Product details
Overview
R5F5111JADFM#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 16 KB on-chip flash, 8 KB SRAM, and 8 KB data flash. It integrates a 12-bit A/D converter (14 channels, 1.0 µs conversion), USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and operates across −40 to +85°C in industrial applications such as sensor gateways and USB-connected edge controllers.
For engineers reviewing the R5F5111JADFM#3A datasheet, R5F5111JADFM#3A pinout, R5F5111JADFM#3A application, or R5F5111JADFM#3A equivalent, key selection criteria include its 64-pin LFQFP (PLQP0064KB-A) package, USB OTG support with BC compliance, low-power software standby mode (0.44 µA), and IEC 60730-ready safety functions including CAC and IWDT.
Technical Context
The R5F5111JADFM#3A 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 high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz), with independent ICLK/PCLK/FCLK domains for precise peripheral timing control.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables direct module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers triggered by 35+ event sources. The MTU2 timer unit provides six 16-bit channels with complementary PWM, phase counting, and A/D trigger generation - critical for motor control and real-time signal processing.
