Product details
Overview
R5F5111JADFK#5A 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 64-pin LQFP (PLQP0064GA-A, 14 × 14 mm, 0.8 mm pitch) package - used in industrial sensor nodes and low-power USB-connected edge devices.
For engineers reviewing the R5F511JADFK#5A datasheet, R5F511JADFK#5A pinout, R5F511JADFK#5A application, or R5F511JADFK#5A equivalent, this page delivers verified specifications, validated package mapping, confirmed peripheral channel counts per package variant, real-world use-case context, and two technically documented alternative parts for design flexibility.
Technical Context
The R5F511JADFK#5A implements the RXv1 CPU core with Harvard architecture, five-stage pipeline, and variable-length instructions enabling ultra-compact code. It supports little-endian data and instruction layout, includes a 64-bit accumulator for single-cycle 32×32 multiply-accumulate, and features on-chip debugging via FINE interface.
Its clock system combines high-speed (32 MHz ±1%) and low-speed (15 kHz IWDT-dedicated) on-chip oscillators, PLL, sub-clock (32.768 kHz), and external crystal support (up to 20 MHz). Power management includes software standby mode (0.44 μA) with 4.8 μs wake-up and three configurable low-power modes synchronized to ICLK/PCLK/FCLK domains.

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 package: 64-pin LFQFP (PLQP0064KB-A, 10 × 10 mm, 0.5 mm pitch) vs. LQFP (14 × 14 mm, 0.8 mm pitch) | Higher PCB density possible with smaller footprint; thermal resistance slightly higher due to reduced pad area | Select R5F511JADFM#3A when board space is constrained and thermal margin allows; same firmware and pin compatibility |
| R5F5111JADFL#3A | Identical silicon but in 48-pin LFQFP (PLQP0048KB-A, 7 × 7 mm); reduces I/O count (30 vs. 46 GPIO), removes DA0/DA1, and limits A/D to 10 channels | Suitable for cost-sensitive, lower-peripheral-count designs where USB and RTC remain essential | Choose R5F511JADFL#3A for simplified BOM and smaller form factor where analog output and full A/D channel count are non-critical |
Compared with R5F511JADFK#5A, the R5F511JADFM#3A offers identical functionality in a denser package for space-constrained layouts, while R5F511JADFL#3A trades I/O and analog resources for lower cost and footprint - both retain full USB 2.0, RTC, and safety features required for certified embedded control.

FAQ
What is the maximum operating frequency and power supply range for the R5F511JADFK#5A?
The R5F511JADFK#5A operates at up to 32 MHz when powered from 2.7–3.6 V, delivering 50 DMIPS. At 2.4–2.7 V, max frequency drops to 16 MHz; at 1.8–2.4 V, it is limited to 8 MHz. Supply current is 3.2 mA typical at 32 MHz, and the device supports three low-power modes including software standby at 0.44 μA - all verified in the R01DS0190EJ0130 datasheet.
Does the R5F511JADFK#5A include USB functionality, and what modes does it support?
Yes, the R5F511JADFK#5A integrates a USB 2.0 host/function/OTG module compliant with full-speed (12 Mbps) and low-speed (1.5 Mbps) operation. It supports isochronous transfers and Battery Charger (BC) v1.2 detection. The R5F511JADFK#5A uses internal transceivers - no external PHY required - and supports device, host, and On-The-Go roles with single-port implementation.
How many A/D and D/A channels does the R5F511JADFK#5A provide, and what are their resolutions?
The R5F511JADFK#5A includes one 12-bit successive-approximation A/D converter with up to 14 input channels (AN000–AN015), achieving 1.0 μs minimum conversion time at 32 MHz ADCLK. It also provides two 8-bit D/A converter channels (DA0 and DA1), each delivering 0–VCC analog output - both features are confirmed active in the 64-pin LQFP package per Table 1.2 of the datasheet.
Is the R5F511JADFK#5A qualified for industrial temperature operation?
Yes, the R5F511JADFK#5A is rated for −40 to +85°C operation (D-grade), matching the industrial temperature specification. This is explicitly stated in Table 1.3 of the R01DS0190EJ0130 datasheet under "Operating Temperature" for all R5F5111JADxx variants, including R5F511JADFK#5A. No derating is required within this range.
What debug interface does the R5F511JADFK#5A support, and is external hardware required?
The R5F511JADFK#5A supports on-chip debugging via the FINE interface using the Renesas E1 emulator. The FINED pin (pin 41 in PLQP0064GA-A) provides bidirectional debug communication. No external debug probe is mandatory for basic programming - serial bootloader via SCI or USB DFU is also supported - but full real-time trace and breakpoint debugging require the E1 or compatible tool.
