General Description

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).

Features

• Complies with USB-IF USB standard 2.0 and OTG supplement Revision 1.0a.

• Provides signaling and control logic for SRP and HNP, enabling USB Dual-role device operation.

• Designed for Full-speed and Low-speed USB communications.

• I2C controller interface.

• Offers 3 modes of operation:

- USB

- UART

- Audio

• Operates with VLOGIC of 1.6V – 4.5V, assuring compatibility with low voltage ASICs.

• Tri-level ID detection for recognition of USB and non-USB devices.

• Supports USB /Car Kit audio interface.

• Allows Single-ended and Differential Logic I/O.

• Integrated charge pump for VBUS supply.

• On-chip pull-up, pull-down resistors minimize external component count.

• Suspend and Power-down modes for power conservation.

• Operates over the full Industrial Temperature range: –40°C to +85°C.
