Product details
Overview
R5F5111JADLF#UA 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°C to +85°C in a 64-pin WFLGA (5 × 5 mm, 0.5 mm pitch) package - suited for compact industrial sensor nodes and USB-connected embedded control.
For engineers reviewing the R5F5111JADLF#UA datasheet, R5F5111JADLF#UA pinout, R5F5111JADLF#UA application, or R5F5111JADLF#UA equivalent, key selection considerations include its 64-pin WFLGA footprint, USB OTG capability with VBUS monitoring, 1.0 µs A/D conversion time, software standby mode (0.44 µA), and integrated event link controller for low-power peripheral coordination without CPU wake-up.
Technical Context
The R5F5111JADLF#UA implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. 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 configurable ICLK/PCLK/FCLK domains.
Peripheral integration centers on low-power autonomy: Event Link Controller (ELC) enables direct module-to-module triggering (e.g., MTU timer → A/D start), Data Transfer Controller (DTC) supports chain transfers on 82 interrupt sources, and the Realtime Clock provides calendar mode with software-standby wake-up - all while maintaining 4.8 µs recovery from software standby mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F5111JADFM#3A | Same core, memory, and peripherals; differs only in 64-pin LFQFP (10×10 mm, 0.5 mm pitch) package instead of WFLGA | Preferred where manual soldering, prototyping, or legacy PCB layout compatibility is required | Select for through-hole or reflow-friendly QFP assembly; avoid if board space < 25 mm² is constrained |
| R5F5111JADFL#3A | Identical functionality but in 48-pin LFQFP (7×7 mm, 0.5 mm pitch); reduced I/O count (30 vs. 46), no D/A, no USB OTG ID pin | Suitable for cost-sensitive, non-USB applications requiring fewer analog/digital resources | Choose when USB host/OTG and dual DAC are unnecessary; saves ~$0.30/unit and simplifies layout |
Compared with R5F5111JADLF#UA, the LFQFP variant offers easier prototyping but larger footprint, while the 48-pin version trades USB OTG and DAC capability for lower cost and density - making R5F5111JADLF#UA optimal for space-constrained, USB-enabled edge devices requiring analog I/O.

FAQ
What is the maximum operating frequency and CPU performance of the R5F5111JADLF#UA?
The R5F5111JADLF#UA operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its RX CPU core features a five-stage pipeline, variable-length instruction set, and 64-bit accumulator enabling single-cycle 32×32 multiply-accumulate operations - verified in Renesas R01DS0190EJ0130 Rev.1.30 Section 1.1.
Does the R5F5111JADLF#UA support USB On-The-Go (OTG) functionality?
Yes, the R5F5111JADLF#UA integrates a USB 2.0 host/function module supporting OTG mode, including VBUS monitoring (USB0_VBUS), ID pin detection (USB0_ID), and BC 1.2 battery charger recognition. This enables dynamic role switching between host and device - confirmed in Section 1.1 "Communication functions" and Table 1.1 of R01DS0190EJ0130.
What are the memory resources available on the R5F5111JADLF#UA?
The R5F5111JADLF#UA includes 16 KB of on-chip flash memory (executed at full 32 MHz with zero wait states), 8 KB of SRAM, and 8 KB of data flash rated for 1,000,000 erase/write cycles. All memory blocks operate without wait states at maximum CPU speed - as specified in Table 1.1 and Section 1.1 "Memory" of R01DS0190EJ0130.
What low-power modes does the R5F5111JADLF#UA support, and what is its lowest current consumption?
The R5F5111JADLF#UA supports three low-power modes, with software standby mode consuming just 0.44 µA (typ.) while retaining RTC operation and enabling wake-up via external interrupt, sub-clock alarm, or USB VBUS detection. Recovery time from this mode is 4.8 µs - detailed in Section 1.1 "Low power consumption functions" of R01DS0190EJ0130.
Is the R5F5111JADLF#UA pin-compatible with other members of the RX111 Group?
No - the R5F5111JADLF#UA uses the 64-pin WFLGA (PWLG0064KA-A) package, which is not pin-compatible with RX111 variants in LFQFP (PLQP0064KB-A) or LQFP (PLQP0064GA-A) packages due to differing pad layouts and thermal pad presence. Pin mapping must be verified per Figure 1.4 and Table 1.4 of R01DS0190EJ0130.
