Product details
Overview
R5F51113ADFL#1A 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 a 12-bit A/D converter (14 channels, 1.0 µs conversion), USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and operates from 1.8–3.6 V across −40 to +85°C - deployed in industrial sensor nodes and USB-connected embedded control systems.
For engineers reviewing the R5F51113ADFL#1A datasheet, R5F51113ADFL#1A pinout, R5F51113ADFL#1A application, or R5F51113ADFL#1A equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, dual 8-bit D/A outputs (available only in 64-pin variants), absence of D/A in this variant, and confirmed support for SCI ×2, RIIC ×1, RSPI ×1, and USB OTG with BC (Battery Charger) compliance.
Technical Context
The R5F51113ADFL#1A implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and CAC for frequency accuracy monitoring.
Peripheral coordination is managed via Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention, and Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 82 interrupt sources - critical for deterministic real-time response in motor control and sensor fusion applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RX 32-bit CISC Harvard, 32 MHz max, 50 DMIPS - enables compact code density and deterministic interrupt latency for real-time firmware. |
| Memory | 64 KB flash (no wait states @32 MHz), 10 KB SRAM, 8 KB data flash (1M erase/write cycles) - supports field firmware updates and parameter storage without external EEPROM. |
| A/D Converter | 12-bit resolution, 14-channel input, 1.0 µs min conversion time - suitable for fast closed-loop control sampling in motor drives and power supplies. |
| USB Interface | USB 2.0 full-speed (12 Mbps) host/function/OTG with BC (Battery Charger) detection - enables direct USB peripheral attachment and charging-aware device operation. |
| Operating Range | 1.8–3.6 V supply, −40 to +85°C ambient - validated for industrial-grade deployment in unregulated power environments. |
| Low-Power Modes | Software standby mode (0.44 µA), 4.8 µs wake-up - extends battery life in portable instrumentation and wireless edge nodes. |
| Real-Time Clock | RTC with leap-year correction, calendar/binary count modes, and software-standby wake capability - provides accurate timekeeping without external RTC IC. |
Pinout & Package
Package: 48-pin LFQFP (PLQP0048KB-A), 7 × 7 mm, 0.5 mm pitch, exposed pad optional - compatible with standard reflow profiles and mid-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply and ground | Dual 3.3 V supply domains (core/analog); decoupling required per Renesas layout guidelines to ensure ADC accuracy and USB signal integrity. |
| XTAL / EXTAL | Main crystal oscillator interface | Supports 1–20 MHz external crystals; used for precise system clock generation when high accuracy is required over internal oscillator. |
| USB0_DP / USB0_DM | USB 2.0 differential data pair | On-chip transceiver with full-speed PHY; requires 90 Ω differential impedance routing and ESD protection per USB-IF compliance. |
| AN000–AN015 | Analog input channels | 14 dedicated A/D inputs (subset available per package); AVCC0/AVSS0 must be separately filtered for noise-sensitive measurements. |
| P03, P14–P17, PC0–PC7, etc. | General-purpose I/O | 5-V tolerant, configurable pull-up/open-drain; MPC allows dynamic peripheral function remapping - simplifies board reuse across firmware variants. |
| RES# | Active-low reset input | Asynchronous hardware reset; debounced externally or via internal POR/LVD circuits - ensures reliable startup under brownout conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Event Link Controller (ELC) | Direct hardware linking of 35 event sources (e.g., timer overflow → ADC trigger) eliminates CPU polling overhead and reduces jitter in time-critical sequences. |
| Data Transfer Controller (DTC) | Four transfer modes with chain capability - offloads memory-mapped peripheral data movement (e.g., RSPI receive buffer → RAM) without CPU involvement. |
| Background Operation (BGO) | Data flash erase/write while CPU executes code - enables seamless firmware updates and logging without application interruption. |
| Clock Accuracy Measurement (CAC) | On-chip circuit compares internal oscillator against external reference - satisfies IEC 60730 Class B requirements for clock monitoring in safety-critical appliances. |
| IEC 60730 Support | Integrated IWDT, RAM test assist, and CAC - reduces certification effort for white goods, HVAC, and medical auxiliary controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51113ADFM#3A | 64-pin LFQFP (PLQP0064KB-A), adds 2× 8-bit D/A outputs and 4 additional GPIOs; same flash/RAM/peripherals. | Required where analog output (e.g., bias voltage generation) or expanded I/O is needed - not drop-in due to package and pinout change. | Select R5F51113ADFM#3A only if D/A outputs or extra pins are mandatory; verify PCB redesign for 64-pin footprint and thermal pad. |
| R5F51111ADFL#3A | 32 KB flash, 10 KB RAM, identical package/peripherals - reduced code capacity but same power/performance envelope. | Suitable for cost-sensitive, fixed-function devices with smaller firmware footprints (e.g., simple sensor transmitters). | Choose R5F51111ADFL#3A when application firmware fits ≤32 KB and long-term code growth is constrained - no hardware changes needed. |
Compared with R5F51113ADFL#1A, R5F51113ADFM#3A offers expanded analog I/O at the cost of larger footprint and layout revision, while R5F51111ADFL#3A trades flash capacity for lower unit cost in static-function deployments - both retain identical USB, A/D, and low-power behavior.

FAQ
Does R5F51113ADFL#1A include an integrated USB transceiver?
Yes, R5F51113ADFL#1A integrates a full-speed USB 2.0 transceiver compliant with USB 2.0 specifications, supporting host, function, and OTG roles. It includes dedicated USB I/O pins (USB0_DP/USB0_DM), VBUS sensing (USB0_VBUS), and OTG control signals (USB0_ID, USB0_EXICEN). No external PHY is required for basic USB communication.
What is the maximum A/D conversion rate supported by R5F5113ADFL#1A?
R5F51113ADFL#1A supports a minimum A/D conversion time of 1.0 µs per channel when the ADCLK runs at 32 MHz, enabling up to 1 MSPS sampling on a single channel. With scan mode and DTC-assisted transfers, sustained multi-channel acquisition at ≥500 kSPS is achievable - verified in Renesas Application Note R01AN2313.
Is the 8-bit D/A converter available on R5F51113ADFL#1A?
No, the 8-bit D/A converter (DA0/DA1) is not available on R5F51113ADFL#1A. According to Table 1.2 in the datasheet, D/A functionality is only supported in 64-pin package variants (e.g., R5F51113ADFM#3A). The R5F51113ADFL#1A uses the 48-pin LFQFP (PLQP0048KB-A) package, which omits D/A outputs per Renesas' package-specific peripheral mapping.
What low-power modes does R5F51113ADFL#1A support, and what is the wake-up latency from software standby?
R5F51113ADFL#1A supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, supply current drops to 0.44 µA (typ.), and wake-up latency is 4.8 µs - measured from interrupt/event assertion to first instruction fetch. RTC alarm or external pin interrupt can initiate wake-up, preserving register context.
How many communication interfaces does R5F51113ADFL#1A provide, and which are included in the 48-pin package?
R5F51113ADFL#1A provides up to six communication channels: USB 2.0 (1 port), SCI ×2 (SCI1/SCI5), RIIC ×1, and RSPI ×1. All are present in the 48-pin LFQFP package. SCI12 and SSLA1–SSLA3 are excluded per Table 1.2, confirming SCI1/SCI5, RIIC, and RSPI remain fully functional - sufficient for dual-sensor interfacing plus USB host/device bridging.
