Overview
R5F51111AGFL#1A 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, and 8 KB data flash. It integrates a 12-bit A/D converter (14 channels, 1.0 µs conversion), USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and operates across −40 to +105°C in industrial applications such as smart sensors and USB-connected edge devices.
For engineers reviewing the R5F51111AGFL#1A datasheet, R5F51111AGFL#1A pinout, R5F51111AGFL#1A application, or R5F51111AGFL#1A equivalent, this page delivers verified specifications, package mapping to PLQP0048KB-A (48-pin LFQFP, 7 × 7 mm, 0.5 mm pitch), functional pin roles, real-world use cases, and two validated alternative parts - all derived from Renesas R01DS0190EJ0130 Rev.1.30.
Technical Context
The R5F51111AGFL#1A implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and CAC for frequency accuracy monitoring.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables direct module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers triggered by 35+ event sources. The MCU supports IEC 60730-compliant safety functions including IWDT with dedicated 15 kHz oscillator and RAM test assist logic.
