Product details
Overview
R5F52316ADND#20 from Renesas is a 32-bit RXv2 microcontroller with 256 KB on-chip flash, 32 KB SRAM, and 54 MHz max operating frequency (88.56 DMIPS), featuring integrated FPU, 12-bit A/D converter (24 channels), 12-bit D/A converter (2 channels), USB 2.0 full-speed host/function/OTG, CAN interface, capacitive touch sensing unit (24 keys), and TSIP-Lite encryption engine - deployed in industrial HMI and smart sensor edge nodes requiring real-time control and secure connectivity.
For engineers reviewing the R5F52316ADND#20 datasheet, R5F52316ADND#20 pinout, R5F52316ADND#20 application, or R5F52316ADND#20 equivalent, this MCU delivers deterministic real-time performance via ELC-triggered peripheral coordination, low-power operation across three sleep modes, IEEE 754-compliant floating-point math, and IEC60730-ready self-test functions for safety-critical firmware updates and sensor data integrity.
Technical Context
The R5F52316ADND#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling single-cycle execution for most operations and 88.56 DMIPS at 54 MHz. It integrates a single-precision FPU compliant with IEEE 754 and a 32-bit hardware divider completing in two clock cycles.
Its peripheral set includes a 24-channel 12-bit A/D converter with 0.83 µs conversion time, dual 12-bit D/A outputs, USB 2.0 controller with internal VCC_USB power supply, one ISO11898-1-compliant CAN channel, and an Event Link Controller (ELC) that enables interrupt-free inter-module triggering - critical for deterministic timing in motor control and battery management systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52316ADFM#30 | Same core, memory, and peripherals; differs only in PLQP0064KB-C package (10 × 10 mm LFQFP vs. 9 × 9 mm HWQFN) | Requires PCB redesign due to larger footprint and different pinout; better thermal dissipation in convection-cooled enclosures | Select when mechanical mounting constraints favor QFP or hand-soldering is required. |
| R5F52315ADND#U0 | 128 KB flash, 32 KB RAM, same package; lacks data flash (0 KB vs. 8 KB) and SDHI interface | Suitable for cost-sensitive, non-data-logging applications where firmware size and secure storage are less critical | Choose when firmware footprint < 128 KB and no SD card interfacing is needed - reduces BOM cost by ~12%. |
