Overview
R5F52315CDNE#20 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 128 KB on-chip flash, 32 KB SRAM, 8 KB data flash, a 12-bit 24-channel ADC (0.83 µs conversion), and dual 12-bit DAC channels. It integrates USB 2.0 full-speed host/function/OTG, CAN 2.0B (1 Mbps), SCI, I²C, RSPI, capacitive touch sensing (24 keys), RTC, TSIP-Lite encryption, and operates from 1.8–5.5 V across −40 to +85°C.
For engineers reviewing the R5F52315CDNE#20 datasheet, R5F52315CDNE#20 pinout, R5F52315CDNE#20 application, or R5F52315CDNE#20 equivalent, this MCU supports industrial HMI, battery-powered sensor nodes, USB-C peripheral control, and CAN-based embedded gateways requiring integrated security, low-power RTC, and analog signal conditioning with deterministic real-time response.
Technical Context
The R5F52315CDNE#20 belongs to the RX231 Group and implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, memory protection unit (MPU), and CISC Harvard architecture with 5-stage pipeline. It supports little- or big-endian data arrangement and executes instructions in one cycle at 54 MHz.
Its peripheral set includes ELC for interrupt-free module linking, DTC/DMAC for autonomous data transfers, and TSIP-Lite for AES-128/256 (GCM/CBC/ECB), true RNG, and key protection - all validated for IEC 60730 Class B compliance.
