Product details
Overview
R5F52317ADFP#10 from Renesas is a 32-bit RXv2 microcontroller with 384 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 54 MHz (88.56 DMIPS). It integrates a single-precision IEEE 754 FPU, 24-channel 12-bit A/D converter (0.83 µs conversion), USB 2.0 full-speed host/function/OTG, CAN 2.0B (1 Mbps), and capacitive touch sensing unit supporting up to 24 keys - deployed in industrial HMI and smart sensor nodes requiring deterministic real-time control and secure firmware updates.
For engineers reviewing the R5F52317ADFP#10 datasheet, R5F52317ADFP#10 pinout, R5F52317ADFP#10 application, or R5F52317ADFP#10 equivalent, key selection considerations include its 100-pin LFQFP package (PLQP0100KB-B), −40 to +85°C temperature grade (D version), absence of SDHI and CAN modules per Table 1.3, and compatibility with Renesas' E2 studio and CS+ toolchains for IEC60730-compliant safety firmware development.
Technical Context
The R5F52317ADFP#10 belongs to the RX231 Group and implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions. It supports little-endian data arrangement, 32-bit × 32-bit multiply-accumulate, and 32-bit divide operations completing in two clock cycles.
Its clock system includes main (1–20 MHz), sub-clock (32.768 kHz), and on-chip oscillators, with PLL enabling 54 MHz system clock and 48 MHz USB clock. The MCU features ELC for event-driven peripheral coordination without CPU intervention and MPU for memory protection - critical for deterministic real-time execution in safety-aware applications.
