Renesas R5F52316ADND#U0

Overview

R5F52316ADND#U0 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 256 KB on-chip flash memory, 32 KB SRAM, and integrated USB 2.0 full-speed host/function/OTG, CAN, capacitive touch sensing (10 channels), 12-bit A/D converter (12 channels), and TSIP-Lite encryption engine. It targets industrial HMI and consumer appliance control where low-power operation, secure firmware execution, and mixed-signal integration are required.

For engineers reviewing the R5F52316ADND#U0 datasheet, R5F52316ADND#U0 pinout, R5F52316ADND#U0 application, or R5F52316ADND#U0 equivalent, this page delivers verified specifications, package mapping to PWQN0064KC-A (9 × 9 mm HWQFN), functional pin roles, real-world use cases in appliance UIs and industrial sensors, and two validated alternative parts for design flexibility.

Technical Context

The R5F52316ADND#U0 implements the RXv2 CPU core with IEEE 754-compliant 32-bit floating-point unit, 88.56 DMIPS performance at 54 MHz, and memory protection unit (MPU) for safe embedded execution. Its clock system supports main oscillator (1–20 MHz), sub-clock (32.768 kHz), and USB-dedicated PLL (4/6/8/12 MHz), enabling independent 54 MHz system clock and 48 MHz USB clock.

Peripheral integration includes ELC for interrupt-free module linking, DTC for efficient data transfers, and CTSU supporting mutual capacitance up to 10 keys - all operating under three low-power modes (sleep, deep sleep, software standby) with RTC and LPT active during standby.
