Product details
Overview
R5F52306ADND#20 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 (IEEE 754 single-precision), and hardware encryption (TSIP-Lite AES-128/256). It supports USB 2.0 full-speed host/function/OTG, CAN, 24-channel 12-bit ADC (0.83 µs conversion), dual 12-bit DAC, RTC with battery backup, and capacitive touch sensing - deployed in industrial HMI and smart sensor edge nodes.
For engineers reviewing the R5F52306ADND#20 datasheet, R5F52306ADND#20 pinout, R5F52306ADND#20 application, or R5F52306ADND#20 equivalent, key selection considerations include its 64-pin HWQFN (PWQN0064KC-A) package, absence of SDHI and CAN modules (per Table 1.3), D-version temperature range (−40 to +85°C), and support for ELC-triggered peripheral coordination without CPU wake-up.
Technical Context
The R5F52306ADND#20 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and MPU-enforced memory protection. Its clock system integrates PLL, USB-dedicated PLL (48 MHz), sub-clock oscillator (32.768 kHz), and CAC for frequency accuracy validation.
Peripheral coordination is managed via Event Link Controller (ELC), enabling direct event-driven activation of timers (MTU2a/TPU), ADC, and communication interfaces - reducing interrupt latency and CPU load during low-power operation in sleep/deep-sleep modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52316ADND#U0 | Same package (PWQN0064KC-A), 256 KB flash, 32 KB RAM, but adds SDHI interface and RTC calendar mode | Required for SD card-based data storage or battery-backed calendar timestamping | Select when SD host or enhanced RTC functionality is needed; otherwise R5F52306ADND#20 offers identical core/peripheral set at lower cost |
| R5F52305ADND#U0 | Same package, 128 KB flash, 32 KB RAM, same peripheral set minus data flash (0 KB vs 8 KB) | Suitable for simpler firmware with no field-updatable parameter storage requirement | Choose for cost-sensitive designs where 8 KB data flash persistence is unnecessary; retains all timing, USB, and analog capabilities |
Compared with R5F52306ADND#20, R5F52316ADND#U0 adds SDHI and extended RTC features at higher BOM cost, while R5F52305ADND#U0 removes data flash to reduce price - both retain identical CPU performance, USB/CAN/ADC/DAC specs, and 64-pin HWQFN footprint.

FAQ
What is the maximum operating frequency and CPU performance of the R5F52306ADND#20?
The R5F52306ADND#20 operates at a maximum frequency of 54 MHz and delivers 88.56 DMIPS. Its RXv2 core includes a 32-bit hardware multiplier, IEEE 754-compliant floating-point unit, and 5-stage pipeline - enabling deterministic real-time execution for motor control and signal processing tasks within the R5F52306ADND#20's 256 KB flash and 32 KB SRAM constraints.
Does the R5F52306ADND#20 support CAN or SD host interface?
No, the R5F52306ADND#20 does not include CAN or SD host interface (SDHI) modules. Per Renesas' R01DS0261EJ0120 Table 1.3, this part belongs to the RX230 Group and explicitly lists "Not available" for both CAN and SDHI. For CAN capability, consider R5F52318ADND#U0; for SDHI, R5F52316ADND#U0 is functionally matched except for added SDHI.
What package type and pin count does the R5F52306ADND#20 use?
The R5F52306ADND#20 uses the PWQN0064KC-A package: a 64-pin HWQFN with 9×9 mm body size, 0.5 mm pitch, and exposed thermal pad. This package is confirmed in Table 1.3 of the datasheet and supports the full I/O and peripheral mapping defined for the RX230 Group's 64-pin variants, including 43 general-purpose I/O pins and dedicated USB/ADC/DAC pins.
What are the memory resources available on the R5F52306ADND#20?
The R5F52306ADND#20 integrates 256 KB of on-chip flash memory (with no-wait access up to 32 MHz), 32 KB of SRAM (no-wait at 54 MHz), and 8 KB of data flash rated for 1,000,000 program/erase cycles. The data flash supports background operation (BGO), allowing concurrent code execution and non-volatile parameter storage - a key capability retained in the R5F52306ADND#20 unlike the 128 KB variant R5F52305ADND#U0.
Is the R5F52306ADND#20 suitable for applications requiring cryptographic security?
Yes, the R5F52306ADND#20 includes TSIP-Lite - Renesas' Trusted Secure IP module - supporting AES-128 and AES-256 encryption (ECB, CBC, GCM), CMAC, XTS, and true random number generation. Key management is hardware-protected, preventing unauthorized access to the encryption engine. This makes the R5F52306ADND#20 appropriate for secure boot, firmware authentication, and encrypted sensor data transmission.
