Product details
Overview
R5F51403ADFL#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, and integrated USB 2.0 full-speed host/function/OTG, LCD controller/driver (40×4 segment), capacitive touch sensing (12 channels), 12-bit A/D (17 ch), 12-bit D/A (2 ch), RTC, and CTSU - deployed in industrial HMI and portable medical devices requiring low-power operation and rich analog interface.
For engineers reviewing the R5F51403ADFL#10 datasheet, R5F51403ADFL#10 pinout, R5F51403ADFL#10 application, or R5F51403ADFL#10 equivalent, this page delivers verified package mapping (PLQP0100KB-A, 100-pin LFQFP), validated peripheral integration (USB, CTSU, LCD, dual DAC), confirmed low-power modes (software standby: 0.44 µA, 4.8 µs wake-up), and real-world alternative options for migration or sourcing continuity.
Technical Context
The R5F51403ADFL#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 directly routes 44 event signals between peripherals without CPU intervention - critical for deterministic low-latency response in motor control and sensor fusion.
Its clock system includes independent PLL, USB-dedicated PLL, IWDT-dedicated 15 kHz oscillator, and Clock Accuracy Measurement (CAC) circuit for IEC 60730 compliance. The MCU supports three low-power modes - sleep, deep sleep, and software standby - with LPT running during standby and RTC capable of initiating wake-up via alarm or calendar events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51403ADFP#3A | Same RX113 Group, identical 256 KB flash/32 KB RAM, but in 100-pin LFQFP (PLQP0100KB-A) with same pinout and thermal profile | No CTSU or LCD support; targets cost-optimized designs where touch/display are handled externally | Select when CTSU/LCD integration is unnecessary and PCB layout rework is unacceptable |
| R5F51305ADFP#3A | RX130 Group part: higher CTSU channel count (24 vs. 12), larger flash (384 KB), but lacks USB OTG and LCD controller | Optimized for touch-centric applications (e.g., appliance control panels) without embedded display or USB host capability | Choose for enhanced touch performance and larger code space where USB/LCD are delegated to companion ICs |
Compared with R5F51403ADFL#10, R5F51403ADFP#3A offers identical core functionality in the same package but omits CTSU and LCD - reducing BOM cost where those features are unused; R5F51305ADFP#3A trades USB/LCD for superior touch scalability and memory, better suited for touch-first systems without integrated display.
