Key Advantages

Low-power RL78 architecture helps extend battery life

Broad voltage range supports both low-voltage and 5 V systems

Rich serial interfaces including LIN for automotive and UART/I2C/CSI for industrial and consumer designs

Built-in safety and reliability features (POR, LVD, WDT) simplify robust system design

Good I/O density in a compact 10 x 10 mm footprint

Internal oscillator reduces external component count and simplifies BOM

Mature ecosystem and toolchain support for RL78, easing development and time to market

Packaging

Shipment format: Tape & Reel (TR) for automated assembly

Device package type: 64-LQFP (LFQFP)

Body size: 10 mm x 10 mm

Lead style and pitch: 64 gull-wing leads, typical 0.5 mm pitch

Material: Plastic epoxy molding compound with copper leadframe (typical for LQFP)

Mounting: Surface Mount, compatible with standard SMT reflow processes

Supplier device package: 64-LFQFP (10 x 10)

Thermal characteristics: -40°C to +85°C operating ambient; typical thermal performance for 64-LQFP depends on PCB and airflow. Refer to datasheet for exact thermal impedance values.

Electrical properties at a glance: 1.6–5.5 V supply, up to 32 MHz CPU clock, 48 I/O pins, 12-channel 8/10-bit ADC, internal oscillator, DMA/PWM/WDT/LVD/POR

Compliance: RoHS3 compliant

Lifecycle

Current status: Active. Not nearing discontinuation based on the RL78/G13 family roadmap.

Pin-compatible alternatives in the RL78/G13 family with the same 64-LQFP footprint are available with different Flash sizes and features. Examples include RL78/G13 parts in the R5F101xxDFB#X0 series (same package family) with 32KB, 48KB, 64KB, and 128KB Flash options.
