Overview
R5F52315ADFP#30 from Renesas is a 32-bit RXv2 microcontroller with 128 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 54 MHz (88.56 DMIPS). It integrates a single-precision IEEE 754 FPU, 12-bit 24-channel ADC (0.83 µs conversion), dual 12-bit DACs, USB 2.0 full-speed host/function/OTG, CAN 2.0B, and capacitive touch sensing-targeting industrial HMI and embedded control applications requiring real-time responsiveness and secure firmware execution.
For engineers reviewing the R5F52315ADFP#30 datasheet, R5F52315ADFP#30 pinout, R5F52315ADFP#30 application, or R5F52315ADFP#30 equivalent, this MCU delivers deterministic real-time performance via its 5-stage pipeline CISC Harvard architecture, ELC-driven event-triggered peripheral coordination, IEC60730-compliant self-test features, and hardware-accelerated AES-128/256 encryption through TSIP-Lite.
Technical Context
The R5F52315ADFP#30 implements the RXv2 CPU core with 32-bit multiply-accumulate, 32-bit divider (2-cycle min), and fast interrupt response. Its clock system supports independent domain clocks: ICLK at 54 MHz for CPU, PCLKA at 54 MHz for MTU2a, PCLKD at 54 MHz for ADC, and BCLK at 32 MHz for external bus interface.
Peripheral integration includes ELC for interrupt-free module linking, DTC for efficient data movement, MPC for flexible pin assignment, and TSIP-Lite for key-protected AES-GCM/ECB/CBC operations. The device supports software standby mode with active low-power timer (LPT) and RTC powered by sub-clock oscillator (32.768 kHz).
