Renesas R5F51113AGFL#3A

Overview

R5F51113AGFL#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 64 KB on-chip flash, 10 KB SRAM, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, 12-bit A/D converter (14 channels), 8-bit D/A converter (2 channels), RTC, and operates across −40°C to +105°C in a 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch) package for industrial motor control and embedded USB device applications.

For engineers reviewing the R5F51113AGFL#3A datasheet, R5F51113AGFL#3A pinout, R5F51113AGFL#3A application, or R5F51113AGFL#3A equivalent, key selection considerations include its 32 MHz real-time performance, integrated USB transceiver with OTG support, dual 8-bit DAC outputs, 14-channel 12-bit ADC with 1.0 µs conversion time, and software standby mode recovery in 4.8 µs.

Technical Context

The R5F51113AGFL#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 includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), with independent ICLK/PCLK/FCLK domains.

Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables direct module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers triggered by 35+ event sources. The MTU2 timer unit provides six 16-bit channels with complementary PWM, phase counting, and A/D trigger generation - critical for motor control timing precision.

FAQ

What is the maximum operating frequency and core performance of the R5F51113AGFL#3A?

The R5F51113AGFL#3A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS using its 32-bit RX CPU core. This performance is achieved with zero-wait-state flash access and a five-stage pipeline architecture. The R5F51113AGFL#3A maintains deterministic real-time behavior even under full load due to its CISC Harvard design and single-cycle instruction execution capability.

Does the R5F51113AGFL#3A support USB On-The-Go (OTG) functionality?

Yes, the R5F51113AGFL#3A integrates a USB 2.0 full-speed host/function/OTG module with an on-chip transceiver. It supports OTG role switching, BC (Battery Charger) detection, and isochronous transfers. The R5F51113AGFL#3A uses USB0_ID, USB0_VBUS, and USB0_EXICEN pins to manage OTG state transitions and power negotiation without external level shifters or PHY components.

What are the analog capabilities of the R5F51113AGFL#3A, particularly regarding ADC and DAC?

The R5F51113AGFL#3A includes a 12-bit A/D converter with 14 input channels and a minimum conversion time of 1.0 µs at 32 MHz ADCLK, plus two 8-bit D/A converters (DA0 and DA1) with 0–VCC output range. The R5F51113AGFL#3A supports double-trigger mode for synchronized sampling and uses dedicated analog supply pins (AVCC0/AVSS0/VREFH0/VREFL0) to ensure noise immunity in mixed-signal applications.

How does the R5F51113AGFL#3A handle low-power operation in industrial environments?

The R5F51113AGFL#3A offers three low-power modes including software standby drawing just 0.44 µA, with wake-up in 4.8 µs - critical for battery-backed or energy-harvested systems. Its −40°C to +105°C operating range and built-in voltage detectors (LVDA) ensure reliable reset and brown-out protection across harsh industrial conditions. The R5F51113AGFL#3A achieves 0.11 mA/MHz in active mode, balancing performance and efficiency.

Is the R5F51113AGFL#3A pin-compatible with other members of the RX111 Group?

The R5F51113AGFL#3A shares the same 48-pin LFQFP (PLQP0048KB-A) package and pinout with other RX111 variants in the FL suffix family (e.g., R5F51115AGFL#3A, R5F51116AGFL#3A), enabling memory-size scalability without PCB redesign. However, it is not pin-compatible with FM/FK/NE/NF packages due to differing pin counts and assignments. Always verify peripheral mapping in Table 1.2 of the R01DS0190EJ0130 datasheet before substitution.
