Product details
Overview
R5F51104AGFL#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 + I²C + RSPI interfaces. It targets low-power industrial sensor nodes and battery-powered control modules requiring deterministic real-time response and IEC 60730 compliance.
For engineers reviewing the R5F51104AGFL#30 datasheet, R5F51104AGFL#30 pinout, R5F51104AGFL#30 application, or R5F51104AGFL#30 equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40°C to +105°C extended temperature grade, 1.8–3.6 V single-supply operation, software standby mode (0.35 μA), and integrated clock accuracy measurement circuit (CAC) for functional safety.
Technical Context
The R5F51104AGFL#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.
Peripheral integration centers on deterministic real-time control: MTU2 provides four 16-bit timer channels with input capture, phase counting, and A/D trigger generation; DTC supports chain transfer across four interrupt sources; and the RIIC interface operates at up to 400 kbps in master/slave mode with SMBus compatibility.
