Pin configuration: 80 leads, 68 user I/O; mapped for CAN/LIN/SPI/UART/CSI/IC, ADC channels, power and ground pins; refer to datasheet pinout

Mounting: Standard SMT reflow; JEDEC LQFP land pattern

Thermal characteristics: Wide ambient operation (-40°C to +125°C). Use solid ground plane and adequate copper for heat spreading; consult datasheet for thermal impedance guidance

Electrical properties: 2.7V to 5.5V supply, 24 MHz max clock, internal oscillator, 22x10-bit SAR ADC, integrated LVD/POR/WDT and PWM outputs

Supplier device package: 80-LFQFP (12x12)

Shipping package: Tray

Lifecycle

Status: Active and in production as part of the RL78/F13 family (not nearing discontinuation based on current RL78 portfolio trends)

Pin-compatible and functional alternatives:

- RL78/F13 family variants in 80-LQFP with different Flash sizes (e.g., lower or higher memory options) for cost or capacity optimization

- RL78/F14 series (superset) in 80-LQFP offering extended peripheral sets and similar pinouts for design scalability

- RL78/G13 series in 80-LQFP for applications that do not require CAN/LIN (similar core and many shared peripherals)

Note: Exact drop-in part numbers depend on required Flash/RAM/EEPROM size, CAN/LIN needs, and pin function mapping. Contact our sales team via the Y-IC website for a precise cross and verified pin-compatibility list
