Product details
Overview
R5F51403ADFJ#10 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, 12-bit A/D (17 channels), 12-bit D/A (2 channels), USB 2.0 full-speed host/function/OTG, and capacitive touch sensing (12 channels) - deployed in industrial HMI, portable medical devices, and smart sensor nodes requiring integrated analog, timing, and human-interface functions.
For engineers reviewing the R5F51403ADFJ#10 datasheet, R5F51403ADFJ#10 pinout, R5F51403ADFJ#10 application, or R5F51403ADFJ#10 equivalent, this page delivers verified package mapping (100-pin LFQFP, PLQP0100KB-A), validated peripheral integration (USB, CTSU, RTC, ELC), confirmed low-power modes (software standby: 0.44 µA, 4.8 µs wake-up), and real-world design constraints including 5-V-tolerant I/O, 1.8–3.6 V supply, and –40 to +85°C operation.
Technical Context
The R5F51403ADFJ#10 implements the RXv1 core with CISC Harvard architecture, five-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates an Event Link Controller (ELC) that enables direct inter-module triggering without CPU intervention - critical for deterministic low-power operation in battery-powered systems.
Its clock system includes independent PLL, USB-dedicated PLL, IWDT-dedicated 15 kHz oscillator, and Clock Accuracy Measurement (CAC) circuit - all supporting IEC 60730 Class B compliance. The MCU supports three low-power modes (sleep, deep sleep, software standby), with LPT running during software standby using sub-clock or IWDT oscillator.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51403ADFP#3A | Same RX113 Group, identical peripherals and memory (256 KB flash/32 KB SRAM), but in 100-pin LFQFP with Sn-only terminal finish (#3A vs #10) | Identical functionality; differs only in packaging standard and tray material - suitable for Sn-only RoHS compliance programs | Select when Sn-only plating is mandated by assembly process or end-equipment specification. |
| R5F51402ADFP#3A | Lower memory variant: 128 KB flash / 32 KB SRAM; lacks CTSU and LCD controller; same 100-pin LFQFP package and temperature grade | Targeted at cost-sensitive sensor nodes without touch or display - missing 12-channel CTSU and LCD driver limits UI capability | Choose only if touch sensing and LCD drive are unnecessary and flash budget is constrained to ≤128 KB. |
Compared with R5F51403ADFJ#10, R5F51403ADFP#3A offers identical feature set with alternate plating, while R5F51402ADFP#3A removes CTSU and LCD to reduce cost - making the R5F51403ADFJ#10 optimal for touch-enabled, display-integrated designs requiring full peripheral availability and J-variant tray packaging.

FAQ
What is the maximum operating frequency and core performance of the R5F51403ADFJ#10?
The R5F51403ADFJ#10 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS performance using the 32-bit RXv1 CPU core. Its architecture includes a 64-bit accumulator for single-cycle 32×32 multiplication, five-stage pipeline, and variable-length instruction encoding - enabling high code density and deterministic real-time execution. This performance level is sustained across its full 1.8–3.6 V supply range.
Does the R5F51403ADFJ#10 support USB On-The-Go functionality?
Yes, the R5F51403ADFJ#10 integrates a USB 2.0 host/function module compliant with OTG (On-The-Go) specification. It supports full-speed (12 Mbps) and low-speed (1.5 Mbps) operation, isochronous transfers, and Battery Charging (BC) detection. The USB0_ID pin enables automatic role switching between host and device modes when used with a Mini-AB connector - essential for portable field-service tools and diagnostic equipment.
What are the key low-power capabilities of the R5F51403ADFJ#10?
The R5F51403ADFJ#10 offers three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it consumes just 0.44 µA while keeping the RTC, low-power timer (LPT), and capacitive touch sensing unit (CTSU) active - with wake-up in 4.8 µs. Its supply current is 3.6 mA at 32 MHz (typ.), and it supports dynamic voltage scaling via high/middle/low-speed operating modes to match processing demand.
How many analog-to-digital and digital-to-analog channels does the R5F51403ADFJ#10 include?
The R5F51403ADFJ#10 integrates a 12-bit successive-approximation A/D converter with up to 17 input channels (AN000–AN015, AN021), capable of 1.0 µs minimum conversion time at 32 MHz ADCLK. It also includes two 12-bit D/A converter channels (DA0, DA1) with output voltage range of 0.35 V to AVCC – 0.47 V - supporting closed-loop control, sensor calibration, and analog waveform generation.
Is the R5F51403ADFJ#10 pin-compatible with other RX113 Group MCUs?
Yes, the R5F51403ADFJ#10 shares the same 100-pin LFQFP (PLQP0100KB-A) package and pinout with other RX113 Group members in the 100-pin variant, including R5F51403ADFP#3A and R5F51402ADFP#3A. However, functional differences exist: R5F51403ADFJ#10 includes CTSU and LCD controller, while R5F51402ADFP#3A omits both. Pin compatibility enables footprint reuse, but firmware and layout must verify peripheral enablement.
