Introduction
15
November 2002 Revised January 2005
SPRS205D
The TMS320C55x DSP core was created with an open architecture that allows the addition of
application-specific hardware to boost performance on specific algorithms. The hardware extensions on the
5509A strike the perfect balance of fixed function performance with programmable flexibility, while achieving
low-power consumption, and cost that traditionally has been difficult to find in the video-processor market. The
extensions allow the 5509A to deliver exceptional video codec performance with more than half its bandwidth
available for performing additional functions such as color space conversion, user-interface operations,
security, TCP/IP, voice recognition, and text-to-speech conversion. As a result, a single 5509A DSP can power
most portable digital video applications with processing headroom to spare. For more information, see the
TMS320C55x Hardware Extensions for Image/Video Applications Programmer’s Reference
(literature
number SPRU098). For more information on using the the DSP Image Processing Library, see the
TMS320C55x Image/Video Processing Library Programmer’s Reference
(literature number SPRU037).

Pin Assignments
Figure 21 illustrates the ball locations for the 179-pin ball grid array (BGA) package and is used in conjunction
with Table 21 to locate signal names and ball grid numbers.
DV
DD
is the power supply for the I/O pins while CV
DD
is the power supply for the core. V
SS
is the ground for
both the I/O pins and the core. RCV
DD
and RDV
DD
are RTC module core and I/O supply, respectively. USBV
DD
is the USB module I/O (DP, DN, and PU) supply. ADV
DD
is the power supply for the digital portion of the ADC.
AV
DD
is the power supply for the analog part of the ADC. ADV
SS
is the ground pin for the digital portion of the
ADC. AV
SS
is the ground pin for the analog part of the ADC. USBPLLV
DD
and USBPLLV
SS
are the dedicated
supply and ground pins for the USB PLL, respectively.
