What security features are implemented in the R5F52317ADFM#50 for firmware protection?
The R5F52317ADFM#50 incorporates TSIP-Lite (Trusted Secure IP), providing AES-128/256 encryption in GCM, CBC, ECB, and other modes, a true random number generator, and hardware-enforced key protection against physical extraction.

The R5F52317ADFM#50 includes a 12-bit A/D converter (S12ADE) with 24 input channels and a minimum conversion time of 0.83 µs at 54 MHz ADCLK, plus a 12-bit D/A converter (R12DAA) with two independent output channels delivering 0.4–AVCC0−0.5 V. Both converters support self-diagnostic functions and are accessible via ELC-triggered operation, enabling precise, low-latency analog signal acquisition and generation within the R5F52317ADFM#50.
What low-power modes and real-time clock capabilities does the R5F52317ADFM#50 offer?
The R5F52317ADFM#50 supports three low-power modes-sleep, deep sleep, and software standby-with the low-power timer (LPT) continuing operation during software standby using the 32.768 kHz sub-clock or IWDT oscillator.
