Overview
R5F51114ADNE#2A 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, 8 KB data flash, 12-bit A/D converter (14 channels), USB 2.0 full-speed host/function/OTG, and RTC - deployed in industrial sensor nodes requiring deterministic real-time control and low-power connectivity.
For engineers reviewing the R5F51114ADNE#2A datasheet, R5F51114ADNE#2A pinout, R5F51114ADNE#2A application, or R5F51114ADNE#2A equivalent, key selection criteria include its 48-pin HWQFN (PWQN0048KB-A) package, −40°C to +85°C temperature grade, USB OTG support with BC (Battery Charger) detection, and integrated event link controller (ELC) for interrupt-free peripheral coordination.
Technical Context
The R5F51114ADNE#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 a dedicated 15 kHz IWDT oscillator and clock frequency accuracy measurement circuit (CAC) for IEC 60730 compliance.
Its peripheral set includes three SCI channels (SCI1/SCI5/SCI12), one RIIC, one RSPI, six MTU2 timer channels, two CMT units, and ELC-driven direct module linking - enabling synchronized operation of timers, ADC, and communication interfaces without CPU intervention during sleep modes.
