Product details
Overview
R5F51305AGFN#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 12-bit A/D converter (17 channels), two 8-bit D/A outputs, capacitive touch sensing (36 channels), RTC, and IEC60730-compliant safety functions - deployed in industrial human-machine interfaces and consumer appliance control systems.
For engineers reviewing the R5F51305AGFN#30 datasheet, R5F51305AGFN#30 pinout, R5F51305AGFN#30 application, or R5F51305AGFN#30 equivalent, this page delivers verified package mapping (PLQP0080KB-B, 80-pin LFQFP), validated peripheral configuration (SCIg ×3, RIIC ×1, RSPI ×1, MTU2 ×6), confirmed low-power behavior (0.37 µA standby, 4.8 µs wake-up), and real-world alternative part comparisons for design continuity.
Technical Context
The R5F51305AGFN#30 implements the RXv1 core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling ultra-compact code and single-cycle 32×32 multiplication. Its clock system integrates HOCO (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and CAC for frequency accuracy monitoring.
Peripheral coordination is managed via ELC (47 event sources) and DTC (four transfer modes), allowing timer-triggered A/D conversion, background data flash programming (BGO), and CPU-sleep-linked module operation - critical for deterministic real-time response in touch-enabled control applications.
