Product details
Overview
R5F52306ADFM#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, integrated FPU compliant with IEEE754, and 12-bit A/D converter with 24 channels. It targets industrial HMI, sensor nodes, and embedded control systems requiring real-time performance, low-power operation, and secure firmware execution.
For engineers reviewing the R5F52306ADFM#30 datasheet, R5F52306ADFM#30 pinout, R5F52306ADFM#30 application, or R5F52306ADFM#30 equivalent, key selection criteria include its 64-pin LFQFP package (PLQP0064KB-C), absence of CAN and SDHI modules (per Table 1.3), support for USB 2.0 full-speed host/function/OTG, and D-version temperature range (−40 to +85°C).
Technical Context
The R5F52306ADFM#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle instruction execution. It integrates memory protection unit (MPU), on-chip debugging circuit, and CISC-based DSP extensions including 32-bit MAC and 16-bit multiply-subtract operations.
Its clock system supports main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL (4–12.5 MHz input), and USB-dedicated PLL; system clock runs at 54 MHz while peripheral clocks (PCLKA/B/D) are independently configurable up to 54 MHz, 32 MHz, or 54 MHz respectively. The device lacks CAN and SDHI modules but retains USB, SCI×5, I²C, RSPI, CTSU, and dual 12-bit D/A converters per Table 1.2.
