Product details
Overview
R5F52317BDFL#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 384 KB on-chip flash, 32 KB SRAM, 8 KB data flash, integrated FPU (IEEE 754 single-precision), and hardware encryption (TSIP-Lite with AES-128/256). It supports 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, and operates from 1.8–5.5 V across −40 to +85°C. Used in industrial HMI and smart appliance control systems requiring secure, real-time mixed-signal processing.
For engineers reviewing the R5F52317BDFL#30 datasheet, R5F52317BDFL#30 pinout, R5F52317BDFL#30 application, or R5F52317BDFL#30 equivalent, key selection criteria include its 48-pin LFQFP package (PLQP0048KB-B), absence of CAN and SDHI modules per package-specific configuration, presence of USB 2.0 OTG and TSIP-Lite security, and compatibility with Renesas' RX family toolchain and E2 studio IDE.
Technical Context
The R5F52317BDFL#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and fast interrupt response. Its clock system integrates PLL, USB-dedicated PLL (4/6/8/12 MHz), sub-clock oscillator (32.768 kHz), and CAC for frequency accuracy measurement.
Peripheral integration includes ELC for event-driven module triggering without CPU intervention, DTC for interrupt-triggered transfers, and MPC for flexible pin function assignment. The device lacks CAN and SDHI modules in its 48-pin LFQFP configuration, as confirmed in Table 1.2, but retains full USB 2.0 OTG, SCI (4 channels), RIIC, RSPI, SSI, and CTSU support.
