Renesas R5F5111JADFL#1A

Overview

R5F5111JADFL#1A 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 from 1.8–3.6 V across −40 to +85°C - deployed in industrial sensor nodes and low-power HMI controllers.

For engineers reviewing the R5F511JADFL#1A datasheet, R5F511JADFL#1A pinout, R5F511JADFL#1A application, or R5F511JADFL#1A equivalent, key selection criteria include USB OTG support with BC charging, 1.0 µs A/D conversion time, software standby current of 0.44 µA, and 64-pin LFQFP (PLQP0048KB-A) package compatibility for space-constrained designs.

Technical Context

The R5F511JADFL#1A implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its RX CPU core supports 64-bit accumulator operations and integrated 32-bit × 32-bit multiplier/divider for efficient signal processing.

On-chip peripherals include an Event Link Controller (ELC) for interrupt-free module triggering, Data Transfer Controller (DTC) supporting chain transfers, and independent watchdog timer (IWDT) driven by a dedicated 15 kHz oscillator - all optimized for deterministic real-time response in safety-aware embedded systems.

FAQ

What is the maximum operating frequency and CPU performance of the R5F511JADFL#1A?

The R5F511JADFL#1A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. This is achieved through its 32-bit RX CPU core with five-stage pipeline and single-cycle instruction execution. The R5F511JADFL#1A maintains this performance across its full 1.8–3.6 V supply range, with no wait states on flash access at full speed - making it suitable for real-time control tasks where deterministic timing is critical.

Does the R5F511JADFL#1A support USB On-The-Go (OTG) functionality?

Yes, the R5F511JADFL#1A integrates a USB 2.0 host/function module that fully supports OTG operation, including BC (Battery Charger) detection. It enables the R5F511JADFL#1A to act as either a USB host (e.g., connecting to flash drives) or a USB device (e.g., appearing as a CDC or HID class), with automatic role switching based on ID pin state. This eliminates the need for external USB switch ICs in dual-role applications.

What are the low-power consumption modes supported by the R5F511JADFL#1A?

The R5F511JADFL#1A supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it draws only 0.44 µA while retaining RAM content and enabling wake-up via RTC alarm or external interrupt - with a 4.8 µs recovery time. The R5F511JADFL#1A also features a module stop function and configurable operating power modes (high/middle/low-speed) to further optimize energy use per application demand.

How many analog-to-digital converter (A/D) channels does the R5F511JADFL#1A provide, and what is its conversion speed?

The R5F511JADFL#1A includes a 12-bit A/D converter with up to 14 input channels (AN000–AN015). Its minimum conversion time is 1.0 µs per channel when the ADCLK runs at 32 MHz. It supports scan modes (single, continuous, group), double-trigger mode for motor control redundancy, and multiple start sources including software, MTU timers, and external signals - all accessible without CPU intervention via the ELC.

What package type and pin count does the R5F511JADFL#1A use?

The R5F511JADFL#1A uses a 48-pin LFQFP package designated PLQP0048KB-A, measuring 7 × 7 mm with 0.5 mm pitch. This package provides 30 general-purpose I/O pins, 2 dedicated D/A outputs, and full peripheral signal access - balancing compactness, manufacturability, and routing flexibility. It is pin-compatible with other RX111 variants in the same 48-pin family, enabling scalable design reuse.
