2.1 Introduction
PHYTEC phyCORE-OMAP44xx Carrier Boards are fully equipped with all mechanical and electrical components
necessary for the speedy and secure start-up and subsequent communication to and programming of applicable
PHYTEC System on Module (SOM) modules. phyCORE-OMAP44xx Carrier Boards are designed for evaluation,
testing and prototyping of PHYTEC System on Modules in laboratory environments prior to their use in customer
designed applications.
The phyCORE-OMAP44xx Carrier Board provides a flexible development platform enabling quick and easy
start-up and subsequent programming of the phyCORE-OMAP44xx System on Module. The carrier board design
allows easy connection of additional expansion boards featuring various functions that support fast and
convenient prototyping and software evaluation.
The phyCORE-OMAP44xx Carrier Board supports the following features for the phyCORE-OMAP44xx modules:
•
Power supply circuits to supply the phyCORE-OMAP44xx and the peripheral devices of the carrier board
•
Power over Ethernet (PoE)
•
Full featured 4 line RS-232 transceiver supporting UART2 of the phyCORE-OMAP44xx with data rates of up
to 120 kbps, hardware handshake and RS-232 connector
•
Second RS-232 connector providing the signals of the RS-232 transceiver on the phyCORE-OMAP44xx and
thus allowing communication via UART3 of the OMAP44xx at RS-232 level
•
Four USB Host interfaces available at a standard USB A connector, as well as at the display and PEB
connectors
•
USB OTG interface brought out to a standard USB Mini-AB connector
•
10/100 Mbps Ethernet interface with Power over Ethernet
•
Complete Audio interface available at three 3.5 mm audio jacks
•
Phytec Display Interface (PDI) (LVDS display interface with separate connectors for data lines and display /
backlight supply voltage) supporting either the Display Serial Interface (DSI), or the parallel display
interface of the OMAP44xx
•
Circuitry to allow dimming of a backlight
•
Touchscreen interface for use of 4 wire resistive touch screens
•
Two parallel camera interface connectors compatible to PHYTEC's phyCAM-P camera interface standard
including an I
2
C bus for camera control. One connector providing connectivity to the secondary camera
interface (CSI2-B/CSI22) of the OMAP44xx for 8-bit-wide camera signals. Second connector to connect to
the parallel camera interface of the OMAP4460 which supports selection between 8-bit and 10-bit-wide data
signals
•
Additional 30-pin pin header row for development purposes, connecting to the parallel camera interface of
the OMAP4460
•
Two Secure Digital Memory / MultiMedia Card slots
•
Two extension connectors for customer prototyping purposes. Both compatible with PHYTEC's extension
board (PEB) interface standard featuring one USB, one I
2
C and one SPI interface, as well as one GPIO/IRQ
at either connector
•
DIP-Switch to configure the boot options for the phyCORE-OMAP44xx module
•
Holder for backup battery to keep alive the real-time clock and other secure registers of the PMIC on the
phyCORE-OMAP44xx
