Product details
Overview
R5F51116ADNE#2A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, 14-channel 12-bit ADC, dual 8-bit DACs, USB 2.0 full-speed host/function/OTG, and RTC - deployed in industrial HMI, sensor node controllers, and USB-connected embedded gateways.
For engineers reviewing the R5F51116ADNE#2A datasheet, R5F51116ADNE#2A pinout, R5F51116ADNE#2A application, or R5F51116ADNE#2A equivalent, this page delivers verified package mapping (PWQN0048KB-A, 48-pin HWQFN, 7 × 7 mm), confirmed low-power modes (software standby: 0.44 μA, 4.8 μs wake-up), USB OTG support, and validated alternative options for migration or second-sourcing.
Technical Context
The R5F51116ADNE#2A 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. It integrates an Event Link Controller (ELC) enabling direct module-to-module triggering without CPU intervention - critical for deterministic real-time response in motor control and sensor fusion.
Its clock system includes independent PLL, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and Clock Accuracy Measurement (CAC) circuit for IEC 60730 compliance. Power management supports three low-power modes, with software standby consuming just 0.44 μA and recovering in 4.8 μs - optimized for battery-backed applications requiring rapid wake-on-event.
