Product details
Overview
R5F51115ADNE#U0 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 KB on-chip flash, 16 KB SRAM, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, 12-bit A/D converter (14 channels), 8-bit D/A converter (2 channels), RTC, and operates across −40°C to +85°C in a 48-pin HWQFN package (7 × 7 mm, 0.5 mm pitch). It targets low-power embedded control in industrial sensors and USB-connected edge devices.
For engineers reviewing the R5F51115ADNE#U0 datasheet, R5F51115ADNE#U0 pinout, R5F51115ADNE#U0 application, or R5F51115ADNE#U0 equivalent, key selection considerations include its USB OTG capability with BC (Battery Charger) support, 1.0 µs A/D conversion time at 32 MHz, software standby mode (0.44 µA), and 48-pin HWQFN footprint optimized for space-constrained designs.
Technical Context
The R5F51115ADNE#U0 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its clock system includes a high-speed on-chip oscillator (32 MHz ±1% over −20°C to +85°C), PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), all managed via independent ICLK/PCLK/FCLK domains.
Peripheral coordination is handled by the Event Link Controller (ELC), which enables direct module-to-module triggering without CPU intervention-e.g., MTU2 timers can initiate A/D conversions or RSPI transfers while the CPU remains in software standby mode. The Data Transfer Controller (DTC) supports chain transfer across four modes, activated by 82 interrupt vectors including IRQ0–IRQ7 and NMI.
