Product details
Overview
R5F5111JADFK#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 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 to +85°C in a 64-pin LQFP (PLQP0064GA-A, 14 × 14 mm, 0.8 mm pitch) package - suited for compact industrial control and USB-connected sensor nodes.
For engineers reviewing the R5F5111JADFK#3A datasheet, R5F5111JADFK#3A pinout, R5F5111JADFK#3A application, or R5F5111JADFK#3A equivalent, key selection considerations include its 16 KB flash capacity, USB OTG support with BC (Battery Charger) compliance, 32 MHz high-speed on-chip oscillator (±1% accuracy), software standby mode (0.44 μA), and 46 general I/O pins with 5-V tolerance - all critical for low-power embedded designs requiring integrated connectivity and analog interface.
Technical Context
The R5F5111JADFK#3A implements a CISC Harvard-architecture RX CPU core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiplication. Its clock system includes independent ICLK/PCLK/FCLK domains, PLL input range of 4–8 MHz, and dedicated 15 kHz IWDT oscillator.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables direct module-to-module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers activated by 82 interrupt sources - enabling deterministic real-time response in motor control and USB data streaming applications.
