Product details
Overview
R5F52317ADFP#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 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.
For engineers reviewing the R5F52317ADFP#30 datasheet, R5F52317ADFP#30 pinout, R5F52317ADFP#30 application, or R5F52317ADFP#30 equivalent, key selection considerations include its 100-pin LFQFP package (PLQP0100KB-B), absence of CAN and SDHI in RX231 Group variants, support for IEC60730 safety functions, and compatibility with Renesas' e2 studio and CS+ development tools.
Technical Context
The R5F52317ADFP#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, variable-length instructions, and on-chip MPU. It integrates dual clock domains: ICLK at 54 MHz for CPU/system, PCLKA at 54 MHz for MTU2a, and PCLKD at 54 MHz for S12ADE - enabling deterministic real-time timing for motor control and industrial I/O.
Its peripheral set includes ELC for interrupt-free event-driven operation between modules (e.g., TPU triggering A/D conversion), DTC for efficient data movement without CPU intervention, and TSIP-Lite for secure key management and AES-GCM authenticated encryption - all validated for functional safety compliance per IEC60730 Class B.
