Overview
R5F52306ADLA#20 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 256 KB on-chip flash memory, 32 KB SRAM, and 8 KB data flash. It integrates a single-precision IEEE754 FPU, 12-bit 24-channel ADC (0.83 µs conversion), dual 12-bit DAC channels, capacitive touch sensing unit (24-key support), USB 2.0 full-speed host/function/OTG, and CAN interface - deployed in industrial HMI and smart sensor nodes requiring deterministic real-time control and secure firmware execution.
For engineers reviewing the R5F52306ADLA#20 datasheet, R5F52306ADLA#20 pinout, R5F52306ADLA#20 application, or R5F52306ADLA#20 equivalent, this page delivers verified technical context, package-specific peripheral mapping, functional alternatives, and supply-ready procurement details - all grounded in Renesas R01DS0261EJ0120 Rev.1.20 documentation for the RX230 Group.
Technical Context
The R5F52306ADLA#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling 88.56 DMIPS at 54 MHz. It supports little- or big-endian data arrangement and includes an on-chip memory protection unit (MPU) and FINE debugging interface.
Its clock system combines main (1–20 MHz), sub-clock (32.768 kHz), and on-chip oscillators with PLL and USB-dedicated PLL to generate 54 MHz ICLK and 48 MHz USB clock. The device operates across 1.8–5.5 V and supports −40 to +85°C (D version), with three low-power modes and RTC operation on battery backup.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52316ADLA#20 | Same RX230 Group, 256 KB flash, 32 KB RAM, but adds SD host interface (SDHI) and RTC support | Required for systems needing local SD card logging or calendar-based scheduling | Select when SD storage or precise RTC functionality is mandatory; otherwise R5F52306ADLA#20 offers identical core performance at lower cost |
| R5F52305ADLA#20 | Same package and core, but reduced to 128 KB flash and no data flash; lacks USB and CAN modules | Suitable only for simpler control tasks without connectivity or secure firmware updates | Choose only for cost-sensitive, non-connected applications where 128 KB flash suffices and USB/CAN are unnecessary |
Compared with R5F52306ADLA#20, R5F52316ADLA#20 adds SDHI and RTC at identical flash/RAM size, while R5F52305ADLA#20 removes USB/CAN and cuts flash in half - making R5F52306ADLA#20 the optimal balance of connectivity, security, and memory for mid-tier industrial controllers.
