USB-C™ Power Delivery Controllers
The ubiquitous and interoperable USB port has evolved from its initial use as mainly a data interface and has become the primary means of charging mobile electronic devices. The USB-C standard further enhances the functionality of this port by being the port of connection for USB3.1 data transfers, up to 100W of power, and alternate modes like graphics, all through one single cable.
Microchip has variety of different solutions covering the new USB-C standard, as well as solutions for the standard USB Type-A connectors.
Microchip’s Bridge family of products combines an ultra-fast interface between a USB host and today’s most popular Flash media card formats including xD-Picture Card™ (xD), Memory Stick ® (MS), Secure Digital (SD) and MultiMediaCard™ (MMC) within a versatile, cost-effective and power-efficient multi-port Hi-Speed USB 2.0 hub controller. In addition, this family of products support the Hi-Speed Inter-Chip (HSIC) based USB 2.0 hub controller for applications that demand low power, small footprint and a reduced BOM without compromising performance or features.

USB Port Power Controllers
Microchip’s port power controllers provide a single USB port power switch capable of up to 2.5 Amps of continuous current as well as a USB 2.0 compliant data switch. When a portable device is plugged in, it can auto-cycle through up to seven preloaded charger emulation profiles until charging commences. The embedded profiles are compatible with BC1.2 CDP, DCP, YD/T-1591 as well as most Apple® and RIM® portable devices. It also allows portable device charging when an application or host is in standby or in a sleep state.

Fifth generation of highly integrated, full featured Hi-Speed USB 2.0 transceiver based on Microchip’s proven ULPI interface supports a wide variety of different reference clock frequencies, as well as accepting clocking from crystal/resonators and the ULPI 60 MHz clock-in mode. The family includes support for battery charging within traditional QFNs and very small formfactor, wafer-level chip scale packages (WLCSP). Eliminates the need for external VBus over-voltage protection ICs, USB switches, electrostatic discharge (ESD) protection devices, and reference oscillators, minimizing eBOM part count and conserving valuable board space.
Microchips’s portfolio of TrustSpan™ security products are designed to meet the increasing demand for flexible, custom security solutions targeting the PC, Peripheral and Embedded markets. Hi-Speed USB secure flash controller devices offer best-in-class data transfer performance with inline encryption for flash drives and portable devices. Hardware based inline encryption using the Advanced Encryption Standard (AES) provides world class security with no performance penalty. In addition, Microchip’s line of smart card reader controllers offer advanced subscriber, user or machine identity capabilities for host devices including notebook or desktop computers, monitors, docking stations, printers, and network access points.
USB is expected to be a preferred means to easily connect multiple displays to desktop and mobile PCs as well as to enable shared computing scenarios that are gaining popularity in classrooms. USB 3.0 or “SuperSpeed USB” offers a 10x data transfer speed increase and for the first time allows consumers to stream uncompressed high-definition content to their display via the USB port.
