Product details
Overview
R5F5111JADNF#2A from Renesas is a 32-bit RX CPU core 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 from 1.8–3.6 V across −40 to +85°C - deployed in industrial sensor nodes and USB-connected edge devices.
For engineers reviewing the R5F5111JADNF#2A datasheet, R5F5111JADNF#2A pinout, R5F5111JADNF#2A application, or R5F5111JADNF#2A equivalent, key selection criteria include its 40-pin HWQFN (PWQN0040KC-A) package, USB OTG support with BC charging, low-power software standby mode (0.44 μA), and integrated event link controller for interrupt-free peripheral coordination.
Technical Context
The R5F5111JADNF#2A 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), all managed via independent ICLK/PCLK/FCLK domains.
Peripheral coordination is handled by the Event Link Controller (ELC), which routes 35 event signals directly between modules without CPU intervention - enabling timer-triggered ADC conversions, port output enable control, and RTC wake-up from software standby mode while the CPU remains asleep.

Yes, the R5F5111JADNF#2A integrates a USB 2.0 full-speed host/function/OTG module compliant with USB BC 1.2. It supports dual-role operation, isochronous transfers, and includes dedicated VBUS monitoring (USB0_VBUS), ID detection (USB0_ID), and overcurrent protection inputs (USB0_OVRCURA/B).
What are the low-power capabilities of the R5F5111JADNF#2A, and how fast is wake-up from standby?
The R5F5111JADNF#2A offers three low-power modes, including software standby mode drawing just 0.44 μA. Recovery from this mode takes only 4.8 μs - enabling rapid responsiveness to USB events, RTC alarms, or external interrupts while maintaining ultra-low energy consumption in battery-powered deployments.
How many analog and digital I/O resources does the R5F5111JADNF#2A provide in its 40-pin HWQFN package?
In the PWQN0040KC-A 40-pin HWQFN package, the R5F5111JADNF#2A provides 24 general-purpose I/O pins, 14 channels for its 12-bit A/D converter (AN000–AN015), and 2 channels for its 8-bit D/A converter (DA0, DA1).

Is the R5F5111JADNF#2A pin-compatible with other members of the RX111 Group?
No - the R5F5111JADNF#2A uses the 40-pin HWQFN (PWQN0040KC-A) package, while other RX111 variants use 36-, 48-, or 64-pin packages (e.g., PWLG0036KA-A, PLQP0048KB-A, PLQP0064KB-A). Pin compatibility exists only within the same package variant family; cross-package migration requires PCB redesign and I/O remapping.
