Overview
R5F51105ADFL#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 dual SCI interfaces - deployed in industrial sensor nodes requiring low-power, deterministic real-time control.
For engineers reviewing the R5F51105ADFL#30 datasheet, R5F51105ADFL#30 pinout, R5F51105ADFL#30 application, or R5F51105ADFL#30 equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40°C to +85°C temperature grade, integrated CAC for IEC 60730 compliance, and software standby mode recovery in 4.8 μs.
Technical Context
The R5F51105ADFL#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 MTU2 (4-channel 16-bit timer with phase counting and input capture), CMT (2-channel 16-bit compare match), RSPI (16 Mbps master/slave), RIIC (400 kbps I²C/SMBus), and S12AD (1.0 μs min conversion time, double-trigger mode for motor control). All operate synchronously with PCLK up to 32 MHz.
