Key Advantages

Low power architecture enables battery and energy-sensitive designs

Wide voltage range simplifies power supply design and supports 5 V systems

Rich peripheral set reduces external components and cost

Hardware safety features (WDT, LVD, POR) improve reliability

Internal oscillator cuts BOM and accelerates design

Mature RL78/G13 platform with broad toolchain and community support

Compact 7x7 mm 48-LFQFP fits space-constrained boards

Strong serial connectivity options for industrial and automotive networks (LIN, UART, I2C, SPI)

Packaging

Type: 48-LFQFP (Low-profile Fine-pitch Quad Flat Package), 7 x 7 mm body

Material: Molded epoxy resin body with copper alloy leads, tin plating (typical for LFQFP)

Size: 7 mm x 7 mm nominal body; low-profile height (LQFP standard)

Pin configuration: 48 leads around four sides; 34 GPIO available; dedicated pins for VCC, GND, reset, oscillator, serial interfaces

Lead pitch: standard fine-pitch for LQFP-48 (commonly 0.5 mm)

Thermal characteristics: operates -40°C to 105°C; thermal performance depends on PCB layout; use solid ground planes and thermal vias to improve heat spreading

Electrical properties: 2.4 V to 5.5 V supply; internal oscillator; 10-bit ADC; peripheral protection features (LVD, POR)

Mounting: Surface-mount (SMT)

Supplier device package: 48-LFQFP (7x7)

Factory packaging: Tray

Lifecycle

Current status: Active production in the Renesas RL78/G13 family; not near discontinuation based on publicly available family status

Equivalents or alternatives: Pin-compatible and functionally similar options exist within the RL78/G13 family with different Flash sizes and packages (e.g., other R5F100Gxx variants in 48-LQFP, or RL78/G14 for more performance/features). Exact pinand option-compatible cross-references depend on specific peripheral options and option bytes.
