Product details
Overview
R5F52317ADNE#20 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz, featuring 384 KB on-chip flash, 32 KB SRAM, 8 KB data flash, integrated FPU (IEEE 754 single-precision), and 12-bit A/D converter with 24 channels - deployed in industrial HMI and sensor gateway applications requiring real-time control and secure firmware execution.
For engineers reviewing the R5F52317ADNE#20 datasheet, R5F52317ADNE#20 pinout, R5F52317ADNE#20 application, or R5F52317ADNE#20 equivalent, key selection criteria include its 48-pin HWQFN (7 × 7 mm) package, CAN-free configuration, absence of SD host interface, and support for USB 2.0 full-speed device/OTG but not host mode - critical for compact embedded designs with strict I/O and peripheral constraints.
Technical Context
The R5F52317ADNE#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, delivering 88.56 DMIPS at 54 MHz while supporting IEEE 754-compliant floating-point operations and 32-bit multiply-accumulate DSP instructions. Its memory subsystem includes no-wait access SRAM and flash accelerator-assisted ROM access above 32 MHz.
Peripherals are orchestrated via the Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention - particularly used for synchronizing A/D conversion start with MTU2 timer events or PWM edge detection. The MCU operates across 1.8–5.5 V with three low-power modes, including software standby with active low-power timer (LPT) driven by sub-clock or IWDT oscillator.

FAQ
What is the maximum operating frequency and core type of the R5F52317ADNE#20?
The R5F52317ADNE#20 features a 32-bit RXv2 CPU core with a maximum operating frequency of 54 MHz, achieving 88.56 DMIPS. It supports IEEE 754-compliant single-precision floating-point operations and 32-bit multiply-accumulate instructions - making R5F52317ADNE#20 suitable for real-time signal processing and motor control algorithms without external coprocessors.
Does the R5F52317ADNE#20 include CAN or SD host interface functionality?
No, the R5F52317ADNE#20 does not include CAN or SD host interface (SDHI) modules. Per Table 1.2 of the datasheet, these peripherals are excluded in all 48-pin RX231 variants, including R5F52317ADNE#20. This distinguishes it from 64- and 100-pin RX231 packages that support CAN and SDHI - confirming R5F52317ADNE#20 is optimized for compact, USB-centric, non-automotive applications.
What package type and dimensions does the R5F52317ADNE#20 use?
The R5F52317ADNE#20 uses the PWQN0048KB-A package: a 48-pin wettable flank QFN measuring 7 × 7 mm with 0.5 mm pitch and an exposed thermal pad. This package enables reliable automated optical inspection (AOI) and efficient heat dissipation in dense industrial PCB layouts - a key differentiator from standard QFN variants used in the R5F52317ADNE#20's pin-compatible predecessors.
How much flash, SRAM, and data flash memory does the R5F52317ADNE#20 integrate?
The R5F52317ADNE#20 integrates 384 KB of on-chip flash memory (with no-wait access up to 32 MHz), 32 KB of SRAM (no-wait at full 54 MHz), and 8 KB of data flash rated for 1,000,000 program/erase cycles. This memory configuration supports dual-bank firmware updates, real-time data logging, and cryptographic key storage - all within the R5F52317ADNE#20's single-chip footprint.
Is the R5F52317ADNE#20 qualified for extended temperature operation?
The R5F52317ADNE#20 is specified for the D temperature grade: −40 to +85°C ambient operating range. It is not rated for the G grade (−40 to +105°C). Designs requiring operation above +85°C must select alternate variants such as R5F52317AGNE#U0 - confirming R5F52317ADNE#20 targets commercial and industrial environments with controlled thermal profiles.
