Product details
Overview
R5F51117AGNE#2A from Renesas is a 32-bit RX111 Group microcontroller featuring a 32 MHz CPU core delivering 50 DMIPS, 384 KB on-chip flash memory with zero wait states, 64 KB SRAM, and integrated USB 2.0 full-speed host/function/OTG controller. It includes a 12-bit A/D converter (14 channels), 8-bit D/A converter (2 channels), RTC with calendar mode, and operates from 1.8–3.6 V across −40 to +105°C - deployed in industrial sensor nodes and USB-connected embedded control systems.
For engineers reviewing the R5F51117AGNE#2A datasheet, R5F51117AGNE#2A pinout, R5F51117AGNE#2A application, or R5F51117AGNE#2A equivalent, key selection criteria include its HWQFN-48 package (7 × 7 mm, 0.5 mm pitch), USB OTG support with BC (Battery Charger) compliance, dual 16-bit timer units (MTU2 + CMT), and IEC 60730-ready safety features including IWDT and clock accuracy measurement (CAC).
Technical Context
The R5F51117AGNE#2A implements a CISC Harvard architecture RX CPU with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system integrates PLL, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), enabling precise timing control across sleep modes and real-time functions.
Peripheral coordination is managed via Event Link Controller (ELC), allowing direct module triggering without CPU intervention, and Data Transfer Controller (DTC) supporting chain transfers across four modes. The MCU supports background operation (BGO) for 8 KB data flash with 1M erase/write cycles, and double-trigger A/D conversion for motor control synchronization.
