Product details
Overview
R5F52318ADFL#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 512 KB on-chip flash, 64 KB SRAM, 8 KB data flash, integrated FPU (IEEE 754 single-precision), and hardware encryption (TSIP-Lite AES-128/256). It supports USB 2.0 full-speed host/function/OTG, CAN, SD host interface, capacitive touch sensing (6 channels), 12-bit A/D (8 channels), 12-bit D/A (2 channels), RTC, and operates from 1.8–5.5 V across −40 to +85°C.
For engineers reviewing the R5F52318ADFL#30 datasheet, R5F52318ADFL#30 pinout, R5F52318ADFL#30 application, or R5F52318ADFL#30 equivalent, key selection criteria include its 48-pin LFQFP package, CAN + USB + SDHI integration, 54-MHz real-time performance with FPU, and IEC60730-ready safety features for industrial control and embedded HMI systems.
Technical Context
The R5F52318ADFL#30 belongs to the RX231 Group and implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions. It integrates a dedicated USB-dedicated PLL (4/6/8/12 MHz), sub-clock RTC oscillator (32.768 kHz), and independent watchdog timer driven by a 15-kHz on-chip oscillator.
Its peripheral set includes one CAN channel (ISO 11898-1, up to 1 Mbps), one SD host interface (SD/SDIO 1-/4-bit bus, default speed mode), and event link controller (ELC) enabling interrupt-free inter-module triggering - critical for low-latency deterministic operation in motor control and power management.

FAQ
What is the maximum operating frequency and CPU performance of the R5F52318ADFL#30?
The R5F52318ADFL#30 operates at a maximum system clock frequency of 54 MHz, delivering 88.56 DMIPS of performance using the 32-bit RXv2 CPU core. Its Harvard architecture with 5-stage pipeline and variable-length instruction set enables efficient code density and deterministic real-time execution, validated in Renesas' R01DS0261EJ0120 datasheet.
Does the R5F52318ADFL#30 support USB 2.0 and CAN simultaneously?
Yes, the R5F52318ADFL#30 integrates both USB 2.0 full-speed host/function/OTG (12 Mbps) and a single-channel CAN module compliant with ISO 11898-1 (up to 1 Mbps). These operate independently with dedicated clock domains (USB-dedicated PLL and CAN bit-timing logic), enabling concurrent use in gateway or diagnostic applications per R01DS0261EJ0120 Section 1.1.
What are the analog capabilities of the R5F52318ADFL#30?
The R5F52318ADFL#30 includes a 12-bit S12ADE A/D converter with 8 input channels (reduced from 24 in larger packages), capable of 0.83 µs minimum conversion time at 54 MHz ADCLK, and a 12-bit R12DAA D/A converter with two output channels (0.4–AVCC0−0.5 V range). Both support self-diagnostic and disconnection detection per IEC60730 requirements.
Is the R5F52318ADFL#30 pin-compatible with other RX231 Group members?
The R5F52318ADFL#30 uses the PLQP0048KB-B 48-pin LFQFP package and shares identical pinout with other 48-pin RX231 variants like R5F52317ADFL#30 and R5F52316ADFL#30. However, it is not pin-compatible with 64-pin or 100-pin RX231 packages due to differing pin counts and peripheral mappings per Table 1.2 in R01DS0261EJ0120.
What security and functional safety features does the R5F52318ADFL#30 provide?
The R5F52318ADFL#30 includes TSIP-Lite hardware encryption (AES-128/256, GCM/CBC modes), true random number generation, memory protection unit (MPU), and IEC60730-compliant self-test functions for A/D converter, independent watchdog timer (IWDT), clock frequency accuracy measurement (CAC), and RAM testing - all documented in R01DS0261EJ0120 Sections 1.1 and 1.2.
