Renesas R5F52306ADFL#10

Overview

R5F52306ADFL#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 8 KB data flash. It integrates a single-precision IEEE 754 FPU, 12-bit 24-channel ADC (0.83 µs conversion), two 12-bit DAC channels, capacitive touch sensing unit (24-key self-capacitance), and USB 2.0 full-speed host/function/OTG support - deployed in industrial HMI control panels requiring real-time responsiveness and secure firmware execution.

For engineers reviewing the R5F52306ADFL#10 datasheet, R5F52306ADFL#10 pinout, R5F52306ADFL#10 application, or R5F52306ADFL#10 equivalent, key selection criteria include its 48-pin LFQFP package (7 × 7 mm, 0.5 mm pitch), −40 to +85°C temperature grade, absence of CAN and SDHI peripherals (per Table 1.3), and TSIP-Lite encryption engine for secure boot and key management.

Technical Context

The R5F52306ADFL#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - delivering 88.56 DMIPS at 54 MHz. It supports little-endian or big-endian data arrangement and includes an on-chip 32-bit multiplier, 32-bit divider (2-cycle min), barrel shifter, and memory protection unit (MPU).

Its clock system features main (1–20 MHz), sub-clock (32.768 kHz), and on-chip high-/low-speed oscillators, plus PLL and USB-dedicated PLL. System clock (ICLK) runs up to 54 MHz; peripheral clocks (PCLKA/B/D) are independently configurable - PCLKA for MTU2a (54 MHz), PCLKD for S12AD (54 MHz), PCLKB for most peripherals (32 MHz).

FAQ

What is the maximum operating frequency and CPU performance of the R5F52306ADFL#10?

The R5F52306ADFL#10 operates at a maximum system clock frequency of 54 MHz using its RXv2 CPU core, achieving 88.56 DMIPS. Its architecture includes a 5-stage pipeline, variable-length instructions, and hardware floating-point unit compliant with IEEE 754 - enabling deterministic real-time execution for control and signal processing tasks within the R5F52306ADFL#10's 256 KB flash constraint.

Does the R5F52306ADFL#10 support CAN or SD host interface?

No, the R5F52306ADFL#10 does not include CAN or SD host interface (SDHI) peripherals. As confirmed in Table 1.3 of the datasheet, this part is marked "Not available" for both CAN and SDHI functions. These modules are present only in higher-pin-count variants like the RX231 Group (e.g., R5F52316ADFL#30), making the R5F52306ADFL#10 suitable for applications where those interfaces are unnecessary.

What package type and pin count does the R5F52306ADFL#10 use?

The R5F52306ADFL#10 uses the PLQP0048KB-B package: a 48-pin Low-Profile Quad Flat Package measuring 7 mm × 7 mm with 0.5 mm lead pitch. This compact, surface-mount package supports 34 general-purpose I/O pins, 24 ADC inputs, and dedicated USB/oscillator pins - verified in Table 1.2 and page 5 of the R01DS0261EJ0120 datasheet for the RX230 Group.

What security features are integrated into the R5F52306ADFL#10?

The R5F52306ADFL#10 integrates TSIP-Lite - Renesas' Trusted Secure IP engine - supporting AES-128/256 encryption in GCM, CBC, and ECB modes, along with a true random number generator and secure key management. These features enable hardware-accelerated secure boot, firmware authentication, and encrypted data storage - all implemented within the R5F52306ADFL#10 die without external security IC dependency.

What is the operating temperature range and voltage supply specification for the R5F52306ADFL#10?

The R5F52306ADFL#10 is rated for industrial operation from −40°C to +85°C (D version) and accepts a single supply voltage from 1.8 V to 5.5 V. Its power architecture supports dynamic voltage/frequency scaling: 8 MHz at 1.8–2.4 V, 16 MHz at 2.4–2.7 V, and full 54 MHz operation above 2.7 V - ensuring reliable R5F52306ADFL#10 performance across diverse power rail conditions in embedded systems.
