Packaging

Type: 64-LQFP (Low-Profile Quad Flat Package)

Body size: 10 x 10 mm; low profile thickness (approx. 1.4 mm typical)

Lead pitch: typically 0.5 mm for LQFP-64 (check datasheet for exact)

Material: epoxy-molded plastic, copper alloy leadframe, lead-free matte tin plating (RoHS3)

Pin configuration: 64 pins total, 52 user GPIO; dedicated power pins (VDD/VDDA), grounds (VSS/VSSA), and peripheral pins for CAN, USB, SPI, I2C, UART/USART

Tape & Reel: TR suffix indicates T&R for automated assembly; ideal for high-volume SMT lines

Mounting: Surface Mount Technology (SMT)

Thermal characteristics: ambient -40°C to +105°C; typical thermal resistance depends on PCB (refer to datasheet for θJA/θJC and thermal guidelines)

Electrical properties: VDD 2.0–3.6 V; internal clocks; many I/O pins are 5V tolerant (verify pin list in datasheet); ESD and moisture sensitivity per LQFP norms (MSL typically level 3—check datasheet/label)

Lifecycle

Current status: Active in mass production as of latest public information; not near discontinuation based on typical availability. Supply can vary—contact Y-IC for up-to-date stock and lead time.
