Serial connectivity: CSI/SPI-like, I2C, LIN, UART/USART

A/D converter: 12 channels, selectable 8/10-bit resolution

Internal oscillator for compact designs (no external clock required)

Wide supply voltage: 1.6–5.5 V

Industrial temperature grade: -40°C to +85°C (TA)

RL78/G13 series ecosystem with mature tools and libraries

RoHS3 compliant

Key Advantages

Very low power RL78 architecture for battery and energy-sensitive products

Wide voltage range enables operation from low-voltage supplies and 5 V systems

Integrated safety features (LVD, POR, WDT) improve reliability and system uptime

Rich peripheral mix reduces external components and cuts BOM cost

Internal oscillator simplifies design and saves board space

Multiple serial interfaces support straightforward system integration (sensors, comm modules, LIN nodes)

Stable, long-lived Renesas platform with strong toolchain and community support

Pin-count and memory scalability within RL78 families for easy reuse and upgrade

Packaging

Type: 64-LQFP / 64-LFQFP (Lead Frame Quad Flat Package)

Body size: 10 x 10 mm

Height: low-profile QFP (typical ~1.4 mm; check datasheet for exact dimension)

Pin count and pitch: 64 leads, typical 0.5 mm pitch

Pin configuration: quad-sided gull-wing leads; 48 general-purpose I/O available from total pin set

Material: epoxy mold compound, copper leadframe

Lead finish: matte tin (Pb-free), RoHS3 compliant

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

Shipment form: Tray

Thermal characteristics: LQFP packages show board-dependent thermal resistance; typical ThetaJA is high for QFP vs QFN/BGA. Use good copper area and thermal vias; verify exact ThetaJA/ThetaJC in the datasheet

Electrical properties (package-related): supports standard leaded SMT reflow profiles; observe moisture sensitivity labeling (LQFP is commonly MSL 3; confirm on product label/datasheet)

Mounting: Surface Mount; follow Renesas reflow and land pattern guidelines

Lifecycle

Status: Active production; not nearing discontinuation based on current RL78/G13 family status

Equivalent/alternative models:

- Pin-compatible RL78/G13 devices in the R5F101 family with different Flash sizes (e.g., 32KB, 48KB, 96KB, 128KB) in the same 64-LQFP footprint

- Higher-performance upgrade path: RL78/G14 family (R5F104 series) in similar pin counts with enhanced peripherals

- ARM-based migration option: Renesas RA2 series (e.g., RA2E1/RA2A1) for 32-bit performance while retaining low power

- For exact orderable part numbers and drop-in, pin-compatible alternatives, contact our sales team via the Y-IC website for a curated cross-reference list

If you need a fully equivalent replacement (same pinout, same package, same voltage range), we will match it from the RL78/G13 lineup. Reach out to our sales team for model-by-model guidance
