Key Features

2 independent UART channels (DUART)

Integrated printer port for legacy parallel interfaces

16-byte FIFOs to cut CPU overhead and improve throughput

Programmable baud rate up to 1 Mbps

Modem control support for robust handshaking

False start-bit detection to avoid framing errors

68-PLCC J-lead package for sturdy SMT assembly

RoHS3 compliant, lead-free G4 finish

Factory Tape & Reel option for automated pick-and-place

Key Advantages

Combines two UARTs and a printer port in one device, reducing BOM and board area

Higher serial performance with FIFOs that smooth data bursts

Better link stability via false start detection and modem control

5 V TTL-compatible I/O for legacy and industrial systems

Mature, proven solution with stable supply and broad ecosystem support

Multiple ordering options within the family for manufacturing flexibility

Packaging

Shipment format: Tape & Reel (TR)

Device package: 68-PLCC (Plastic Leaded Chip Carrier), J-lead LCC

Body size: 24.23 mm x 24.23 mm (typical for 68-PLCC)

Mounting type: Surface mount with perimeter J-leads

Pin count and configuration: 68 pins, J-leads on all four sides

Material and compliance: Plastic encapsulated PLCC body, lead-free G4 finish, RoHS3 compliant

Thermal characteristics: PLCC package supports standard convection cooling; for exact thermal resistance (thetaJA/thetaJC) and power dissipation limits, use the datasheet and follow good PCB copper area and airflow practices

Electrical properties (high level): 4.75–5.25 V supply, 1 Mbps max data rate, 16-byte FIFOs, modem control, false start-bit detection
