Renesas R5F52305ADFM#10

Overview

R5F52305ADFM#10 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 128 KB on-chip flash, 32 KB SRAM, and integrated 12-bit A/D converter with 24 channels. It supports USB 2.0 full-speed device mode, CAN interface compliant with ISO11898-1, and operates across −40 to +85°C in industrial control panels requiring deterministic real-time response.

For engineers reviewing the R5F52305ADFM#10 datasheet, R5F52305ADFM#10 pinout, R5F52305ADFM#10 application, or R5F52305ADFM#10 equivalent, key selection criteria include its 64-pin LFQFP package, absence of SDHI and CAN in this variant, presence of TSIP-Lite encryption, and compatibility with IEC60730 safety-critical firmware validation workflows.

Technical Context

The R5F52305ADFM#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE 754-compliant 32-bit FPU. It integrates a memory protection unit (MPU), on-chip debugging circuit, and event link controller (ELC) enabling interrupt-free peripheral coordination during CPU sleep.

Its clock system includes main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL input range (4–12.5 MHz), and USB-dedicated PLL for 48 MHz operation. Power management supports three low-power modes, LPT timer during software standby, and voltage detection circuits with configurable thresholds.

FAQ

What is the maximum operating frequency and core type of the R5F52305ADFM#10?

The R5F52305ADFM#10 features a 32-bit RXv2 CPU core with a maximum operating frequency of 54 MHz, delivering 88.56 DMIPS performance. Its Harvard architecture with 5-stage pipeline and variable-length instruction set enables efficient code density and deterministic real-time execution critical for industrial control applications.

Does the R5F52305ADFM#10 include CAN or SD host interface functionality?

No, the R5F52305ADFM#10 does not include CAN or SD host interface (SDHI) functionality. Per Table 1.2 in the datasheet, these modules are explicitly marked "Not supported" for the 64-pin LFQFP package variant. This distinguishes it from higher-pin-count RX231 variants like R5F52315ADFM#30 which do integrate both peripherals.

What memory resources are integrated into the R5F52305ADFM#10?

The R5F52305ADFM#10 integrates 128 KB of on-chip flash memory, 32 KB of SRAM with zero-wait-state access at 54 MHz, and no on-chip E2 DataFlash. Its memory map supports single-chip operation and includes MPU for secure memory partitioning-essential for IEC60730-certified firmware deployments.

Which package type and pin count does the R5F52305ADFM#10 use?

The R5F52305ADFM#10 uses the PLQP0064KB-C package: a 64-pin Low-Profile Quad Flat Package measuring 10 × 10 mm with 0.5 mm pitch. This RoHS-compliant, lead-free package is optimized for automated assembly and thermal performance in space-constrained industrial enclosures.

Is the R5F52305ADFM#10 qualified for extended temperature operation?

Yes, the R5F52305ADFM#10 is rated for operation from −40 to +85°C (D version). It is not rated for the extended −40 to +105°C (G version) range. This qualification aligns with industrial-grade environmental requirements for control panels, energy meters, and factory automation equipment deployed in uncontrolled ambient conditions.
