Product details
Overview
R5F51103ADFL#30 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, 12-bit A/D converter with 14 channels, RTC, and dual SCI interfaces - deployed in industrial sensor nodes requiring low-power operation and deterministic real-time control.
For engineers reviewing the R5F51103ADFL#30 datasheet, R5F51103ADFL#30 pinout, R5F51103ADFL#30 application, or R5F51103ADFL#30 equivalent, key selection criteria include its 48-pin LFQFP package, −40°C to +85°C temperature grade, software standby mode (0.35 μA), and integrated IEC 60730 support for functional safety compliance.
Technical Context
The R5F51103ADFL#30 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its RX CPU core includes a 64-bit accumulator for 32×32-bit multiply operations and dedicated hardware for division and barrel shifting.
On-chip clock generation supports multiple sources: high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and external crystal up to 20 MHz. The system clock (ICLK), peripheral clock (PCLK), and FlashIF clock (FCLK) are independently configurable, all scalable up to 32 MHz.

FAQ
What is the maximum operating frequency and associated power supply requirement for the R5F51103ADFL#30?
The R5F51103ADFL#30 operates at a maximum frequency of 32 MHz, which requires a VCC supply of 2.7–3.6 V. At 1.8–2.4 V, maximum frequency is limited to 8 MHz; at 2.4–2.7 V, it is 16 MHz. This voltage-frequency scaling ensures robust operation across varying battery or rail conditions while maintaining timing accuracy.
Does the R5F51103ADFL#30 include hardware support for functional safety standards like IEC 60730?
Yes, the R5F51103ADFL#30 integrates dedicated hardware for IEC 60730 Class B compliance, including a clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, and RAM test assist functions - all documented in the R01DS0202EJ0120 datasheet.
How many serial communication interfaces does the R5F51103ADFL#30 support, and what protocols are implemented?
The R5F51103ADFL#30 supports three serial interfaces: two SCIe modules (channels 1 and 5) and one SCIf module (channel 12), each capable of asynchronous, clock-synchronous, simple I2C, and simple SPI modes. Additionally, it includes one dedicated RIIC channel (I2C/SMBus) and one RSPI channel (SPI master/slave up to 16 Mbps).
What A/D converter capabilities does the R5F51103ADFL#30 provide, and how is conversion triggered?
The R5F51103ADFL#30 features a 12-bit A/D converter with 14 input channels and a minimum conversion time of 1.0 µs at 32 MHz ADCLK. Conversion can be initiated by software command, external pin (ADTRG0#), or timer trigger (MTU channel output), and supports double-trigger mode for duplicated result capture in motor control applications.
What package type and pin count does the R5F51103ADFL#30 use, and is it pin-compatible with other RX110 variants?
The R5F51103ADFL#30 uses the PLQP0048KB-A package: a 48-pin LFQFP with 7 × 7 mm body and 0.5 mm pitch. It is pin-compatible with all other RX110 Group members in the same 48-pin LFQFP variant (e.g., R5F51101ADFL#30, R5F51104ADFL#30), sharing identical pin functions and electrical characteristics per the R01DS0202EJ0120 datasheet.
