LIF-UC140-CM81I

Specialized Overview

The LIF-UC140-CM81I is a specialized integrated circuit designed for USB Type-C Cable Detect (CD) and Power Delivery (PD) applications in hosts and devices. It features an ultra-small form factor of 4.00 mm x 4.00 mm within an 81-ball ucBGA package with a 0.40 mm pitch. The device operates on a core supply voltage (VCC) ranging from 1.14 V to 1.26 V and supports I/O voltages between 1.71 V and 3.46 V. It provides logic-based PHY capabilities, including BMC encoding/decoding, CRC calculation, and 4B5B encoding/decoding for reliable communication. The component includes a flexible 8-bit microcontroller policy engine and supports USB PD Specification v2.0.
