Product details
Overview
R5F52317ADND#U0 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), and USB 2.0 full-speed host/function/OTG interface - deployed in industrial HMI and smart sensor nodes requiring deterministic real-time control and secure firmware updates.
For engineers reviewing the R5F52317ADND#U0 datasheet, R5F52317ADND#U0 pinout, R5F52317ADND#U0 application, or R5F52317ADND#U0 equivalent, this page delivers verified package mapping (PWQN0064KC-A, 64-pin HWQFN, 9 × 9 mm), confirmed peripheral set (CAN not supported, SDHI not supported, RTC supported), validated clock tree (54 MHz system clock, 48 MHz USB clock), and exact functional boundaries per RX231 Group specification.
Technical Context
The R5F52317ADND#U0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, delivering 88.56 DMIPS at 54 MHz while supporting IEEE 754-compliant single-precision floating-point operations and 32-bit multiply-accumulate DSP instructions. Its memory subsystem includes no-wait 54 MHz SRAM access and flash accelerator-assisted execution above 32 MHz.
Peripherals are orchestrated via the Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention - critical for low-latency sensor acquisition and PWM waveform synchronization. The MCU integrates TSIP-Lite encryption engine with AES-128/256, true random number generation, and key protection, targeting IEC 60730 Class B compliance in safety-critical embedded systems.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52318ADND#U0 | 512 KB flash, 64 KB SRAM, same package and peripheral set; adds SDHI and CAN support not present in R5F52317ADND#U0 | Suitable where larger code footprint or SD card logging and CAN bus integration are required | Select when firmware size exceeds 384 KB or CAN/SDHI interfaces are mandatory; otherwise R5F52317ADND#U0 offers optimal cost/performance balance |
| R5F52317ADFM#30 | Same flash/SRAM specs but in PLQP0064KB-C (10 × 10 mm LFQFP); lacks exposed thermal pad and has higher thermal resistance | Better suited for through-hole assembly or legacy PCB layouts requiring QFP footprint | Choose for compatibility with existing 64-pin QFP designs; R5F52317ADND#U0 preferred for compact, thermally demanding surface-mount applications |
Compared with R5F52318ADND#U0, the R5F52317ADND#U0 reduces flash capacity by 128 KB and omits SDHI/CAN - lowering cost and power while retaining identical USB, CTSU, and FPU capabilities. Against R5F52317ADFM#30, it trades QFP manufacturability for superior thermal performance and smaller board area in HWQFN packaging.

FAQ
What is the maximum system clock frequency supported by the R5F52317ADND#U0?
The R5F52317ADND#U0 supports a maximum system clock (ICLK) frequency of 54 MHz, achieved via its on-chip PLL circuit with 4–12.5 MHz input range. This enables 88.56 DMIPS performance and no-wait-state execution for SRAM, while flash access requires one wait state above 32 MHz unless accelerated by the ROM accelerator. The R5F52317ADND#U0 maintains full peripheral functionality at this speed, including USB 48 MHz clock derivation.
Does the R5F52317ADND#U0 include CAN or SD host interface functionality?
No, the R5F52317ADND#U0 does not include CAN or SD host interface (SDHI) modules. Per Table 1.2 in the official datasheet, these peripherals are explicitly marked as "Not supported" for all 64-pin and 48-pin RX231 Group packages, including the PWQN0064KC-A variant used by R5F52317ADND#U0. These features are only available in 100-pin variants such as R5F52318ADLA#20. The R5F52317ADND#U0 retains USB 2.0, SCI, I²C, RSPI, and CTSU.
What package type and dimensions does the R5F52317ADND#U0 use?
The R5F52317ADND#U0 uses the PWQN0064KC-A package: a 64-pin HWQFN (Heat Sink Wettable Flank Quad Flat No-lead) with 9 × 9 mm body size, 0.5 mm pin pitch, and an exposed thermal pad. It is RoHS-compliant and rated for −40 to +85°C operation. This package provides superior thermal dissipation and smaller PCB footprint compared to equivalent 64-pin LFQFP alternatives like R5F52317ADFM#30.
How many channels does the 12-bit A/D converter support on the R5F52317ADND#U0?
The R5F52317ADND#U0 integrates the S12ADE 12-bit A/D converter with 24 input channels, matching the full channel count specified for RX231 Group devices in 100-pin and 64-pin packages. Each channel supports programmable sampling time, and conversion can be triggered by software, timers (MTU/TPU), external signals, or the Event Link Controller - all confirmed in Section 1.1 and Table 1.2 of the R01DS0261EJ0120 datasheet for R5F52317ADND#U0.
Is the R5F52317ADND#U0 compatible with Renesas' E2 studio and CS+ development environments?
Yes, the R5F52317ADND#U0 is fully supported by Renesas' E2 studio IDE and CS+ integrated development environment, including debug via FINE interface, flash programming, and peripheral configuration tools. Both environments provide device-specific drivers, example projects, and RXv2 core debugging features - verified in Renesas' official toolchain release notes and the RX231 Group User's Manual (R01UH0554EJ0100).
