Product details
Overview
R5F52306AGFL#10 from Renesas is a 32-bit RXv2 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 (IEEE 754 single-precision), and 12-bit A/D converter with 24 channels. It targets industrial control panels requiring real-time responsiveness, secure firmware updates, and capacitive touch interfaces.
For engineers reviewing the R5F52306AGFL#10 datasheet, R5F52306AGFL#10 pinout, R5F52306AGFL#10 application, or R5F52306AGFL#10 equivalent, this MCU delivers deterministic real-time performance, IEC60730-compliant self-test functions, low-power RTC operation, and hardware-accelerated AES encryption via TSIP-Lite - critical for safety-certified embedded systems.
Technical Context
The R5F52306AGFL#10 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates an on-chip FPU compliant to IEEE 754 and a 32-bit divider completing in two clock cycles.
Its peripheral set includes ELC for interrupt-free module linking, DTC for efficient data transfers, and MPC for flexible pin assignment. The device supports three low-power modes (sleep, deep sleep, software standby) with LPT active during standby and RTC powered by sub-clock oscillator.
