Product details
Overview
R5F52306ADFP#10 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 256 KB on-chip flash memory, 32 KB SRAM, and integrated 12-bit A/D converter (24 channels), 12-bit D/A converter (2 channels), USB 2.0 full-speed host/function/OTG, CAN interface, capacitive touch sensing unit (24 keys), and TSIP-Lite encryption engine. It targets industrial HMI, sensor nodes, and smart appliance control where real-time responsiveness, low-power operation, and secure firmware execution are required.
For engineers reviewing the R5F52306ADFP#10 datasheet, R5F52306ADFP#10 pinout, R5F52306ADFP#10 application, or R5F52306ADFP#10 equivalent, key selection considerations include its 100-pin LFQFP package (PLQP0100KB-B), −40 to +85°C temperature grade, absence of SDHI and CAN modules (per Table 1.3), and compatibility with Renesas' RX family toolchain and E2 studio IDE.
Technical Context
The R5F52306ADFP#10 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 88.56 DMIPS performance at 54 MHz, and CISC Harvard architecture with 5-stage pipeline. It supports little- or big-endian data arrangement and includes memory protection unit (MPU) for safe embedded execution.
Its clock system integrates main (1–20 MHz), sub-clock (32.768 kHz), and on-chip oscillators, with PLL enabling 54 MHz system clock and 48 MHz USB clock. Power management includes three low-power modes, low-power timer (LPT), and RTC with battery backup support - all confirmed for this D-version part.
