Product details
Overview
R5F51104AGFK#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 96 KB on-chip flash, 16 KB SRAM, 12-bit A/D converter with 14 channels, RTC, and dual SCI + RIIC + RSPI interfaces. It targets low-power industrial sensing and control applications requiring deterministic real-time response and IEC 60730 compliance.
For engineers reviewing the R5F51104AGFK#30 datasheet, R5F51104AGFK#30 pinout, R5F51104AGFK#30 application, or R5F51104AGFK#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 (CAC) for functional safety.
Technical Context
The R5F51104AGFK#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 includes a 64-bit accumulator for 32×32-bit multiply operations and dedicated hardware for division and barrel shifting.
Peripherals are clocked independently: ICLK (system, up to 32 MHz), PCLK (peripherals, up to 32 MHz), and FCLK (FlashIF, up to 32 MHz). The MTU2 timer unit provides four 16-bit channels with input capture, output compare, phase counting, and A/D trigger generation - all configurable via eight selectable clock sources including PCLK dividers and external MTCLK inputs.
