Product details
Overview
R5F51103AGFK#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, 14-channel 12-bit A/D converter (1.0 µs conversion), RTC with calendar mode, and dual SCI + RIIC + RSPI interfaces. It targets low-power industrial sensor nodes and embedded control systems requiring IEC 60730 compliance.
For engineers reviewing the R5F51103AGFK#30 datasheet, R5F51103AGFK#30 pinout, R5F51103AGFK#30 application, or R5F51103AGFK#30 equivalent, key selection criteria include its 64-pin LQFP (PLQP0064GA-A) package, −40 to +105°C temperature grade, software standby current of 0.35 µA, and integrated CAC/IWDT for functional safety support.
Technical Context
The R5F51103AGFK#30 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle 32×32-bit multiply. Its clock system integrates high-speed (32 MHz ±1%), sub-clock (32.768 kHz), and IWDT-dedicated (15 kHz) oscillators with CAC for accuracy monitoring.
Peripheral integration includes MTU2 (4×16-bit timer channels with phase counting and input capture), CMT (2×16-bit), DTC with chain transfer, and 12-bit S12AD supporting double-trigger mode for motor control. The MCU supports IEC 60730 via RAM test assist, clock monitoring, and independent watchdog functions.

FAQ
What is the maximum operating frequency and performance of the R5F51103AGFK#30?
The R5F51103AGFK#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its RX CPU core features a five-stage pipeline, variable-length instruction encoding, and single-cycle 32×32-bit multiplication-enabling efficient execution of real-time control algorithms and protocol stacks without external acceleration. This performance level is sustained across its full −40 to +105°C operating range.
Does the R5F51103AGFK#30 support IEC 60730 Class B compliance?
Yes, the R5F51103AGFK#30 includes dedicated hardware features for IEC 60730 Class B compliance: Clock Frequency Accuracy Measurement Circuit (CAC), Independent Watchdog Timer (IWDT) with dedicated 15 kHz oscillator, Low-Voltage Detection (LVD) with 10 selectable thresholds, and RAM test assist functions. These are documented in the R01DS0202EJ0120 datasheet and enable certified self-test routines in safety-critical applications like home appliances.
What are the supported package types and pin counts for the R5F51103AGFK#30?
The R5F51103AGFK#30 is specifically packaged in the PLQP0064GA-A: a 64-pin LQFP with 14 × 14 mm body size and 0.8 mm pin pitch. This package is distinct from other RX110 variants such as the 10×10 mm LFQFP (PLQP0064KB-A) or 7×7 mm HWQFN (PWQN0048KB-A). Pin compatibility is limited to other 64-pin RX110 parts sharing the same pin assignment table (e.g., R5F51103AGFM#30 uses different pinout despite same pin count).
How does the A/D converter in the R5F51103AGFK#30 support motor control applications?
The R5F51103AGFK#30 integrates a 12-bit S12AD converter with 14 input channels and a 1.0 µs minimum conversion time at 32 MHz ADCLK. Its double-trigger mode duplicates conversion results for redundancy, and MTU2 timer outputs can serve as precise hardware triggers-enabling synchronized sampling of multiple motor phases or current/voltage feedback signals without CPU intervention.
What communication interfaces are available on the R5F51103AGFK#30 and how are they allocated?
The R5F51103AGFK#30 provides three SCI modules (SCI1, SCI5, SCI12), one RIIC (I²C/SMBus), and one RSPI (SPI master/slave). SCI1 and SCI5 support asynchronous, clock-synchronous, and Simple I²C/SPI modes; SCI12 adds extended serial (RXDX/TXDX/SIOX) for custom protocols. RIIC operates up to 400 kbps, and RSPI supports 16 Mbps with 8–32 bit frame sizes and double buffering-enabling concurrent sensor, display, and bus communication.
