Product details
Overview
R5F51101AGFK#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 sensing and control applications requiring deterministic real-time response and IEC 60730 compliance.
For engineers reviewing the R5F51101AGFK#30 datasheet, R5F51101AGFK#30 pinout, R5F51101AGFK#30 application, or R5F51101AGFK#30 equivalent, key selection criteria include its 64-pin LQFP (PLQP0064GA-A) package, −40 to +105°C extended temperature grade, software standby mode (0.35 μA), and integrated clock accuracy measurement circuit (CAC) for functional safety validation.
Technical Context
The R5F51101AGFK#30 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its RX CPU core supports 64-bit accumulator operations and includes dedicated hardware for multiplication/division (one-cycle multiply).
On-chip peripherals are clocked independently: system clock (ICLK) up to 32 MHz, peripheral clock (PCLK) up to 32 MHz, and FlashIF clock (FCLK) up to 32 MHz. Clock sources include high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and external crystal (up to 20 MHz), all managed by a configurable clock generation circuit with oscillation stop detection.
