R5F51103ADFK#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 64 Kbytes of on-chip flash, 10 Kbytes of SRAM, and integrated peripherals including 14-channel 12-bit ADC, RTC, dual SCI interfaces, I²C, RSPI, MTU2 timers, and temperature sensor - deployed in industrial sensor nodes and low-power HMI control units.
For engineers reviewing the R5F51103ADFK#30 datasheet, R5F51103ADFK#30 pinout, R5F51103ADFK#30 application, or R5F51103ADFK#30 equivalent, key selection criteria include its −40 to +85°C temperature grade, 64-pin LQFP (PLQP0064GA-A) package, software standby current of 0.35 μA, 4.8 μs wake-up time, and IEC 60730-compliant safety features for embedded control.
Technical Context
The R5F51103ADFK#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 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 a 4-channel MTU2 timer unit supporting input capture, phase counting, and A/D trigger generation; two CMT channels; one RIIC interface (400 kbps I²C/SMBus); one RSPI (16 Mbps); and dual SCI modules (SCI1/SCI5) supporting asynchronous, clock-synchronous, and simple I²C/SPI modes - all synchronized to programmable PCLK domains.
