2.0 The eZdspTM F2808 Operation

This chapter describes the eZdspTM F2808, key components, and operation.

Information on the eZdsp’s various interfaces is also included. The eZdspTM F2808consists of four major blocks of logic:

• Analog Interface Connector• I/O Interface Connector• JTAG Interface • USB Port JTAG Controller Interface

2.1 The eZdspTM F2808 Board

The eZdspTM F2808 is a 5.25 x 3.0 inch, multi-layered printed circuit board, poweredby an external 5-Volt only power supply. Figure 2-1 shows the layout of the top side

of the eZdspTM F2808.

Figure 2-1, eZdspTM F2808 PCB Outline


2-3

2.1.1 Power Connector

The eZdspTM F2808 is powered by a 5-Volt only power supply, included with theunit. The unit requires 500mA. The power is supplied via connector P6. If expansionboards are connected to the eZdsp, a higher amperage power supply may benecessary. Section 2.3.6 provides more information on connector P6.

2.2 eZdspTM F2808 Memory

The eZdsp includes the following on-chip memory:

• 2 blocks of 4K x 16 single access RAM (SARAM)• 1 block of 8K x 16 SARAM• 2 blocks of 1K x 16 SARAM

The eZdsp can load ram for debug, or Flash can be programmed and run. For largersoftware projects it is suggested to do a initial debug with on eZdsp F2808 modulewhich supports a total RAM environment. With careful attention to the I/O mapping inthe software the application code can easily be ported to the F2808.

2.4.1 JP4, Voltage Jumper, +3.3/5 Volts for P8, P4

Jumpers JP4 is an unpopulated jumper on the bottom side of the board thatprovide either +3.3 volts or +5 volts to pins on the expansion connector. Thisjumper is shipped uninstalled to prevent accidental damage by connecting wires orcircuitry to the expansion connector. The user may connect the jumper by installinga jumper wire or zero ohm resistor. The position of this jumper is shown in thefigure below.

Jumper JP4 allows the user to provide either +3.3 or +5 volts to pins 1 and 2 ofexpansion connector P8.

The table below shows the functions of the two positions of JP4.

2.4.2 JP5, ADCREFIN Select

Jumper J5 is used to select ADCREFIN as the voltage reference for the analog todigital converter. When the jumper is shorted the +2.048 voltage level is routed to theADCREFIN signal of the DSP. When the jumper is open the ADCREFIN floats.

2.4.3 JP6, GPIO22/GPIO24 Select

Jumper JP6 selects which signal, GPIO22 or GPIO24, to be routed to Pin 33, P8. When the 1-2 jumper position is selected GPIO22 is connected to pin 33, P8. The2-3 selection will route GPIOI24 to Pin 33, P8. The figure below shows the connectorlayout on the bottom side of the board.

2.5.1.2 Switch SW1, Position 4, EEPROM Write Enable/Disable

Position 4 on switch SW1 is used to enable or disable the Write Enable for theEEPROM. When position 4 is in the “Closed” state the Write Protect to the EEPROM isdisabled, therefore allowing the EEPROM to be written. When position 4 is in the“Open” state the EEPROM Write Protect is enabled, not allowing the EEPROM to bewritten. These positions are shown in the table below.

2.6 LEDs

The eZdspTM F2808 has two light-emitting diodes. DS1 indicates the presence of+5 volts and is normally ‘on’ when power is applied to the board. DS2 is under softwarecontrol and is tied to the GPIO34 pin on the DSP through a buffer. These are shown inthe table below.

2.7 Test Points

The eZdspTM F2808 has two test points. The signals they are tied to are shown in thetable below.

eZdspTM F2808 Schematics

The schematics for the eZdspTM F2808 can be found on the CD-ROM thataccompanies this board. The schematics were drawn on ORCAD.

WARNING !The TMS320F2808 supports +3.3V Input/Output levelswhich are NOT +5V tolerant. Connecting the eZdsp toa system with +5V Input/Output levels will damage theTMS320F2808. If the eZdsp is connected to anothertarget then the eZdsp must be powered up first and powered down last to prevent lactchup conditions.
