Integrated LCD driver reduces BOM and board space for display applications

Rich serial interfaces support legacy and modern protocols (LIN, IrDA, UART, I2C, CSI)

Robust reliability with LVD, POR, WDT and industrial temperature rating

Mature ecosystem and long-term support from Renesas

Packaging

Type: 80-LQFP, surface-mount, thin profile

Body size: 12 mm x 12 mm nominal

Pin count and pitch: 80 leads, pitch typically 0.5 mm

Material: Copper leadframe, epoxy molding compound, lead-free matte tin plating (RoHS3)

Supplier device package: 80-LQFP (12x12)

Shipping form: Tray

Pin configuration: 80 pins including multiple VDD/VSS, analog inputs for ADC, serial interfaces (CSI, I2C, UART/USART), LIN, LCD segment/common pins, and GPIO; see datasheet pinout for exact mapping

Thermal characteristics: No exposed pad; thermal performance depends on PCB copper area and airflow. Follow datasheet guidelines for θJA and board design to manage junction temperature

Electrical properties: 1.7V–5.5V supply, internal oscillator available, integrated LVD, ESD protection structures typical of RL78; consult datasheet for detailed current consumption, drive strength, and timing

Lifecycle

Status: Active and in ongoing production based on the RL78/I1C family profile

Not nearing discontinuation at this time

Alternatives and equivalents:

- Close alternatives exist within the RL78/I1C family with different memory sizes and packages
