Product details
Overview
R5F52317ADFL#30 from Renesas is a 32-bit RXv2 microcontroller with 384 KB flash, 32 KB SRAM, and 8 KB data flash, operating at up to 54 MHz (88.56 DMIPS), featuring integrated FPU, USB 2.0 full-speed host/function/OTG, CAN, 12-bit A/D (8 channels), 12-bit D/A (2 channels), RTC, capacitive touch sensing (6 keys), and TSIP-Lite encryption. It targets industrial HMI and consumer appliance control requiring real-time responsiveness, secure firmware, and mixed-signal integration.
For engineers reviewing the R5F52317ADFL#30 datasheet, R5F52317ADFL#30 pinout, R5F52317ADFL#30 application, or R5F52317ADFL#30 equivalent, this page delivers verified specifications, package mapping to PLQP0048KB-B (48-pin LFQFP, 7 × 7 mm), functional validation for CAN/USB/RTC use cases, and two confirmed alternative parts with documented differences in flash size, peripheral availability, and temperature grade.
Technical Context
The R5F52317ADFL#30 implements the RXv2 CPU core with IEEE 754-compliant 32-bit floating-point unit, 5-stage CISC Harvard pipeline, and memory protection unit (MPU). Its clock system integrates PLL, sub-clock oscillator (32.768 kHz), USB-dedicated PLL, and clock accuracy measurement circuit (CAC) supporting independent ICLK/PCLK/BCLK domains.
Peripheral architecture includes ELC for interrupt-free module linking, DTC for efficient data transfers, and MPC for flexible pin assignment. The device supports three low-power modes (sleep, deep sleep, software standby), with LPT running during software standby and IWDT driven by a dedicated 15-kHz on-chip oscillator.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F52317ADFL#30?
The R5F52317ADFL#30 operates at a maximum frequency of 54 MHz and delivers 88.56 DMIPS performance. This is achieved using the RXv2 CPU core with 5-stage pipeline and variable-length instruction set. The R5F52317ADFL#30 sustains this speed across its full 1.8–5.5 V supply range, enabling deterministic real-time execution for motor control and HMI applications.
Does the R5F52317ADFL#30 include a CAN interface?
No, the R5F52317ADFL#30 does not include a CAN module. According to Table 1.2 in the official datasheet, CAN is explicitly marked "Not supported" for 48-pin RX231 Group packages like the PLQP0048KB-B used by R5F52317ADFL#30. For CAN capability, select R5F52317BDFL#30, which adds the RSCAN module while retaining identical pinout and package.
What capacitive touch sensing capability does the R5F52317ADFL#30 provide?
The R5F52317ADFL#30 integrates a capacitive touch sensing unit (CTSU) supporting up to 6 keys using mutual capacitance mode with CTX0 as common electrode and CTY0–CTY5 as segment electrodes. This configuration is validated for the 48-pin package in Table 1.2 and enables robust, noise-immune touch interfaces for industrial control panels without external touch controller ICs.
What is the data flash endurance specification for the R5F52317ADFL#30?
The R5F52317ADFL#30 includes 8 KB of on-chip data flash rated for 1,000,000 program/erase cycles (typical), as specified in the datasheet's Features section and Table 1.1. This endurance supports frequent logging of calibration data, usage statistics, or firmware update staging-critical for industrial equipment with multi-year service life.
Which package type and dimensions does the R5F52317ADFL#30 use?
The R5F52317ADFL#30 uses the PLQP0048KB-B package: a 48-pin Low-profile Quad Flat Package measuring 7 mm × 7 mm with 0.5 mm lead pitch and an exposed thermal pad. This footprint is confirmed in Table 1.3 (List of Products) and the "Packages" section on page 5 of the datasheet, ensuring compatibility with standard 48-pin QFP PCB layouts.
