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).
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 I
2C 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+, D-
pull-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. Data sheets
and support
documentation can be found on Micrel’s web site at
www.micrel.com.
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.
