Product details
Overview
R5F51104ADFK#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 96 KB on-chip flash, 16 KB SRAM, 12-bit A/D converter with 14 channels, RTC, and dual SCI + I²C + RSPI interfaces. It targets low-power industrial sensing and control applications requiring deterministic real-time response and IEC 60730 compliance.
For engineers reviewing the R5F51104ADFK#30 datasheet, R5F51104ADFK#30 pinout, R5F51104ADFK#30 application, or R5F51104ADFK#30 equivalent, key selection criteria include its 64-pin LQFP (PLQP0064GA-A) package, −40°C to +85°C temperature grade, software standby mode (0.35 μA), and integrated clock accuracy measurement circuit for functional safety.
Technical Context
The R5F51104ADFK#30 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its on-chip peripherals include MTU2 (4-channel 16-bit timer), CMT (2-channel 16-bit compare match timer), and DTC supporting chain transfer for efficient data movement without CPU intervention.
It integrates dedicated oscillators - high-speed on-chip (32 MHz ±1%), sub-clock (32.768 kHz), and IWDT-dedicated (15 kHz) - with clock frequency accuracy measurement (CAC) and low-voltage detection (LVD) circuits. The MCU supports IEC 60730 Class B compliance via RAM test assist functions, IWDT, and CAC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum operating frequency and associated performance of the R5F51104ADFK#30?
The R5F51104ADFK#30 operates at a maximum frequency of 32 MHz, delivering 50 DMIPS of processing performance. This speed is achievable only when the supply voltage is ≥2.7 V. At lower voltages (1.8–2.4 V), the maximum frequency is reduced to 8 MHz to ensure stable operation and meet process variation margins.
Does the R5F51104ADFK#30 support IEC 60730 Class B compliance out of the box?
Yes, the R5F51104ADFK#30 includes hardware features required for IEC 60730 Class B: clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, and RAM test assist functions. These enable certified self-test routines without external components, though final system-level validation remains the designer's responsibility.
What package type and pin count does the R5F51104ADFK#30 use?
The R5F51104ADFK#30 uses the PLQP0064GA-A package: a 64-pin LQFP with 14 × 14 mm body size and 0.8 mm pin pitch. This is distinct from the 0.5 mm pitch LFQFP variant (PLQP0064KB-A) used by other RX110 members like R5F51104ADFM#30.
How many A/D converter channels does the R5F51104ADFK#30 provide, and what is their resolution and speed?
The R5F51104ADFK#30 integrates a single 12-bit successive-approximation A/D converter with 14 input channels. 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 via ADTRG0#.
What communication interfaces are available on the R5F51104ADFK#30?
The R5F51104ADFK#30 provides up to five serial interfaces: two SCI channels (SCI1 and SCI5) supporting asynchronous, clock-synchronous, and simple I²C/SPI modes; one SCIf channel (SCI12); one I²C bus interface (RIIC); and one RSPI channel. All support configurable data length, LSB/MSB order, and hardware flow control where applicable.
