Product details
Overview
R5F52305AGNE#20 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) with integrated FPU, 12-bit A/D converter (24 channels), and USB 2.0 full-speed host/function/OTG interface - deployed in industrial HMI and consumer appliance control systems requiring real-time responsiveness and secure firmware execution.
For engineers reviewing the R5F52305AGNE#20 datasheet, R5F52305AGNE#20 pinout, R5F52305AGNE#20 application, or R5F52305AGNE#20 equivalent, this device delivers deterministic real-time performance via ELC-triggered peripheral coordination, IEEE 754-compliant floating-point math, IEC60730 self-test support, and hardware-accelerated AES-128/256 encryption through TSIP-Lite - critical for functional safety and secure boot validation.
Technical Context
The R5F52305AGNE#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling single-cycle execution for most operations and 88.56 DMIPS at 54 MHz. It integrates a 32-bit multiplier, 32-bit divider (2-cycle min), barrel shifter, and memory protection unit (MPU) for deterministic embedded execution.
Its clock system supports multiple sources: main oscillator (1–20 MHz), sub-clock (32.768 kHz), on-chip high-/low-speed oscillators, PLL (4–12.5 MHz input), and USB-dedicated PLL - allowing independent configuration of ICLK (54 MHz), PCLKA/B/D (up to 54/32/54 MHz), BCLK (32 MHz), and FCLK (32 MHz) for precise peripheral timing control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52315ADFL#30 | Same RX230 Group, D-version (−40 to +85°C), 128 KB flash, 32 KB RAM, but includes SDHI and CAN - larger footprint (48-pin LFQFP vs. HWQFN). | Required where SD card logging or CAN bus interfacing is mandatory; not pin-compatible due to different package and pin assignment. | Select when SDHI or CAN functionality is needed and thermal constraints allow LFQFP packaging. |
| R5F52306ADFL#30 | Same package (PLQP0048KB-B), same temperature grade (G), but 256 KB flash, 32 KB RAM, no SDHI/CAN - identical pinout and peripheral subset. | Used where larger firmware image size is required without adding SD/CAN complexity; direct PCB reuse possible with minor layout adjustments for flash programming signals. | Choose for firmware scalability headroom while retaining identical mechanical fit and thermal profile. |
Compared with R5F52305AGNE#20, R5F52315ADFL#30 adds SDHI/CAN at the cost of temperature rating and package type, while R5F52306ADFL#30 offers double flash capacity in the same 48-pin LFQFP form factor - making it the only option enabling drop-in firmware expansion without board redesign.
