Product details
Overview
R5F5111JADNE#2A 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), USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and operates across −40 to +85°C in a 48-pin HWQFN package (7 × 7 mm, 0.5 mm pitch). It targets low-power embedded control in industrial sensors and USB-connected edge devices.
For engineers reviewing the R5F5111JADNE#2A datasheet, R5F5111JADNE#2A pinout, R5F5111JADNE#2A application, or R5F5111JADNE#2A equivalent, key selection considerations include its 16 KB flash capacity, USB OTG support with BC (Battery Charger) compliance, 48-pin HWQFN footprint, −40 to +85°C temperature grade, and integrated 12-bit ADC with double-trigger capability for motor sensing.
Technical Context
The R5F5111JADNE#2A implements the RXv1 CPU core with CISC Harvard architecture, five-stage pipeline, and variable-length instructions enabling ultra-compact code. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and CAC for frequency accuracy validation - all configurable per ICLK, PCLK, and FCLK domains.
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 MCU supports IEC 60730 Class B functional safety via IWDT, CAC, and RAM test assist functions.

FAQ
What is the maximum operating frequency and CPU performance of the R5F5111JADNE#2A?
The R5F5111JADNE#2A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. This is achieved using the 32-bit RXv1 CPU core with a five-stage pipeline and single-cycle instruction execution for most operations. Its performance is validated across the full −40 to +85°C temperature range and 1.8–3.6 V supply.
Does the R5F5111JADNE#2A support USB On-The-Go (OTG) and Battery Charging (BC) specifications?
Yes, the R5F5111JADNE#2A integrates a USB 2.0 full-speed host/function/OTG module compliant with USB BC 1.2. It supports detection of SDP, CDP, and DCP port types via D+/D− line analysis and includes dedicated hardware signals (USB0_ID, USB0_VBUS, USB0_OVRCURA/B) required for robust OTG operation in portable and embedded designs.
What analog peripherals are included in the R5F5111JADNE#2A and how are they configured?
The R5F5111JADNE#2A includes a 12-bit A/D converter with up to 14 input channels (AN000–AN015), an 8-bit D/A converter with two outputs (DA0, DA1), and an integrated temperature sensor. The ADC supports scan modes, double-trigger for motor control, and external start triggers; the DAC outputs 0 V to VCC and is available only in 48-pin and larger packages like the R5F5111JADNE#2A.
How does the Event Link Controller (ELC) enhance real-time responsiveness in the R5F5111JADNE#2A?
The ELC in the R5F5111JADNE#2A enables direct hardware-level linking between 35 event sources (e.g., timer overflows, GPIO edges, ADC completions) and peripheral modules (e.g., MTU2, DTC, SCI), bypassing CPU interrupts. This reduces latency to one cycle, allows peripheral coordination during CPU sleep, and eliminates software overhead for time-critical signal chains.
What low-power modes and wake-up capabilities does the R5F5111JADNE#2A offer?
The R5F5111JADNE#2A supports three low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby, it draws just 0.44 µA while retaining RAM and register contents, with wake-up in 4.8 µs via external interrupt, RTC alarm, or USB activity. The high-speed on-chip oscillator (32 MHz) and IWDT operate independently to maintain timing integrity during low-power states.
