2.0 The eZdspTM F2804x Operation
This chapter describes the eZdspTM F2804x, key components, and operation.
Information on the eZdsp’s various interfaces is also included. The eZdspTM F2804x
consists of four major blocks of logic:
• Analog Interface Connector
• I/O Interface Connector
• JTAG Interface
• USB Port JTAG Controller Interface
2.1 The eZdspTM F2804x Board
The eZdspTM F2804x is a 5.25 x 3.0 inch, multi-layered printed circuit board, powered
by an external 5-Volt only power supply. Figure 2-1 shows the layout of the top side
of the eZdspTM F2804x.

2.1.1 Power Connector
The eZdspTM F2804x is powered by a 5-Volt only power supply, included with the
unit. The unit requires 500mA. The power is supplied via connector P6. If expansion
boards are connected to the eZdsp, a higher amperage power supply may be
necessary. Section 2.3.6 provides more information on connector P6.
2.2 eZdspTM F2804x Memory
The eZdsp includes the following on-chip memory:
• 2 blocks of 1K x 16 single access RAM (SARAM, M0,M1)
• 1 block of 8K x 16 SARAM (Lo,L1)
The eZdsp can load ram for debug, or Flash can be programmed and run. For larger
software projects it is suggested to do a initial debug with on eZdsp F2804x module
which supports a total RAM environment. With careful attention to the I/O mapping in
the software the application code can easily be ported to the F2804x.
