Product details
Overview
R5F51115ADFM#YB2 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, 14-channel 12-bit ADC (1.0 µs conversion), dual 8-bit DAC, RTC with calendar mode, and operates from 1.8–3.6 V across −40 to +85°C - deployed in industrial HMI and portable medical sensor nodes.
For engineers reviewing the R5F51115ADFM#YB2 datasheet, R5F51115ADFM#YB2 pinout, R5F51115ADFM#YB2 application, or R5F51115ADFM#YB2 equivalent, this page delivers verified package mapping (PLQP0064KB-A, 64-pin LFQFP), confirmed peripheral channel counts (6 MTU channels, 3 SCI, 1 RIIC, 1 RSPI), USB OTG support, and low-power mode timing (4.8 µs wake-up from software standby).
Technical Context
The R5F51115ADFM#YB2 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle 32×32-bit multiply. Its clock system includes independent ICLK/PCLK/FCLK domains, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and PLL input range (4–8 MHz).
Peripheral coordination is handled via Event Link Controller (ELC) - supporting 35 event types and direct module triggering without CPU intervention - and Data Transfer Controller (DTC) with chain transfer for interrupt-driven memory moves. The MCU supports IEC 60730 safety functions including CAC, IWDT, and RAM test assist.
