Memory & I/O Mapping - Mistral OMAP35 Series Hardware User's Manual

The EVM supports three UART (UART 1, 2 and 3) interfaces via two serial ports on
the main board.
High Speed USB OTG interface is supported on the EVM Main Board via an
onboard external USB transceiver ISP 1507 from NXP.
High Speed USB HOST (USB2) interface is supported on the EVM Main Board via
an onboard external USB transceiver USB3320 from SMSC.
One Stereo Line IN and Stereo Headset OUT audio interface is supported through
the audio codec on the TPS65950 device. The audio codec on the power module is
controlled by internal registers that can be accessed through high-speed I2C
interface.
The EVM includes 11 status LEDs, 2 user DIP switches and 16 push button
switches.
It supports the standard 14-pin JTAG and ETM debug interfaces. The EVM is
designed to work with TI's Code Composer Studio development, or standard GDB
tool environments. For more details refer Getting Start Guide.
The EVM is powered by a +5V external power supply. The TPS65950 power
management device provides the required CPU core voltages and IO voltages.
The EVM can also be powered using an external Lithium Ion/Polymer battery.
(Battery not supplied with EVM). RTC is supported through a coin cell.
