Product details
Overview
R5F51105AGFK#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 Kbytes of on-chip flash, 16 Kbytes of SRAM, a 12-bit A/D converter with 14 channels, RTC, and five communication interfaces including SCI, I²C, and RSPI - deployed in industrial sensor nodes and low-power HMI control units.
For engineers reviewing the R5F51105AGFK#30 datasheet, R5F51105AGFK#30 pinout, R5F51105AGFK#30 application, or R5F51105AGFK#30 equivalent, key selection criteria include its −40 to +105°C extended temperature grade, LQFP-64 (PLQP0064GA-A) package, 32 MHz high-speed on-chip oscillator (±1%), software standby mode (0.35 μA), and IEC 60730-compliant safety features.
Technical Context
The R5F51105AGFK#30 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle 32×32-bit multiplication. Its on-chip clock generation includes independent system (ICLK), peripheral (PCLK), and FlashIF (FCLK) domains, all configurable up to 32 MHz.
It integrates a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 65 interrupt vectors, and a Real-time Clock (RTCA) with calendar count mode, leap-year correction, and software-standby wake-up capability - all validated for operation across −40 to +105°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51105AGFM#30 | Same core, memory, and peripherals; differs only in package (LFQFP-64, 10×10 mm, 0.5 mm pitch vs. LQFP-64, 14×14 mm, 0.8 mm pitch) | Requires PCB layout change due to footprint and pitch mismatch; identical thermal and electrical behavior | Select when board space is constrained and finer-pitch assembly is available |
| R5F51105ADFK#30 | Identical package and pinout; rated for −40 to +85°C (vs. +105°C) and lacks extended temperature qualification | Not suitable for under-hood automotive or industrial enclosures exceeding 85°C ambient | Select for cost-sensitive commercial applications where extended temperature range is unnecessary |
Compared with R5F51105AGFM#30, the R5F51105AGFK#30 offers larger pad pitch for easier rework and higher thermal mass, while versus R5F51105ADFK#30 it provides guaranteed operation up to +105°C - critical for sealed industrial enclosures and long-term reliability validation.

FAQ
What is the maximum operating frequency and associated power supply requirement for the R5F51105AGFK#30?
The R5F51105AGFK#30 operates at a maximum frequency of 32 MHz, which requires a VCC supply between 2.7 V and 3.6 V. At lower voltages (1.8–2.4 V), the maximum frequency is reduced to 8 MHz; at 2.4–2.7 V, it is 16 MHz. This voltage-frequency scaling ensures stable operation across diverse power environments while maintaining low dynamic power consumption.
Does the R5F51105AGFK#30 support IEC 60730 Class B compliance out of the box?
Yes, the R5F51105AGFK#30 includes hardware features required for IEC 60730 Class B compliance: a clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, RAM test assist functions, and voltage monitoring circuits. These are documented in the R01DS0202EJ0120 datasheet and validated for use in safety-critical appliance and industrial control applications.
What communication interfaces are integrated into the R5F51105AGFK#30, and how many channels does each support?
The R5F51105AGFK#30 integrates three SCI modules (SCI1, SCI5, SCI12), one I²C bus interface (RIIC), and one RSPI interface. SCI1 and SCI5 support asynchronous, clock-synchronous, and Smart Card modes; SCI12 adds extended serial functionality. The RIIC supports master/slave operation at up to 400 kbps, and RSPI operates at up to 16 Mbps with four-frame burst capability - all accessible via the R5F51105AGFK#30's 64-pin LQFP package.
How does the R5F51105AGFK#30 manage low-power operation, and what is its lowest achievable current draw?
The R5F51105AGFK#30 supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode - where the CPU, flash, and most peripherals are halted but RTC and IWDT remain active - the typical current draw is 0.35 μA at VCC = 3.0 V and TA = 25°C. Wake-up occurs in 4.8 μs via RTC alarm, external interrupt, or IWDT timeout, making the R5F51105AGFK#30 suitable for multi-year battery operation.
What is the A/D converter specification of the R5F51105AGFK#30, and does it support simultaneous sampling?
The R5F51105AGFK#30 features a 12-bit successive-approximation A/D converter (S12AD) with up to 14 input channels and a minimum conversion time of 1.0 µs at 32 MHz ADCLK. It supports double-trigger mode - capturing two consecutive conversions on the same channel - but does not support true simultaneous sampling across multiple channels. Trigger sources include software, MTU timers, or external signals like ADTRG0#.
