Product details
Overview
R5F51101ADFL#10 from Renesas is a 32-bit RX CPU core microcontroller operating at up to 32 MHz (50 DMIPS), featuring 32 KB flash, 10 KB SRAM, 12-bit A/D converter with 14 channels, RTC, and dual SCI + I²C + RSPI interfaces. It targets low-power industrial sensor nodes and embedded control systems requiring deterministic real-time response and IEC 60730 compliance.
For engineers reviewing the R5F51101ADFL#10 datasheet, R5F51101ADFL#10 pinout, R5F51101ADFL#10 application, or R5F51101ADFL#10 equivalent, key selection criteria include its 48-pin LFQFP package, −40°C to +85°C temperature grade, software standby mode (0.35 μA), 1.0 μs A/D conversion time, and integrated clock accuracy measurement circuit for functional safety validation.
Technical Context
The R5F51101ADFL#10 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code density. Its on-chip peripherals include a 4-channel MTU2 timer unit supporting phase counting and input capture, plus a 2-channel CMT for precise timing intervals.
It integrates dedicated hardware for functional safety: an independent watchdog timer (IWDT) driven by a 15 kHz on-chip oscillator, low-voltage detection (LVD) with 10 selectable thresholds, and a CRC calculator supporting X⁸+X²+X+1, X¹⁶+X¹⁵+X²+1, and X¹⁶+X¹²+X⁵+1 polynomials - all required for IEC 60730 Class B compliance.

How many serial communication interfaces does the R5F51101ADFL#10 provide, and what protocols do they support?
The R5F51101ADFL#10 provides three physical serial interfaces: two SCI channels (SCI1 and SCI5) supporting asynchronous UART, clock-synchronous, and smart card modes; one SCIf channel (SCI12) adding extended serial and simple SPI capabilities; one RIIC channel for I²C/SMBus up to 400 kbps; and one RSPI channel supporting master/slave SPI at up to 16 Mbps. All are accessible in the R5F51101ADFL#10's 48-pin package.
What is the A/D converter resolution, channel count, and minimum conversion time for the R5F51101ADFL#10?
The R5F51101ADFL#10 integrates a 12-bit successive-approximation A/D converter with 14 input channels (AN000–AN015). Minimum conversion time is 1.0 μs per channel when the A/D clock (ADCLK) runs at 32 MHz. It supports scan modes, double-trigger duplication for motor control, and external trigger start - all confirmed in the R5F51101ADFL#10 datasheet Section 1. Overview.
Which package type and pin count does the R5F51101ADFL#10 use, and what are its key mechanical dimensions?
