2.1.1 Power Connector
The eZdsp
TM
F2808 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 eZdsp
TM
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 larger
software projects it is suggested to do a initial debug with on eZdsp F2808 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 F2808.
