Overview
R5F52315CGFL#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 128 KB on-chip flash, 32 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, 24-channel 12-bit A/D, dual 12-bit D/A, RTC, capacitive touch sensing (24 keys), and operates from 1.8–5.5 V across −40 to +105°C.
For engineers reviewing the R5F52315CGFL#30 datasheet, R5F52315CGFL#30 pinout, R5F52315CGFL#30 application, or R5F52315CGFL#30 equivalent, key selection criteria include its G-grade industrial temperature rating, 48-pin LFQFP package with 5-V-tolerant I/O, USB+CAN+SDHI integration, and TSIP-Lite security for embedded control in harsh environments.
Technical Context
The R5F52315CGFL#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, default speed mode), and ELC-driven event-triggered operation enabling low-power module coordination without CPU intervention - critical for deterministic real-time response in battery-backed or energy-constrained systems.

FAQ
What is the maximum operating frequency and temperature grade of the R5F52315CGFL#30?
The R5F52315CGFL#30 operates at a maximum system clock frequency of 54 MHz and is rated for industrial temperature range of −40 to +105°C (G-grade). Its USB clock is independently generated at 48 MHz via a dedicated PLL, ensuring full-speed USB 2.0 compliance without compromising system clock stability. This thermal specification makes R5F52315CGFL#30 suitable for under-hood automotive auxiliary modules and transformer-mounted utility equipment.
Does the R5F52315CGFL#30 support both USB host and device modes?
Yes, the R5F52315CGFL#30 integrates a USB 2.0 host/function/OTG module supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) operation. It implements both USB device controller (UDC) and transceiver on-die, enabling direct connection to USB peripherals or hosts without external PHY. The R5F52315CGFL#30 also supports BC1.2 battery charging detection and isochronous transfers - essential for real-time audio or sensor streaming applications.
What security features does the R5F52315CGFL#30 provide for firmware protection?
The R5F52315CGFL#30 includes TSIP-Lite - a hardware-trusted secure IP block supporting AES-128/256 encryption (GCM, ECB, CBC), CMAC authentication, true random number generation, and secure key management. Unauthorized access to the encryption engine is disabled at silicon level, preventing side-channel attacks and firmware extraction. These capabilities make R5F52315CGFL#30 compliant with IEC 62443 and suitable for secure boot and OTA update implementations.
How many analog-to-digital and digital-to-analog channels does the R5F52315CGFL#30 have?
The R5F52315CGFL#30 integrates a 12-bit successive-approximation A/D converter with 24 input channels and a minimum conversion time of 0.83 µs at 54 MHz ADCLK. It also includes two independent 12-bit D/A converter channels with output voltage range of 0.4 V to AVCC0 − 0.5 V. Both peripherals support hardware self-diagnostic functions and are accessible via the Event Link Controller for synchronized triggering - critical for closed-loop control systems using R5F52315CGFL#30.
Is the R5F52315CGFL#30 pin-compatible with other members of the RX231 Group?
The R5F52315CGFL#30 uses the PLQP0048KB-B 48-pin LFQFP package and shares identical pinout with other RX231 Group devices in the same package variant (e.g., R5F52315ADFL#30, R5F52316ADFL#30). However, peripheral enablement differs: R5F52315CGFL#30 enables CAN and SDHI, while R5F52316ADFL#30 enables SDHI but disables CAN. Thus, PCB layout is reusable, but firmware must validate module availability per part number before initialization.
