Product details
Overview
R5F52318ADND#00 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 512 KB on-chip flash, 64 KB SRAM, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, CAN, SD host interface, capacitive touch sensing (24 channels), 12-bit A/D (24 ch), 12-bit D/A (2 ch), RTC, FPU, and TSIP-Lite encryption. It targets industrial HMI and embedded control systems requiring secure, low-power, mixed-signal processing.
For engineers reviewing the R5F52318ADND#00 datasheet, R5F52318ADND#00 pinout, R5F52318ADND#00 application, or R5F52318ADND#00 equivalent, key selection criteria include USB/CAN coexistence, 54 MHz real-time performance with FPU, 24-channel capacitive touch support, and 64-pin HWQFN (9 × 9 mm) packaging for space-constrained designs.
Technical Context
The R5F52318ADND#00 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling 88.56 DMIPS at 54 MHz. It includes a single-precision IEEE 754 FPU, 32-bit multiply-accumulate, and hardware divider with two-cycle minimum execution.
Its peripheral set is optimized for deterministic real-time control: ELC enables interrupt-free inter-module triggering (e.g., timer-triggered ADC conversion), while MTU2a and TPU provide 16-bit PWM, input capture, and phase counting across six channels each-supporting motor control and encoder interfacing without CPU intervention.

FAQ
What is the maximum operating frequency of the R5F52318ADND#00?
The R5F52318ADND#00 operates at a maximum system clock frequency of 54 MHz, delivering 88.56 DMIPS performance. This speed is achievable across its full 1.8–5.5 V supply range, with no wait states on SRAM and accelerated flash access via ROM accelerator hit logic. The USB clock is independently generated at 48 MHz using the dedicated USB PLL circuit inside the R5F52318ADND#00.
Does the R5F52318ADND#00 support USB device and host functionality?
Yes, the R5F52318ADND#00 integrates a full-featured USB 2.0 module supporting host, function, and On-The-Go (OTG) modes at full-speed (12 Mbps) and low-speed (1.5 Mbps). It includes an internal transceiver and USB voltage regulator, allowing operation without external VCC_USB supply when VCC is between 4.0 V and 5.5 V-reducing external component count in designs using the R5F52318ADND#00.
What type of package does the R5F52318ADND#00 use?
The R5F52318ADND#00 uses the PWQN0064KC-A package: a 64-pin wettable flank QFN measuring 9 × 9 mm with 0.5 mm pitch and an exposed thermal pad. This RoHS-compliant package supports automated optical inspection (AOI) and offers superior thermal performance compared to standard QFN variants-critical for sustained 54 MHz operation in the R5F52318ADND#00.
How many analog-to-digital converter channels does the R5F52318ADND#00 have?
The R5F52318ADND#00 integrates the S12ADE 12-bit A/D converter with 24 input channels. Each channel supports programmable sampling time, and conversion can be triggered by software, timers (MTU/TPU), external signals, or the Event Link Controller (ELC). Minimum conversion time is 0.83 µs per channel when ADCLK runs at 54 MHz-enabling high-fidelity sensor acquisition in the R5F52318ADND#00.
Is the R5F52318ADND#00 compatible with IEC 60730 safety standards?
The R5F52318ADND#00 includes hardware features supporting IEC 60730 compliance-including self-diagnostic functions for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), and RAM test assistance via the Data Operation Circuit (DOC). While R5F52318ADND#00 provides these capabilities, full Class B certification requires implementation of the associated software library and validation-available separately for the R5F52318ADND#00.
