Product details
Overview
R5F51115ADFL#V0 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, 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 R5F51115ADFL#V0 datasheet, R5F51115ADFL#V0 pinout, R5F51115ADFL#V0 application, or R5F51115ADFL#V0 equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40°C to +85°C temperature grade, integrated USB transceiver with BC support, dual 8-bit D/A outputs, and ELC-assisted peripheral coordination without CPU wake-up.
Technical Context
The R5F51115ADFL#V0 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. Its clock system integrates PLL, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and CAC for IEC 60730 compliance.
Peripheral coordination is managed via Event Link Controller (ELC), enabling direct module-to-module triggering (e.g., MTU2 → S12AD start) while 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.
