Product details
Overview
R5F51101ADFK#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 32 KB on-chip 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 battery-powered control modules requiring deterministic real-time response.
For engineers reviewing the R5F51101ADFK#30 datasheet, R5F51101ADFK#30 pinout, R5F51101ADFK#30 application, or R5F51101ADFK#30 equivalent, this page delivers verified specifications, package mapping, functional pin roles, and validated alternative options for embedded design validation and BOM optimization.
Technical Context
The R5F51101ADFK#30 implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system integrates high-speed (32 MHz ±1%), sub-clock (32.768 kHz), and IWDT-dedicated (15 kHz) oscillators with on-chip frequency accuracy measurement (CAC).
Peripheral integration includes MTU2 (4-channel 16-bit timer with phase counting and trigger generation), CMT (2-channel 16-bit compare match), 12-bit S12AD with 1.0 µs conversion time and double-trigger mode, and RIIC/I²C bus interface supporting 400 kbps SMBus operation - all synchronized to independent PCLK domains.

The 32 MHz clock enables real-time execution of control loops and communication stacks without wait states on its 32 KB flash and 10 KB SRAM.
Does the R5F51101ADFK#30 support IEC 60730 functional safety compliance?
Yes, the R5F51101ADFK#30 includes integrated hardware features for IEC 60730 Class B compliance: clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, RAM test assist functions, and voltage monitoring circuits. These reduce external component count and simplify safety certification for industrial control applications.
What package type and pin count does the R5F51101ADFK#30 use?
The R5F51101ADFK#30 uses the PLQP0064GA-A package: a 64-pin LQFP with 14 × 14 mm body size and 0.8 mm pin pitch. This package provides 50 general-purpose I/O pins, full peripheral access (including all 14 A/D channels and dual SCI), and compatibility with standard reflow soldering processes.
Can the R5F51101ADFK#30 operate from a single 3.3 V supply?
Yes, the R5F51101ADFK#30 supports a supply voltage range of 1.8 V to 3.6 V. At 3.3 V, it achieves its full 32 MHz maximum operating frequency. The device also supports lower frequencies (16 MHz at 2.4–2.7 V, 8 MHz at 1.8–2.4 V) for dynamic power scaling in battery-operated systems.
What communication interfaces are integrated into the R5F51101ADFK#30?
The R5F51101ADFK#30 integrates three primary communication interfaces: two Serial Communications Interfaces (SCI1 and SCI5) supporting asynchronous, clock-synchronous, and Smart Card modes; one I²C bus interface (RIIC) compliant with 400 kbps Fast Mode and SMBus; and one Serial Peripheral Interface (RSPI) capable of 16 Mbps master/slave operation with 128-bit TX/RX buffers.
