Product details
Overview
R5F52318BGFM#30 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 512 KB on-chip flash, 64 KB SRAM, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, CAN 2.0B (1 Mbps), 24-channel 12-bit ADC (0.83 µs conversion), dual 12-bit DAC, capacitive touch sensing (24 keys), FPU (IEEE 754 single-precision), and TSIP-Lite encryption. It targets industrial HMI, smart sensors, and embedded control requiring real-time performance and secure connectivity.
For engineers reviewing the R5F52318BGFM#30 datasheet, R5F52318BGFM#30 pinout, R5F52318BGFM#30 application, or R5F52318BGFM#30 equivalent, this MCU delivers verified 54 MHz operation with integrated USB/CAN, hardware-accelerated crypto, low-power RTC, and IEC60730-compliant self-test functions - critical for safety-aware industrial firmware development and BOM consolidation.
Technical Context
The R5F52318BGFM#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling 88.56 DMIPS at 54 MHz. It includes on-chip FPU, 32-bit multiplier, and divider with two-cycle minimum execution - supporting deterministic real-time math in motor control and sensor fusion.
Its peripheral set is coordinated via Event Link Controller (ELC), allowing timer-triggered ADC conversions, PWM synchronization, and module-to-module event chaining without CPU intervention. Clock domains are strictly segmented: ICLK (54 MHz system), PCLKA (54 MHz for MTU2), PCLKD (54 MHz for ADC), and BCLK (32 MHz for external bus), ensuring predictable timing across mixed-criticality subsystems.
