Key Advantages

Low power 32-bit performance with wide supply range for battery-powered and USB-powered designs

Integrated USB OTG simplifies direct PC or device-to-device connectivity without external controllers

On-chip data Flash enables frequent nonvolatile data logging without external EEPROM

Rich analog set with 12-bit ADC and 8-bit DACs reduces external components

Mature RX111 ecosystem with proven tools, application notes, and software support lowers development risk

Industrial temperature operation supports harsh environments

Cost-effective small Flash configuration suited to compact control tasks and USB device endpoints

Packaging

Package type: 64-LFQFP, low-profile quad flat package, 10 x 10 mm body

Lead pitch and count: 64 leads, typically 0.5 mm pitch (verify in datasheet)

Materials: Epoxy molding compound body, copper alloy lead frame, matte tin plated leads (industry standard for RoHS QFP)

Mounting: Surface mount, reflow solder compatible

Supplier device package: 64-LFQFP 10x10

Shipping form: Tray

Pin configuration: 64 pins arranged on four sides; multiple VDD/VSS pins distributed for stable power; dedicated pins for USB, analog, and clocks per datasheet

Thermal characteristics: Operates from -40°C to +85°C ambient; thermal performance depends on PCB copper area and airflow; follow datasheet PCB layout and thermal guidelines for best heat spreading

Electrical properties summary: 1.8 V to 3.6 V supply range; on-chip regulators and brownout/LVD; I/O counts and peripheral pin multiplexing defined by RX111 pin function tables

Lifecycle

Status: Active in production as part of the Renesas RX111 family based on current public information

Not nearing discontinuation based on typical RX family longevity; always confirm latest status with Y-IC

Pin-to-pin or function-close alternatives

- RX111 family options with larger Flash and RAM in the same 64-LQFP footprint may be available for upward scalability

- RX113 family devices offer similar CPU and peripherals with added features such as capacitive touch and may provide drop-in or near drop-in options depending on package and pinout

- Other memory and package variants within the R5F5111J base product number line may exist with different temperature grades or ROM/RAM sizes

Important note: Exact pin compatibility and peripheral equivalence vary by suffix and memory option.
