Product details
Overview
R5F52305ADFL#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, 8 KB data flash, and integrated 12-bit A/D and D/A converters. It supports USB 2.0 full-speed host/function/OTG, CAN, SCI, I²C, RSPI, and capacitive touch sensing, targeting industrial HMI and sensor-edge control applications.
For engineers reviewing the R5F52305ADFL#10 datasheet, R5F52305ADFL#10 pinout, R5F52305ADFL#10 application, or R5F52305ADFL#10 equivalent, this MCU delivers deterministic real-time performance with FPU, MPU, ELC event-driven operation, and IEC60730-compliant self-test functions for safety-critical embedded systems.
Technical Context
The R5F52305ADFL#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle instruction execution at 54 MHz. It integrates a single-precision IEEE754-compliant FPU, 32-bit multiplier, and hardware divider with two-cycle minimum latency.
Its peripheral subsystem includes an Event Link Controller (ELC) enabling direct module-to-module triggering without CPU intervention, and a Multi-function Pin Controller (MPC) supporting flexible I/O function assignment across 34 GPIOs in its 48-pin LFQFP package. The device lacks SDHI and CAN modules per Table 1.2 but retains full USB 2.0 OTG support with internal VCC_USB power regulation.

The R5F52305ADFL#10 operates at a maximum system clock frequency of 54 MHz, delivering 88.56 DMIPS performance using the RXv2 32-bit CPU core. Its 5-stage pipeline, variable-length instruction set, and single-cycle execution capability enable deterministic real-time response critical for motor control and sensor processing. The R5F52305ADFL#10 achieves this performance while maintaining ultra-compact code density and low power consumption.
Does the R5F52305ADFL#10 include a real-time clock (RTC) module?
No, the R5F52305ADFL#10 does not include an RTC module. According to Table 1.2 in the datasheet, RTC is supported only in 100-pin and 64-pin RX231 packages-not in the 48-pin RX230 variants like R5F52305ADFL#10. For RTC functionality, engineers should select R5F52315ADFL#30 (same 48-pin package) or upgrade to a 64-pin RX231 part such as R5F52316ADFM#30.
What USB capabilities does the R5F52305ADFL#10 support?
The R5F52305ADFL#10 integrates a full-speed USB 2.0 host/function/OTG module compliant with USB 2.0 specification, supporting 12 Mbps transfers, isochronous mode, and BC1.2 battery charging. It includes an internal VCC_USB regulator that powers the transceiver directly from the main VCC (4.0–5.5 V), eliminating the need for an external 3.3 V USB supply. The R5F52305ADFL#10 does not require external PHY components.
Which analog peripherals are integrated into the R5F52305ADFL#10?
The R5F52305ADFL#10 integrates a 12-bit S12ADE analog-to-digital converter with 24 input channels and 0.83 µs conversion time, plus a 12-bit R12DAA digital-to-analog converter with two independent output channels (0.4–AVCC0−0.5 V range). It also includes a temperature sensor (TEMPSA) whose output is digitized by the same A/D converter, and two analog comparators (CMPBa) with window-mode capability-all accessible within the 48-pin PLQP0048KB-B footprint.
Is the R5F52305ADFL#10 qualified for industrial temperature range operation?
Yes, the R5F52305ADFL#10 is rated for industrial temperature operation from −40°C to +85°C (D version). This qualification is confirmed in Table 1.3 of the datasheet, which lists R5F52305ADFL#30 under "D Version (Ta = –40 to +85°C)" with package PLQP0048KB-B. The device meets JEDEC JESD22-A104 reliability standards for extended thermal cycling and is suitable for deployment in factory automation, building controls, and outdoor equipment.
