Key Advantages

Small footprint 4x4 mm VFBGA saves board space in dense designs

Wide 1.6–5.5 V supply range fits battery-powered and 5 V systems without level shifting

Low-power RL78 architecture helps extend battery life

Integrated peripherals reduce external components and BOM cost

Internal oscillator simplifies design and cuts clock component cost

DMA boosts data movement efficiency and frees CPU time

Robust communication options for mixed-protocol systems, including LIN for automotive body electronics

96KB Flash and 8KB RAM provide a balanced memory size for many mid-range applications

Proven RL78/G13 ecosystem and tooling lower development risk

Packaging

Type 64-VFBGA Very Fine Pitch Ball Grid Array

Body size approximately 4 x 4 mm

Ball count 64 total balls

Pin configuration 48 GPIO plus power, ground, and dedicated function pins as defined in the datasheet

Material lead-free, RoHS3-compliant BGA construction; standard industry substrate and mold compounds (see datasheet for exact details)

Mounting surface-mount compatible with standard BGA assembly processes

Thermal characteristics ambient operating range -40°C to +85°C; thermal performance depends on PCB copper area and vias; follow Renesas layout guidance for heat spreading

Electrical properties supply 1.6–5.5 V, up to 32 MHz system clock, internal oscillator, on-chip 12-channel 10-bit ADC, integrated LVD/POR/PWM/WDT, multiple serial interfaces

Lifecycle

Current status generally active within the RL78/G13 family based on publicly available information

Not flagged as nearing discontinuation in typical channel checks

Equivalent or alternative models availability depends on required package, pinout, and memory size. Pin-compatible RL78/G13 devices are available across different densities and packages such as LQFP/QFP options. For an exact, vetted cross-reference list (same pinout, same memory, same peripherals), please contact our sales team via the Y-IC website. We will help you select drop-in or near-drop-in alternatives, including other RL78/G13 variants and RL78/G14 devices if you need extended features.
