Product details
Overview
R5F51114ADNE#UA from Renesas is a 32-bit RX CPU core microcontroller operating at up to 32 MHz (50 DMIPS), featuring 96 KB on-chip flash, 16 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 and sensor gateway edge nodes.
For engineers reviewing the R5F51114ADNE#UA datasheet, R5F51114ADNE#UA pinout, R5F51114ADNE#UA application, or R5F51114ADNE#UA equivalent, key selection criteria include its HWQFN-48 package (7 × 7 mm, 0.5 mm pitch), −40°C to +85°C temperature grade, USB OTG support with BC (Battery Charger) compliance, and integrated event link controller (ELC) for low-power peripheral coordination without CPU wake-up.
Technical Context
The R5F51114ADNE#UA implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its on-chip peripherals include a 35-event ELC for direct module-to-module triggering and a DTC supporting normal, repeat, and block transfer modes activated by 82 interrupt vectors.
It integrates a high-speed on-chip oscillator (32 MHz ±1% over −20°C to +85°C), clock frequency accuracy measurement circuit (CAC), and independent watchdog timer (IWDT) driven by a dedicated 15 kHz oscillator - all supporting IEC 60730 functional safety requirements for Class B applications.
