Product details
Overview
R5F52318ADNE#00 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 512 KB on-chip flash, 64 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 R5F52318ADNE#00 datasheet, R5F52318ADNE#00 pinout, R5F52318ADNE#00 application, or R5F52318ADNE#00 equivalent, this MCU delivers deterministic real-time control with low-power modes (deep sleep, software standby), event-driven peripheral coordination via ELC, and IEC60730-compliant self-test functions for industrial HMI, smart sensors, and USB-connected embedded systems.
Technical Context
The R5F52318ADNE#00 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and fast interrupt response. Its memory subsystem includes no-wait 54-MHz SRAM access, flash accelerator for zero-wait execution above 32 MHz, and background operation (BGO) for 8-KB data flash programming during runtime.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables 61 event sources to trigger module actions-including A/D conversion start, timer resets, and PWM updates-without CPU intervention, while the Multi-function Pin Controller (MPC) allows flexible I/O function assignment across 48 pins in its HWQFN package.
