RoHS3 compliant

Key Advantages

Balanced performance and power at 20 MHz with 2.0–3.6 V supply

Rich analog integration reduces external components and BOM cost

Many I/O pins (83) in a compact 100-pin LQFP for flexible board layout

External bus interface allows memory or peripheral expansion

Industrial temperature range for harsh environments

Mature, proven V850ES architecture for long-term reliability

Internal oscillator simplifies clock tree and lowers cost

Packaging

Package type: 100-LQFP (also called 100-LFQFP)

Material: Plastic epoxy mold compound with tin-plated leads

Body size: 14 mm x 14 mm, low-profile

Thickness: approximately 1.4 mm (typical for LQFP)

Lead count: 100 pins, fine pitch (typically 0.5 mm for LQFP-100)

Pin configuration: 4-sided gull-wing leads, standard LQFP pinout for V850ES/JG3-L

Mounting: Surface-mount

Thermal characteristics: Operates -40°C to +85°C; actual thermal resistance depends on PCB copper, airflow, and layout; no exposed thermal pad (standard LQFP)

Electrical properties tied to package: 2.0–3.6 V supply, internal oscillator, I/O count 83; consult datasheet for pin-level drive, clamp currents, and ESD

Packaging format: Tray for manufacturing convenience

Compliance: RoHS3

Moisture sensitivity: Refer to datasheet for MSL handling recommendations

Lifecycle

Status: The V850ES/JG3-L family is mature. Availability can vary by region and time. Please check current status before committing to new designs.

Equivalents or alternatives: Exact drop-in pin-compatible replacements may be limited. Migration paths often include Renesas RX, RA, and RL78 families depending on performance and architecture needs. Popular 32-bit alternatives in 100-pin LQFP include Renesas RX and RA devices (for example RX130/RX231, RA4M2/RA4M3), but they are not pin-compatible and require redesign.

Recommendation: If you need exact equivalents or verified cross-references, contact our sales team via the Y-IC website. We will provide a detailed, application-specific cross list and migration guidance.
