Product details
Overview
R5F51115AGFL#3A from Renesas is a 32-bit RX CPU core microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 14-channel 12-bit A/D converter, two 8-bit D/A outputs, USB 2.0 full-speed host/function/OTG, RTC, and ELC for low-power sensor node control in industrial IoT gateways.
For engineers reviewing the R5F51115AGFL#3A datasheet, R5F51115AGFL#3A pinout, R5F51115AGFL#3A application, or R5F51115AGFL#3A equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40°C to +105°C temperature grade, integrated USB transceiver with BC support, and software standby mode recovery in 4.8 μs.
Technical Context
The R5F51115AGFL#3A implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for IEC 60730 compliance.
It supports event-driven operation via the Event Link Controller (ELC), allowing peripheral modules-including MTU2 timers, A/D converter, and RSPI-to trigger each other without CPU intervention, while the CPU remains in deep sleep or software standby mode.

The R5F51115AGFL#3A operates at up to 32 MHz when supplied with 2.7 V to 3.6 V. At 1.8 V to 2.4 V, max frequency is 8 MHz; at 2.4 V to 2.7 V, it is 16 MHz. This voltage-frequency scaling ensures robust operation across wide input conditions while minimizing dynamic power in battery-powered R5F51115AGFL#3A designs.
Does the R5F51115AGFL#3A support USB On-The-Go (OTG)?
Yes, the R5F51115AGFL#3A includes a USB 2.0 full-speed host/function/OTG module with integrated transceiver. It supports dual-role operation, BC (Battery Charger) detection, and isochronous transfers-enabling R5F51115AGFL#3A to act as either a USB device (e.g., virtual COM port) or host (e.g., for flash drives) without external PHY components.
How many A/D and D/A channels does the R5F51115AGFL#3A provide?
The R5F51115AGFL#3A integrates a 14-channel 12-bit A/D converter and two 8-bit D/A converters. Both DAC outputs (DA0, DA1) are available in the 48-pin LFQFP package (PLQP0048KB-A), matching the R5F51115AGFL#3A's pinout. The A/D supports double-trigger mode for synchronized sampling in motor control applications using R5F51115AGFL#3A.
What low-power modes are supported by the R5F51115AGFL#3A?
The R5F51115AGFL#3A offers three low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby, current drops to 0.44 μA while retaining RTC, IWDT, and RAM contents. Wakeup occurs in 4.8 μs via RTC alarm, external interrupt, or USB resume-making R5F51115AGFL#3A ideal for duty-cycled sensor nodes.
Is the R5F51115AGFL#3A qualified for IEC 60730 Class B compliance?
Yes, the R5F51115AGFL#3A includes hardware features required for IEC 60730 Class B: Clock Accuracy Measurement Circuit (CAC), Independent Watchdog Timer (IWDT) with dedicated oscillator, RAM test assist logic, and oscillation stop detection.
