MIC2555-0YML-TR

The MIC2555 is a USB On-The-Go (OTG) transceiver designed to enable intelligent self-powered devices to communicate on a peer-to-peer basis with other USB and USB OTG enabled devices. Designed to perform as a PHY for USB Serial Interface Engines (SIE), MIC2555 is compatible with a wide variety of stand-alone OTG SIE chips, OTG IP cores (used in ASIC and COT designs), and Application Specific Standard Products (ASSPs). MIC2555 is fully compliant to USB-IF’s Universal Serial Bus Specification 2.0 and the On-The-Go Supplement Rev 1.0a, for Low speed and Full speed operation, and allows dual-role device (DRD) operation via an I2 C based controller interface. The controller’s robust register set permits full control over bus and interface activity for transacting Session Request Protocol (SRP) and Host Negation Protocol (HNP) sequences. Messaging between Host and Target devices can utilize either USB or UART signaling methods. Additionally, the MIC2555 permits audio signaling on its D+, D- and ID lines in support of analog car kit applications. USB communication is complemented with on-chip D+, Dpull-up/pull-down resistors, an integrated charge pump and low dropout voltage regulators to provide stable internal supply voltages and to supply VBUS power when operating as an A-device. Logic input levels spanning 1.6V to 4.5V ensure compatibility with current and future generations of process technology. The MIC2555 is offered in a space saving 4mm x 4mm 24-pin MLF® package.
